Caterpillar 120M

Maintenance schedule, common problems & OEM parts breakdown

The Caterpillar 120M is a mid-size motor grader built for road maintenance, site grading, and general earthmoving. It runs a Cat C6.6 ACERT 6-cylinder, 6.6-liter diesel rated 103-136 kW (138-182 hp) net depending on VHP, VHP Plus, or AWD configuration, and meets EPA Tier 3 / EU Stage IIIA emissions. Operating weight spans roughly 14,466 kg (31,891 lb) in base trim to about 20,271 kg (44,690 lb) in a fully equipped AWD configuration. The 120M is the M-series successor to the long-running 120K/120H/120G grader line, offered as a standard rear-wheel-steer machine and as an all-wheel-drive (AWD) variant, with a standard 3.7 m (12 ft) moldboard or an optional 4.3 m (14 ft) moldboard.

The 120M's main shift from its K-series predecessor was ACERT emissions technology on the C6.6 engine, paired with a redesigned cab, joystick controls, and easier-access service points such as top-loading drawbar wear inserts and simplified circle lube access. Caterpillar later replaced the 120M with the 120M2, which stepped up to the larger C7.1 ACERT engine and higher-tier emissions hardware, moving the platform into a heavier class. That leaves the 120M as the last grader in this size bracket before the displacement jump, which keeps it in steady demand on the used and parts market: a simpler emissions system than later Stage IV/Tier 4 Final machines, broad parts commonality across the C6.6 industrial engine family, and a layout familiar to shops and operators who came up on K-series graders.

Servicing the 120M beyond the schedule

Predictive Maintenance & Fluid Analysis

Run S·O·S oil sampling on the C6.6 ACERT engine every 250 hours to catch bearing and injector wear early. Pull parallel samples from the transmission, tandem cases, hydraulic tank, and (on AWD units) the wheel gear group; metal in an AWD hub sample usually flags planetary wear before it strands the machine. Track circle drive oil condition at each 2000-hour change; rising iron content there traces back to skipped daily pinion greasing more often than the oil itself.

Corrective & Common Repairs

Circle drive pinion teeth and the blade circle itself take the most abuse on a 120M; skipped daily greasing wears the pinion and circle ring fast, and both show up as slop in the moldboard. Drawbar wear inserts and moldboard slide rail wear strips need regular shimming or replacement to stop chatter and uneven cuts. AWD-equipped units add wheel hub and planetary seal leaks as recurring repair items. Steering cylinder and linkage wear shows up as drift or hunting under load.

Overhaul & Rebuild Points

Tandem case and transmission oil changes at 1000 hours are the early warning line for gear and bearing wear inside the tandem housings; metal-laden oil there signals a coming tandem overhaul. Circle drive gear and, on AWD machines, the wheel gear group get fresh oil at 2000 hours, the usual point to inspect the circle ring gear and guide shoes for wear. Hydraulic pump and cylinder reseal work typically lines up with the 4000-hour full hydraulic oil change, alongside the C6.6 ACERT valve lash check.

Seasonal & Environment Servicing

Cold climates need block heaters and correct-viscosity oil for the C6.6 ACERT before start-up, plus closer coolant freeze-point checks on the Cat ELC fill. Dusty or high-debris sites shorten cab HVAC evaporator and heater coil cleaning well below the standard 2000-hour mark. Wet or humid regions need more frequent fuel tank water-and-sediment draining and fuel filter checks to protect the ACERT fuel system. Winter grading work adds tire chain and ballast inspection to the daily walk-around.

