Caterpillarmotor grader
Caterpillar 120G
Maintenance schedule, common problems & OEM parts breakdown
The Caterpillar 120G is a mid-frame, direct-drive era motor grader built from roughly 1974 through the early 2000s, spanning serial-number prefixes 11W, 71V, 82V, 87V and 4HD. It runs a Cat 3304 four-cylinder diesel in naturally aspirated or turbocharged (3304T) form depending on serial prefix and power configuration, rated roughly 93-120 kW (125-160 hp) net. Operating weight lands around 11,485 kg (25,320 lb) and varies with blade width, scarifier or ripper fitment and counterweight options. Cat offered the 120G with a power-shift transmission, an extendable moldboard, and a choice of front scarifier, midmount scarifier or rear ripper-scarifier. It anchored Caterpillar's G-series mid-size grader lineup alongside the 12G, 130G and 140G, and Cat phased it out in favor of the 120H family in the mid-1990s as electronic engine and transmission controls took over the line.
Across its long production run the 120G moved through several serial-prefix blocks tied to running changes in engine calibration, brake and hydraulic hardware, and cab or ROPS fitment rather than a clean model-year break; naturally aspirated and turbocharged 3304 engines were both fielded depending on power class and market. None of that touched the core mechanically governed, sleeve-metering fuel system or the oil-bath tandem brakes that define the platform. That mechanical simplicity is exactly why the 120G still matters in the used and parts market: no ECM, no aftertreatment, and a wear-strip and driveline parts supply that has stayed active for decades because so many units are still grading rural roads, mine haul routes and municipal streets. Values hold up because the engine, transmission and tandem hardware are field-rebuildable with common tooling, and worn circle, drawbar and moldboard wear strips are routine, low-cost fixes rather than dealer-only jobs.

120G fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase, with filter (Cat 3304 engine) | Approx. 12-16 L (12.7-17 US qt) at the engine block level; the exact machine-installed refill figure with filter change is not consistently published for this vintage grader across available sources. Fill to the FULL mark on the ENGINE STOPPED side of the dipstick and confirm against the OMM Refill Capacities table for the serial prefix. | Cat Diesel Engine Oil (DEO) or Cat Engine Oil (EO). SAE 10W-30 preferred for ambient -18 C to 40 C (0 F to 104 F); SAE 15W-40 for warmer climates above 0 C (32 F); multigrade blend for cold-start regions below -18 C. API CI-4 or later Cat-approved oil. |
| Cooling system | Not consistently documented for the 120G specifically. Figures found for related/newer grader models span roughly 30-52 L (8-14 US gal) but do not carry over to this machine. Verify against the OMM Refill Capacities table or a dealer for the exact radiator/system volume. | Ethylene-glycol based Cat antifreeze/coolant mixed with water, plus Cat liquid coolant conditioner (supplemental coolant additive). Add 0.5 L (1/2 qt) of conditioner every 100 service hours per the maintenance schedule. Maintain year-round freeze/boil protection; do not run on plain water. |
| Fuel tank | 227 L (60 US gal) | No. 2-D diesel fuel per Cat fuel specification; low-sulfur diesel recommended; use a winter blend or anti-gel additive in cold climates. |
| Transmission and differential (drive train compartment) | Sources disagree, with figures ranging from about 19 L to 68 L (5-18 US gal) depending on source. Treat as unconfirmed for this exact model/serial range - verify against the OMM Refill Capacities table. | Cat Transmission/Drive Train Oil (TDTO). SAE 30 for normal ambient range; SAE 10W for cold-weather start-up; TDTO multigrade where a wider temperature swing is expected. |
| Tandem housings / final drives (each side) | Reported figures vary by source, roughly 19 L per side in some listings, and could not be independently corroborated for the 120G. Verify against the OMM Refill Capacities table or a dealer; capacity is the same for left and right tandem. | Cat TDTO, same viscosity grade used in the transmission/differential fill for the prevailing ambient temperature. |
