Caterpillar MT855
Maintenance schedule, common problems & OEM parts breakdown
The Caterpillar-lineage MT855 is a high-horsepower rubber-belt (Mobil-Trac) crawler tractor built for row-crop and heavy tillage work, sold under the AGCO Challenger brand after AGCO bought Caterpillar's agricultural Challenger line in 2002. The base MT855 (2002-2004) runs a Caterpillar 14.6 L (893 cu in) non-ACERT inline-six diesel rated around 335 kW (450 hp) gross and 279 kW (374 hp) at the PTO, controlled by an ADEM engine ECM read through the tractor's own Tractor Management Center display and Cat ET diagnostics. Operating weight sits close to 18,597 kg (41,000 lb), varying with ballast and options. The badge carried on through later series on different engines: the MT855B (2005-2008) moved to a Cat C15 ACERT rated near 343 kW (460 hp) gross, the MT855C (2009-2013) to an uprated C15 ACERT near 354 kW (475 hp), and the MT855E (2014-2020) dropped the Cat engine for an AGCO Power 16.8 L V12. Configurations across the run include a standard, or from the B-series on steerable, rear 3-point hitch, an independent 1000 rpm rear PTO, and closed-center load-sensing hydraulics flowing 165 L/min (43.5 GPM) standard, up to 223 L/min (59 GPM) optional.
Across the run, AGCO widened the undercarriage and lowered ride height for a flatter center of gravity: base MT855 track belts measure 457 mm (18 in) with 475 mm (18.7 in) of ground clearance, the B-series steps up to 699 mm (27.5 in) belts with clearance down to 366 mm (14.4 in), and the C-series widens again to 762 mm (30 in) belts. The B-series also added a factory-optional steerable 3-point hitch for towed implements on side-hill ground. Emissions rules pushed the powertrain from non-ACERT to Tier III ACERT on the B and C-series, then off the Cat block entirely on the E-series, which runs an AGCO Power V12 with no Cat parts commonality. That split matters in today's used and parts market: the 2002-2013 Cat-engine generation (base, B, C) remains the practical value zone, since its engine, filters, and ECM diagnostics still track back through Caterpillar's own parts and service network, while E-series units need a separate AGCO Power supply chain. Undercarriage wear items, mid-roller and idler bearings, track belts, and drive sprockets, are the highest-turnover parts category on aging examples still working ground today.

MT855 fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase (with filter) — Caterpillar C16 diesel, 14.6 L inline-six | Not published in the aggregator spec sheets and brochures reviewed for this tractor's specific oil-pan configuration. Do not assume an on-highway truck fill volume applies — the tractor sump differs. Verify exact quarts/liters with the operator's manual or dealer. | Cat DEO (Diesel Engine Oil) 15W-40 for normal ambient range; Cat DEO 10W-30 for cold starts below roughly 0°C (32°F). API CI-4 performance level or better. |
| Cooling system | Not documented in the sources reviewed for this model. | Cat ELC (Extended Life Coolant), pre-mixed 50/50 ethylene-glycol/water, per standard Caterpillar diesel-engine practice for this engine family. |
| Fuel tank | 1,154–1,159 L (305 US gal) standard tank; 1,249–1,254 L (330 US gal) with the optional auxiliary tank. | No. 2-D ultra-low-sulfur diesel fuel. |
| Transmission, hydraulics, steering, differential and final drives — combined single system/reservoir | Approximately 265 L (70 US gal) total system fill. This machine shares one common reservoir and one rear sight gauge across the transmission, hydraulic, steering, differential and final-drive circuits rather than separate sumps per component — there is no standalone hydraulic-tank-only figure or per-side final-drive figure to report. | Cat TDTO (Transmission/Drive Train Oil), SAE 10W as the base grade for this combined powertrain/hydraulic circuit; heavier grades (30, 50) or the TDTO-TMS multigrade are used per ambient temperature, with a cold-weather 0W-graded TDTO for sub-freezing starts. System runs closed-center, pressure-flow-compensated hydraulics rated at 2,900 psi (200 bar), standard pump flow 43.5 GPM (164.6–164.7 L/min), optional high-flow pump 59 GPM (223–224.2 L/min). |
| Grease — external lubrication points (undercarriage pivots, drawbar, PTO shaft, hitch) | Spec only, not applicable. | NLGI 2 multipurpose Caterpillar-spec grease (moly-fortified) is standard practice for this era of Cat/Challenger track tractor external lube points. The exact commercial product name is not confirmed from a source tied specifically to this model — verify with dealer. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the MT855 beyond the schedule
Predictive Maintenance & Fluid Analysis
Run S·O·S oil sampling on the Cat inline-six at every oil change, and sample the transmission/hydraulic reservoir separately to catch mid-roller and front idler bearing wear before it shows up as play in the track frame. Watch the ADEM ECM fault log through Cat ET for derate events triggered by lugging hard in low gears, an early flag for fuel, air, or cooling restriction. Check track tension pressure on the Tractor Management Center display daily; a cold-morning false trip on the sensor is common, worth a recheck.
