Yamaha SX500D, SX600D & SX700D Snowmobiles (2000-2001) - Comprehensive Service Manual

Yamaha SX Series Snowmobile Service Manual - 2000-2001 Edition

This professional workshop publication provides detailed repair protocols and diagnostic sequences for the Yamaha SX liquid-cooled two-stroke fleet. Uptime is maximized through the integration of critical procedural warnings, such as the mandatory 24-hour curing period required after applying Loctite® to chassis fasteners to ensure structural integrity under high-vibration operating conditions.

Technical Depth & Factory Benchmarks

Engine architecture is detailed via forward-inclined parallel cylinder configurations featuring piston or crankcase reed valve induction systems. Technical specialists can reference specific lubrication parameters for the Yamaha Autolube system, including oil tank capacities of 3.0 liters and recommended Yamalube 2-cycle lubricants. Chassis dynamics are supported by leading arm front suspensions and Proaction system rear slide rail setups, both requiring precise nitrogen gas pressure management.

System Navigation & Schematics

Visual aids facilitate the removal and installation of complex drive systems, including the secondary sheave assembly, drive chain housing, and front axle tracking. Cable routing diagrams provide specific pathways for fuel breather hoses and oil level switch couplers to prevent kinking or interference with the steering column.