| Circle drive | Reported figures vary widely across sources, roughly 1.5-19 L, and could not be reliably corroborated for this model. Verify against the OMM Refill Capacities table. | Cat TDTO (per the circle drive lubrication chart), viscosity matched to ambient temperature the same way as the transmission/differential fill. |
| Hydraulic system and tank | Not reliably corroborated for the 120G specifically; publicly available figures conflict. Verify against the OMM Refill Capacities table or a dealer for the exact tank/system volume. | Cat Hydraulic Oil (HYDO). SAE 10W for cold climates, SAE 30 for normal/warm ambient range, per the HYDO viscosity-by-temperature chart. |
| Grease (chassis, spindles, pins - spec only) | Not a sump/refill capacity - grease is applied per fitting per the lubrication interval schedule. | Cat Multipurpose Grease (MPGM), NLGI No. 2 grade; NLGI No. 1 or No. 0 in very cold climates for easier gun dispensing. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the 120G beyond the schedule
Predictive Maintenance & Fluid Analysis
Run oil sampling on the 3304 engine, power-shift transmission and tandem housings at scheduled intervals; sleeve-metering injection pumps and oil-bath tandem brakes show wear as metal content and viscosity shift long before a leak or power loss appears. Track hydraulic oil condition closely since the same HYDO fluid lubricates circle and lift cylinders under constant grading load. Watch coolant conditioner levels between changes to protect wet-sleeve cylinder liners from cavitation erosion, a known weak point on mechanically governed Cat diesels of this era.
Corrective & Common Repairs
Expect sleeve-metering injection pump wear, stuck governor linkage and worn transfer pump valves to show up as hard starting, surging idle or power loss under blade load; isolate pump versus injector faults by cracking lines individually before pulling the pump. Circle, drawbar and moldboard wear strips loosen steering and grading precision and need routine shimming or replacement. Tandem wheel spindle seals and oil-bath brake discs are the other recurring fix, since seepage there contaminates tandem case oil and accelerates bearing wear.
Overhaul & Rebuild Points
Transmission clutch packs take the brunt of repeated blade-load shifting and are usually the first major internal wear item on a hard-worked 120G, needing a rebuild well before the engine needs attention. The 3304's sleeve-metering pump and injectors warrant bench overhaul and recalibration once fuel delivery drifts, since field adjustment alone cannot restore worn plungers or delivery valves. Tandem cases (chains, sprockets, spindle bearings) and the circle drive gear train are the other big-ticket rebuilds tied directly to total grading hours and ground conditions.
Seasonal & Environment Servicing
Dusty, abrasive grading sites chew through precleaner screens, air filters and circle or moldboard wear strips faster than the standard interval assumes, so shorten those checks in high-dust seasons. Cold-weather starts stress the mechanically governed 3304 and its cold-start aid system, so verify coolant conditioner strength and battery condition before winter grading. In wet or muddy seasons, check tandem housing and wheel spindle seals more often, since oil-bath brakes and their seals are the first place standing water and grit find a way in.

120G attachments & work tools
Moldboard (drawbar-circle-moldboard system)
Main grading blade rides in the drawbar-circle assembly. Standard length is 3.66 m (12 ft), with a 4.27 m (14 ft) moldboard offered for wider road coverage. The moldboard is a wear component within the circle rather than a quick-swap tool.
Cutting edges and end bits
Bolt-on replaceable wear edges and end bits fit the moldboard and are common across the 120G and its sibling G/H-series graders of this size class. Edge styles vary for hard-surface finishing versus loose-material moving; select per application, not a fixed factory default.
Moldboard extension
Bolt-on wing extension adds roughly 605 mm (24 in) of coverage to the standard moldboard for faster material spreading and wider-pass road work.
Front blade / front lift group
A front-mounted straight or angled blade bolts to a front lift-group bracket at the nose of the frame. Used for spreading, ditch and slope shaping, tight-corner grading, and light dozing. Requires an auxiliary hydraulic circuit to power the lift cylinder; not standard-fit.
