Search live 966F II parts

The Caterpillar 966F Series II is a medium-to-large wheel-type loader powered by the Cat 3306 turbocharged diesel, a mechanically governed, pre-electronic engine rated in the 175 kW (235 hp) gross class. Operating weight runs roughly 20,485-21,500 kg (45,162-47,400 lb) depending on bucket, tire, and ballast configuration. Series II production ran roughly from the early-to-mid 1990s through 1998-2000, following the original 966F (built roughly 1990-1993) and preceding the 966G. Caterpillar offered the 966F II in several configurations built on the same base machine and Z-bar loader linkage, including standard general-purpose buckets, aggregate-handling packages for higher payload in pile work, and high-lift and waste-handling arrangements.

The Series II update carried over the 3306 engine and driveline from the original 966F but revised the cab, controls, and hydraulics, and is identified by its own serial number prefixes (1SL and 9YJ) separate from the earlier 966F's range. Because the 3306 is mechanically injected and pre-ECM, these loaders are mechanically simple to diagnose and rebuild compared with the electronically controlled 966G and later 966H/966M models, which keeps parts demand and rebuild activity for the 966F II steady in the used-equipment and parts markets. Large surviving populations in quarry, aggregate, and waste-handling fleets, plus broad parts commonality across the 966 family, make this generation a common source for used loader linkage, axle, transmission, and engine components today.

966F II fluids & capacities

SystemCapacityRecommended fluid
Engine crankcase (with filter) — Cat 3306 turbocharged diesel28 L (7.4 US gal)Cat DEO (Diesel Engine Oil) multigrade. Viscosity by ambient temperature per Cat's engine oil chart: SAE 10W-30 in cold climates down to about -20°C, SAE 15W-40 for moderate to warm climates. Commercial heavy-duty diesel oil meeting the equivalent API/Cat spec is an acceptable alternate.
Cooling system41 L (10.9 US gal)Cat DEAC (Diesel Engine Antifreeze/Coolant), full-strength ethylene-glycol premix or concentrate mixed with water, treated with the correct SCA (supplemental coolant additive) dosage per the maintenance interval. Standard mix is roughly 50/50 water-to-coolant; richer glycol ratio (up to about 60%) for extreme cold protection. Cat ELC (Extended Life Coolant) is the later factory-fill equivalent used on service refills of machines of this era.
Fuel tank304 L (80.4 US gal)No. 2-D diesel fuel meeting Cat's fuel spec (low sulfur). No. 1-D diesel recommended in cold-ambient climates for better cold-flow and startability.
Powershift transmission59 L (15.6 US gal)Cat TDTO (Transmission/Drive Train Oil), TO-4 spec. SAE 30 standard grade; SAE 10W in cold-climate service. Cat TDTO-TMS multiviscosity is an acceptable option where a wider temperature range is needed.
Front axle & differential (incl. planetary final drives)47 L (12.5 US gal)Cat TDTO (TO-4), same grade selection as the transmission — SAE 30 standard, SAE 10W in cold climates. Final drives are integral to the axle housing on this machine and share the axle fill.
Rear axle & differential (incl. planetary final drives)47 L (12.5 US gal)Cat TDTO (TO-4), same grade selection as the front axle — SAE 30 standard, SAE 10W in cold climates.
Hydraulic system (tank, lines, cylinders — incl. ride control accumulator circuit)205 L (54.2 US gal)Cat TDTO (TO-4) is the traditional factory recommendation for this generation of wheel loader hydraulic/implement circuit; Cat HYDO Advanced is the modern equivalent for service top-off. Grade selection follows ambient temperature — heavier grade in warm climates, SAE 10W or lighter in cold climates.
Grease (all chassis, linkage, and pin lube points)Per lubrication schedule — no reservoir capacityCat Multipurpose Grease (MPGM), NLGI 2. Cat Advanced 3Moly Grease is the extended-service alternative for high-load pivot points such as the loader linkage and bucket pins.

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

Servicing the 966F II beyond the schedule

Predictive Maintenance & Fluid Analysis

The 966F II's Cat 3306 has no onboard diagnostics, so trending is the main early-warning tool. Pull S·O·S samples from engine oil, powershift transmission, front/rear axle housings, and hydraulic tank on a fixed schedule and watch for rising iron, copper, or silicon that signals turbocharger, clutch pack, or final-drive wear. Since factory coolant on this era isn't extended-life, run Level 1 coolant tests for inhibitor depletion between changes. Track boost pressure and exhaust smoke by feel to catch injection pump wear before it costs power.

