Caterpillar D7R

Maintenance schedule, common problems & OEM parts breakdown

The Cat D7R is a mid-size (Class II) track-type tractor bulldozer that Caterpillar built from 1996 to 2010 across two series, replacing the D7H. The original D7R (1996-2001) runs a turbocharged and aftercooled Cat 3306 diesel rated around 171 kW (230 hp) net; the D7R Series II (2001-2010) switched to the electronically controlled Cat 3176C rated around 179 kW (240 hp) net. Operating weight spans roughly 20.5 to 26 metric tons (about 45,000 to 57,000 lb) depending on series, blade, and undercarriage configuration. Cat offered the D7R in standard, XR (extended-frame, traction-focused for skidding, ripping, and drawbar work), and LGP (low ground pressure, wide-gauge) arrangements, with straight, semi-U, U, and angle blade options plus an optional ripper. Power reaches the tracks through a 3-speed powershift transmission and torque converter with differential steering, which keeps power flowing to both tracks through a turn instead of braking one side.

Series II's move to the electronic 3176C added roughly 8 kW (10 hp) over the Series I 3306 and brought ECM-based clutch and injection control, which improved diagnostics and shift quality but also introduced ECM-matching issues that show up after an engine swap. Series II also refined the undercarriage, adding an optional Rotating Bushing Track that seals and lubricates the bushing-sprocket interface to slow wear on high-hour production machines. Caterpillar phased the R-series out for the electric-drive D7E around 2009, then replaced that whole D7E/D7R generation with an all-new, higher-drive D7 in 2020. That leaves the D7R generation in a well-defined used-equipment window: enough units are still working that engine, powertrain, and undercarriage parts stay in active supply, and its conventional torque-converter and powershift drivetrain is simpler and cheaper to rebuild than the electric-drive machines that followed it, which keeps it attractive to owner-operators and rental fleets running production dozing, land clearing, and ripping work.

Caterpillar D7R specifications

Engine

Engine generationsThe D7R nameplate was built with three different engines over its production life. Confirm the fitted engine against the serial/engine plate before quoting parts, since ratings and displacement differ between them.
Early production engineCat 3306T, 6-cylinder turbocharged diesel. Gross power 184 kW (247 hp), net power 172 kW (230 hp) at 2100 rpm. Displacement 10.5 L (638 cu in).
Series II engineCat 3176C, 6-cylinder turbocharged diesel with mechanically actuated, electronically controlled unit injection. Gross power 192 kW (258 hp), net power 179 kW (240 hp) at 2100 rpm. Displacement 10.3 L (629 cu in).
Later/export production engineCat C9 with ACERT technology, 6-cylinder turbocharged, air-to-air aftercooled (ATAAC) diesel with HEUI hydraulic-electronic unit injection. Gross power 204 kW (274 hp) per ISO 14396, net power 194 kW (260 hp) per ISO 9249, rated at 1900 rpm. Bore 112 mm (4.4 in), stroke 149 mm (5.9 in), displacement 8.8 L (537 cu in).
EmissionsEarliest production predates formal emissions tiering for this power class. The 3176C-powered generation and the later C9 ACERT generation are built to EPA Tier 2 / EU Stage II equivalent levels; the C9 ACERT version is additionally certified to China Stage II (GB 20891-2007).
Altitude derating (C9 ACERT)No derating required up to 2286 m (7,500 ft). Automatic derating occurs above that altitude.

