Caterpillar MTC855
Maintenance schedule, common problems & OEM parts breakdown
The Caterpillar MTC855 is a rubber-tracked row-crop tractor in the Challenger MT800 series, a Caterpillar-engineered platform built for high-horsepower tillage, planting, and drawbar work. Across its production life it ran a Caterpillar inline-6 diesel in the 14.6-15.2 liter range, rated from roughly 450 to 475 gross horsepower (335-354 kW) depending on series, with operating weight around 18,600 kg (41,000 lb) before ballast and attachments. Caterpillar licensed the Challenger name, livery, and engines to AGCO in 2002, and the MT855 designation carried forward as AGCO-built, Cat-powered machinery through the MT855, MT855B, and MT855C revisions into the mid-2010s. It shipped with a 16-speed powershift transmission, an adjustable Mobil-trac track gauge, and configurations built around PTO, drawbar, and three-point hitch work for row-crop and heavy tillage operations.
Across the MT855 generations, gross horsepower climbed from roughly 450 to 460 to 475 hp and engine displacement grew from 14.6 to 15.2 liters, later moving to a Cat C15-family ACERT engine with updated emissions hardware, while the Mobil-trac rubber-belt undercarriage and 16-speed powershift architecture stayed consistent. Later D and E-generation Challenger crawlers eventually dropped the Caterpillar-sourced engine in favor of AGCO Power units, closing out the direct Cat-engine lineage that the MTC855 belongs to. In the used and parts market, these Cat-engine Challengers still draw steady demand from row-crop and tillage operations that value the Caterpillar diesel's reliability and the Mobil-trac ride, which keeps a active aftermarket alive for undercarriage wear items such as rubber belts, midrollers, idlers, and reaction-arm bearings even as factory support for the platform ages.

MTC855 fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase (with filter) - Cat C15 turbocharged diesel, 15.1-15.2 L displacement | Not published in accessible spec sheets for this exact machine - verify against the dealer OMM before servicing | Cat DEO or DEO-ULS diesel engine oil. Viscosity selected by ambient temperature per the Cat multigrade chart, typically 15W-40 in warm climates stepping down to 10W-30 or 0W-40/5W-40 synthetic blends for cold-start regions |
| Cooling system | Not documented in available sources for this model - confirm with dealer OMM | Cat ELC (Extended Life Coolant) or an equivalent heavy-duty extended-life antifreeze meeting Cat's cooling system water/glycol specification |
| Fuel tank | Approx. 1154-1155 L (305 US gal) standard tank; extended tank approx. 1249 L (330 US gal) where fitted | No. 2-D diesel fuel (ULSD on later emission-tier builds); fuel grade shifts to No. 1-D or a winter blend in cold climates per the operator's manual |
| Transmission / powertrain compartment (16-speed full powershift) | Separate fill volume not confirmed in publicly available documentation for this machine - verify against dealer OMM | Cat MTO (Multipurpose Tractor Oil), the factory-specified fluid for Challenger track-tractor power-shift transmission, wet-brake, and drivetrain compartments. MTO is not interchangeable with standard TO-4/TO-4M Cat TDTO; it is formulated for wet-brake compatibility and cold-weather flow down to about -25 degC (-13 degF) |
| Final drives (left and right) | No separate published fill volume found; on this track-tractor layout the final drives commonly draw from the shared transmission/hydraulic reservoir rather than an isolated sump - confirm configuration in the OMM | Cat MTO, matching the shared transmission/hydraulic fill |
| Hydraulic system and tank | Approx. 265 L (70 US gal) total system oil volume per factory spec data; standard pump flow is about 165 L/min (43.5 gpm), with a high-flow option near 223 L/min (59 gpm) - single-sourced figure, confirm against the OMM | Cat MTO (Multipurpose Tractor Oil), shared with the transmission/final-drive circuit on this machine |
| Axles / differentials | Not applicable - this is a rubber-track (Mobil-trac) undercarriage with final drives rather than differential axles | n/a |
| Grease (chassis, pivots, idlers) | Spec only - no reservoir capacity | Cat Multipurpose Grease, NLGI #2 lithium-complex type, or an equivalent EP multipurpose grease meeting Cat's grease specification |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the MTC855 beyond the schedule
Predictive Maintenance & Fluid Analysis
Track oil analysis for the Cat diesel and 16-speed powershift transmission at every scheduled interval to catch bearing and clutch wear before it becomes a failure. Monitor Mobil-trac belt tension against its nitrogen-accumulator and hydraulic-cylinder setpoint; drifting readings often predict a reaction-arm bearing problem before the belt ever visibly slips. Sample coolant on the Cat DEO/ELC-spec cooling system to catch liner or gasket seepage early. Log fuel filter restriction trends, since injector wear on this engine shows up as gradual power loss before a hard fault sets.
