Caterpillar MT845
Maintenance schedule, common problems & OEM parts breakdown
The Caterpillar-lineage Challenger MT845 is a high-horsepower, rubber-belted (Mobil-trac) row-crop and tillage track tractor built under the AGCO Challenger brand after Caterpillar sold its agricultural tractor line in 2002. It sits mid-pack in the MT800 Series, above the MT835 and below the MT855/MT865, aimed at primary tillage, seeding, and scraper pulling above 280 kW (380 hp). Engine and rating varied by suffix: the original MT845 (2002-2004) ran a Cat C12 (11.9 L) inline-six at 283 kW (380 hp) gross; the MT845B (2005-2008) stepped up to a Cat C15 (15.2 L) at 298 kW (400 hp); the Tier III MT845C (2009-2013) carried a Cat C15 ACERT at 328 kW (440 hp); and the final MT845E (2014-2020) dropped Caterpillar power entirely for an AGCO Power 16.8 L V12 rated around 336-343 kW (450-460 hp). Operating weight climbed from roughly 18.1 tonnes (40,000 lb) at launch to about 19.3-19.5 tonnes (42,600-43,075 lb) by the later series, and belt width grew from 457 mm (18 in) up to 699-762 mm (27.5-30 in) depending on configuration. Every version ran a 16-speed full-powershift transmission, closed-center load-sensing hydraulics, and an independent 1,000-rpm rear PTO with a Category III/IVN hitch. The MT845 followed Caterpillar's own Challenger 65/75/85 rubber-track tractors from the 1990s, before Caterpillar exited agricultural tractors.
Across four generations the core architecture carried over - Mobil-trac oscillating-midwheel undercarriage, powershift transmission, IVN hitch - while AGCO raised horsepower and changed engine platforms at nearly every suffix: Cat C12 to Cat C15, then C15 ACERT for Tier III compliance, then a full switch to AGCO's own 16.8 L engine for the E series. Belt width and operating weight grew in step, letting later machines handle heavier primary tillage and scraper loads. AGCO retired the 845 designation in December 2020, replacing the whole MT800 lineup with the MAN-engined MT851/856/862/867 series, so any MT845 on the market today is a legacy machine no longer in production. That matters in the used and parts trade: buyers need to confirm the exact suffix - blank, B, C, or E - before ordering engine, hydraulic, or undercarriage components, since the four engine platforms are not interchangeable and track, midroller, and drivewheel parts differ by belt width. Demand for good used units and rebuilt undercarriage parts stays active because a rubber belt's flotation and drawbar pull still beat a wheeled 4WD tractor in heavy tillage ground, even years past factory discontinuation.

MT845 fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase, with filter (base MT845, 2001-2007, Cat C12 diesel) | Not documented in the sources reviewed for this series - confirm against the dipstick full mark or the service manual for the specific serial range. For reference only, the standalone Cat C12 diesel (same block family) lists a factory lube-system refill in the 34-36 L (9.0-9.5 US gal) range on Caterpillar's own industrial/on-highway engine data sheets, but that figure is not confirmed for the tractor installation. | SAE 10W-30, API service classification CH-4, per the factory test-certified fill. Cat DEO (Diesel Engine Oil) or an equivalent CH-4/CI-4-rated multigrade is the class of oil called for; shift to a heavier grade such as 15W-40 in hot climates and a lighter cold-weather grade (0W-30/5W-30) for cold starts, per standard Cat viscosity-by-ambient guidance. Note: the later MT845B/MT845C carry a larger Cat C15 engine - a different oil system, not interchangeable with the C12 figures above. The MT845E (2015 onward) switched to a non-Caterpillar AGCO Power engine and is excluded from this chart. |
| Cooling system (radiator, engine jacket, oil coolers) | Not documented for the complete tractor installation in the sources reviewed. Cat's own industrial engine data sheets show a bare-engine jacket capacity in roughly the 23-27 L (24-28 qt) range for this engine family, but the full ag-tractor system - which adds a larger field-duty radiator plus hydraulic and charge-air oil coolers - is not confirmed and is likely larger. Verify against the service manual for the specific serial range. | Cat ELC (Extended Life Coolant) or an equivalent heavy-duty, low-silicate extended-life antifreeze/coolant, mixed 50/50 with water for standard climates; adjust the water/glycol ratio for extreme cold per the coolant supplier's freeze-point chart. |
