2008 Polaris 600 RR / IQ Racer Snowmobile Service Manual (P/N 9921088)

This Polaris service manual, P/N 9921088, covers maintenance and repair for 2008 600 RR (S08MX6FS / S08MX6FE) and 600 IQ Racer (S08MX6JS / S08MX6JE) snowmobiles.

Supplied as one 170-page PDF, with 12 subject sections, including wiring diagrams, plus an index.

• Engine repair: Engine removal, cylinder and piston service, crankcase assembly, crankshaft inspection and truing, recoil starter repair, and Variable Exhaust System (VES) service.

• Fuel systems: Mikuni TM38 and TM40 carburetor disassembly, inspection, reassembly, throttle valve synchronization, fuel pump testing, and altitude/temperature jetting charts.

• PVT drive system: Drive and driven clutch rebuilding, spider indexing, clutch alignment and offset adjustment, belt deflection inspection, and belt wear diagnostics.

• Chaincase and brakes: Gear and chain service, shaft removal, bearing and seal replacement, hydraulic brake bleeding, and brake caliper, pad, and disc replacement.

• IQ Race suspension: Front and rear suspension assembly, steering alignment, control arm and spherical bearing replacement, rear skid removal, and track tension/alignment adjustments.

• Walker Evans shocks: Air, remote reservoir, and piggyback shock rebuilding, with internal floating piston settings, valve shim arrangements, and nitrogen charging specifications.

• Electrical diagnosis: Stator and sensor tests, Throttle Position Sensor (TPS) adjustment, ignition troubleshooting tables, and separate RR and Racer wiring diagrams.

Written primarily for certified Polaris Master Service Dealer technicians in a properly equipped shop, this manual assumes knowledge of mechanical theory, tools, and workshop procedures.

Liberty Engine and Fuel System Differences

The Liberty liquid-cooled engines have separate service specifications and assembly illustrations. The RR uses oil injection and Mikuni TM38 carburetors; the Racer uses premixed fuel and TM40s. These distinctions help match lubrication procedures and carburetor settings to the correct engine.

Internal repair coverage includes cylinder measurement, ring gaps, bearing fits, crankshaft indexing, and crankcase torque pattern drawings, with component-specific torque tables. Crankshaft checks address symptoms such as repeated plug fouling on one cylinder and unexplained piston failure. Engine data formulas cover compression ratio and port duration.

Cooling system diagrams identify the tunnel coolers, bypass circuits, and liquid-cooled brakes. Procedures cover water pump seals, thermostat housings and orientation, cooling system bleeding, and RR oil pump adjustment and bleeding. Fuel tank and exhaust pipe/resonator assembly views complete these sections.

PVT Clutches, Chaincase and Brake Service

Clutch spring, weight, and helix tables distinguish PERC and non-PERC configurations. The alignment section identifies different tools for standard and lightweight TEAM driven clutches, including PS-47477 for the lightweight version.

The manual warns that restricting driven-clutch float can side-load and damage the jackshaft bearing. Belt Wear / Burn Diagnostics and Chaincase Speed Charts connect drive-system symptoms and gearing choices with the service data.

Chaincase oil replacement, drive gears, jackshaft inspection, and brake hydraulic components receive separate coverage. The Racer slip driveshaft components and brake master cylinder assembly are specified as nonserviceable; master cylinder repair requires assembly replacement.

IQ Race Suspension and Walker Evans Shocks

Front suspension assembly illustrations show control arms and spindles. Separate steering layouts identify RR and Racer drag links; rear suspension views cover torque arms, rear idler wheels, and rail assemblies.

Suspension tuning covers ride height, torsion springs, limiter straps, and scissor stops. Shock Valve Shim Stack Configurations distinguish the RR and Racer valving; shock tables specify front track shock oil volume and nitrogen pressure, plus reservoir shock IFP depths.

Walker Evans rebuilding procedures identify the IFP tool PS-45908. The manual cautions that excessive valve-stack locknut torque can damage the stack. Spring-loaded clutches and nitrogen-charged shocks require the safety precautions and service equipment specified in the manual.

Periodic maintenance schedules and off-season storage procedures cover lubrication, drive and driven clutch inspections, fuel system preparation, and chassis care.

Ignition, TPS and Wiring Diagrams

The electrical section separates RR Detonation Control (DET) and Electronic Reverse (PERC) from the Racer's Dragon Fire pipe heater system. It also explains VES solenoid control and model-specific overheating responses.

Ignition timing checks, stator charge coil tests, sensor data, and No Ignition (Spark) / Incorrect Timing troubleshooting tables support electrical fault isolation. TPS testing and adjustment use tool P/N 2201519.

Four wiring sheets cover the RR chassis harness in two parts, the RR hood harness, and the IQ Racer, with connector identification and wire-color references.