Corrective & Common Repairs
The MTC855's most common failure is the reaction-arm bearing, which lets the track frame twist and the belt lose tension, typically in the 4,000-6,000 hour range on machines used for heavy pulling. Idler swing-arm bearing wear shows up as uneven guide-block wear on one side of the belt. Track tensioner cylinders develop grease leaks that keep the system from holding proper tension. Inspect drive wheel rubber for rounded or shallow grooves, a sign of chronic belt slippage.
Overhaul & Rebuild Points
Plan an undercarriage rebuild around the 4,000-6,000 hour mark: reaction-arm bearing, idler bearings, and midroller seals tend to wear out together on machines with heavy drawbar use. The Cat diesel supports an inframe overhaul once oil analysis shows rising blow-by or bearing wear metals. The 16-speed powershift's clutch packs are the other major wear item; pull and inspect them if shift quality degrades or oil analysis shows friction material. Rebuild the track tensioning cylinder once it can no longer hold pressure.
Seasonal & Environment Servicing
Use block heaters to cold-start the Cat diesel and confirm coolant is mixed to the ELC-spec freeze point before winter fieldwork; rubber belts stiffen in low temperatures, so recheck track tension after the first cold-weather hours. In dusty tillage conditions, service the air cleaner and cab filter more often than the standard interval calls for. Clear chaff and debris from the radiator and charge-air cooler fins during harvest to prevent overheating. Drain the fuel/water separator more often in humid or wet-season work.

MTC855 fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| 100-3 | Engine oil pressure sensor circuit voltage above normal range | Sensor signal wire shorted to a higher-voltage circuit, or open sensor circuit | Inspect sensor connector and wiring for damage or corrosion before replacing the oil pressure sensor |
| 100-4 | Engine oil pressure sensor circuit voltage below normal range, often paired with a low oil pressure warning | Sensor signal wire shorted to ground, failed sensor, or genuinely low system oil pressure | Confirm actual oil pressure with a mechanical gauge before replacing the sensor; check oil level and pump condition |
| 110-3 | Engine coolant temperature sensor circuit voltage above normal range | Open sensor circuit or damaged wiring/connector at the coolant temperature sensor | Inspect wiring and connector, test sensor resistance against spec, replace sensor if out of range |
| 190-8 | Engine speed signal abnormal frequency, pulse width, or period from the primary speed/timing sensor | Incorrect sensor air gap, damaged sensor, or damaged timing ring | Check and reset the sensor air gap first; replace the speed sensor only if the gap is correct and signal is still faulty |
| 168-4 | Battery potential / ECM power input voltage below normal | Weak or discharged battery, corroded ground strap, or fault in ECM power supply wiring | Test battery voltage and charging system output, then inspect and clean ECM power and ground connections |
| 41-4 | 8 volt DC sensor supply voltage below normal | A sensor sharing the 8V reference circuit is internally shorted to ground | Disconnect sensors on the shared 8V circuit one at a time to isolate the shorted component, then repair wiring or replace the sensor |
| 1176-3 | Turbocharger/intake boost pressure sensor circuit voltage above normal | Open sensor circuit or failed boost pressure sensor | Inspect sensor wiring and connector, test sensor output against spec, replace if faulty |
| 157-3 | Fuel injector metering rail pressure sensor circuit voltage above normal | Open or damaged wiring at the fuel rail pressure sensor, or failed sensor | Check sensor wiring and connector, verify actual rail pressure with diagnostic software, replace sensor if signal remains out of range |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
MTC855 attachments & work tools
Rear three-point hitch
Optional Category IV-N rear hitch rated around 19,500 lb (8,845 kg) lift capacity. On this class of Challenger track tractor it can be ordered as an exclusive steerable design that ties into the tractor's steering to help wide mounted implements track through headland turns.