| Fuel tank | 1154 L (305 US gal) standard tank; 1249 L (330 US gal) with the optional high-capacity tank (330 US gal became the standard fitment on later series). | No. 2-D diesel fuel (ultra-low-sulfur). Blend with No. 1-D diesel in cold weather for cold-flow performance. |
| Hydraulic system, powershift transmission and final drives (common reservoir) | 265 L (70 US gal) total system capacity. Closed-center, pressure/flow-compensated hydraulics at a 200 bar (2900 psi) maximum system pressure - consistent across the Cat-powered MT845 generations tested. | Caterpillar MTO (Multipurpose Tractor Oil) fluid, the factory-specified lubricant for the combined powershift transmission, differential-steering, final-drive and implement-hydraulic circuit on this tractor. A Cat TDTO-spec fluid is the listed equivalent class where MTO is not stocked. |
| Grease points (track roller and idler bearings, pivot pins, 3-point hitch and PTO linkage) | N/A - these are periodic lubrication points, not a fill capacity. Follow the lubrication-interval chart in the operation and maintenance manual. | NLGI 2 multipurpose chassis grease (standard Cat/Challenger multipurpose grease class); the specific branded product name is not confirmed from the sources reviewed. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the MT845 beyond the schedule
Predictive Maintenance & Fluid Analysis
Pull engine oil, transmission/hydraulic oil, and final-drive samples on a fixed hours schedule rather than waiting for symptoms - the closed-center load-sensing hydraulic circuit shares fluid across steering, hitch, and remotes, so contamination shows up everywhere at once. Track a Cat C12/C15 or AGCO Power 16.8L engine's coolant additive concentration and blow-by trend to catch liner or ring wear before a bore glazes. Watch the nitrogen-charged track tensioner pressure gauge; a slow bleed-down before service life is a leak, not normal wear.
Corrective & Common Repairs
Track slippage or premature drive-lug wear traces to worn drivewheel grooves or a misaligned belt - check guide-lug temperature side to side and adjust the idler alignment bolts before replacing rubber. Powershift clutch flare or slow shifts point to transmission filter loading or low system pressure in the shared hydraulic circuit. On C15 ACERT engines, watch for turbo boost leaks and injector balance faults; on E-series AGCO Power engines, check high-pressure fuel system integrity first. Swing-link cap bolts loosen under scraper duty and need routine re-torque.
Overhaul & Rebuild Points
High-hour MT845s wear at the undercarriage first: midrollers, front idlers, and drivewheels lose rubber and need replacement once wear passes factory limits, and the tensioner cylinder and nitrogen accumulator eventually need a full recharge and reseal. Powershift clutch packs and the hydraulic pump/motor set are the next wear point, especially in hard tillage or scraper duty. Engine overhaul timing depends on series - C12 and C15 blocks tolerate long in-frame life, while the AGCO Power 16.8L in the E-series is the newest platform with less high-hour rebuild history.
Seasonal & Environment Servicing
Before spring fieldwork, recheck track tension and alignment after winter storage since temperature swings bleed nitrogen pressure and shrink rubber clearances. In dusty, high-chaff tillage or scraper work, service the primary and secondary air filters more often than the hour chart suggests and keep the radiator and hydraulic cooler screens clear to prevent overheating the closed-center hydraulic system. For cold starts, confirm coolant additive concentration and block-heater function; for wet or muddy ground, inspect midroller seals for leaks that let mud contaminate the rubber-to-steel bond.

