Caterpillar 973D

Maintenance schedule, common problems & OEM parts breakdown

The Caterpillar 973D is a large track-type loader, not a bulldozer: it carries General Purpose (GP) or Multi-Purpose (MP) buckets on a Z-bar loader linkage rather than a dozer blade. Power comes from the Cat C9 ACERT, an 8.8 L six-cylinder diesel rated at 196 kW (263 hp) with HEUI electronic fuel injection and ADEM ECM control, meeting Tier 3/Stage IIIA emissions with no aftertreatment or DEF system. Operating weight runs from about 28,058 kg (61,857 lb) for the Standard Track Loader up to about 29,555 kg (65,157 lb) for the Waste Handler package, depending on bucket and configuration. Cat built the 973D in the mid-to-late 2000s as the update to the 973C and continued production into the mid-2010s, with dates varying by source and market, so verify the exact build year by serial number. Drive is an electronically controlled Hystat (hydrostatic) system, with independent variable-displacement pumps and motors driving each track and no torque converter or powershift gearset. Cat offered the platform in Standard and Wide Gauge/LGP track configurations plus several factory application packages on the same chassis: Waste Handler (WH), Waste Handler Extreme Service (WH ES), Steel Mill, and Shiphold/Port Handling (SH), along with an optional 3-shank parallelogram ripper and a rear counterweight package.

The step from the 973C to the 973D brought ACERT-tier electronic engine control and a closed-center, load-sensing implement hydraulic system to the same basic Hystat-driven chassis, replacing the 973C's older mechanical 3306-family engine. All standard, Wide Gauge, Waste Handler, and Shiphold variants share a single documented serial prefix, so identifying the exact configuration on a used machine comes down to the data plate and order specification rather than the serial series. In the used and parts market, the 973D remains a recognizable heavy-duty loader for load-and-carry work, landfill and demolition service, and any application where a wheel loader can't handle the ground conditions. Its Tier 3 engine with no DEF system to maintain is a draw for buyers who want to avoid aftertreatment headaches, while the C9 ACERT's parts commonality across other Cat construction and on-highway platforms keeps engine sourcing reasonably straightforward. Undercarriage and Hystat drive-component wear are the biggest factors in resale value on a machine this heavy, so buyers weigh remaining track and pump/motor life heavily against hour meter readings.

973D fluids & capacities

SystemCapacityRecommended fluid
Engine crankcase (with filter) — Cat C9 ACERT, 8.8 L displacement29 L (7.7 US gal)Cat DEO (Diesel Engine Oil). SAE 10W-30 covers most ambient ranges (roughly -18°C to 40°C / 0°F to 104°F); step up to SAE 15W-40 in consistently warm climates. For cold starts below about -20°C (-4°F) a full-synthetic Cat DEO-ULS SYN grade is called for. Always check oil level with the machine parked level and the engine stopped.
Cooling system44 L (11.6 US gal)Cat ELC (Extended Life Coolant) is the factory-fill coolant on this machine. A factory-installed extreme-cold antifreeze option rated to -50°C (-58°F) is offered for severe climates. ELC should not be mixed with conventional coolant types.
Fuel tank621 L (164 US gal)Clean ultra-low-sulfur No. 2-D diesel; switch to No. 1-D or a winter-blended fuel in cold climates for better cold-flow properties. A fast-fill tank option is available, filling at up to 568 L/min (150 gal/min).
Transmission / power trainCombined with the hydraulic system — no separate transmission sump on this machineThe 973D rides on an electronically controlled Hystat (hydrostatic) drive: two variable-displacement drive pumps feeding two variable-displacement track motors, one per track. There is no powershift transmission and no separate bevel-gear or steering-clutch compartment as on a conventional track-type tractor — drive and steering are done electronically through the hydrostatic circuit, which draws from the same reservoir as the implement hydraulics. Fluid recommendation follows the hydraulic system entry below.
Final drives (each)28.5 L (7.5 US gal)Cat TDTO (Transmission/Drive Train Oil). Grade is picked by ambient temperature — SAE 10W for cooler climates, SAE 30 where sustained high ambient heat is typical, or a multi-season TDTO blend to cover a wider range and cut down on stocked oil types.
Hydraulic system (implement + power train) and hydraulic tankTotal system (implement, power train and tank): 340 L (89.8 US gal). Tank refill alone: 189 L (49.9 US gal)Cat HYDO Advanced 10 is the factory-fill hydraulic oil listed as standard equipment on this machine, formulated for extended drain intervals. A biodegradable hydraulic oil is offered as a factory option for environmentally sensitive sites. This single closed-center, load-sensing reservoir supplies both the implement circuit (lift/tilt) and the Hystat drive circuit.
Pump drive box (accessory/pump drive gearbox)3.8 L (1 US gal)Cat TDTO, same family as the final drives and pivot shaft.
Pivot shaft (equalizer/track-frame pivot)3 L (0.8 US gal)Cat TDTO.
Grease points (loader linkage, cylinder pins, ripper pins)Not a refill volume — serviced by grease gun at scheduled intervalsStandard Cat multipurpose lithium-complex grease (NLGI 2 general duty, e.g. Cat Advanced 3Moly or Cat Extreme Application-type grease) at linkage and cylinder pin points. Track rollers and idlers on this machine are factory sealed and lifetime-lubricated, so they carry no scheduled grease point. In sustained sub-zero climates an arctic-grade grease is substituted at the same points.