Rear PTO (power take-off)
Optional independent rear PTO running at 1000 rpm on a 1-3/4 in (44 mm) 6-spline output shaft, used to drive PTO-input implements such as mounted tillage or seeding tools. Standard driveline shielding applies at the PTO stub.
Drawbar / towed-implement hitch
Multiple drawbar choices for towed tillage tools, carts and wagons: a fixed drawbar, a wide-swinging roller drawbar, or a hydraulically controlled drawbar, each rated near 11,000 lb (5,000 kg) vertical load. Drawbar position is adjustable to match implement hitch height.
Auxiliary hydraulic remotes (SCVs)
Closed-center, load-sensing hydraulic system feeds remote valves that power hydraulically actuated implements (folding toolbars, air-seeder or planter drives, etc.). Four remotes are standard with roughly 43.5 gpm (166 L/min) flow, expandable to six remotes with an optional higher-output pump near 59 gpm (223 L/min); flow is proportioned across active circuits so multiple functions run smoothly together.
Ballast / weight packages
Front-frame and chassis ballast weight kits are offered to balance the tractor against mounted or towed implement loads and to tune drawbar pull and track/wheel loading for the job. Ballast is sized per operation rather than fixed to one implement type.
In-cab hitch/PTO/hydraulics management
Where the 3-point hitch, PTO and remote valve options are fitted, an integrated cab control and display center groups their controls with the transmission and throttle, giving the operator single-point management of attached work tools and roading lockout for transport.
Work-tool scope for this class
This is a high-horsepower rubber-track row-crop/tillage tractor, not an excavator-style carrier, so its 'attachments' are farm implements coupled via the 3-point hitch, drawbar and PTO/hydraulic remotes rather than buckets, forks or hydraulic breakers. Typical mounted/towed tools in this size class include large disc/chisel tillage implements, rippers, planters, air-seeder carts and grain/tillage wagons sized for 400+ hp draft loads.

MTC855 serial number reference
The PIN/serial tag on MTC855-family Challenger crawler tractors is riveted to the left side of the main tractor frame, near the front of the machine. The prefix is the first three letters of the stamped serial (e.g. BCC), immediately followed by a numeric sequence run - read the three letters right before the trailing digits to identify the range.
| Prefix | Identifies | Notes |
|---|---|---|
| BCC | MTC855 base series (Challenger MT855), 2002-2004 model years | MTC855 is Caterpillar's parts/model-code designation for the AGCO-built Challenger MT855 crawler tractor, which used Cat-supplied power train components after AGCO took over the agricultural Challenger line in 2002. Published parts-catalog serial split for this base generation runs from serial 40001 up (catalog print covered 40001-59999). Engine is a 14.6L Caterpillar inline-6 diesel rated about 450 hp gross. Built at the Jackson, Minnesota plant. |
| BCC | MTC855B (Challenger MT855B), 2005-2008 model years | Same BCC prefix continues into the B-series update per the contemporary parts catalog, which shows the range starting over near serial 6 and up for the B revision. Engine steps up to a 15.2L Cat C15 ACERT turbocharged/aftercooled inline-6, about 460 hp gross and 385 hp PTO. Same Jackson, Minnesota plant. |
| BCC | MTC855C (Challenger MT855C), 2009-2013 model years (confirm with dealer) | A Caterpillar-branded workshop manual ties the MT855 to the BCC serial prefix without stating which sub-generation it covers, so continuation of BCC into the C-series is plausible but not confirmed against an official parts-book serial split for this specific range. Engine is again a Cat C15 ACERT inline-6 (about 15.1-15.2L), with gross rating rising to about 475 hp. Confirm the exact prefix break with a dealer before relying on it for parts lookup. |
Frequently asked questions
What engine does the Caterpillar MTC855 use?
A Caterpillar inline-6 turbocharged diesel, roughly 14.6-15.2 liters depending on series, rated from about 450 to 475 gross horsepower (335-354 kW). Exact displacement and rating vary by series (base MT855, MT855B, MT855C) - check the serial plate to confirm which engine your machine carries.