Corrective & Common Repairs
Most SCV and remote hydraulic complaints trace back to ECM or valve-bank wiring, not the pump; check connectors and harness routing before pulling the closed-center pump. Mid-roller and front idler bearing replacement is the most common undercarriage repair, with field life running roughly 2,000-4,500 hours depending on terrain and duty cycle. Track belt tension adjustment and drive sprocket tooth wear follow close behind. Engine derate under heavy lugging in low gears usually resolves with fuel, air filter, or cooling system service rather than injector work.
Overhaul & Rebuild Points
Major overhaul work centers on the Cat inline-six top end (injectors, turbocharger, cylinder head) and the 16-speed powershift clutch packs. Rebuild the closed-center load-sensing hydraulic pump and valve bank as a set rather than piecemeal once flow response degrades. Undercarriage overhaul means replacing mid-rollers, front idlers, and track frame bushings together, since mixed wear rates on rebuilt versus original components accelerate uneven track wear. Inspect the rear 3-point hitch lift-arm pins and bushings and the independent PTO clutch and shaft splines at the same interval.
Seasonal & Environment Servicing
Cold starts need ether or block-heater assist on the Cat inline-six, and cold mornings are when the track-tension sensor tends to false-trip; verify accumulator pressure before assuming a fault. Clear packed mud, crop residue, and snow from the mid-rollers and track frame regularly since buildup accelerates bearing wear and throws off tension readings. In dusty harvest or tillage conditions, service the engine air filter and cab fresh-air filter more often than the standard interval, and clean the radiator and hydraulic oil cooler cores to prevent heat-soak derates during heavy fieldwork.

MT855 fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| CID 100 - FMI 03/04 (Engine Oil Pressure Sensor) | ECM sees the oil pressure sensor signal outside its normal range - FMI 03 is voltage above normal (open circuit or short to a powered wire), FMI 04 is voltage below normal (short to ground). | Corroded or loose sensor connector, chafed harness shorted to ground or to a hot circuit, or a failed sensor. | Check the sensor connector and wiring for an open or short before condemning the sensor; verify actual oil pressure with a mechanical gauge if the engine is also showing low-pressure symptoms. |
| CID 110 - FMI 03/04 (Engine Coolant Temperature Sensor) | Coolant temperature sensor circuit reads outside normal range - FMI 03 signal shorted high, FMI 04 signal shorted low. | Damaged sensor wiring, corroded connector pins, or a failed sensor element. | Inspect the sensor connector and harness for damage or corrosion, test sensor resistance against spec, and replace the sensor if wiring checks out good. |
| CID 111 - FMI 02/03/04 (Engine Coolant Level) | Coolant level circuit is erratic or reads a low-coolant condition - FMI 02 is an erratic/invalid signal, FMI 03/04 are high/low voltage faults in the level sensor circuit. | Actual low coolant, a fouled or failed level probe in the surge tank, or a wiring fault to the probe. | Check coolant level and top off if low, inspect the surge tank probe and connector, then retest before replacing the probe. |
| CID 168 (Electrical System / Battery Voltage) | ECM detects system voltage outside the expected charging range, or an erratic/intermittent voltage signal. | Weak or failing battery, loose or corroded battery/ground cables, or a charging system (alternator/regulator) fault. | Load-test the batteries, clean and tighten all battery and ground connections, then check charging voltage at the batteries with the engine running. |