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

Caterpillar 973D maintenance schedule

Service intervalTasks
Every 10 h
  • Check engine oil level on the C9 ACERT and top off before starting; check coolant level.
  • Drain water and sediment from the fuel tank water separator and check fuel level.
  • Walk around the machine checking for hydraulic, fuel, or coolant leaks at the engine, HEUI pump, final drives, and hydrostatic drive lines.
  • Inspect the GP/MP bucket cutting edge, teeth, and pivot pins for wear or cracks, and check ripper shanks and tips if fitted.
  • Weekly: grease the Z-bar loader linkage, bucket tilt cylinder, and ripper pivot pins (track rollers and idlers are sealed and lifetime-lubricated, so skip those).
  • Weekly: clean debris from the undercarriage, check track sag using the hydraulic track adjuster, and test the back-up alarm, lights, and horn.
Every 250 h

Servicing the 973D beyond the schedule

Predictive maintenance & fluid analysis

Run Cat S.O.S. sampling on the C9 ACERT engine oil, the Hystat drive and implement hydraulic circuit, and final drive oil at every scheduled interval. Metal in a drive-motor sample or dark, burnt-smelling hydrostatic oil flags pump or motor wear before a track loses power. The HEUI fuel system is sensitive to fuel contamination, so watch injector and HEUI pump trend data closely. Because idler and forward rollers carry the heaviest load on this machine, log undercarriage wear percentages against hours instead of judging by eye.

Corrective & common repairs

Most propel complaints on the 973D trace to the park brake failing to release, not a damaged pump or motor; check hydrostatic charge pressure, oil condition, and the park-brake solenoid first. Hystat drive-motor speed-sensor faults are usually a corroded or pinched connector, not a bad sensor, so clean and reseat before replacing parts. On the C9 ACERT, injector swaps need correct ECM trim codes programmed in or the engine stays rough and down on power. Inspect final-drive and idler seal guards on Waste Handler machines for debris damage.

Overhaul & rebuild points

Major 973D rebuild spend centers on the Hystat drive: reman or overhaul the two variable-displacement drive pumps and two bent-axis track motors once oil analysis shows wear metal or charge pressure drops. Pull C9 ACERT injectors and the HEUI pump for flow testing or exchange at the same window. Track shoes, links, and sprocket segments wear as a set on this heavy loader and are best replaced as a full group. Budget loader-tower and Z-bar linkage pin-bore inspection, plus ripper pivot and cylinder rebuild if fitted.

Seasonal & environment servicing

Cold-climate 973Ds need a block heater and the factory extreme-cold antifreeze option, rated to -50C (-58F); there is no DEF system to protect on this Tier 3 engine. Switch to Cat DEO-ULS SYN oil and a winter-blend diesel below about -20C (-4F). In waste, demolition, or steel-mill duty, inspect the final-drive, pivot-shaft, and idler seal guards and debris baffles often, since these packages exist specifically to keep abrasive material out of the driveline. In dusty sites, service the turbine-type air precleaner and radiator fins more often.

