Engine, PVT, Driveline, and Electrical Service

These selected workshop topics show the scope of the manual. Other sections cover shift-linkage adjustment and diagnosis of the optional electric cargo-box lift.

• Engine repair: Engine removal and installation, top-end disassembly, cylinder and crankshaft inspection, valve and cylinder-head service, lubrication-system checks, and reassembly.
• Carburetor service: Separate Nikki and Mikuni procedures cover teardown, cleaning, inspection, fuel-level and leak checks, and jetting by temperature and elevation.
• PVT clutch service: Drive and driven clutch overhaul, bushing inspection, belt setup, clutch alignment and offset, and diagnosis of overheating or belt damage.
• Transmission and final drive: Transmission removal and internal repair, front gearcase troubleshooting, hub and CV boot service, prop shaft and U-joint work, and 6x6 mid-drive repair.
• Chassis and brakes: Body and cargo-box removal, A-arm and swingarm replacement, strut and ball-joint service, toe adjustment, hydraulic brake bleeding, and caliper overhaul.
• Electrical diagnosis: Separate TM starter and ECM checks and 2x4/4x4/6x6 CDI and cooling-fan tests, with charging and ignition flowcharts and wiring diagrams.

This manual is written for Polaris service technicians and experienced mechanics with the specified shop equipment. Polaris directs PVT maintenance and repair to certified Master Service Dealer technicians and specifies factory-authorized tools and procedures for clutch disassembly.

Robin V-Twin and Fuji Single-Cylinder Engines

Ranger TM: The air-cooled Robin EH63 uses wet-sump lubrication and a Nikki downdraft carburetor. Its engine chapter covers the oil-flow path, crankshaft runout, cylinder honing, and checks during reassembly and installation.

Ranger 2x4, 4x4, and 6x6: The liquid-cooled Fuji EH42 and EH50 use dry-sump lubrication and Mikuni BST 34 CV carburetors. Their engine section also covers cam-chain timing, valve-seat reconditioning, crankcase bearings, counterbalancer end play, oil-pump priming, water-pump seals, and sealed recoil starter repair. The flywheel procedure warns that puller bolts threaded in too far can damage the stator coils.

Clutch Setup and Driveline Differences

The TM has its own PVT hardware and uses alignment tool PA-47043. The 2x4, 4x4, and 6x6 use alignment tool 2870654, with clutch calibration charts by application. The transmission chapter includes exploded views and inspection procedures for shift drums, forks, engagement dogs, shafts, and silent chains.

The final-drive chapter distinguishes the TM and 2x4 front hubs from the driven hubs on the 4x4 and 6x6. It gives the 6x6 separate mid-hub, mid-shaft, and mid-gearcase procedures. The mid-driveshaft section explains how yoke alignment affects vibration and how distorted or misaligned yokes can cause premature U-joint failure.

Brake and Electrical References

The brake chapter covers master-cylinder operation, pad and disc wear limits, and front and rear caliper repair. The electrical chapter includes starter tests, coolant-sensor and fan-motor checks, gear-indicator diagnosis, and separate wiring diagrams for the TM and the 2x4/4x4/6x6 group.

Use the parts manual for your exact model when selecting replacement parts and applicable fasteners. Securely support the vehicle for suspension and final-drive work, and follow the manual’s fuel, brake-fluid, battery, and rotating-PVT precautions before beginning any repair.

Examples of Engine Inspection and Cooling Test Data

For the Fuji EH42 and EH50 engines, the service-data table gives a crankshaft runout limit of 0.0024 in. (0.06 mm).

The cooling-system leak test for those engines specifies that the system must hold 10 psi for at least five minutes.