Corrective & Common Repairs

Common 966F II failure points trace back to the mechanical fuel system and Z-bar linkage. Expect injection pump and injector wear that shows up as hard starting, smoke, or lost power, needing pump calibration or injector replacement. Turbocharger shaft play from dust ingestion is frequent on quarry and aggregate machines. Loader linkage pins and bushings at the bell crank and tilt lever wear loose with heavy cycling, and lift/tilt cylinder rod seals leak with age. Powershift clutch packs and torque converter stators wear faster under aggressive shifting or hot operation.

Overhaul & Rebuild Points

At higher hours, plan overhaul work around the 3306's cylinder liners, pistons, and turbocharger, using compression and oil consumption trends to time an inframe rebuild rather than a fixed hour number. The powershift transmission clutch packs and torque converter, plus front and rear axle differential and final-drive planetaries, are the next major wear groups on this driveline. Z-bar loader linkage pins and bushings, lift/tilt cylinder seals, and the frame's center articulation pin and bushing are the mechanical wear points worth inspecting together during any major rebuild.

Seasonal & Environment Servicing

In cold climates, use an ether-assisted starting aid and a block heater for the 3306, and check coolant freeze protection since this era's fill is conventional, not extended-life coolant. Switch to a winter-grade hydraulic and engine oil viscosity for cold starts. In hot, dusty aggregate or quarry environments, shorten air cleaner service intervals and clean radiator and oil cooler fins more often to protect the turbocharger and cooling system. Tire pressure should be checked more frequently in temperature swings, and loader linkage grease intervals should tighten under heavy dust exposure.

966F II fault codes & troubleshooting

CodeMeaningLikely causeWhat to do
COOLANT TEMP - HIGH (red warning lamp + audible alarm)Engine coolant temperature has risen above the normal operating range.Low coolant level, plugged or dirty radiator core/screen, failed thermostat, or a slipping/damaged fan drive.Reduce load, let the engine idle to cool, check coolant level and radiator core for debris, and verify fan operation before restarting work. Do not remove a hot pressure cap.
HYDRAULIC OIL TEMP - HIGH (red warning lamp + audible alarm)Implement/steering hydraulic oil temperature has exceeded the normal operating range.Low hydraulic oil level, clogged oil cooler fins, a restricted return filter, or sustained high-load relief operation.Reduce hydraulic demand, check oil level and cooler for debris, change the return filter if due, and check for internal relief-valve bypass if the condition repeats.
TRANSMISSION (TORQUE CONVERTER) OIL TEMP - HIGH (red warning lamp + audible alarm)Power-train/torque-converter oil temperature is above the normal operating range.Low transmission oil, a worn torque converter, a clogged transmission oil cooler, or prolonged stall/converter-drive operation.Reduce throttle and load, idle to cool, check oil level and cooler, and have converter stall speed checked if the warning recurs.
ENGINE OIL PRESSURE - LOW (red warning lamp + audible alarm)Engine lubrication oil pressure has dropped below the safe minimum.Low engine oil level, a clogged oil filter, a worn oil pump, or a failed pressure sender.Shut the engine down right away, check oil level, and inspect the filter and sender before restarting.
CHARGING SYSTEM - NOT CHARGING (amber warning lamp)Alternator output is below what the batteries need to stay charged.A worn or slipping alternator belt, a failed alternator, or loose/corroded battery or alternator wiring.Check belt tension and condition, inspect wiring and battery connections, and bench- or load-test the alternator.
BRAKE SYSTEM PRESSURE - LOW (red warning lamp + audible alarm)Service/secondary brake accumulator oil pressure is below the safe operating minimum.A brake system oil leak, a failed brake charging pump, or loss of accumulator precharge.Stop the machine safely and do not move it until pressure is restored; check brake oil level and have the accumulator and charging pump tested.
MID 030 - CID 0248 - FMI 02 (Data Link - erratic/intermittent/incorrect data)Communication fault on the data link between the machine's electronic control modules, on a unit fitted with the optional electronic transmission/implement control.Damaged, corroded, or loose data-link wiring or connector pins between control modules, or a faulty control module.Inspect the data-link harness and connectors for corrosion or damage, clear the code, cycle the key, and retest; use a Cat service tool to confirm which module has dropped off the link if the code returns.

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

966F II attachments & work tools

General-purpose / rock buckets

Base bucket for this class runs heaped capacity around 3.6-3.7 cu m (4.7-4.8 cu yd) and struck capacity around 3.1 cu m (4.0-4.1 cu yd), with cutting width near 3.1 m (10.2 ft); figures vary by configuration/series. Rock/heavy-duty versions add bolt-on cutting edges, wear plates, a sloped floor and sharpened side bars for abrasive digging.

