Caterpillar 322

Maintenance schedule, common problems & OEM parts breakdown

The Caterpillar 322 is a medium crawler excavator from Caterpillar's original 300-series lineup, built roughly through the early-to-mid 1990s ahead of the 322B's 1996 introduction. Serial-number prefixes 7WL and 8CL cover base 322 production; a long-undercarriage sibling, the 322L (serial prefix 9RL), ran the same 3116 engine alongside it for jobs needing extra stability or reach. Power comes from the Caterpillar 3116, a turbocharged inline six-cylinder diesel of about 6.6 L (403 cu in) displacement, rated around 114 kW (153 hp) net at 1950 rpm. Operating weight sits in the roughly 24.9 t class (about 54,800-55,000 lb), varying with undercarriage length, boom/stick configuration, and attachment. The machine is fully mechanical: a governor-controlled fuel rack meters fuel through sleeve-metering unit injectors, and hydraulics run open-center off engine-driven pumps, with no electronic control module anywhere in the fuel or hydraulic system.

Caterpillar carried this platform forward from the 322 to the 322B in 1996 and then to the 322C, and each step moved the machine toward electronic engine control. The 322B generation shifted onto the 3126, Caterpillar's first electronically controlled mid-range diesel, replacing the 322's purely mechanical fuel system with hydraulically actuated electronic unit injection; the 322C pushed further into electronic engine management. That makes this original 322 the last fully mechanical machine in the family line before electronics arrived. In today's used and parts market, that mechanical simplicity is the draw: no ECM or engine wiring harness to fail, a fuel system a field mechanic can diagnose and rebuild with hand tools, and a low buy-in price that makes it a practical budget excavator for basic digging, trenching, and grading work where sensor-driven diagnostics are not a priority.

322 fluids & capacities

SystemCapacityRecommended fluid
Engine crankcase (with filter)approx. 18-22 L (19-23 US qt) for the Cat 3116 turbocharged diesel fitted to this machine; confirm the exact fill against the dipstick range for your serial prefixCat DEO (Diesel Engine Oil) meeting Cat's engine oil spec. SAE 15W-40 covers most ambient ranges; drop to SAE 10W-30 in sustained cold below 0C (32F), SAE 30 or SAE 40 in consistently hot climates.
Cooling systemapprox. 24-28 L (6.3-7.4 US gal), typical for this engine and frame size - varies by configuration, confirm against the OMM for your serial prefixCat ELC (Extended Life Coolant) or Cat DEAC (Diesel Engine Antifreeze/Coolant), mixed 1:1 with water for about -37C (-34F) freeze protection. Do not mix ELC and DEAC formulations in the same system.
Fuel tankapprox. 370-400 L (98-106 US gal); reported figures vary by source and configuration - confirm on the tank rating plate or fuel gauge for your machineDiesel fuel meeting Cat's No. 1-D/No. 2-D specification (ASTM D975 equivalent). Use a winterized low-temperature blend in cold climates.
Hydraulic system totalapprox. 200-230 L (53-61 US gal) system total - varies by configuration and boom/stick setup, confirm against the OMMCat HYDO hydraulic oil (or equivalent anti-wear hydraulic fluid meeting Cat's hydraulic oil spec). Use HYDO 10W in cold climates, HYDO 30 or a multigrade HYDO in temperate to warm climates.
Hydraulic tankapprox. 115-130 L (30-34 US gal) tank-only fill - varies by configuration, confirm against the OMMSame Cat HYDO hydraulic oil used for the system total; check sight gauge with implement retracted and machine on level ground.
Final drive (each)approx. 9-11 L (2.4-2.9 US gal) per sideCat TDTO (Transmission/Drivetrain Oil) meeting the TO-4 spec, straight-grade SAE 30 typical with multigrade TDTO acceptable across a wider temperature range. Do not substitute extreme-pressure gear oil - EP additives attack the seals.
Swing driveapprox. 8-9 L (2.1-2.4 US gal)Same Cat TDTO TO-4 spec oil as the final drives; select the viscosity grade by ambient temperature per Cat's lubricant viscosity chart.
Grease (spec only)not a bulk-refill system - applied at greased pin and bushing points per the lubrication scheduleCat Multipurpose Grease (moly-fortified) or Cat Extreme Application (XA) grease, NLGI grade 2, for standard-temperature service.

Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Caterpillar 322 maintenance schedule

Service intervalTasks
Every 50 h
  • Check engine oil level on the dipstick before starting; top off with Cat DEO (Diesel Engine Oil) at the correct viscosity grade for ambient temperature.
  • Check coolant level in the radiator and overflow bottle; inspect the water pump and hose fittings for seepage.
  • Drain water and sediment from the primary fuel filter/water separator bowl before it reaches the sleeve-metering unit injectors.
  • Grease all boom, stick, and bucket linkage pins and the bucket cylinder pivot points.
  • Walk the undercarriage; check track tension, sprocket and idler wear, and loose track shoe hardware.
  • Check the hydraulic tank sight gauge for oil level and inspect cylinder rod seals for external leakage.
Every 250 h
  • Change engine oil and filter using Cat DEO at the correct grade for the season.
  • Replace the fuel filter element and clean the primary fuel strainer/water separator bowl.
  • Check and adjust the fan and alternator belt tension.
  • Pull engine oil and hydraulic oil samples for lab analysis; the 3116 carries no onboard oil-condition sensors.
  • Lubricate the swing bearing and all remaining boom/stick grease points on the full lubrication chart.
  • Check battery electrolyte level and clean terminals; these are conventional flooded batteries, not maintenance-free.
Every 500 h
  • Change the hydraulic return and pilot filters.
  • Check swing drive and final drive gear oil levels; top off with Cat TDTO.
  • Inspect and adjust track sag to the specified undercarriage tension.
  • Clean or replace the air cleaner primary and secondary elements as needed.
  • Inspect the turbocharger on 3116T/3116TA units for shaft play, oil leakage, and boost line condition.
  • Check the fuel rack and governor linkage for free movement and wear.
Every 1,000 h
  • Change swing drive gear oil with Cat TDTO.
  • Change hydraulic pilot and case-drain filters; clean the tank strainer screen.
  • Check final drive gear oil level; top off with Cat TDTO.
  • Pressure-test the cooling system and radiator cap; inspect hoses and clamps for age cracking.
  • Measure boom, stick, and bucket pin-bushing clearances and record wear trends.
  • Inspect track and carrier rollers and idlers for seal leakage; replace any weeping units.
Every 2,000 h
  • Change final drive gear oil with Cat TDTO.
  • Change hydraulic tank oil system-wide with Cat HYDO; clean or replace the tank breather.
  • Check and adjust engine valve lash on the 3116 cylinder head.
  • Change engine coolant, or test conventional coolant condition and additive concentration.
  • Check swing bearing bolt torque and ring-gear backlash.
  • Inspect engine mounts, exhaust manifold, and turbocharger mounting hardware for cracking or looseness.
Every 4,000 h
  • Send the fuel rack, governor, and sleeve-metering unit injectors out for calibration and pop-pressure/spray-pattern testing; mechanical fuel systems drift gradually before they fail outright.
  • Inspect the engine top end (valve train, head gasket, turbocharger core) for rebuild need.
  • Evaluate main hydraulic pump and swing/travel motor performance; rebuild if cycle times have slowed or oil analysis shows metal.
  • Assess undercarriage wear percentage and plan track chain, sprocket, and idler replacement.
  • Reseal boom, stick, and bucket cylinders if rod drift or external leakage has developed.
Every 6,000 h
  • Plan a full engine overhaul evaluation (liners, bearings, turbocharger core) based on oil-analysis and compression trends.
  • Rebuild or replace worn swing drive and final drive gear sets if backlash or oil analysis indicates wear.
  • Rebuild the main hydraulic pump and control valve if internal leakage or slow response has progressed.
  • Replace undercarriage components (track chains, sprockets, idlers, rollers) that have reached wear limits.
  • Re-torque and inspect structural pin bosses, boom foot, and counterweight mounting hardware.