| CID 91 - FMI 08 (Throttle Position Sensor) | Throttle position signal from the pedal/lever sensor is abnormal or out of the expected frequency/range. | Worn or misadjusted throttle sensor, damaged wiring, or a connector fault at the pedal or hand-throttle assembly. | Inspect and reseat the throttle sensor connector, check sensor calibration/adjustment, and retest before replacing the sensor. |
| CID 190 - FMI 08 (Engine Speed / Timing Sensor) | Engine speed or timing sensor signal has an abnormal frequency, meaning the ECM cannot reliably read crank/cam speed. | Damaged or incorrectly gapped speed/timing sensor, metal debris on the sensor tip, or a wiring/connector fault. | Check sensor air gap and mounting, inspect for debris and wiring damage, and clear the code after correcting before returning to service. |
| CID 174 - FMI 03/04 (Fuel Temperature Sensor) | Fuel temperature sensor circuit reads outside normal range, high or low voltage. | Damaged wiring or connector at the sensor, or a failed sensor element. | Inspect wiring and connector for damage or corrosion, verify sensor resistance, and replace the sensor if the circuit tests good. |
| CID 41/262/263 (Sensor Supply Voltage - 8V/5V) | One of the ECM's regulated sensor supply voltages (used to power several engine sensors) is reading above or below normal. | A shorted sensor or harness pulling down the shared supply rail, or a fault inside the ECM's supply circuit. | Disconnect sensors fed by the affected supply one at a time to isolate a shorted sensor or harness segment before suspecting the ECM. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
MT855 attachments & work tools
Rear 3-point hitch / mounted implements
Rear hitch is Category III/IV-narrow (some listings also note a plain Category IV option), rated at roughly 19,500 lbs (8,845 kg) lift capacity. A quick-hitch coupler is offered so mounted tillage and seeding tools can be hooked up without manual pin alignment.
Rear PTO
Independent rear PTO running at 1000 rpm on a large-diameter (1-3/4 in) spline shaft, rated at 374 hp (279 kW) with tested output up to about 452 hp (337 kW). PTO-driven implements are a secondary work-tool path behind drawbar and 3-point pulling on a machine this size.
Rear remote hydraulics (SCV circuit)
Closed-center, pressure/flow-compensated (load-sensing) hydraulic system at about 2,900 psi (200 bar). Standard pump flow is around 43.5 gpm (165 L/min) with an optional high-flow pump up to about 59 gpm (223 L/min), feeding 4 to 6 rear remote (SCV) outlets. This is the circuit that powers folding tillage tools, air-seeder/cart drives, and other hydraulically actuated trailed implements; exact valve count and flow are configuration-dependent.
Drawbar / heavy pull-type tillage tools
Fitted with a heavy rigid rear drawbar; tested drawbar power reaches about 347 hp (259 kW), with a peak pull rating around 42,800 lb (19.4 t). This is the primary interface for large primary-tillage tools (inline/disc rippers, chisel plows) and grain carts in this horsepower class.
Undercarriage / rubber track (belt) options
Rubber belt (Mobil-Trac) undercarriage. Factory track shoe width options include 46, 70, 76 and 91 cm (18, 27.5, 30 and 36 in). Track gauge (tread width) is field-adjustable, roughly 228-325 cm (90-128 in), to match row-crop spacings.
Special-application scraper drawbar (construction/earthmoving)
A recognized aftermarket/factory-style conversion swaps the standard ag drawbar hanger for a heavy scraper drawbar, letting the tractor pull single, tandem, or triple pan scrapers for earthmoving work. This reflects the model's continued role in pull-type earthmoving equipment alongside its row-crop and tillage use, a carryover from its Caterpillar-era construction market ties.