Performance

Travel speed, forward, 1st/2nd/3rd gear3.5/6.1/10.5 km/h (2.2/3.8/6.6 mph). Later configurations report a maximum forward speed around 6.6–6.8 mph (10.6–10.9 km/h); treat as generation/config variance.
Travel speed, reverse, 1st/2nd/3rd gear4.5/7.9/13.6 km/h (2.8/4.9/8.4 mph). Maximum reverse speed reported in the 8.4–8.6 mph (13.5–13.8 km/h) range depending on generation.
TransmissionPlanetary power shift transmission, 3 speeds forward and 3 speeds reverse, with a torque divider splitting engine torque between a torque-converter path and a direct-drive path, paired with differential steering controlled by a single tiller-bar lever.
Ground pressure, standard track – Standard configurationApproximately 74–76 kPa (10.8–11.1 psi).
Ground pressure, standard track – XR configurationApproximately 68–73 kPa (9.8–10.6 psi); XR ground pressure shows the widest spread between generations of the three configurations.
Ground pressure, standard track – LGP configurationApproximately 46 kPa (6.6 psi), consistent across generations.
Ground contact area – Standard/XRApproximately 3.2–3.4 m² (4,972–5,280 in²) depending on generation and track arrangement.
Ground contact area – LGPApproximately 5.8–5.9 m² (9,000 in²).
Drawbar pullPeak drawbar pull in 1st gear at near-zero travel speed reaches roughly 550–600 kN (124,000–135,000 lbf) per the factory pull-versus-speed curve, tapering off through 2nd and 3rd gear as travel speed rises. Usable pull depends on the tractor's actual operating weight, configuration and underfoot traction.
GradeabilityNot published as a standalone percentage or degree figure for this model; drawbar performance is expressed through the pull-versus-speed curve above rather than a single grade rating.
Hydraulic pumpVariable-displacement piston pump. Main hydraulic relief pressure setting approximately 42,000 kPa (6,092 psi). Pump output flow ranges roughly 177–295 L/min (47–78 gal/min) depending on generation and configuration.
Hydraulic maximum operating pressure – bulldozer/ripper lift circuitsApproximately 22,750 kPa (3,300 psi).
Hydraulic maximum operating pressure – bulldozer tilt circuitApproximately 17,225 kPa (2,500 psi).
Hydraulic maximum operating pressure – steering circuitApproximately 38,000 kPa (5,511 psi).

Blades

Semi-Universal (SU) blade – Standard/XR configurationCapacity 6.86 m³ (8.98 yd³); width 3693 mm (145.4 in); height 1524 mm (60 in); digging depth 527 mm (20.7 in); maximum tilt 799 mm (31.5 in); weight without hydraulic controls about 3593 kg (7,923 lb).
Angle (A) blade – Standard/XR configurationCapacity 3.89 m³ (5.08 yd³); width 4496 mm (177 in) straight, reducing to 4120 mm (162 in) when angled 25 degrees; height 1111 mm (43.7 in); digging depth 669 mm (26.3 in); maximum tilt 627 mm (24.7 in); weight about 3523 kg (7,768 lb).
Straight (S) blade – LGP configurationCapacity about 5.9 m³ (7.70 yd³); width 4545 mm (179 in); height 1343 mm (53 in); digging depth 668 mm (26.3 in); maximum tilt 686 mm (27 in); weight about 3732 kg (8,229 lb).
Blade mounting and controlTag-link mounting brings the blade closer to the tractor for balance and penetration and carries side loads into the mainframe rather than the push-arms. Blade lift and tilt use load-sensing, pilot-operated hydraulics.
Blade capacity measurement standardCapacities are rated to SAE J1265 recommended practice.