Servicing the 322 beyond the schedule

Predictive Maintenance & Fluid Analysis

Run oil-sample analysis on a fixed cycle since the 3116 on this era of 322 has no onboard diagnostics or fault codes. Pull engine oil, hydraulic oil, swing drive, and final drive gear oil samples at each service interval and track wear-metal and soot trends rather than waiting for symptoms. The sleeve-metering unit injectors and turbocharger show wear through rising iron and aluminum counts well before power loss or smoke appear. Watch coolant condition closely too; a conventional cooling system scales and corrodes without regular additive top-off.

Corrective & Common Repairs

Expect boom, stick, and bucket pin-bushing wear before major hydraulic failures on a machine this age. Check clearances regularly and re-bush before play cracks the bosses. On the fuel side, rough idle or hard starting on the 3116 usually traces to fuel rack linkage wear, sleeve or injector wear, or governor drift, not electronics, since this engine carries no ECM to fault-code the problem. Track sag, sprocket wear, and weeping roller seals round out the recurring undercarriage repairs.

Overhaul & Rebuild Points

At major hour milestones, pull the fuel rack, governor, and unit injectors for shop calibration and pop-pressure testing; a mechanical fuel system drifts out of tolerance gradually and costs power and fuel economy long before it fails outright. The 3116 top end and turbocharger core are the next common rebuild point. On the hydraulic side, swing and travel motor wear shows up as slow cycle times and drift; rebuild before contaminated oil spreads metal through the whole hydraulic system.

Seasonal & Environment Servicing

Cold starts are the main seasonal risk on a mechanically governed diesel with no electronic cold-start assist beyond basic ether or intake-air preheat aids. Run winter-grade engine oil and a cold-weather fuel blend to keep the sleeve-metering injectors from gumming or gelling. In hot, dusty ground conditions, check the radiator and oil cooler cores often since this conventional cooling system depends on clean fins and correct coolant mix. Grease undercarriage and linkage pins more often in mud or abrasive dirt to protect bushings and swing bearing seals.

322 fault codes & troubleshooting

CodeMeaningLikely causeWhat to do
E2Monitor shows E2 when engine oil pressure drops below the normal running rangeLow engine oil level, failing oil pressure sending unit, worn oil pump, or a clogged suction screenStop the engine at once, check oil level and look for leaks before restart, then test the sending unit if level is correct
E3Monitor shows E3 when engine coolant (water) temperature exceeds the normal rangeLow coolant level, blocked radiator core, failed thermostat, or a slipping/damaged fan driveReduce load and let the engine idle down to cool; do not shut off while hot, then check coolant level and radiator once safe
E4Monitor shows E4 when hydraulic tank oil temperature exceeds the normal rangeLow hydraulic fluid, a clogged or dirty oil cooler, or extended relief-valve operation from overloading the systemEase off hydraulic work and let the machine idle to cool, then check fluid level and clean the cooler fins
E5Monitor shows E5 when system/battery voltage runs outside the normal charging rangeFailing alternator, loose or corroded battery terminals/ground strap, or a bad voltage regulatorCheck alternator belt tension and output, then inspect battery cables and terminals for corrosion
E6Monitor shows E6 when it loses the charging-circuit signal from the alternatorBroken or disconnected wire at the alternator charge-indicator terminal, or a blown fuse in that circuitCheck continuity of the alternator charge-indicator wiring and connector, replace the fuse if blown

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

322 attachments & work tools

Buckets

Factory general-duty (GD) bucket on the 322 runs roughly 1.1-1.4 m3 (1.4-1.8 yd3), about 1.2-1.35 m (47-53 in) wide, pin-on mount matched to the stick and bucket-linkage pins. Heavy-duty and rock buckets for this ~21-25 t class trim width down to roughly 0.6-0.9 m (24-36 in) for better breakout force and penetration in fragmented rock or hardpan. Exact capacity shifts with boom/stick combination and wear-plate spec, so check against your specific linkage before ordering.