MT855 serial number reference
The PIN/serial plate is mounted on the left side of the tractor's main frame rail. Read the full string in order: the letters immediately after the model number are the version/build-range code, and the digits that follow are the running serial count within that code, so match both the letters and the digit range against the parts or service manual's stated effective-serial break points to confirm the exact build level. This tractor is a Challenger-brand machine built by AGCO rather than Caterpillar itself, though its earlier build generations carry a Caterpillar-family engine, so the PIN format follows AGCO's own scheme.

| BCC | MT855, Series I build and the mid-2000s running update sold as the "B" build | Base MT855 crawler tractor. Numeric serial run starts near 20001 for the first model year, 30001 the next year, 40001 the year after, then climbs through the 50000s. The same three-character code carries forward once the mid-decade running update takes hold, with serials moving into the 60000s; that update is a running change, not a new prefix. Original build carries a Caterpillar 14.6 L (890 ci) inline six-cylinder diesel rated 335 kW (450 hp) gross; the updated build steps up to a 15.2 L (928 ci) Caterpillar six rated 343 kW (460 hp) gross. PIN plate sits on the left side of the tractor frame rail. |
| not confirmed - read PIN plate | MT855C, later production run (sources vary: roughly 2009-2013, one source spans 2008-2016) | No public listing ties a specific three-character code to this update. Fitted with a larger Caterpillar inline six-cylinder diesel, 15.1 L (921 ci), rated 354 kW (475 hp) gross. PIN plate location is unchanged, left side of the frame rail. Read the plate directly or confirm the exact prefix with a dealer before ordering parts against a serial break. |
| F.. (CE-spec; exact middle characters unconfirmed) | MT855E, roughly 2014-2020, European (CE) specification | One factory publications listing for the CE-spec MT845E/MT855E/MT865E/MT875E family gives an effective code starting with F and a running serial beginning near 1001; the model-specific middle characters for this size are not spelled out in that listing, so treat as confirm-with-dealer. This update drops the Caterpillar engine in favor of an AGCO Power 16.8 L (1025 ci) V12 diesel rated 365 kW (490 hp) gross, paired with a Caterpillar-built powershift transmission. Verify the exact three-character code against the machine's own PIN plate; the North American (non-CE) build may carry a different code. |
Frequently asked questions
What engine powers the Caterpillar MT855?
The base MT855 (2002-2004) uses a Caterpillar 14.6 L (893 cu in) non-ACERT inline-six diesel rated at roughly 335 kW (450 hp) gross and 279 kW (374 hp) at the PTO, controlled by an ADEM engine ECM. Later series carried the badge on different engines: the B-series moved to a Cat C15 ACERT block, the C-series to an uprated C15 ACERT, and the E-series dropped the Cat engine entirely for an AGCO Power 16.8 L V12.
What is the MT855's operating weight?
Operating weight for the base MT855 is commonly listed at about 18,597 kg (41,000 lb), though figures as high as roughly 19,900 kg (43,920 lb) appear depending on ballast, track width, and options. Treat the figure as a range rather than a fixed number; actual weight varies by configuration and series.
What replaced the Caterpillar MT855?
Within its own line the base MT855 was followed by the MT855B (2005-2008) and MT855C (2009-2013), both still built around Cat C15 ACERT power. The real platform break came with the MT855E (2014-2020), which replaced the Caterpillar engine entirely with an AGCO Power 16.8 L V12, ending Cat parts commonality on this model.
What MT855 owners discuss
What do long-time owners and mechanics say about the MT855's powertrain reliability?
Community consensus rates the powertrain as one of the stronger points of the machine. The inline-six diesel and the 16-speed powershift transmission are generally described as solid, with strong low-end pulling torque that owners rate highly for heavy tillage and seeding work. The recurring complaint is that the engine derates once it's lugged too far down in the lower gears; dropping one more gear at that point often doesn't recover much power, so operators are told to match gear selection to load rather than lug it. Fuel economy is generally rated favorably for the horsepower class. Exact behavior varies by series and duty cycle.