MT845 fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| 100-03 | Engine oil pressure sensor circuit voltage above normal range (open circuit or short to a higher voltage), not necessarily an actual low-pressure event. | Corroded or loose sensor connector, chafed sensor wiring, or a failed oil pressure sensor. | Check the sensor connector and harness for damage or corrosion first; confirm true oil pressure with a mechanical gauge before condemning the sensor. |
| 164-02 | Injection actuation pressure signal is erratic or implausible; on the HEUI-type fuel system this is the high-pressure oil circuit that fires the injectors. | Failing injection actuation pressure control valve, a weak actuation oil pump, a leaking injector, or a faulty actuation pressure sensor. | Check actuation (engine) oil level and condition first, then verify actuation pressure with a diagnostic gauge before replacing the control valve or pump. |
| 110-03 | Engine coolant temperature sensor circuit voltage above normal range (open circuit), so the ECM cannot get a valid temperature reading. | Damaged sensor wiring, a corroded connector, or a failed coolant temperature sensor. | Inspect wiring and connector for damage, check sensor resistance against the spec chart, replace the sensor if it is out of range. |
| 111-01 | Coolant level sensor reports level below the normal range. | Low coolant in the system, trapped air at the sensor probe, or a faulty level sensor or its wiring. | Check and top off actual coolant level first; if the code stays with coolant full, inspect the level sensor and its circuit. |
| 168-01 | System (battery) voltage sensed by the ECM is below the normal charging range. | A weak or failing battery, loose or corroded battery cables and grounds, or a charging system fault. | Load-test the batteries, clean and tighten battery and ground connections, then check alternator output before further diagnosis. |
| 190-08 | Engine speed/timing sensor signal has abnormal frequency, pulse width, or period, so the ECM cannot trust the RPM/timing input. | Incorrect sensor air gap, a worn or damaged timing (tone) ring, or a corroded sensor connector. | Check the sensor air gap and connector first, then inspect the tone ring for damaged teeth; replace the sensor only after ruling those out. |
| 262-04 | Shared 5-volt sensor reference supply is reading below normal, which can trigger codes on several sensors at once. | A chafed or shorted wire on the shared 5V circuit, a corroded connector, or an overloaded supply. | Isolate and check each sensor fed from the 5V circuit for a short or ground fault before suspecting the ECM itself. |
| 1-05 | Low current in the cylinder No. 1 injector solenoid circuit; the ECM cannot properly fire that injector, producing a dead cylinder or misfire. | A failed injector solenoid, broken or shorted harness wiring to that cylinder, or (since adjacent cylinders often share a supply wire) a fault on the shared circuit. | Swap the injector with an adjacent cylinder and clear the code: if the fault follows the injector, replace it; if it stays on the same cylinder, trace the harness and connector. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
MT845 attachments & work tools
Three-point hitch (rear linkage)
Category 4N rear three-point hitch with reducer bushings to accept Category 3 pins, catalogued by some sources as Category 5. Offered as a mechanical roller-type hitch (standard) or a controlled-hydraulic hitch (optional). Rated lift is about 8,845 kg (19,500 lb) measured 610 mm (24 in) behind the ball ends per SAE J283, a figure consistent across this model's generations.
PTO (power take-off)
Independent rear PTO with electronic clutch engagement, standard 1000 rpm output on a 44 mm (1-3/4 in) shaft. Claimed PTO output tracks the engine fitted to each generation of this model, in the range of roughly 233-272 kW (310-365 hp).
Drawbar
A rear drawbar is fitted alongside the three-point linkage for towed implements such as grain carts, chisel plows, and disk implements, rated to the same heavy-duty class as the hitch. Specific fixed vs. swinging drawbar variants for this exact model are not broken out in dealer literature; verify current drawbar options with a dealer.
Remote hydraulic valves / implement hydraulics
Closed-center, pressure- and flow-compensated load-sensing hydraulics come standard with four remote valves, with provision for a fifth and sixth. Standard pump flow is about 165 L/min (43.5 gpm), with a high-flow pump option to roughly 220-223 L/min (58-59 gpm) depending on series; each valve's flow rate and timing is set from the cab display, sized to run folding tillage tools, planters, and air-seeder carts.
Undercarriage / track system
Runs the Mobil-Trac rubber-belt undercarriage with oscillating, suspended mid-wheels in place of steel track rollers, giving a smoother ride and lower ground pressure than a rigid crawler. Rubber belts are offered in roughly 762 mm and 914 mm (30 in and 36 in) widths, with undercarriage components shared across this model's C- and E-series siblings in the same frame size.