Bucket range by material density

Beyond the base GP/rock bucket, this loader is offered with lighter, higher-capacity buckets for low-density material and narrower heavy-duty buckets for dense rock. Exact capacity varies by bucket selected and dealer configuration.

Pallet forks

Fork carriages sized for the mid-size 966 loader class (frame widths around 1.8 m / 72 in) are documented fitting this machine, pin-mounted to the lift-arm/bucket linkage in place of a bucket for pallet and unit-load handling.

Log grapple / forestry work tools

A log grapple work tool is documented mounted specifically on this Series II loader for log and pulpwood handling. Grapple-type tools of this kind clamp hydraulically and need the machine's auxiliary hydraulic circuit rather than the base lift/tilt-only circuit.

Auxiliary hydraulics (3rd valve) kit

Base lift-arm hydraulics on this loader are a 2-valve (lift/tilt) circuit. A 3rd-valve auxiliary kit, adding an implement valve section, control and hydraulic lines, is required to run hydraulically actuated tools such as grapples, clamp forks or multi-purpose buckets.

Coupler / mounting system

Buckets and most work tools mount pin-on to the loader's lift-arm linkage. Dealer-fit mechanical quick-coupler kits (pin-grabber style, commonly a Balderson-type fitup) were offered for this generation to swap general-purpose and rock buckets without pulling pins; Cat's later hydraulic quick-coupler lines postdate this series and do not apply.

Automatic Ride Control

Optional accumulator-based ride control (lift-cylinder accumulator plus a diverter/solenoid valve) dampens bucket-load pitching when traveling loaded over rough ground or working into stockpiles, independent of which bucket or work tool is fitted.

High-lift arrangement

An optional high-lift boom/linkage arrangement is offered for extra dump clearance and reach, useful for loading over highwalls or into taller trucks. It trades some rated breakout force and static tipping load versus the standard-lift arrangement, so bucket size is typically adjusted accordingly.

Guarding / severe-duty options

Factory/dealer options for this class include axle and final-drive seal guards for quarry and rock-face work. Underbody and screen guarding is common on loaders this size for rock or waste-handling duty, but exact fitment for this specific series should be confirmed with a dealer.

Tires (work-tool stability/traction)

Tubeless nylon loader tires are offered in 23.5-25 and 26.5-25 sizes across multiple ply ratings, in bias or radial construction. Tire selection is matched to application (general duty vs. rock service) and affects stability when running heavier work tools like forks or grapples.

966F II serial number reference

On the 966F Series II the PIN/serial plate is mounted on the machine frame on the right-hand side, near the front of the loader close to the articulation joint; check there first before looking at the engine or cab. The plate carries the full Product Identification Number. The first three characters are the alphanumeric prefix (for example 1SL, 9YJ, or 8BG) that ties the unit to this model and production block, and the digits after it are the sequential unit number within that block. For 8BG-prefix machines, the digits matter: only S/N 8BG02000 and up are Series II.

Frequently asked questions

What engine does the Caterpillar 966F Series II use?

The 966F II is powered by the Cat 3306 turbocharged diesel, a mechanically governed six-cylinder engine (pre-electronic, no ECM) rated around 175 kW (235 hp) gross. It carries confirmed serial prefixes 1SL and 9YJ, distinct from the original 966F's serial range.

What is the operating weight of the Caterpillar 966F Series II?

Operating weight runs roughly 20,485-21,500 kg (45,162-47,400 lb), varying with bucket type, tire selection, and counterweight or ballast configuration.

What replaced the Caterpillar 966F Series II?

The 966G succeeded the 966F II as Caterpillar's next-generation medium wheel loader in this size class, continuing the 966 model line into the late 1990s and 2000s.