973D fault codes & troubleshooting

CodeMeaningLikely causeWhat to do
100-03 (CID 100 / FMI 03)Engine oil pressure sensor signal reads above the valid range.Open circuit or short to a voltage supply in the oil pressure sensor wiring, a corroded connector, or a failed sensor.Inspect the sensor connector and wiring for damage or corrosion. Confirm actual oil pressure with a manual gauge before replacing the sensor.
110-04 (CID 110 / FMI 04)Engine coolant temperature sensor signal reads below the valid range.Short to ground in the sensor circuit, damaged wiring, or a failed sensor.Inspect wiring and connector for a ground short. Check sensor resistance against spec and replace if out of range.
168-01 (CID 168 / FMI 01)Electrical system voltage reads below the normal operating range.Weak or failing battery, low charging output, corroded battery cables, or a slipping alternator belt.Load-test the batteries, check charging voltage at idle and at rated speed, and inspect ground straps and cable connections.
102-03 (CID 102 / FMI 03)Boost (intake manifold) pressure sensor signal reads above the valid range.Sensor circuit shorted to a voltage source, a damaged harness near the turbo/intake piping, or a failed sensor.Inspect wiring and connector for chafing near the turbocharger and intake piping, then check sensor supply and signal voltage against spec.
190-08 (CID 190 / FMI 08)Engine speed/timing sensor signal frequency is abnormal.Damaged sensor tip, incorrect sensor air gap, debris on the timing wheel, or a wiring fault.Check the sensor gap and mounting, inspect the timing wheel for damage, and test signal wiring for continuity and shielding faults.
651-05 (CID 0651 / FMI 05)Cylinder #1 injector solenoid circuit is open; the ECM cannot fire that injector.Broken or disconnected injector harness, most often where it routes through the valve cover, or a failed injector solenoid.Inspect the injector harness and valve cover connector for oil contamination or damage. Swap the injector with an adjacent cylinder to confirm whether the fault follows the injector or stays with the wiring.
274-04 (CID 274 / FMI 04)Atmospheric (barometric) pressure sensor signal reads below the valid range.Short to ground in the sensor circuit, moisture in the connector, or a failed sensor.Inspect the sensor connector for corrosion, check circuit resistance against spec, and replace the sensor if wiring tests good.
247-09 (CID 247 / FMI 09)SAE J1939 data link communication is abnormal; the engine ECM is not receiving expected messages from another control module on the machine network.Damaged or corroded data link wiring, a powered-down or faulted machine/Hystat control module, or a loose connector on the CAN backbone.Check for a companion code naming the specific module that dropped off the network, then inspect data link wiring and connectors between the engine ECM and the machine control module before replacing any module.

Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.

973D attachments & work tools

Blades

The 973D is a track loader with Z-bar loader linkage, not a dozer, so it does not offer the D-series S/SU/A/VPAT blade lineup. Front tools are General Purpose (GP) and Multi-Purpose (MP) buckets: GP runs 3.21 m3 (4.2 yd3) at 2910 mm (114.6 in) width, MP runs 3.05 m3 (3.92 yd3) at 2868 mm (112.9 in) width. The MP bucket clamps hydraulically and can convert on the fly into a dozer-type blade for spreading cover material; landfill-duty GP/MP buckets scale up to 4.9 m3 (6.4 yd3) and 4.6 m3 (6.0 yd3) at the same widths, and a Wide Gauge package fits a wider bucket with widened track gauge for soft-ground grading and backfilling (exact width varies by order).

Rippers

Caterpillar catalogs one factory ripper for the 973D: a multi-shank (three-shank) parallelogram unit with curved, replaceable-tip shanks, weighing about 1700 kg (3,748 lb) fully equipped. Ripping width is 1840 mm (72.4 in) with 397 mm (15.6 in) penetration and roughly 100 kN (22,500 lbf) penetration force at ground level; shank cross-section is 74 x 175 mm (2.9 x 6.9 in). No single-shank heavy ripper is offered on this loader class (that configuration is typical of larger dozers); fitting the ripper adds about 586 mm (23.1 in) to overall transport length.

Winches

No factory winch package is catalogued for the 973D in Cat literature; rear-end work capability is limited to towing via the heavy-duty bumper's built-in hitch point, not a cable winch drum. Tether-winch setups used for steep-slope landfill work belong to compactors in the waste industry, not this track loader - confirm with your dealer if a winch-equipped variant is genuinely required for a given job.