D7R fluids & capacities

SystemCapacityRecommended fluid
Engine crankcase (with filter)About 27-31 L (7.3-8.2 US gal) depending on series/build. Early D7R (3306 turbocharged engine) and later production D7R (C9 ACERT engine) charts cluster around 27.3-28 L (7.3-7.4 gal); some D7R Series II spec charts list up to 31 L (8.2 gal). Confirm exact figure against the OMM for your serial prefix.Cat DEO or DEO-ULS diesel engine oil. SAE 10W-30 is the preferred year-round grade for this engine family across roughly -18°C to 40°C (0°F to 104°F) ambient. Use 0W-40 or 5W-40 for cold starts down to about -30°C to -40°C, or 15W-40 for sustained heat up to 50°C.
Cooling systemAbout 73-77 L (19.3-20.4 US gal); figure varies slightly by series and radiator/fan configuration.Cat ELC (Extended Life Coolant), premixed. Cat DEAC (Diesel Engine Antifreeze/Coolant) is the alternate, but needs periodic Supplemental Coolant Additive treatment that ELC does not.
Fuel tank479 L (126.5 US gal).No. 2-D ultra-low-sulfur diesel meeting Cat's fuel spec. No. 1-D or a winter-blend diesel is recommended when ambient temperature runs below freezing to avoid fuel waxing/gelling.
Transmission / power train (planetary powershift transmission, bevel gear case and steering clutches)About 178-182 L (47-48.1 US gal) total. On this machine the transmission, bevel gear case and steering clutches share one common power-train oil supply, so factory refill charts publish a single combined figure rather than separate transmission-only and bevel-gear-only capacities.Cat TDTO (Transmission/Drive Train Oil). SAE 30 covers the normal ambient range; use SAE 10W or Cat Arctic TDTO for cold starts down to roughly -20°C (-4°F), and SAE 50 for sustained high ambient heat.
Final drives (each side)13 L (3.4-3.5 US gal) per side.Cat TDTO, same SAE-grade selection by ambient temperature as the power train compartment.
Hydraulic system / tank54 L (14.3 US gal), hydraulic tank only (implement/attachment hydraulic circuit).Cat HYDO Advanced 10 is preferred across roughly -20°C to 40°C (-4°F to 104°F). Cat TDTO, Cat Arctic TDTO, or Cat MTO are listed as acceptable alternates depending on ambient range.
Pivot shaft (equalizer bar) compartmentNot consistently documented across factory spec tables for this model - figures seen range from roughly 1.9 L (0.5 US gal) up to roughly 32 L (8.5 US gal). Treat as unconfirmed; check the OMM lubricant/refill chart for your specific serial number before servicing.Cat TDTO, same viscosity selection as the power train compartment.
Grease (chassis lubrication points)No bulk refill capacity - serviced fitting by fitting per the machine's lubrication chart, not a reservoir fill.Cat Multipurpose grease, NLGI 2, for normal ambient conditions. Cat Advanced 3Moly or Cat Ultra 5Moly grease for heavily loaded pin/bushing joints where specified. Cat Arctic Platinum grease (NLGI 0) for sustained cold below about -20°C (-4°F); Cat Desert Gold grease (NLGI 2) for sustained heat.

Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Caterpillar D7R maintenance schedule

Service intervalTasks
Every 50 h
  • Walk around the machine before startup and check for fuel, oil, and coolant leaks around the engine, torque converter housing, and final drives.
  • Check engine oil and coolant levels with the machine parked on level ground, and drain water and sediment from the fuel tank and water separator.
  • Check track sag between the sprocket and idler and adjust the recoil spring compartment if slack has grown.
  • Grease the blade lift arm, tilt cylinder, and C-frame pivot points.
  • Confirm gauges, backup alarm, and seat belt function before moving the machine.
  • Clear debris packed on top of the track roller frame and around the carrier rollers.
Every 250 h
  • Change engine oil and filter with a Cat DEO-class oil in the 3306 or 3176C unless an S·O·S sample supports extending the drain.
  • Inspect and adjust the alternator and fan drive belts.
  • Service the primary and secondary fuel filters.
  • Clean the engine crankcase breather.
  • Pull an S·O·S sample from the powertrain case and hydraulic tank for trending.
Every 500 h
  • Change the hydraulic implement system oil filter.
  • Check final drive oil level at each side case.
  • Inspect the differential steering and brake system for correct actuation travel.
  • Grease the equalizer bar and track roller frame pivots.
  • Inspect sprocket segments and idlers for mushrooming or ridging wear.
Every 1,000 h
  • Change the powertrain oil, a Cat TDTO-class fluid shared by the transmission, torque converter, steering differential, and final drives.
  • Replace the hydraulic tank breather and check hoses for chafing or soft spots.
  • Clean the radiator and oil cooler cores of packed debris.
  • Check track shoe bolt torque and inspect master link condition.
  • Inspect the turbocharger for shaft play, oil leakage, and boost-side piping condition.
Every 2,000 h
  • Change the hydraulic tank oil with a Cat HYDO-class fluid.
  • Change engine coolant if the machine runs a conventional, non-extended-life formulation.
  • Review ECM clutch-pressure and solenoid trend data on Series II machines for early transmission clutch pack wear.
  • Check and adjust engine valve lash.
  • Measure undercarriage bushing, link, and sprocket wear to plan a track turn or rotation.
Every 6,000 h
  • Change Cat ELC extended-life coolant, or verify corrosion inhibitor level if still running conventional coolant past its rated life.
  • Schedule a full engine top-end inspection covering valve lash, injectors, and the turbocharger core.
  • Inspect the torque converter and transmission clutch packs to decide on a rebuild.
  • Evaluate the undercarriage as a full system, chain, rollers, idlers, and sprocket segments together, rather than swapping single components.
  • Compile powertrain and engine oil sample trends to decide whether a certified rebuild is due before a failure forces it.