Ripper / scarifier system
Multi-shank parallelogram-style ripper/scarifier, offered in front-mount (light duty, hangs off the front lift group), midmount (better depth control and visibility), or rear-mount (heaviest duty, uses rear-tire weight for penetration) configurations. Rear ripper needs auxiliary rear hydraulics, either factory-fit or added as a kit; shanks and teeth are the wear items and are shared GET across this grader family.
Snow equipment
Class-typical options include U- or V-angle snow blades, V-plows, trip-edge blades, and snow wings. Wings come in mastless (better operator visibility, benches drifted snow on shoulders up to roughly 1.0-1.2 m/40-48 in) and masted (throws deep drifted snow) styles; size and style vary by configuration.
Circle drive protection
The pinion/circle drive assembly on this grader shares a clutch-protected design with its G/H-series siblings, cushioning shock loads to the circle and pinion if the moldboard strikes a fixed obstruction.
Counterweight / push block
Rear-mounted counterweight or push block option rebalances the machine when no ripper is fitted and provides a frame pushing point. Typical factory or dealer-fit option across this size class of grader.
Mounting/coupler method
Work tools mount via bolt-on/pin brackets at the front lift group and rear ripper frame rather than a hydraulic quick-coupler; fitting most auxiliary tools (front blade, ripper, snow wing) requires an available auxiliary hydraulic valve on the machine.

120G serial number reference
The serial/PIN plate on a 120G is riveted to the frame, usually low on the right-hand side near the front axle/articulation area, with the number often duplicated in service records against the engine and transmission serials. Pre-2001 Cat machines like the 120G use the old 8-character format: the first 3 characters are the prefix identifying the production/assembly series, and the remaining digits are the sequential unit number within that series. Match the 3-character prefix to the correct parts or service manual edition before ordering parts, since ranges were revised as production continued.
| Prefix | Identifies | Notes |
|---|---|---|
| 87V | 120G motor grader, Cat 3304 engine | Earliest well-documented 120G production block, dating from the mid-1970s. Reflects running production changes within the block rather than a model change. Powered by the Cat 3304 diesel, rated near 125 hp in this application; some later units in this block show updated ratings up to roughly 140 hp -- verify against the unit's own engine arrangement number. |
| 82V | 120G motor grader, Cat 3304 engine | Runs alongside 87V as a concurrent assembly block. Service literature for this range is issued jointly with 87V, so treat the two as concurrent production series rather than sequential model years. Engine is the Cat 3304 diesel. |
| 11W | 120G motor grader | Later production block, issued together with 82V and 87V in a combined service manual edition. No engine change is documented for this prefix against the 3304-powered earlier blocks. Verify exact build years against the machine's own parts book. |
| 4HD | 120G motor grader, Cat 3304 engine | Final confirmed 120G prefix. Still shown powered by the Cat 3304 diesel in the parts catalog. Represents the last production series before Caterpillar replaced the 120G with the 120H family in the mid-1990s. |
Frequently asked questions
What engine does the Caterpillar 120G motor grader use?
A Caterpillar 3304 four-cylinder diesel, built in naturally aspirated or turbocharged (3304T) form depending on serial prefix and power configuration. Output runs roughly 93-120 kW (125-160 hp) net and varies by configuration. It is a mechanically governed, pre-electronic engine with a sleeve-metering fuel injection system and no ECM or onboard diagnostics.
What is the operating weight of the Caterpillar 120G?
Around 11,485 kg (25,320 lb) in base configuration. Actual weight varies with blade width, scarifier or ripper attachment, and counterweight fitment, so treat that figure as a baseline rather than a fixed number for every unit.
What replaced the Caterpillar 120G motor grader?
Caterpillar replaced the 120G with the 120H family in the mid-1990s, moving the platform to electronic engine and transmission controls. The 120G nameplate itself covers roughly 1974 through the early 2000s of production, spanning several serial-number prefix blocks (11W, 71V, 82V, 87V, 4HD) before it was phased out.
What 120G owners discuss
What's the general reputation of the 120G among people who've actually operated one?
