Complete Manual Information
Polaris EDGE & WIDETRAK Service Manual - 2008 Edition
Technical proficiency is established through the application of factory-validated procedures and exacting tolerances. This manual provides the precise torque sequences and calibration data necessary to maintain structural integrity and powertrain efficiency. A hyper-specific maintenance critical is the requirement to set the torque stop bumper-to-engine gap between .010" and .030" (.25-.75mm); failure to maintain this precise clearance results in excessive engine movement, leading to premature drive belt failure and misaligned clutch center distances.
Chassis Architecture & Technical Applicability
This documentation governs the maintenance of the following 2008 model year snowmobiles, categorized by engine displacement and chassis configuration:
EDGE Chassis (Standard & Touring Configurations)
- 340 Piston Port Series: Models S08NB3AS (Standard) and S08NT3AS/S08NT3AE (340 Transport).
- 550 Cylinder Reed Series: Models S08NP5BS/S08NP5ES (Supersport), S08ND5BS (550 LX), and S08NT5BS/S08NT5BE (Trail Touring Deluxe).
EDGE RMK Deep Snow Configurations
- 550 RMK Series: Models S08NJ5BS/S08NJ5BE (Trail RMK).
WIDETRAK Utility Chassis
- 488 Liquid-Cooled Series: Models S08SU4BS/S08SU4BE (Widetrak LX).
Service Lifecycle & Operational Reliability
- Precision torque sequences for crankcase and cylinder head fasteners ensure thermal stability and prevent head gasket failure.
- Detailed Mikuni VM carburetor jetting charts provide altitude-specific calibrations to prevent lean-burn conditions during high-elevation operation.
- Suspension assembly schematics include exact rod end engagement guidelines to maintain steering geometry and operator safety.

- Primary Coverage: Engine, Fuel, PVT, Chassis, and Electrical Systems
System Calibration & Powertrain Benchmarks
Powertrain performance is regulated by specific engagement parameters and mechanical clearances. The Fuji fan-cooled 339cc engine utilizes a 1600 RPM idle set point and a 4100 RPM engagement speed, while the 544cc variant targets a lower engagement of 3800 RPM. Internal benchmarks require a piston-to-cylinder clearance of .0039"-.0053" (.10-.135mm) for the 550 series to ensure optimal compression and thermal expansion management.
Transmission & Drive Mechanics
The PVT (Polaris Variable Transmission) system relies on exact drive belt deflection of 1.25" (3.2cm) to maintain the correct initial starting ratio. Technicians must verify clutch offset using factory alignment tools (PS-46998 or PS-47477) to prevent side-loading and premature jackshaft bearing failure.