Drawbars/counterweights

A counterweight package adds about 1460 kg (3,218 lb) to the rear to shift the center of gravity back; Caterpillar recommends it for machines not fitted with a ripper, since the ripper itself (about 1700 kg/3,748 lb) already loads the rear end and the two options are not meant to stack. The rear also gets a heavy-duty bumper and hinged grille with a built-in hitch point for pulling trucks or other equipment, serving as the drawbar provision; a rear striker bar (standard or heavy-duty) keeps debris off the tracks and doubles as an access step.

Cab/ROPS guarding options for forestry/waste configs

Caterpillar does not sell a package named specifically for forestry on the 973D; severe-duty guarding is sold as Waste Handler (WH, for landfills/transfer stations/material recovery) and Waste Handler Extreme Service (WH ES, for demolition and maximum protection, which requires the heavy-duty rear bumper and grille). Both add final-drive, pivot-shaft and idler seal guards, a lift-cylinder/position-sensor guard, heavy-duty hydraulic tank guard, debris-barrier baffles, trash-resistant radiator and an optional hinged windshield screen ahead of the ROPS/FOPS cab glass, and standardize a turbine-type air precleaner that stays optional on the base construction setup. A separate Steel Mill arrangement (heat shields, sealed undercarriage, heat-resistant windshield, fire-resistant fluids) is the closest analog if extreme flying-debris or heat exposure calls for more protection than WH ES.

Hydraulic arrangement notes for front/rear tools

Implement hydraulics are closed-center load-sensing, rated to 346 L/min (91.4 gal/min) maximum flow with a 27500 kPa (3,988 psi) relief setting; cycle times run about 6.5 seconds raise, 1.4 seconds dump and 2.7 seconds float down. Valve arrangement on the option list tracks the tool fitted: a 2-way (2W) circuit covers a plain GP-bucket lift/tilt, a 3-way (3W) circuit adds the function the MP bucket needs for its hydraulic clamp (its steel lines get dedicated guarding on waste-duty machines), and a 4-way (4W) circuit is specified with the MP bucket so a rear-mounted ripper can run its own cylinders independent of the front tool. Plan on at least 3W hydraulics with the MP bucket and 4W once a ripper is added at the rear.

973D serial number reference

The PIN plate is a stamped metal plate riveted to the frame on the left side, on the loader-tower support arm just ahead of the cab; the same PIN is also stamped directly into the frame steel next to the plate as a tamper cross-check against a swapped plate. On the 973D the full PIN reads as CAT plus a model code and configuration digit, followed by the 3-letter serial prefix and an 8-character serial number (e.g. LCP00108); LCP is the prefix that identifies the 973D build series.

Frequently asked questions

What engine does the Caterpillar 973D use?

The 973D runs the Cat C9 ACERT, an 8.8 L six-cylinder diesel rated at 196 kW (263 hp) at 1900 rpm, with HEUI electronic fuel injection and ADEM ECM control. It meets Tier 3/Stage IIIA/Japan MOC emissions with no aftertreatment or DEF system. This engine is documented across both the standard Track Loader and Waste Handler factory literature, replacing the older mechanical 3306-family engine used in the 973C predecessor.

What is the operating weight of the Caterpillar 973D?

Operating weight runs about 28,058 kg (61,857 lb) for the Standard Track Loader and about 29,555 kg (65,157 lb) for the Waste Handler package, with the full range across bucket and configuration choices spanning roughly 27,699-29,553 kg (61,066-65,153 lb). Treat any single figure as configuration-dependent and confirm against the data plate and order specification.

What replaced the Caterpillar 973D?

Cat's next generation in this size class is the 973K, following the same letter-skip pattern Cat used elsewhere in its track loader line (973C to 973D to 973K, mirroring the smaller 963D to 963K step). Treat the 973K as a separate design with its own engine and controls rather than a parts-interchangeable D-series unit.