Hydraulic hammers

The 322 sits in the same carrier-weight bracket as the mid-size class of hammers built for roughly 17,000-32,000 kg (37,000-70,000 lb) carriers, with tool/moil diameter around 125-140 mm. Typical breaker circuit demand for this class runs about 160-180 kg/cm2 (2,270-2,560 psi) working pressure and 120-180 L/min (32-48 gpm) flow — match the hammer to whatever the auxiliary circuit is actually set to deliver rather than the carrier's main pump rating.

Quick couplers

A pin-grabber style hydraulic quick coupler is offered for the 322, sharing the same coupler family fitted to the next size class up, using roughly 90 mm bucket pins on about 515 mm (20-1/4 in) pin center-to-center spacing. As-built the 322 uses a fixed pin-on bucket linkage; the hydraulic coupler is an add-on that lets the machine swap buckets, hammers, thumbs, and grapples without pulling pins by hand.

Thumbs/grapples

Hydraulic and mechanical thumb kits sized for the 18-25 t excavator class fit the 322's stick and bucket linkage, usually pivoting off the same bucket pin so the thumb tracks with the bucket through its full range. Demolition and sorting grapples built around the same 90 mm pin class are also compatible, mounted either pin-on directly to the stick/linkage or through the same hydraulic coupler used for buckets and hammers.

Rippers

Single-shank rippers sized for this stick class mount pin-on and use a hardened one-piece shank, suited to breaking hardpan, frozen ground, or lightly fragmented rock ahead of the bucket. A machine this size is limited to lighter ripping duty — heavy rock ripping calls for a larger-class carrier.

Hydraulic-kit notes

The 322 carries a factory auxiliary hydraulic line and valve group, including a flow-control valve and a selector valve, separate from the boom/stick/bucket circuit. This is sized to run one-way tools such as compactors and vibratory plates, or two-way tools such as hammers and shears. Size any hammer or shear to this auxiliary circuit's actual flow and pressure setting, verified at the valve, rather than assuming a high-flow circuit is fitted.

322 serial number reference

The PIN plate is a riveted metal tag near the base of the cab structure, usually on the right side near the cab door step; the serial is also cross-stamped into the main frame steel nearby as a backup. Read the first three characters as the prefix - it ties the machine to a specific model/configuration and production block - and the digits after it as the sequential build number within that block. This machine PIN is separate from the 3116 engine's own serial plate on the engine block; don't mix the two when ordering parts.

PrefixIdentifies
7WL322 (standard undercarriage); same prefix block also documented as covering the 322 L long-undercarriage build
8CL322 (standard undercarriage); same prefix block also covers the 322 L long-undercarriage build

Frequently asked questions

What engine does the Caterpillar 322 excavator have?

This legacy 1990s Cat 322 runs the Caterpillar 3116, a turbocharged inline six-cylinder diesel of about 6.6 L (403 cu in) displacement, rated around 114 kW (153 hp) net at 1950 rpm. It is fully mechanical: a governor-controlled fuel rack meters fuel through sleeve-metering unit injectors, with no electronic control module. This is not the unrelated modern India-built 'Cat 322,' which uses a different C3.6 engine.

What is the operating weight of the Caterpillar 322?

Operating weight for this legacy 322 runs approximately 24.9 t (about 54,800-55,000 lb), depending on undercarriage length, boom/stick configuration, and attachments. The long-undercarriage 322L sibling, built on the same 3116 engine, sits at a very similar weight. Confirm against the specific machine's build plate rather than a single published figure.

What replaced the Caterpillar 322?

The 322 was succeeded by the 322B, introduced around 1996, which moved the platform onto the 3126, Caterpillar's first electronically controlled mid-range diesel. The 322C followed with further electronic engine management. That lineage is the direct successor path from this mechanical, ECM-free 322.

