2007–2011 Polaris IQ 550, 600, 700, 800, HO, Switchback, RMK, CFI, LX, Touring, Dragon, Shift, Widetrak, Assault Snowmobile Service Manual (P/N 9922854)

The Polaris IQ Service Manual (Reference 9922854, ©2010 Polaris Sales Inc.) covers the 2007–2011 550, 600, 700, and 800 models. It includes the HO, Switchback, RMK, CFI, LX, Touring, Dragon, Shift, Widetrak, and Assault configurations listed above.

Supplied as one English-language, 526-page PDF.

• Engine repair: Engine removal, top-end and crankcase overhaul, crankshaft inspection and truing, plus water-pump service and cooling-system bleeding.

• Fuel delivery: Mikuni carburetor service and Cleanfire fuel-injection diagnosis, including fuel-pressure testing, throttle-body synchronization, TPS base voltage calibration, and fuel rail bleeding.

• PVT and final drive: Drive clutch spider indexing, Team and Polaris P2 driven-clutch repair, chaincase service, and Widetrak transmission overhaul.

• Brakes and suspension: Brake caliper overhauls, hydraulic brake bleeding, track tension and alignment, steering adjustment, and FAST M-10 suspension setup.

• Electrical diagnostics: Model-specific wiring diagrams, ECU connector pinouts, fault-code interpretation, ignition tests, and charging-system checks for carbureted and CFI configurations.

• Shock service: Walker Evans, Ryde FX, and Fox procedures, with shock-specific disassembly, seal replacement, valve-stack specifications, and gas-recharging information.

This manual suits readers with a working knowledge of mechanical theory, tool use, and shop procedures; Polaris specifically recommends trained, authorized technicians for clutch service.

Engine and Chassis Specifications

Chapter 1 breaks down the core engine and chassis data into 54 model specification entries with matching clutch setting charts. Bore, stroke, displacement, cooling system capacities, and ignition specifications distinguish the 550 fan-cooled and 600/700/800 liquid-cooled powerplants.

Flywheel markings, including 4010677 for the carbureted 600 IQ Shift, help identify ignition components. The engine chapter adds inspection limits, clearances, and component-specific torque specifications for internal repair.

The 800 engine coverage includes cylinder-head, cylinder, and piston compatibility. It identifies the specification changes that apply after service bulletins S-09-08 or S-09-09, helping match an updated engine to the correct service data.

Fuel Delivery and Electrical Diagnostics

Mikuni VM and TM carburetors have separate service procedures. The Cleanfire sections distinguish CFI-4, DC-CFI-2, and DC-CFI-2+2 systems, including their injector layouts and electrical differences.

ECU connector pinouts, P-code and SPN/FMI tables, and Digital Wrench tests let you relate a reported fault to the correct circuit before selecting a repair. Fuel hose routing views and ignition timing charts support the model-specific checks.

Fuel-system work identifies pressure gauge PU-43506-A and the required adapters. ECU reflash procedures require separate Digital Wrench software, SmartLink hardware, and dealer authorization. Mismatched injector calibration or exchanging incompatible CFI ECUs can cause serious engine damage.

Clutch, Transmission, and Brake Repair

The PVT section separates Team LWT and Polaris P2 driven-clutch designs and identifies alignment tool PS-47477. It covers clutch offset, driven-clutch float, spring selection, and component inspection. Insufficient driven-clutch float can side-load the jackshaft and cause bearing failure.

Gear ratio speed charts accompany chaincase coverage. The Widetrak high/low/reverse transmission receives separate teardown and assembly procedures. Brake coverage extends to caliper pistons and seals; the Cyclone master cylinder is treated as a replacement assembly.

Suspension and Shock Service

Exploded front suspension assembly illustrations accompany camber, toe, and component service. Rear-suspension coverage distinguishes IQ coupled, RMK, Assault, Widetrak, and FAST M-10 layouts, including FRA adjustment and spring preload.

Shock valve shim stack configurations support Walker Evans and Ryde FX work, including remote-reservoir and IFP designs. Fox PS-5 coverage includes disassembly and seal replacement, but the assembly section stops before final reassembly and gas charging.

Snowmobile maintenance involves high-pressure EFI fuel lines and pressurized nitrogen in shock absorbers. Follow the manual's pressure-release and protective-equipment precautions.

File Format and Readability

The total includes five Notes pages and one blank closing page.

Embedded PDF bookmarks cover all 12 chapters and many individual procedures. Text search works through the main chapters and specification tables; many wiring-diagram labels are not searchable. Dense wiring diagrams need to be enlarged to read small pin numbers and wire codes.
