2021 Bobcat T76 Compact Track Loader Service Manual 7323984 – B4CE11001 & Above
This 2021 Bobcat T76 Compact Track Loader Service Manual 7323984 – B4CE11001 & Above is a detailed service and repair reference for the T76 compact track loader. The manual is written for loader mechanics and provides servicing and adjustment procedures for the machine, its component parts and its major systems. Across 904 pages it moves from routine maintenance and safe service preparation into hydraulic and hydrostatic testing, track and drive repairs, mainframe work, electrical diagnostics, engine service, HVAC procedures and machine specifications.
The manual goes well beyond routine maintenance. Component-level procedures include testing, removal and installation, parts identification, disassembly, assembly, pressure checks, adjustments and troubleshooting. Technical illustrations, component photographs, hydraulic and hydrostatic schematics, exploded views and service data are used throughout the Bobcat T76 service manual to support workshop diagnosis and repair.

Workshop Service and Diagnostic Coverage
The Bobcat T76 Compact Track Loader Service Manual 7323984 is structured around the systems a technician encounters during inspection, diagnosis and repair. Hydraulic coverage includes system information, troubleshooting, lift and tilt cylinders, Bob-Tach cylinders, the main relief valve, hydraulic control valve, lift arm bypass control, standard and high-flow hydraulic pumps, filters, reservoir, oil cooler, auxiliary hydraulic components and automatic ride control. Procedures include cylinder testing and rebuilding, pump tests, relief-pressure checks, valve service and hydraulic component removal and installation.
The hydrostatic section covers the hydrostatic drive system, drive motors, charge pressure, hydrostatic pump, two-speed and brake valve and drain manifold. It includes troubleshooting, fluid service, pressure testing, pump service, mechanical and hydraulic neutral adjustment and component disassembly and assembly. Detailed hydraulic/hydrostatic schematics are included for the T76, supporting circuit tracing and system diagnosis.
Drive-system information addresses the brake system and both solid-mounted and torsion-suspension track undercarriage configurations. Track tension checking and adjustment, track removal and installation, idlers, tensioners, rollers, sprockets, track frames and track damage inspection are covered. This makes the manual useful for repairs that extend from basic track maintenance to major undercarriage component service.
Mainframe procedures cover the seat bar, operator cab, seats, Bob-Tach assemblies, lift arms, rear grille, rear door, fuel tank, footrest, SJC control handles, access panels and cab windows. Procedures are supported by photographs and illustrations showing service locations, fasteners, pivots and component arrangements.
Electrical, Engine and HVAC Service
The electrical section provides coverage of the battery, alternator, starter, instrument panels, lights, Bobcat controllers, SJC drive controller, engine control unit, diagnostic service codes, Bobcat Interlock Control System, seat bar sensing and traction lock. It also covers electrical/hydraulic SJC controls, Service PC procedures, calibration, steering drift compensation, display navigation and settings, maintenance clock, alarms, horn and engine speed controls. This combination of service-code information, controller coverage and calibration procedures gives technicians a direct path from an electrical or control-system symptom to the relevant testing and service information.
Engine service includes engine information, diesel oxidation catalyst, air cleaner, cooling and lubrication systems, fuel system, cylinder head, crankshaft and pistons, camshaft, gearcase, turbocharger, flywheel and housing, exhaust gas recirculation system and exhaust manifold. The specification section identifies the engine as the Bobcat Engine / 2,4L Bobcat Engine Tier 4, a four-cylinder diesel with turbocharging and charged-air cooling. Engine procedures are supported by service data, torque information and dedicated engine service tools listed in the manual.
Heating, ventilation and air-conditioning coverage includes air-conditioning system flow, regular maintenance, troubleshooting, system charging and reclamation, compressor, condenser, receiver / drier, HVAC assembly, thermostat, expansion valve, evaporator coil, heater coil, blower fan, heater valve and automatic HVAC module. These sections provide service procedures for both mechanical HVAC components and the controls associated with the system.

Taken as a whole, the Bobcat T76 service repair manual links machine identification and preventive maintenance with system-level troubleshooting and workshop repair. A technician can move from a symptom or service code to system information, testing procedures and specifications, then continue into component removal, inspection, disassembly, assembly and adjustment where the manual provides those procedures.
Maintenance Data, Schematics and Specifications
The maintenance schedule identifies service requirements at intervals including every 10 hours, first and every 100 hours, 500 hours or 12 months, 750 hours or 12 months, 1000 hours or 12 months and 1500 hours or 24 months. It addresses engine oil and filters, cooling-system care, hydraulic filters and fluid, track tension, drive-motor brake cavities, batteries, controls, BICS functions and other regular checks.
Fluid and service information is supported by charts and specification pages. The manual includes fuel requirements, engine-oil recommendations, hydraulic-fluid information, fluid capacities, hydraulic pressures and flow data, cylinder specifications, electrical specifications, machine dimensions, operating performance and general torque information. For example, the loader specifications identify standard hydraulic pump capacity of 88,1 L/min (23.3 U.S. gpm), high-flow capacity of 114,7 L/min (30.3 U.S. gpm), and a system relief specification at the quick couplers of 23,8 – 24,5 MPa (238 – 245 bar) (3450 – 3550 psi).
Machine specifications also distinguish torsion-suspension and solid-mounted undercarriage data where applicable. The specification chapter contains rated operating capacity, tipping load, operating weight, travel speeds, engine data, drive-system details, hydraulic function times, electrical information, fluid capacities, track information and ground-pressure figures.
Repair the T76 with the Correct Procedures and Service Data
The 2021 Bobcat T76 Compact Track Loader Service Manual 7323984 – B4CE11001 & Above gives you the procedures and reference data needed for a wide range of T76 service work: scheduled maintenance, hydraulic and hydrostatic diagnosis, pressure testing, cylinder rebuilding, pump and valve service, track and undercarriage repairs, mainframe disassembly, electrical troubleshooting, controller and calibration work, engine repairs and HVAC service. Having the correct sequence, torque values, pressure specifications, diagrams and component illustrations at hand is especially important when a repair involves hydraulic pressure, internal components, machine controls or safety-related systems.
Delivered as an instant PDF after payment, there is no physical book and no shipping delay. Open the manual on a computer, tablet or phone, keep it available at the machine or workshop bench, and print the pages you need for the job.
