Depth:
Comprehensive: Covers basic maintenance to full component overhaul and system diagnostics.
Diagnostic Tools:
While not explicitly listing diagnostic tools, the manual provides the information necessary to diagnose issues using standard mechanical and electrical testing methods.
Visual Aids:
Includes pictures and part diagrams for clear understanding of assembly and procedures.
Engine Type:
Rotax 2-Stroke (Specific displacement and configuration depend on the exact model within the REV chassis, e.g., Rotax 377, 440, 500, 550, 593, 600, 700, 800 series)
Horsepower Range:
Varies significantly by engine. Typically from 60 HP (smaller displacements) to over 130 HP (larger displacements) for this era.
Torque Range:
Varies significantly by engine. Typically from 45 ft-lbs to over 90 ft-lbs.
Induction:
Carbureted (e.g., Mikuni, Dell'Orto) or Electronic Fuel Injection (EFI) depending on specific model variant.
Fuel:
Unleaded Gasoline (Octane requirement specified by model, typically 87 or 89 octane)
Oil System:
Pre-mix or Oil Injection System (automatic oil injection is common for this era)
Pre Ride Inspection:
Daily (visual inspection of track, skis, suspension, controls, fluid levels).
Regular Maintenance:
Mileage/Usage based (e.g., 1000 miles, 50 hours). Specific intervals for clutch inspection, chaincase oil change, spark plugs, etc., are detailed in the manual.
Major Overhaul:
As needed or per specific high-mileage recommendations for engine components.
Engine Oil:
For oil injection systems: Specific Ski-Doo branded 2-stroke synthetic oil recommended. For pre-mix: Specific 2-stroke synthetic oil meeting JASO FD or API TC standards.
Chaincase Oil:
Hypoid gear oil, SAE 80W-90. Specific part numbers and capacities in manual.
Coolant:
Ethylene glycol based antifreeze, mixed 50/50 with distilled water. Specific capacity in manual.
Brake Fluid:
DOT 3 or DOT 4 brake fluid, depending on specific caliper/master cylinder design.
Common Wear Items:
Drive belts (due to heat and tension), clutch rollers/weights, suspension bushings, track lugs (on aggressive terrain).
Potential Failures:
As with any machine of this age, components like fuel lines, cooling hoses, electrical connectors, and suspension bearings can degrade over time and require inspection/replacement.