What hydraulic-system behaviors and complaints come up most often?
The closed-center, pressure-flow-compensated hydraulic system runs 43.5 GPM (about 165 L/min) standard, with a higher-flow (roughly 59 GPM / 223 L/min) pump optional — enough for planters, air-seeders, and grain-cart duty. The recurring gripe in owner reports is that the selective hydraulic remotes can act up over time; a slow or unresponsive remote is usually traced to wiring or a connector fault between the ECM and the remote valve rather than the pump itself. Confirm actual pump flow and remote count for the specific serial/build rather than assuming a spec.
What undercarriage wear patterns should owners expect on the Mobil-trac system?
Mid-roller (bogie) wheel bearings and front idler bearings/seals are the components that wear out first and get replaced most. Reported life varies widely — some owners see idler bearing trouble as early as roughly 2,000 hours, others ran a machine to 4,100-4,500 hours before a bearing let go — so treat any single figure as a range driven by soil type, ground speed, and side-hill work rather than a fixed service life. Track guide blocks and lugs crack or work loose when a track partially walks off the drive wheel on sloped ground; re-torquing or replacing guide hardware is routine maintenance on hilly operations, not a sign of a defective machine. Idler-housing oil should be checked and changed on a regular interval — true of all rubber-tracked machines, not unique to this one.
Is there a field trick to check track tension and alignment without a shop gauge?
Run the tractor about 8-10 km (5-6 miles) at full travel speed, then check the guide-block temperature on both sides of each track. The two sides should read within roughly 14°C (25°F) of each other; a bigger spread points to a dragging bearing or uneven tension rather than a track that simply needs adjusting. Tension itself is set by pumping grease into the track adjuster valve at the front idler grease fitting, and released by loosening the same fitting. The track adjuster holds hydraulic pressure in the circuit, so have your dealer verify the correct release procedure before loosening it.
Do engine quirks differ by MT855 generation?
Yes, and it matters which one you own. The original MT855 (2002-2004) ran a Cat C15/C16-class inline six from the early AGCO-Challenger transition; the B (2005-2008) and C (2008-2013) generations moved to Cat C15 ACERT. On C15 ACERT engines generally, worn injectors show up as rough idle, misfire, extra smoke, and softer fuel economy, and a suspected turbo failure is frequently actually a fuel or charge-air leak underneath it — pressure-test the induction and fuel systems before condemning the turbo. The later E generation (2014-2020) switched to an AGCO Power V12 entirely; it's newer and far less discussed in owner circles, so don't carry C15/ACERT-era quirks over to it. Have your dealer verify which engine and emissions configuration is actually in a given serial number before diagnosing or ordering parts.
What electrical or sensor issues come up in service discussions?
Two patterns recur. First, the selective control valves for the hydraulic remotes route through the tractor's ECM, and when a remote won't respond the fault is often in that ECM-to-valve wiring or a connector rather than the valve itself. Second, some owners in cold climates report a track-tension warning triggering in very cold weather — roughly -29°C (-20°F) and below — even when the tracks are mechanically fine, pointing to a temperature-affected sensor reading rather than a real tension problem. Confirm actual track sag before making any mechanical adjustment off a cold-weather code, and have your dealer verify the fault before condemning the sensor.
What should a buyer check when looking at a used MT855?
Walk the tracks and mid-rollers/idlers for play and uneven wear — outer edge versus inner edge wear tells you about alignment and side-slope history. Check idler-housing oil condition, then run the tractor and compare guide-block temperatures side to side. Cycle every hydraulic remote under load to confirm response, and pay attention to how the powershift clutch releases; some machines feel grabby right after a fluid service, but persistent harshness deserves a closer look. Most important, confirm exactly which generation and engine is fitted — the original C15/C16-class engine, the C15 ACERT B/C-series, or the later AGCO Power V12 E-series — since parts, fluid specs, and known quirks differ by generation. Given the hours these machines typically carry, have your dealer verify undercarriage and hydraulic condition before final purchase.