Ballast / weight system
Front suitcase-style ballast weights and undercarriage weight-support brackets are available to balance the tractor when running heavy mounted or towed implements. These ballast components are shared across the same-frame sibling models in this size class.
Primary work-tool class
Sized for heavy primary tillage (deep rippers, disc rippers), high-capacity field cultivators/finishers, row-crop planters, and air-seeding drills or carts run off the rear linkage, drawbar, and remote valves. This size class is not catalogued by the factory for pull-type earthmoving scraper duty, which is reserved for larger track and articulated siblings in the same family.

MT845 serial number reference
The PIN/serial plate is mounted on the left side of the tractor frame. The first three letters are the prefix that identifies the model and production block; the digits that follow are the running serial number within that block. Because a base model and its next lettered revision can share the same three-letter prefix and differ only by serial block (for example BBP40001-59999 vs BBP6-and-up), always read the full number off the plate rather than the prefix alone, and confirm against dealer records before ordering parts.
| Prefix | Identifies | Notes |
|---|---|---|
| BBP | MT845 first generation (2002-2004) | Serial block BBP40001 through BBP59999, per the factory MT800 Series parts manual (covering MT835/MT845/MT855/MT865, dated October 2005) which lists MT835 as BAM40001-59999, MT845 as BBP40001-59999, MT855 as BCC40001-59999, and MT865 as BDS40001-59999. Built at the point production of the MT-Series Challenger tractors moved from Caterpillar's own line to AGCO under the 2002 Challenger agreement, while still carrying Caterpillar branding. Fitted with a Caterpillar 11.9 L (729 cu in) 6-cylinder turbocharged diesel rated at 380 hp (283 kW) gross, using Caterpillar's electronically controlled unit injection (HEUI) - a pre-ACERT electronic engine, not a mechanically governed one. One farm-equipment database renders the prefix as BPP instead of BBP; treat BBP as the primary reading and confirm against the physical PIN plate for your unit. |
| BBP | MT845B second generation (2005-2008) | Same three-letter prefix as the first generation, but a new serial block starting at BBP6 and up, per the factory MT800B Series parts manual (covering MT835B/MT845B/MT855B/MT865B/MT875B, dated November 2005) which lists MT835B as BAM6-Up and MT845B as BBP6-Up. Engine changed to a Cat C15 ACERT 15.2 L (928 cu in) diesel, rated around 400 gross hp (298 kW) at 2100 rpm, with roughly 335 hp (250 kW) at the PTO. Part of the MT800B Series alongside MT835B/MT855B/MT865B/MT875B, each running its own prefix (BAM/BBP/BCC/BDS/BFT) from its own 6-and-up serial block. |
Frequently asked questions
What engine does the Caterpillar Challenger MT845 use?
It depends on series. The original MT845 (2002-2004) ran a Cat C12 (11.9 L) inline-six at 283 kW (380 hp) gross. The MT845B (2005-2008) moved to a Cat C15 (15.2 L) at 298 kW (400 hp), and the Tier III MT845C (2009-2013) used a Cat C15 ACERT rated at 328 kW (440 hp). The final MT845E (2014-2020) switched entirely to an AGCO Power 16.8 L V12 rated around 336-343 kW (450-460 hp) - confirm the suffix before ordering engine parts.
What is the operating weight of the MT845?
Operating weight varies by series: roughly 18.1 tonnes (about 40,000 lb) on the original MT845, rising to about 19.3-19.5 tonnes (42,600-43,075 lb) on the later B, C, and E versions. Belt width and optional counterweights shift the figure further, so treat any single number as a starting point and verify against the data plate.
What replaced the Caterpillar Challenger MT845?
AGCO carried the MT845 name through the B, C, and E suffixes into 2020, then retired the whole MT800 numbering scheme. In December 2020 it replaced the line with the MAN-engined MT851/856/862/867 track tractors, with the MT851 taking the position the MT845 held in the lineup. Any MT845 on the market today is a legacy machine no longer in production.