Servicing the D7R beyond the schedule

Predictive Maintenance & Fluid Analysis

Pull S·O·S oil samples from the engine, torque converter/powertrain case, and hydraulic tank at every scheduled interval, not just at oil changes. On Series II machines, trend the ECM's clutch-pressure and solenoid data to catch a failing transmission clutch pack before it strands the machine mid-shift. Watch iron and silicon counts in the powertrain sample closely: that compartment shares oil across the torque converter, transmission, steering differential, and final drives, so one worn component shows up across the whole trend line.

Corrective & Common Repairs

Most D7R downtime traces to the powertrain and steering system, not the engine. Watch for transmission clutch solenoid faults blocking forward or reverse engagement, especially after an engine or ECM swap left uncalibrated to the drivetrain. Differential steering wears gradually rather than failing outright; a machine pulling to one side under load usually needs a steering clutch or brake adjustment, not a rebuild. Check final drive and torque converter housing seals at every service. On the 3306, a worn turbocharger shaft seal shows up as blue exhaust smoke at idle.

Overhaul & Rebuild Points

A D7R nearing a certified rebuild needs the undercarriage, powertrain, and engine assessed together, since track and drivetrain wear compound each other. Plan on the torque converter, transmission clutch packs, steering differential bearings, and final drive gear sets as one job. On the engine side, the 3306's cylinder liners and turbocharger core are the highest-wear top-end items; the 3176C on Series II adds electronic unit injectors to that list. Weigh a Rotating Bushing Track upgrade against standard chain on Series II undercarriages, since RBT slows sprocket wear on high-hour machines.

Seasonal & Environment Servicing

Cold-climate D7Rs need coolant glycol protection verified and starting aids serviced before winter, since the turbocharged 3306 or 3176C is hard to start once temperatures drop. In hot, dusty applications, service air filters more often and keep the radiator and oil cooler cores clear of packed debris that raises operating temperature across the torque converter and hydraulics. LGP machines working wet or swampy ground need more frequent undercarriage cleanout, since wide shoes and long frames pack mud between rollers and track links faster than standard-gauge machines.

D7R attachments & work tools

Blades

Factory dozer blades for the D7R are the Semi-Universal (SU) for load retention and penetration in packed material, an Angle blade set straight or manually pinned to about 25 degrees either side for side-casting, ditching, and road pioneering, and a Straight blade offered on the LGP undercarriage for aggressive cutting in heavier material. Earlier Series 2-era literature also lists a taller Universal (U) blade and a Straight blade for Standard/XR undercarriage; later export documentation narrows the Straight blade to LGP only, so exact lineup varies by configuration/series. Capacities run roughly 3.9 m3 (5.1 yd3) on the Angle blade up to about 6.9-8.3 m3 (9.0-10.9 yd3) on SU/Universal blades, with widths over end bits spanning roughly 3.7-4.5 m (145-179 in) depending on blade type and generation. VPAT (variable pitch/angle/tilt) is not a catalog option on this machine - that feature belongs to Cat's compact track loader and grader lines, not the medium track-type tractor range. Landfill/waste blade variants with an integral trash rack are offered on SU and LGP straight-blade frames for high-debris work.

Rippers

The D7R rear ripper is an adjustable multi-shank parallelogram design with hydraulic lift, tilt, and shank-angle control; shank positions can be run individually or together, so a lighter single-shank setup is achieved by loading fewer positions on the same frame rather than fitting a separate ripper model. Fully loaded weight is documented in the roughly 3.3-3.6 tonne (7,350-7,950 lb) range, varying by source/generation. Maximum shank penetration is about 750 mm (29.5 in) with penetration force near 85 kN (19,100 lbf) and pryout force near 177 kN (39,700 lbf); the transmission and differential are designed to slide out the rear case for service even with the ripper mounted.

Winches

Cat does not sell an in-house winch for the D7R - literature for this model directs buyers to a dealer-selected winch OEM supplier rather than a factory unit, historically including PTO-driven and hydraulic winch builders serving this dozer class. Two general classes fit the D7R: a PTO-driven (torque-converter-tap) winch, which gets higher line pull through torque multiplication, and a hydraulically driven winch, which gives finer reel-in/reel-out control for load spotting. A factory weight allowance for a winch plus its control is documented at roughly 1.8-1.9 tonne (4,050-4,200 lb) combined, and fitting a winch adds about 77 mm (3 in) to overall tractor length.

