Main Frame, Cab & Panels

The main frame chapter documents the structural heart of the T770, with exploded views covering crossmembers, louvers, side covers, access covers, shields, bushings, weld-on hinges, brackets, and the sight gauge. The operator cab section is equally detailed, covering cab replacement, gas spring assemblies, interior panels for both standard and deluxe configurations, headliners, HVAC components, seat bars for BICS and SJC systems, seat and seat belt assemblies, and the cab electrical circuitry for standard and deluxe harnesses. The panels chapter covers the floor pan for manual controls, AHC, ACS, and selectable joystick control configurations, including foam insulation, boots, pedals, and mounting hardware. Every exploded view carries numbered callouts that correspond directly to the parts list, so you can trace each component from diagram to part number without ambiguity.

Drive Train & Undercarriage

The drive train coverage in this T770 parts manual is extensive and serial-number specific. It documents both solid mount and suspension track frames, rubber and steel track options, front and rear idlers, track rollers, track tensioners, and sprockets for single-speed and 2-speed motor configurations. The hydrostatic motor chapters break down the single-speed and 2-speed drive motors into their internal components — pistons, bearings, seals, brake discs, distributor, housing, and shaft assemblies — so you can rebuild rather than replace when that makes sense. The hydrostatic pump and gear pump sections provide the same level of detail, with exploded views covering the rotary groups, control modules, charge pressure relief valves, and all internal sealing components. Serial number breakpoints are clearly noted throughout, ensuring you order the correct variant for your machine’s production range.

Hydraulic & Hydrostatic Systems

The hydraulic circuitry chapters document the complete fluid power system for both configurations — with and without the BPV junction block. You’ll find the hydraulic control valve for manual, AHC, ACS, and SJC control types, along with the gear pump, hydrostatic pump, cooling fan motor, 2-speed valve, brake valve, and every hose, tubeline, fitting, clamp, and coupler in the system. The hydrostatic circuitry section covers the tank and filter assembly, the cooler circuit, the cooling fan circuit, and the single-speed and 2-speed motor circuits. The exploded views and circuit diagrams make it possible to trace every line and connection, which is invaluable when you’re diagnosing a leak, replacing a hose, or rebuilding a valve. The cooling system chapter covers the fan, shroud, hood, screens, seals, and mounting hardware, with serial number breakpoints for the different cooling system configurations used across the T770 production run.

Engine, Fuel & Exhaust Systems

The engine section provides parts breakdowns for the V3800DIT engine used in the T770, including the cylinder head and cover, camshaft, pistons, crankshaft, oil pan, front cover, water pump, thermostat, turbocharger, EGR valve, intake and exhaust manifolds, and the fuel injection system with injectors, injection lines, and the fuel injection pump. The governor chapter documents the mechanical governor assembly with its weights, levers, springs, and solenoid shutoff. The fuel system chapters cover both single-tank and dual-tank configurations, with all associated hoses, brackets, filters, primer pumps, fuel sensors, and tank mounting hardware. The upper and lower gasket kits are listed with every gasket, O-ring, and seal needed for engine reassembly, making it straightforward to order everything you need in one go. The air cleaner chapter covers the outer and secondary filter elements, housing, cover, and gaskets for both the early and later air cleaner assemblies.

Electrical Systems & Controls

Electrical coverage in this parts manual spans the cab harness, engine harness, frame harness, controllers, sensors, fuses, relays, switches, solenoids, and lighting. Both standard and deluxe cab electrical systems are documented separately, along with the specific connectors, terminals, seals, and wedges used throughout the machine. The controls electrical section covers the handle assemblies for manual controls, selectable joystick controls (SJC), advanced control system (ACS), and advanced hand controls (AHC), including the joystick bases, boots, handles, sensors, solenoids, and wiring harnesses. The engine electrical circuitry chapters document the frame harness, filter sensors, engine sensors, battery, alternator, and starter, with serial number breakpoints for the different harness configurations used across the T770 range. This makes it possible to troubleshoot electrical faults accurately and order the exact replacement components for your machine.

Accessories & Options

The accessories and options section is particularly comprehensive, covering the many kits and attachments available for the T770. This includes ACS conversion, auxiliary flow, back-up alarm, beacon, block heater, brake lighting, bucket position valve, bumper, cab door, cab enclosure, cab seal, cab windows, chrome pin, counterweight, coupler guard, cup holder, cylinder cushion, debris shield, decals, deluxe headliner, deluxe interior, electrical controls, engine compartment seal, European accessories, FOPS, fire extinguisher, flasher lights, fuel sediment bowl, gas spring, heater and A/C, HEPA filter, horn, hose guide, intermittent wiper, isolator mount, keyless panel, lift cylinder cushion, lift kit, light guard, loader LED light, maintenance platform, muffler guard, muffler/purifier, neutral lighting, pedal extenders, Power Bob-Tach, radio, rear auxiliary, rear wiper, remote control, resealing, reversing fan, ride control, seat options, security locks, shield kits, side light, sound/noise reduction, steering dampener, steering linkage support, steering pattern control, strobe light, tracks, vinyl cab, and white decal kit. Each kit listing includes the individual part numbers for every component in the kit, so you can order the complete kit or just the specific parts you need.

Why This Bobcat T770 Parts Manual Matters

When you’re repairing or maintaining a Bobcat T770 Compact Track Loader, using the wrong part number means wasted time, incorrect fitment, and unnecessary expense. This manual eliminates the guesswork by providing the exact part numbers Bobcat uses for every component, organized by assembly and serial number range. Whether you’re replacing a worn bushing, rebuilding a hydraulic cylinder, ordering a complete new assembly, or converting your machine with an accessory kit, the exploded views and parts lists in this manual give you the confidence that you’re ordering the right part the first time.

The serial number breakdowns are particularly valuable — the manual notes where parts differ by serial number range, so you can match the parts to your specific machine rather than guessing based on the model year alone. This is especially important for components like the lift arm links, drive train assemblies, hydraulic control valves, hydrostatic motors and pumps, cooling system components, electrical harnesses, and fuel system parts, which changed across production runs. Having this manual means you can identify the correct variant for your machine’s serial number without relying on a dealer’s parts counter or trial-and-error ordering.