Longtime operators call the 120G a tough, simple grader that's easy to keep running because there's so little to go wrong on a mechanical, pre-electronic machine. The recurring knock is limited lugging power versus the 6-cylinder 12G/140G family - the 4-cylinder 3304 can feel underpowered in a heavy cut or on grade, especially on the lower-output early units. Turbocharged later machines pull noticeably harder than naturally aspirated ones.
My 120G drives fine unloaded but bogs down or acts like the transmission is slipping as soon as I drop the blade into a heavy cut - what's the usual cause?
This is a known complaint on these direct-drive graders, reported in both forward and reverse. It usually points to worn or glazed clutch discs, or a clutch pack that's out of adjustment, not a hydraulic fault. The multiple-disc packs in the direct-drive transmission need periodic mechanical adjustment as the linings wear; left slipping, they overheat and burn the discs, turning a simple adjustment into a teardown. Have your dealer or a qualified grader mechanic check clutch pack adjustment and disc wear before assuming a bigger transmission failure.
What wears out first on a well-used 120G, and what should get the most attention in the maintenance routine?
Two areas come up repeatedly. First, the circle, drawbar, and moldboard wear strips and shims that keep the circle running tight - skipped greasing or ignored side play shows up as sloppy blade control and accelerated wear on the circle gear and pinion. Second, the tandem wheel spindle bearings and oil-bath brake seals; a failed spindle bearing behind the parking-brake drum is called out as a known weak point that makes a mess if it isn't caught before it lets go completely. Routine circle greasing and tandem case oil checks are the cheap insurance most operators recommend.
Is every 120G turbocharged, and how much power does the 3304 actually make in this grader?
No. The 120G was built across several serial ranges (11W, 4HD, 82V, and 87V), and the 3304 diesel isn't identical across all of them - some are naturally aspirated, others carry the turbocharged 3304T. Reported output for the grader varies by configuration/series, roughly the low-90s hp on the naturally aspirated end up to around 120-125+ hp turbocharged. Confirm which version is actually fitted from the engine data plate rather than assuming by grader serial prefix alone.
The 3304 was just rebuilt and it still vibrates above idle, or is hard to start - is that a bad rebuild?
Not necessarily the block. Vibration above idle after a rebuild is usually traced to crank or rod bearing clearance, injector timing or fuel delivery imbalance between cylinders, or worn and loose engine mounts. Hard starting, power loss, or excess smoke on the 3304 is often the sleeve-metering fuel injection pump sticking from dirty or watered fuel; a stuck rack needs freeing and lubrication, not a new pump. In at least one case a freshly rebuilt 120G engine threw a rod because the sump had sand and dirt mixed into the oil - contamination, not a design flaw. Have your dealer check injector timing and mount condition before condemning the rebuild.
What electrical problems come up on the 120G, and does it throw any fault codes?
No - it's a mechanically governed, pre-electronic machine, so there are no sensors or ECM codes to chase. What electrical complaints do surface are ordinary for any older 24-volt machine: corroded battery cable and ground connections, and tired starter or alternator output. Most cranking complaints trace back to battery and ground condition rather than the starter itself. One real safety point on cold starts: never spray ether into the intake if a glow plug element could still be hot, since igniting fuel on a hot element can cause a backfire or intake damage. Have your dealer confirm the correct cold-start sequence for your machine before relying on ether.
What should I check before buying a used 120G?
Walk the frame first for cracks, weld repairs, or patch plates before looking at anything else. Sight down the machine at the articulation joint - if the engine compartment sits lower than the cab, the hinge is bent or loose. Check the circle and moldboard for side play and worn strips, and look under the machine and around the circle drive housing and all cylinders for leaks. Pull the engine and grader serial numbers off the data plates to confirm the actual configuration (naturally aspirated vs turbocharged, standard vs optional equipment) matches what's being represented, and ask for maintenance records. Have a dealer or independent grader mechanic verify clutch pack condition and hydraulic pressure on a test run before you commit to buying.