What MT845 owners discuss
Does every MT845 use the same engine, or does it change by series?
No — confirm the series off the serial plate before ordering parts or troubleshooting the engine. The original MT845 runs a Cat C12, turbocharged diesel, 11.9 L (729 ci), rated around 283 kW (380 hp). The MT845B (2005-2008) steps up to a Cat 15.2 L (928 ci) turbocharged, air-to-air aftercooled six, gross rating near 298 kW (400 hp) and roughly 250-300 kW (335-402 PTO hp) depending on how it was tested. The MT845C (later build, roughly 2008-2013 — confirm by serial) carries a Cat C15 ACERT, gross rating near 328 kW (440 hp) and about 268 kW (360 PTO hp). Injectors, turbo, and fuel-system parts are not interchangeable across series.
Tractor won't pull like it used to — what's usually behind it on these?
Most reported power loss traces to the fuel system, not the engine block. A plugged fuel tank vent can collapse or crack the tank over time and starve the injection pump, and starved injectors wear faster and lose spray quality. One owner's troubleshooting thread found fuel pressure running around 540-550 kPa (78-80 psi) against a spec closer to 620 kPa (90 psi) — pressure that low reads as soft turbo boost and flat power before anyone suspects the injectors themselves. Before chasing engine work, check the tank vent, fuel filters, and rail pressure against the service manual spec for your series.
What wears out first on the crawler undercarriage?
Mid-roller (bogie) wheel rubber is the most-reported wear item, especially on tractors that see a lot of road transport at speed — the rubber can delaminate from the steel center under sustained heat. Bearings and seals on the same bogie wheels leak and fail alongside it once the rubber starts going. Many owners switch to polyurethane bogie wheels at overhaul since poly sheds heat better and holds up longer under road miles than the OE rubber. Separately, check drive-wheel (sprocket) groove wear — grooves worn or rounded past about 3 mm (1/8 in) let the track slip on the drive wheel even with tension set correctly.
How does the two-track system compare to a four-track design in the field?
Community opinion is mixed and depends on ground conditions rather than a clear reliability verdict. The two-track belt system is generally seen as well-built and gives a smoother ride with strong straight-line drawbar pull. In soft, sloppy ground under load, some operators find a four-track layout turns more cleanly, while the two-track can be tougher to keep clean in heavy mud. It comes down to soil type and how much road transport the tractor does, not one design beating the other outright.
What sensor or electrical faults come up most?
Dealer fault-code listings for this tractor lean heavily on sensor circuits — oil pressure sensor, ground/engine speed sensor, transmission range switch, and parking brake sensor faults are the ones owners mention most. Most trace back to a connector or the sensor itself rather than the component it's monitoring, but the steering and ground-speed sensors feed the differential steering system, so don't guess on those. Have your dealer pull codes with the factory diagnostic tool and verify the fix before returning the tractor to field work.
Any known issues with the hydraulics or brakes?
The closed-center, load-sensing hydraulic system and wet-disc brakes hold up well when fluid and filters are kept on schedule. Reported problems trace almost entirely to neglected maintenance — contaminated hydraulic fluid or stretched filter intervals — rather than a design fault. Because the wet discs also carry steering and parking-brake duty on a crawler, have your dealer verify brake and steering circuit condition on any tractor you're not fully sure has been serviced on schedule.
What should I check before buying a used MT845?
Confirm the exact series (base, B, or C) against the serial plate — engine, horsepower, and parts availability differ enough that the paperwork needs to match the machine. Start it cold and watch exhaust color; white, blue, or black smoke on startup each point to a different problem and none are normal. Inspect mid-roller/bogie wheel rubber for delamination and check for oil weeping at the bogie seals. Check track tension and drive-wheel groove wear, and ask for track-tensioning and undercarriage service history. Crawlers rack up fewer annual hours than wheeled tractors since they often sit parked part of the year, so 5,000-6,000 hours on a 10-15-year-old machine isn't unusual by itself — judge condition, not just the hour meter. Have your dealer pull fault codes and verify brake and steering function before you close the deal.