120M fault codes & troubleshooting

CodeMeaningLikely causeWhat to do
E192 (3) — Steering System MalfunctionImplement ECM lost a valid position signal from the steering cylinder position sensors while steering was commanded; treated as an immediate safe-shutdown event on M-series graders.Worn or loose spherical bearings at the steering cylinder pivots let the front wheels flutter and confuse the position sensors; also caused by a faulty steering cylinder position sensor, damaged connector, or a fault in the electro-hydraulic steering valve actuator.Stop the machine safely per the operator manual procedure, inspect steering cylinder pivot bearings for play, check position sensor connectors for corrosion or damage, then pull logged codes on the Implement ECM with Cat ET.
597-14 — Implement Hydraulic Pump / Secondary Steering Pump, Special InstructionSecondary (standby) steering pump circuit reports pressure above roughly 7500 kPa (1000 psi) while the pump is expected to be idle, or fails its automatic startup self-test.Drifted or faulty implement pump pressure sensor, sticking relief valve, or a wiring fault on the secondary steering pump circuit; often shows up alongside a steering system malfunction code.Run the secondary steering pump self-test at key-on, compare sensed pressure to a shop gauge, inspect the pressure sensor and its wiring to the Implement ECM, and correct before returning the machine to service since this affects backup steering.
127-3 — Transmission Oil Pressure Sensor, Voltage Above NormalTransmission ECM sees the transmission oil pressure sensor signal above the valid range, consistent with an open circuit or a short to supply voltage rather than an actual pressure reading.Damaged or failed pressure sensor, chafed harness shorted to a power circuit, or a corroded/loose connector at the sensor.Inspect the sensor connector and wiring for a short to battery voltage, verify sensor supply and signal with Cat ET on the Transmission ECM, and replace the sensor if wiring checks out good.
41-4 — 8 Volt DC Sensor Supply, Voltage Below NormalThe 8V sensor reference supply from the ECM is reading below the valid range, indicating the supply is loaded down or shorted.A shorted sensor or chafed harness on a circuit fed by the 8V supply, water intrusion at a connector, or an internal ECM supply fault.Disconnect sensors fed by the 8V supply one at a time to isolate the short, inspect connectors for corrosion or moisture, and confirm supply voltage recovers once the faulty branch is isolated using Cat ET.
2252-3 — Articulation Angle Sensor #2, Voltage Above NormalImplement ECM sees the secondary articulation angle sensor signal above the valid range.Sensor wiring shorted to a power circuit, a failed articulation sensor, or a loose/corroded connector at the frame pivot.Inspect the articulation sensor and harness routing at the frame hinge point, check connector pins for damage, and verify sensor operation with Cat ET.
168-3 / 168-4 — Electrical System Voltage, Above/Below NormalMain machine electrical system voltage sensed by the ECM is outside the normal charging range; FMI 3 is high voltage, FMI 4 is low voltage.Weak, sulfated, or failed battery; corroded or loose battery terminals and ground straps; faulty alternator or voltage regulator.Check battery state of charge and terminal condition, measure charging voltage at idle and high idle (typically in the 13.8-14.4V range with the engine running), and inspect alternator output and ground connections.
110-0 / 110-3 — Engine Coolant Temperature SensorFMI 0 indicates the sensor reading is valid but the coolant temperature itself is above the normal operating range (a real overheat condition); FMI 3 indicates the sensor circuit voltage is above normal, pointing to a wiring or sensor fault rather than actual heat.For an actual high-temperature event: low coolant, plugged radiator core, fan drive or fan clutch fault. For a circuit fault: damaged coolant temperature sensor or chafed/shorted wiring.Check coolant level and radiator core condition first, confirm fan operation, then check the sensor connector and wiring if the code points to a circuit fault, and verify with Cat ET on the engine ECM.
100-0 / 100-3 — Engine Oil Pressure SensorFMI 0 indicates a valid reading of an actual low oil pressure condition; FMI 3 indicates the sensor circuit is shorted high or open, a wiring/sensor fault rather than a true pressure problem.Real low pressure: low or degraded engine oil, worn oil pump or bearings. Circuit fault: failed oil pressure sensor or damaged wiring/connector.Check oil level and condition and verify actual pressure with a mechanical gauge before condemning the sensor, then inspect the sensor connector and wiring, confirming with Cat ET on the engine ECM.

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

120M attachments & work tools

Front moldboard / blade

Standard moldboard is 3.7 m (12 ft); an optional 4.3 m (14 ft) moldboard is offered for wider road coverage. A bolt-on moldboard extension adds up to 605 mm (24 in) of additional coverage on one side.

