Ski-Doo Shop Manual: ELAN, TUNDRA II LT, SKANDIC 380/500, TOURING E/LE/SLE, FORMULA S/SL Snowmobile 1996 Service Manual (P/N 484 0628 00)

This 980-page official Bombardier PDF shop manual (Publication P/N 484 0628 00) is the definitive technical reference for the 1996 Ski-Doo lineup. It covers the ELAN, TUNDRA II LT, SKANDIC 380/500/WT, TOURING E/LE/SLE, and FORMULA S/SL/SLS/STX/LT/III models, alongside the GRAND TOURING, SUMMIT, MACH 1, and MACH Z series. Built for the bench, it delivers the exact factory specifications mechanics need to evaluate and repair the S-Series and F-Series chassis, along with the comprehensive range of 247, 277, 377, 443, 454, 494, 503, 582, 583, 599, 670, and 779 liquid- and fan-cooled engine configurations.

To significantly cut down on expensive dealership visits, this guide empowers the technician with specific procedures that would otherwise require a professional workshop.

• Comprehensive rebuilding steps for the Total Range Adjustable (TRA) drive pulley
• Step-by-step instructions for overhauling HPG Take Apart (T/A) shock absorbers
• Precise synchronization methods for dual and triple Mikuni float carburetors
• Accurate calibration techniques for the High Altitude Compensator (HAC)
• In-depth Rotax Adjustable Variable Exhaust (RAVE) valve cleaning
• Complete multi-speed gearbox and chaincase disassembly

Critical Sub-Assemblies Covered:

• SC-10 Sport, Touring, and Mountain rear suspension setups
• Improved C-7 twin shock progressive rate layouts
• Direct Shock Action (DSA) steering and ski leg camber
• Nippondenso and Ducati CDI ignition systems
• Liquid cooling system thermostats and impellers
• Rotary valve, coolant pump, and oil reservoir assemblies
• Rewind starter and oil injection pump integration

Component and System Documentation

The documentation is organized into ten core sections designed to streamline workflow. You get complete teardown and assembly breakdowns for both the top end and bottom end, alongside precise magneto and cooling system operations. The fuel and oil system chapters detail essential carburetor adjustments and oil pump identification for each engine variant. For the drivetrain, the guide maps out drive belt tolerances, pulley alignments, and brake system maintenance. Electrical troubleshooting is strictly data-driven, featuring clear ignition timing specs and starting circuit diagnostics.

Specification and Reference Data

Expect exact, model-specific fastener data to ensure reliable operation. Cylinder head torque values are set at 21 N·m for the 247 engine and 26 N·m for the 277. The manual specifies 31 N·m for engine support nuts and 38 N·m for engine mount nuts on the 247 type. When pressing crankshaft seals on the 277, the text references the exact factory pushers (P/N 4202778 75 for the MAG side and P/N 4208766 60 for the PTO side). Crankcase bolt torque is firmly established at 22 N·m for the 503. You will also find comprehensive spark plug heat ranges and CDI module timing charts. To rapidly diagnose faults and expedite assembly, the manual encompasses extensive wiring diagrams, engine leak verification flow charts, diagnostic troubleshooting charts, exploded assembly views, drive axle shim positioning views, and exact pulley alignment templates.

A frequent repair trap when servicing HPG take-apart shocks is omitting the 0.203 mm (0.008 in) clearance between the rebound shim stack and the valve stopper washer, which quickly leads to severe shim fatigue and breakage on rough trails. Furthermore, failing to maintain the exact 1.0 mm (0.040 in) gap between the plain oil seals and the crankshaft bearings on liquid-cooled engines will result in critical bearing starvation and a forced bottom-end teardown.

Because these specific torque thresholds and the recommended application of structural thread lockers like Loctite 242 or 271 are critical for safe machine operation, only qualified mechanics should attempt complex powertrain adjustments.