What 322 owners discuss

What do owners and mechanics say about cold-starting a 3116-powered 322?
Consensus is to let the glow plug relay finish its full preheat cycle before cranking rather than jumping straight to starting fluid — spraying ether onto glow plugs that are still hot is called out repeatedly as a bad habit that can cause an intake-side flash. For machines that still labor to start once temperatures drop, the practical fixes owners mention are a block/coolant heater and, on machines worked in cold climates, an upgraded or second battery bank rather than leaning on ether as the default starting aid. Because a starting-fluid flashback is a personal-injury risk, have your dealer verify the glow plug relay timing and starting-aid setup rather than guessing at it.
What fuel-system quirks come up most on the mechanically governed 3116 in the 322?
Because this engine runs a mechanical governor and injection pump with no engine electronics, most fuel complaints trace back to the transfer pump and its plumbing rather than the injection pump itself: a tired transfer pump has weak suction and pulls air, which shows up as an engine that idles fine but pulls down or misses once it's loaded, even after fuel and air filters have already been changed. Worn injector springs and injectors that fill enough to run at idle but stumble under load are also commonly reported. Rack synchronization, fuel-load setting, and pump timing all need dedicated tooling and a careful procedure, so most owners send injection-pump work to a shop rather than doing it themselves.
How does the swing system typically misbehave as these machines age?
The recurring complaint on excavators of this platform and era is the machine creeping or drifting to one side when parked with hydraulics running, which points to the swing brake not holding fully — usually worn brake piston seals, a partially plugged screen in the brake's pilot plumbing, or a release valve spool that's sticking. Separately, swing motor and swing-gearbox wear tends to announce itself through metal or brass shavings turning up in the hydraulic filter well before the motor fails outright, and owners treat that as the cue to pull and inspect it rather than wait for a hard failure. Exact fault varies by configuration, so isolate with a pressure/leak check before replacing parts.
What undercarriage wear pattern should an owner expect on a 322 this age?
The press-formed roller frame on this platform is regarded as a durable, simple design, but on any excavator pushing thirty years old the undercarriage is the highest-wear, most exposed system on the machine. Owners commonly see uneven side-to-side wear depending on how the machine was worked — digging predominantly off one side accelerates wear on that track — and routine upkeep centers on watching track sag/tension, roller and idler condition, and sprocket tooth wear rather than any single failure mode unique to this model.
What's a typical final-drive failure mode on a machine like this, and how is it usually caught early?
The recurring complaint on Cat excavator final drives of this size and era is a leak at the joint between the sprocket and the travel motor, traced to a failed floating (duo-cone style) face seal. Once that seal goes, gear oil weeps out and lets contamination into the planetary hub, so owners who catch it early are the ones checking and topping off final-drive oil on a schedule and occasionally draining a sample to look for metal. Keeping the undercarriage clear of packed mud and debris is mentioned repeatedly as preventive, since compacted debris around the drive motor can push the face seal out of position.
Given the mechanical governor, what electrical or sensor problems actually show up on the 322?
Because engine fueling on this generation isn't electronically controlled, there's no engine fault-code diagnostics to chase — the electrical complaints owners report sit on the monitoring/gauge side instead. The most cited issue is sender wire failure: coolant-temp, hydraulic-temp, and oil-level senders with simple two-wire circuits that corrode or break and then feed a false high or low reading to the gauge cluster, sometimes tripping a basic circuit-fault indication on the monitor panel. Outside of sender wiring and the odd corroded connector, there isn't much electrical complexity to troubleshoot on this machine compared with later electronically controlled excavators.
What should a buyer check before purchasing a used 322 today, given it's roughly thirty years old?
Beyond the usual hour-meter and service-record review, community advice for a machine this age centers on: hydraulic leaks at cylinder rod seals, hose fittings, and pump housings; cycling every function through full travel while watching for drift, delay, or noise, especially whether the swing brake actually holds; final-drive oil level and a check for metal in the oil; undercarriage sag plus roller, idler, and sprocket tooth wear; and welded patches or cracking on the boom, stick, and undercarriage frame that hint at a hard working life. Because structural and hydraulic condition on a machine this old directly affects safe operation, have your dealer verify boom/stick welds and run a hydraulic pressure test before you buy.

Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