Front lift group

Optional front-mounted, hydraulically actuated lift group bolts to the nose of the machine and gives a hydraulic quick-coupling point for front-mounted tools. It accepts straight/front blades, V-plows and reversible plows, and a light-duty front scarifier.

Scarifiers

Front scarifier hooks to the front lift group for light-duty work, breaking up compacted material, asphalt and rocky subgrade ahead of the moldboard. A mid-mount scarifier (behind the front axle) gives better cut-depth control, improved forward visibility, and can fracture harder material.

Rear ripper/scarifier

Hydraulic rear-mounted ripper/scarifier attaches behind the tandem, putting rear-tire weight over the shanks for maximum penetration in hardened ground. Shanks and teeth are interchangeable between ripping and scarifying duty.

Snow removal tools

Snow package includes straight and flexible U/V blades for plowing, pushing, casting or carrying snow, plus V-plows for pioneering through deep drifts. Snow wings come in mastless (40-48 in bench height, for shoulders/ramps) and masted (60 in bench height with below-grade ditch-cleaning reach) versions.

Push block

Push block mounts to the machine's nose plate. It serves as a counterweight to balance a rear-mounted ripper and doubles as a push point when the grader is used to push other equipment.

Tow hitch

Optional rear tow hitch allows the grader to pull trailed implements or equipment behind the machine.

Guarding and protection package

Standard bottom guard covers the transmission and filters; an upgraded steel guard option is available for demanding, debris-heavy applications. A front axle cylinder guard option protects the cylinders, hoses and fittings on rough or rocky terrain.

Drawbar-circle-moldboard assembly

Standard equipment: tubular A-frame drawbar and a box-sectioned circle with hardened circle teeth. Top-adjust wear strips let shims and strips be replaced through access plates without dropping the circle, cutting moldboard/circle adjustment time.

Cutting edges and end bits

Moldboard cutting edges are offered in flat or curved profiles, with straight or serrated (bolt-on) options, sized to match the 12 ft or 14 ft moldboard. Through-hardened end bits protect the moldboard corners from abrasive wear; thickness/width are matched to the moldboard selected.

All-wheel-drive (AWD) configuration

Factory AWD arrangement drives the front wheels hydraulically for extra traction in mud, sand, gravel or snow and improves side-slope stability. AWD machines run 113-309 mm (4.4-12.2 in) wider than the standard 2WD arrangement, varies by configuration.

120M serial number reference

The PIN/serial plate is riveted to the machine frame. Reported locations vary by source: the front frame rail near the steering gear/cab window, or the frame just forward of the moldboard lift cylinder support (left or right side varies by build) — check the frame rail under the cab if the plate is not immediately visible. On machines built after 2001 the plate carries a 17-character PIN; the 3-letter serial prefix plus 5-digit sequence number form the last 8 characters (for example B9N00156). That prefix ties the machine to a specific model/configuration build for parts and service lookup.

Frequently asked questions

What engine does the Caterpillar 120M motor grader use?

The 120M runs a Cat C6.6 ACERT, a 6-cylinder, 6.6-liter diesel rated 103-136 kW (138-182 hp) net, depending on VHP, VHP Plus, or AWD configuration. It meets EPA Tier 3 / EU Stage IIIA emissions. The 120M2 that followed switched to the larger C7.1 ACERT, a different engine family.

What is the operating weight of the Caterpillar 120M?

Base operating weight is about 14,466 kg (31,891 lb). Fully configured with AWD, a larger moldboard, and attachments, weight climbs to roughly 20,271 kg (44,690 lb). Exact figure varies by moldboard size, AWD option, and attachment fitment.

What replaced the Caterpillar 120M motor grader?

Caterpillar replaced the 120M with the 120M2 and 120M2 AWD. The 120M2 keeps the same size class but moves to the larger Cat C7.1 ACERT engine, a step up from the 120M's C6.6 ACERT. The 120M itself succeeded the 120K/120H/120G line.