Drawbars/Counterweights

A rigid rear drawbar (about 234 kg / 516 lb) is available for compactors, chopper wheels, pull-type scrapers, and machine-retrieval work when the rear striker bar is not carrying a ripper or winch. Drawbar height (grouser tip to clevis center) runs about 634 mm (24.9 in) on Standard/XR undercarriage and about 713 mm (28.1 in) on LGP. A rear counterweight (about 1.06 tonne / 2,340 lb) plus an additional counterweight slab (about 345 kg / 761 lb) are offered to rebalance the tractor for backing on steep slopes or for heavy dozing, and are the recommended fit whenever no other rear attachment is specified.

Cab/ROPS Guarding

Standard cab is an integrated ROPS/FOPS structure with laminated glass and a work-tool hydraulic lockout switch. For forestry, side-slope, rocky, and other high-impact ground the machine's heavy-duty undercarriage is explicitly called out for that duty, and several guarding packages support high-debris work: a Waste Handling package (roughly 2.1 tonne / 4,630 lb, offered for both Standard and LGP) bundles a sealed/ducted alternator, crankcase and louvered radiator guards, final-drive and idler seal guards, a screened precleaner, thermal shielding, dozer line and chassis guards/seals, heavy-duty handles, and a rear striker bar carrying rear counterweight with a trash-resistant radiator and ejector fan. A separate Sweeps package adds a rear sweep, supplemental lighting, and guarding for a ROPS cab or canopy, and a Stockpile package (turbine precleaner, solid engine hood, trash-resistant radiator, ejector fan, extra lighting and alternator capacity, cab-mounted A/C) targets similarly abrasive, dusty conditions. Rear and side screens and clamshell-style guarding are also field-installable for wrap and impact protection.

Hydraulic Arrangement

Hydraulics are load-sensing and pilot-operated, drawn from one variable-displacement piston pump that feeds both the front dozer circuit (lift and tilt) and the rear ripper circuit (lift, tilt, and shank angle). Documented flow is about 190 L/min (50 gal/min) to the lift and ripper circuits and about 80 L/min (21 gal/min) to the tilt circuit, with a main relief setting near 42,000 kPa (6,090 psi). An electronic work-tool lockout isolates the hydraulic work-tool circuits against inadvertent movement, and when Cat's automated grade-control system is engaged the dozer circuit switches to electro-hydraulic control, reverting to standard pilot-hydraulic control when the operator takes back manual control.

D7R serial number reference

The D7R PIN plate is mounted on the main frame rail, usually on the right side near the front of the machine or at the operator's step/ROPS mount, stamped or riveted with the full Product Identification Number. Read the first three characters as the serial prefix, which ties the machine to its model, configuration, and production block; the remaining five digits are the sequential unit number within that block, not a model year.

Frequently asked questions

What engine does the Cat D7R use?

The Series I D7R (1996-2001) uses a turbocharged and aftercooled Cat 3306 diesel, rated around 171 kW (230 hp) net. The D7R Series II (2001-2010) switched to the electronically controlled Cat 3176C, rated around 179 kW (240 hp) net. Confirm which engine is fitted by series/serial number before ordering parts.

What is the operating weight of the Cat D7R?

Operating weight runs roughly 20.5 to 26 metric tons (about 45,000 to 57,000 lb), and it varies by series and configuration. Standard and XR machines sit toward the lighter-to-middle end of that range; LGP machines with wider tracks and longer frames run heavier.

What replaced the Cat D7R?

Caterpillar moved the line to the electric-drive D7E starting around 2009, then replaced the whole D7E/D7R generation with an all-new D7 in 2020 that uses a higher-drive undercarriage and a different engine and transmission architecture.