What 973D owners discuss

How does the 973D's Hystat drive change how it behaves compared to an older torque-converter powershift track loader?
The electronically controlled Hystat system on the 973D drives each track through its own variable-displacement pump and motor circuit, with no torque converter or powershift gearset in the loop. Owners note this gives infinitely variable ground speed, smooth directional changes, and true counter-rotation for tight spins, plus the ability to power both tracks through a turn instead of clutching one side like older drivetrains. One quirk operators flag: if the machine shows drive on one track only, or refuses to propel while every other function (lift, tilt, engine) still works fine, that usually points to the park brake failing to release rather than a damaged pump or motor - commonly traced to low charge pressure, contaminated hydrostatic oil, or a stuck park-brake solenoid. Because an unreleased or unexpectedly releasing park brake is a safety item, have your dealer verify brake release pressure before putting the machine back to work.
What undercarriage wear patterns should I expect on a 973D given how heavy this machine is?
As one of the heaviest machines in the track-loader class, owners report the idler and forward rollers take the brunt of wear because so much static and dynamic weight sits over the bucket end during loading. The oscillating track-roller-frame design is generally praised for smoothing ground shock and reducing pin-and-bushing pounding compared to a rigid frame, but sprocket segments, track pads, and idler bearings still wear faster than on a similarly sized dozer because the machine spends more time counter-rotating and cross-loading the tracks during load-and-carry cycles. Community consensus is to price remaining undercarriage life into any deal rather than judge it by eye, since wear item replacement on a machine this size adds up quickly.
Are there known quirks with the C9 ACERT engine used in the 973D?
The 973D runs the C9 ACERT diesel, rated around 196 kW (263 hp) net, a hydraulically actuated electronically controlled unit injector (HEUI) design shared across several Cat construction and on-highway platforms. Across that engine family, the most frequently reported quirks are: injectors and the HEUI pump are sensitive to fuel contamination and will lose power or smoke before failing outright; injector replacement generally needs correct trim codes programmed into the ECM, or the engine idles rough and stays down on power even with good injectors installed; and metal shed from a failing HEUI pump can take out injectors downstream, so a pump found making metal warrants a full fuel-system inspection rather than just an injector swap. None of this is unique to the 973D chassis - it comes with the shared engine platform, so keep fuel cleanliness and filtration intervals tight.
What electrical or sensor issues come up on Hystat-drive Cat track loaders like the 973D?
The recurring theme across Cat's electronically controlled Hystat lineup is drive-motor speed-sensor faults: the ECM needs a clean frequency signal from each drive motor's speed sensor to control propel smoothly, and when that signal drops out the machine will fault or hunt instead of driving cleanly. Mechanics report the sensor itself is rarely the actual failure - more often it's corrosion or a pinched or broken wire at the connector between the sensor and the main harness. Cleaning the sensor nose and reseating or replacing the connector resolves the fault more often than replacing the sensor outright. Because these faults sit in the propulsion control loop, have your dealer verify the repair with an active test drive and a code check before relying on the machine in tight quarters.
Do owners prefer the joystick or pedal steering setup on the 973D?
Operators are split, and it shows up repeatedly in community discussion. The pedal ("V") layout separates direction from steering, which owners find precise for fine grading and edge work, but working the pedals for steering all day can leave an operator with leg fatigue by the end of a shift. The single-joystick option combines direction and steering in one hand, cutting leg fatigue, but several operators say it is less precise for feathering a turn and can bring on wrist strain over a long day. The general consensus is that preference comes down to what the operator learned on first rather than one layout being objectively better.
What kind of fuel consumption should I expect running a 973D all day?
Owners describe the 973 platform as thirsty relative to a comparable wheel loader or a smaller Cat track loader, which tracks with a roughly 196 kW (263 hp) engine moving a heavy machine through load-and-carry or push work all day. Reported burn rates vary a lot by duty cycle, material, and operating technique, so treat any single number as anecdotal rather than a spec - plan fuel budgets closer to a large dozer than a mid-size wheel loader.
What should I check before buying a used 973D?
Community advice converges on the same short list. Pull an actual undercarriage wear percentage instead of trusting a visual "still has life in it" impression, since segment, roller, and idler wear on a machine this heavy adds up fast. Check the color and smell of the hydrostatic drive oil - dark or burnt-smelling oil is a red flag for internal pump or motor wear. Verify the machine powers and steers evenly in both directions and across a slope, not just in a straight line on flat ground, since weak propel on one side more often points to a hydrostat or park-brake problem than an engine issue. Ask for service records and a recent fluid sample analysis rather than relying on the hour meter and paint condition. Because propel and brake faults can be masked as "just needs a service," have your dealer verify hydrostatic charge pressure and park-brake release before you commit to the purchase.