What 120M owners discuss

What powertrain behavior do owners and mechanics flag on the 120M?
The 120M (Series 1) runs the Cat C6.6 ACERT engine with HEUI-style fuel injection. Mechanics note the injectors wear over the long haul: rough idle, a step down in power, and worse fuel economy on high-hour units usually trace back to injector leakage rather than the ECM. On the powershift transmission, the recurring service mistake is using the wrong fluid - engine oil or an overly slippery gear oil in place of Cat TDTO (TO-4) starves the clutch discs of friction and shows up as slipping or harsh, delayed shifts. Correct fluid discipline avoids most of the powershift complaints owners report.
What hydraulic quirks show up as the machine ages?
Circle, moldboard, wheel-lean, and steering cylinders all seep with age as seals and hoses harden. Because these cylinders run in a dirty jobsite environment, contamination getting past a nicked rod seal is the usual root cause of scored bores and internal leaks - not the cylinder itself failing outright. Owners are told to keep hydraulic fluid on the change schedule and inspect hose clamps and chafe points regularly rather than wait for a visible leak to show up.
What wear pattern is typical for the circle, drawbar, and moldboard system?
A motor grader has no track undercarriage, so the equivalent wear system is the circle/drawbar/moldboard assembly. The forged-steel circle rides on nylon composite wear inserts between the drawbar and circle and between the support shoes and circle, with brass wear strips under the moldboard - all sacrificial and meant to be shimmed or swapped through top-adjust access plates rather than replacing the circle itself. Uneven wear across the circle face is the classic sign of a machine that has been run out of alignment or under-greased; daily greasing (or the optional auto-lube circle saver) matters a lot here because a dry circle chews up the pinion and circle teeth quickly.
Are there engine quirks specific to the 120M's C6.6 ACERT versus the later 120M2's C7.1?
Yes, keep them separate. The 120M (B9N/B9C/R9A prefixes) uses the C6.6 ACERT engine, and factory ratings on this platform span both a Tier 3-equivalent build with no exhaust aftertreatment and a Tier 4 Interim-equivalent build carrying a diesel particulate filter and oxidation catalyst, depending on region and build date - check the engine emissions label and serial rather than assume which one a given unit has. General C6.6 ACERT complaints (HEUI injector wear, occasional overheating, gasket weeps) apply to the 120M's engine family. None of that should be confused with the 120M2 successor's C7.1 ACERT (M9C/M9H prefixes), which is a different engine generation with its own service history.
What electrical or sensor problems come up most in the field?
M-series graders, the 120M included, run fully electronic joystick controls - the joysticks sit on circuit boards feeding the machine's ECMs rather than working mechanical linkages. One documented 120M no-start case involved a jumping tachometer and a fuel primer that would not engage with the key on; the fault was eventually traced to a loose or corroded wiring-harness connection in the engine compartment, not the ECM or injection pump. Before condemning an ECM or a sensor on a hard-start or erratic-gauge complaint, wiggle-test the harness connectors first - that is where these faults usually live.
Is there a safety-relevant failure point worth knowing about?
Steering response on M-series graders is entirely electronic (steer-by-wire), and the steering control actuators on this platform were revised several times over the years; only the later-generation actuators are considered reliable long-term. Combined with wheel-lean and steering cylinders that can develop internal leaks from hydraulic contamination, a machine can develop steering drift or sluggish response that is easy to dismiss as normal wear. Because loss of predictable steering response is a safety issue on a machine this size, have your dealer verify the actuator generation, current ECM software level, and steering/wheel-lean cylinder condition before returning the grader to service.
What should a buyer check before purchasing a used 120M?
Start with maintenance and service records - a consistent history matters more than hours alone. Have a Cat-equipped technician pull a Product Status Report through Cat ET to confirm all ECMs are on current software, since the M-series had a heavy run of control-system updates over the years. Walk the frame for cracks or fishplate repairs, check the circle face for uneven wear (a sign of misalignment or neglected greasing), check the moldboard cutting edge and wear strips for straightness, and start the engine cold - watch for smoke, listen for knock, and check for coolant, oil, and hydraulic weeps. Bring a qualified inspector along if unsure; circle, steering-actuator, and electronics repairs on this class of grader are not cheap.