What D7R owners discuss

What engine does a D7R actually have, and does it change by series?
Early D7R models run a mechanical, turbocharged 3306 inline six of about 10.5 L (640 cu in) displacement, rated around 172 kW (230 hp) flywheel power. Series II D7R machines switched to the electronically controlled 3176C, about 10.3 L (629 cu in), rated near 179 kW (240 hp) net and 192 kW (258 hp) gross. Confirm the engine off the serial plate rather than assuming by model year, since production overlap exists between the two. The mechanical 3306 has a reputation among owners for long service life with basic maintenance; the 3176C trades that simplicity for electronic fuel control and the sensor and ECM dependencies that come with it.
Why does the transmission or torque converter run hot on a D7R, and how worried should I be?
The D7R splits engine torque between the converter and a direct drive shaft rather than running everything through fluid coupling, which keeps heat down compared to a full hydraulic drive. Even so, owners have reported converter oil temperatures creeping past roughly 125°C (257°F) under sustained heavy pushing, usually alongside noticeable oil leakage from the transmission compartment. A worn or slipping clutch pack, low oil level, or a plugged transmission oil cooler are the usual culprits. If a caution light or buzzer comes on and the machine de-rates or won't come out of first gear, stop and have your dealer verify oil condition, cooler flow, and clutch pack pressures before continuing to work the machine hard.
The machine shifts fine on the monitor but won't actually move in most gears. What's going on?
Techs report cases where a D7R takes shift commands fine with no active fault codes, yet only moves in one gear or won't move in reverse at all. Before assuming a bad clutch pack or valve body, check the brake and transmission control manifold under the seat. Worn O-rings or debris there can block oil flow to the clutches it feeds even though the electronics check out. A clean ECM flash, solenoid recalibration, and fresh transmission oil are worth trying first, but if those don't resolve it, the manifold is the next place to look. Because this affects the machine's ability to move and stop, have your dealer verify the repair before returning it to service.
Does the D7R's elevated sprocket design change how the undercarriage wears?
The elevated final drive keeps the sprocket up off the ground away from impact loading, which is generally credited with lower shock wear on the drivetrain versus a low-sprocket dozer working the same rocky or abrasive ground. That design doesn't stop normal wear, though. Working life still depends heavily on ground conditions, how much ripping versus straight dozing the machine does, and whether track sag is kept in spec at the midpoint between idler and sprocket. Sag that's too tight accelerates wear; too loose invites derailing. Uneven side-to-side wear usually traces back to sag or alignment rather than the elevated design itself.
What's the warning sign that a final drive or steering clutch and brake seal is failing?
A duo-cone or floating seal that starts weeping oil lets contamination work into the bearings and planetary gearing, and once that starts, a machine can go from a simple seal repair to a full internal rebuild within hours of continued heavy use. On the steering clutch and brake side, the most common source of oil fouling in those compartments isn't the clutch pack itself, it's a leaking final drive pinion seal or bevel gear shaft seal dribbling into the adjacent brake drum area. Any oil weeping at the final drive housings or brake covers is worth chasing down right away. Have your dealer verify seal condition before it turns into contamination damage on the steering or braking components.
On Series II machines with the electronic 3176C engine, what sensor or electrical issues come up?
The 3176C's HEUI fuel system needs stable ECM power and clean grounds to fire reliably. Owners report intermittent no-start or hard-start conditions traced to cranking voltage sagging at the ECM, often a battery, connection, or grounding issue at the starter or the deadman safety switch rather than the ECM itself. A failed engine speed or timing sensor is another documented cause of hard starting, since the ECM needs that signal to set injection timing. The HEUI pump can also weep oil at its rear shaft seal over time, which can eventually let oil migrate into the fuel side. Because a no-start on this system can be electrical, sensor based, or hydraulic, have your dealer pull ECM logged codes and check cranking voltage before parts get swapped.
What should I check before buying a used D7R?
Confirm which engine and series is actually fitted, mechanical 3306 or electronic 3176C on Series II, since parts support and overhaul cost differ between them. Check indicated hours against physical wear: pedals, joystick, seat cushion, floor plate, and access steps that look more worn than the hour meter suggests are a red flag. Inspect the undercarriage for uneven or excessive wear and confirm track sag is in spec, since undercarriage condition drives a large share of total ownership cost on this class of dozer. Look over the blade, cutting edge, and trunnion pins for wear, and check for weld lines or patch plates on the blade that point to prior repairs. Cycle the blade and ripper fully; smooth, consistent movement is normal, and gradual slowing under load points to internal pump or cylinder wear. Check for oil weeping at the final drives, steering clutch and brake housings, and around the HEUI pump area on Series II machines. Have your dealer verify undercarriage condition and transmission or brake history before you finalize the purchase.