What is the operating weight of the MTC855?
Approximately 18,600 kg (41,000 lb) base weight. Actual weight varies with track gauge width, ballast, and any hitch or PTO-mounted implements.
What replaced the Caterpillar MTC855?
Within the same model line it was followed by the MT855B and then the MT855C. Later AGCO Challenger crawler generations moved off Caterpillar-sourced engines entirely in favor of AGCO Power units, ending the direct Cat-engine lineage this machine belongs to.
What MTC855 owners discuss
Which engine does the MTC855 run, and does it change across the build?
Two distinct engines carry the 855 badge. Early-build machines (roughly 2002-2004) run a Caterpillar 14.6L inline-six rated 336 kW (450 hp) gross, paired with a 16-speed full-powershift transmission. Later C-series machines (roughly 2009-2013) step up to a 15.1L inline-six rated 354 kW (475 hp) gross with a claimed 287 kW (385 hp) PTO rating, same 16-speed powershift. Confirm serial and build year before assuming displacement, injection components, or output specs; the two generations are not interchangeable.
How does the C15-family engine feel to operators doing heavy tillage or ripping work?
Owners call the 855's engine strong and dependable for general tillage, but it sits mid-pack in the lineup. For wide toolbars or deep ripping that pulls into the 373 kW (500 hp) class, experienced users steer buyers toward the larger-displacement siblings instead, noting the 855 disappoints once load climbs past its comfortable working range. Within its intended duty cycle it is regarded as solid, long-running power.
What undercarriage wear pattern shows up most on these track tractors?
Front or outer idler wheel and bearing wear is the complaint that comes up most, sometimes even at modest hours. The usual root cause is road transport with a misaligned belt rather than a parts defect. Fitting a poly idler wheel and checking or changing idler oil on a set interval, more often if the machine sees a lot of road travel, cuts the recurrence sharply. Rubber belts remain the single costliest wear item and the one buyers can inspect visually before purchase. Have your dealer verify idler bearing play and belt alignment before returning the machine to heavy use.
Are there known quirks with the hydraulic system?
The platform runs a closed-center, pressure and flow compensated hydraulic system, factory pump pressure in roughly the 200-228 bar (2900-3300 psi) range depending on configuration, with a 21-24 bar (300-350 psi) differential expected at the remote couplers. A recurring field complaint on this platform is cooling fan speed dropping when another remote circuit is engaged at the same time. That traces most often to a pump compensator that has backed down from spec pressure, or to remotes left dialed to full flow instead of matched to the actual circuit's needs, which also wastes fuel and adds heat. Have your dealer verify compensator pressure and remote flow settings with a gauge before chasing parts.
Do scraper or construction-spec and ag-spec 855 tractors behave differently?
Yes. Units set up for towing scrapers carry protection software that derates the engine hard during sustained low-speed, high-load work, which owners find frustrating on grading jobs. The ag-spec version does not carry this limiter. On some larger siblings in the range a dealer reflash can remove or adjust the low-speed protection; whether that option exists on a given 855 depends on the control software installed, so treat it as a machine-specific question rather than a given.
What fails at high hours on a well-used 855?
Long-term owners running machines past 10,000 hours report the recurring wear items are mid-wheel, hub, and bearing wear on the undercarriage rather than the engine or transmission. Total repair spend over that life can stay a small fraction of the machine's value when maintained on schedule. The most common complaint overall is comfort, not reliability: a cab that runs noisy and lets in dust over time.
What should a buyer check before purchasing a used MTC855?
Walk the tracks first; belt wear is the biggest-ticket item and the easiest to see. Check idler and mid-wheel bearings for play, confirm the hour meter reads accurately, and ask for maintenance records. A documented oil and filter history on the engine, transmission, and idler bearings says more than a low number on the meter. Run the engine, transmission, and every hydraulic remote under load together and watch for the fan-speed or pressure symptoms owners describe on this platform. Confirm which engine generation the unit carries, 14.6L or 15.1L, since output and parts differ, and if it is a scraper or construction-spec unit ask whether the low-speed protection software is active. Have your dealer verify compression, transmission clutch condition, and undercarriage measurements with proper test equipment before final purchase.