What 966F II owners discuss

What engine does the 966F Series II use, and are there real differences from the standard 966F?
Both use the Cat 3306 inline-six diesel, but the Series II runs the turbocharged-and-aftercooled 3306B TA, a meaningful step up in output over the naturally aspirated 3306B fitted to the earlier standard 966F. Published power figures vary by rating standard (gross vs net) and by source, so treat any single horsepower number as approximate and confirm against the data plate for a given serial range. Mechanics generally rate the 3306 as one of the easier Cat engines to work on - simple mechanical injection and a gear-driven water pump instead of a belt-driven one, which owners see as more reliable. Watch the water pump for weep-hole seepage as the first sign of bearing or seal wear, and treat rising coolant temperature seriously - overheating on this block is a known route to a warped head or blown gasket, especially if turbo/aftercooler air passages are dirty. Well-maintained turbocharged 3306 blocks are reported reaching well past 10,000 hours before needing an inframe.
What's the common transmission or torque converter complaint on the 966F II?
Slipping shifts, delayed or missed gear engagement (worse at higher engine RPM), and the machine unexpectedly dropping into neutral are the recurring complaints. Most trace to a worn torque converter, tired clutch packs, or a sticking transmission control valve rather than the transmission case itself. Some owners report torque-converter bearing failures where an internal bearing cage breaks up and lets the rolling elements migrate, allowing converter parts to rub - treat any new whine or metallic noise from the converter housing as an early warning, not something to keep running. Before condemning the valve body, check fluid level and condition and inspect the neutralizer pedal switch - a fouled or misadjusted neutralizer switch mimics a transmission fault.
Can the loader raise and curl the bucket at the same time, or is that a hydraulic fault?
On this implement valve, bucket curl/dump takes priority whenever the operator pulls both the lift and tilt levers together, so a simultaneous raise-and-curl or raise-and-dump move feels like the lift function is being ignored. That is normal valve behavior, not a defect. A genuine hydraulic problem shows up differently: implement pump noise paired with uneven cylinder rod speed and visible air or foam in the oil, usually traced to wrong oil viscosity, a loose suction-side fitting on the implement pump, or a main relief valve opening at too low a pressure. If implements go dead entirely, check the pilot pressure supply solenoid and pilot pump condition before assuming the main implement pump has failed.
Any wear patterns specific to this loader's linkage or running gear?
The 966F II runs on tires, not tracks, so undercarriage wear in the track-machine sense does not apply. Wear instead shows up in the loader linkage pins and bushings, the articulation (center) hitch pins, and tire tread. Pin-and-bushing life tracks directly to greasing discipline: a machine greased on schedule (as often as every few hours in sandy or muddy conditions) can still show tight, near-original pins after years of hard work, while skipped intervals show up fast as looseness and a sloppy, jerky linkage feel. Tire choice (tread pattern, ply rating, radial vs bias) varies by application and ground conditions, so tread wear rate varies by configuration rather than following one fixed number.
What electrical or sensor issues come up on the 966F II?
Most electrical complaints trace back to connectors rather than the sensors themselves - corroded or loose harness connectors cause intermittent no-starts, gauge dropouts, and false warning lights, and cleaning/reseating the connector often clears the fault before any part is replaced. The transmission and its neutralizer circuit run on 24V, so a weak battery bank or a charging-system fault often shows up first as odd transmission behavior rather than an obvious electrical symptom. Sensors owners commonly troubleshoot on this model include the neutralizer pedal position sensor, the transmission oil temperature and output speed sensors, and the fuel level sender circuit - a bad signal buffer in that circuit reads as an erratic or dead fuel gauge even when the tank sender itself is fine.
Anything to know before working on the brakes?
The 966F II uses inboard, oil-cooled disc brakes mounted at the differential rather than at the wheel hub, so any brake service means pulling the axle assembly and splitting the axle ends off the differential housing - it is not a simple wheel-off job. A low brake-pressure warning is most often low brake oil in the reservoir, an external leak at a hose or fitting, an internal wheel-brake seal leak, or a faulty pressure switch, so check fluid level and look for visible leaks first. Because this is the service brake system, have your dealer verify accumulator charge and brake system relief valve pressure before returning the machine to work.
What should a buyer check on a used 966F II?
Confirm the serial prefix and data plate against the machine's actual configuration - engine rating (naturally aspirated versus turbocharged 3306), transmission, and axle spec can differ across the production run, so match paperwork to what is actually on the machine instead of assuming. Cross-check indicated hours against physical wear evidence (pedal and control wear, linkage pin condition, tire wear) rather than trusting the meter alone. In the cab, check pedal and control feel, seat condition, and gauge function - rough controls point to hard prior use. Cycle every hydraulic function, including simultaneous lift and tilt, to confirm normal response, and listen for pump noise or uneven cylinder speed. Walk the loader linkage and articulation pins checking for play, inspect the frame for cracks or repair welds near the hitch and loader arms, and check the brake pedal for sponginess. Budget for inboard brake service being labor-heavy since axle removal is required, and have your dealer verify brake system condition and hydraulic pump output as part of a pre-purchase inspection.
