2006–2008 Polaris FS/FST Service Manual (P/N 9921066)

• Covers the 2006-2008 FS/FST range across Classic, Touring, Switchback, IQ, IQ LX, IQ Cruiser, Turbo LX, and Turbo Dragon variants, with VIN organization and model-number references for naturally aspirated and turbocharged 749cc configurations.
• Organizes 133 numbered model-specific tables covering engine data, altitude-based clutching, fuel delivery, electrical systems, gearing, tracks, and front/rear suspension setup.
• Details engine service and repair from in-chassis suspension and removal through cylinder-head, valve-train, crankcase, crankshaft, piston, balance-shaft, oil-pump, water-pump, flywheel, and timing-chain work.
• Traces Bosch M7.4.4 EFI and turbo systems with DTC definitions, ECU connector views, fuel-tank and pump service, pressure testing, wastegate and intercooler checks, Digital Wrench diagnosis, controller programming, and harness fault isolation.
• Handles PVT and final-drive repair with TEAM clutch alignment, belt-wear diagnosis, drive and driven clutch overhaul, spider indexing, chaincase service, jackshaft/driveshaft removal, and brake bleeding, caliper, pad, and disc procedures.
• Supplies chassis, suspension, and electrical documentation for steering alignment, IQ and M-10 rear suspensions, Ryde FX and FOX shock rebuilding, M-10 ACE testing, relay and PERC 4 circuits, harness routing, and year-specific wiring diagrams.

Coverage and Shop Level

This is the 337-page PDF of the Polaris FS / FST Service Manual, P/N 9921066. Coverage includes 2006 model codes S06PD7ES/FS, S06PT7ES/FS, and S06PS7FS; 2007 codes S07PD7FS, S07PF7FS, S07PP7FS/FE, S07PS7FS/FE, S07PT7ES/EE, S07PT7FS/FE, and S07PY7FS/FE; and 2008 codes S08PD7FS, S08PP7FS/FE, S08PR7FS/FE, S08PT7ES/EE, S08PT7FS/FE, and S08PY7FS/FE. The publication table identifies the 2007 FST IQ LX LTD, S07PF7FS, although that LTD version does not receive its own separate Chapter 1 specification sheet.

Polaris states that the manual was designed primarily for certified Polaris Master Service Dealer technicians working in a properly equipped shop. It is suited to trained mechanics who already understand mechanical theory, tool use, and standard shop practice; routine maintenance sections are accessible to experienced owners, while EFI programming, internal engine repair, clutch overhaul, and gas-shock work require the specified equipment and experience.

Repair and Diagnostic Depth

Twelve numbered service chapters cover model specifications, maintenance, engine removal, internal engine repair, final drive and brakes, PVT clutches, steering, front and rear suspension, chassis, and chassis electrical systems. The manual goes beyond basic replacement work with component inspection limits, bearing-clearance selection, torque patterns, shock valve-stack data, clutch calibration charts, electrical test values, and system-specific troubleshooting. Digital Wrench coverage includes live data, current and historic fault codes, guided diagnostics, service reports, ECU calibration reflashing, adaptation checks, and diagnosis of performance complaints that do not set a code.

Illustration coverage includes the engine lubrication-system overview, engine cooling-system routing, Bosch fuel-injection circuit and ECU pin views, PERC 4 forward/reverse controller circuit, M-10 ACE suspension schematics, and exploded views for the valve train, oil pumps, crankcase, timing drive, and starter. The final 24-page wiring section provides 2006, 2007, and 2008 chassis, engine, hood, system, and M-10 ACE diagrams as applicable.

Tools, Limits, and Service Cautions

Named equipment includes Digital Wrench software PU-47063, communication cable PU-47151, and ignition jumper PS-48463; timing-chain tools PW-46985, PW-47079, and PW-47108; TEAM clutch alignment tools PS-46998 and PS-47477; and shock gas-fill tool PS-45259. The manual notes that Digital Wrench updates and calibration files require authorized Polaris dealer or distributor access.

Turbocharger inspection is covered, but turbocharger disassembly is specifically not recommended because factory balancing can be disturbed; a defective unit is replaced as an assembly. On FST models, altering the factory-set wastegate actuator rod length can cause poor operation or severe engine damage. The PVT section also warns that using an impact wrench on the clutch bolt or puller can damage the clutch or crankshaft.

Follow the manual’s fuel-system precautions, use eye protection during clutch service, securely support the machine for track operation, and treat nitrogen-charged shocks as pressure vessels. These procedures are written as shop repair operations, not beginner-level instruction.
