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

The volumes divide the model groups and follow the same ten-section layout. Their model lists, engine applications, and S-Series/F-Series distinctions help match repair procedures and inspection data to the snowmobile being serviced.

Volume 1 specifications: Its technical-data tables exclude Swedish specifications, although Swedish variants appear in the model coverage list.

PDF Search, Bookmarks and Wiring Detail

Search and diagram navigation: Text search is partial: some introductory, service, and wiring pages lack searchable text; embedded bookmarks open the three volumes and their major sections. Small wiring labels require zooming, and wiring diagrams span consecutive page pairs.

One printable, English-language PDF contains 980 pages, including all six cover/title pages and 45 wiring-annex pages.

Engine Rebuilds, Drivetrain Service and Electrical Tests

The following is selected coverage, rather than a complete contents list; other topics include rewind-starter service and body/frame repair.

• Engine repair: Step-by-step top- and bottom-end disassembly and assembly, crankshaft inspection, leak testing, and fan- or liquid-cooling service.

• Fuel and oil systems: Mikuni carburetor service, dual- and triple-carburetor synchronization, fuel-pump checks, and oil-injection-pump adjustment.

• Clutches and drive belt: Total Range Adjustable (TRA) drive-pulley rebuilding, driven-pulley service, belt inspection, and pulley distance and alignment checks.

• Gearboxes and brakes: Chaincase and reverse-gearbox disassembly, drive-chain adjustment, mechanical brake service, and hydraulic brake bleeding.

• Electrical diagnosis: Ignition timing, starter-circuit troubleshooting, magneto and CDI tests, voltage-regulator inspection, and model-specific wiring diagrams.

• Rear suspension: SC-10 and Improved C-7 service, track and drive-axle work, and MX Z 440 HPG take-apart shock rebuilding.

• Steering and front suspension: Direct Shock Action (DSA) components, steering alignment, ski-leg camber, and ski and strut inspection.

Written primarily for snowmobile mechanics already familiar with Bombardier service procedures, these manuals assume suitable hand tools and the specified special service tools.

Engine Internals, Cooling and Rotary-Valve Service

The engine chapters distinguish the 247/277 singles, 377/443/503 fan-cooled twins, 454/494/582/583/670 liquid-cooled twins, and 599/779 triples. Assembly instructions address piston pins, circlips, matched crankcase halves, bearings, and crankshaft seals.

For the 277 engine, the seal-installation instructions identify MAG-side pusher P/N 4202778 75 and PTO-side pusher P/N 4208766 60. Exploded views identify fasteners and specified Loctite 242 or 271 applications.

Leak diagnosis: Engine leak-verification flowcharts distinguish potential leakage at crankshaft seals, the rotary-valve gear reservoir, and coolant-pump seals. These checks support fault isolation before committing to an engine teardown.

RAVE (Rotax Adjustable Variable Exhaust) coverage includes valve cleaning, passage and bellows inspection, valve-rod checks, and assembly dimensions. Related sections address thermostat testing, impeller inspection, rotary-valve timing, and coolant-pump and oil-reservoir assemblies.

Mikuni Setup and HAC Scope

Carburetor information includes float-level tables, jetting, throttle-slide settings, and model-specific idle adjustments. MAG-side, PTO-side, and center-carburetor settings are distinguished where applicable, along with oil-pump identification and synchronization.

High Altitude Compensator: The Summit HAC sections describe hose checks, routing illustrations, and replacement guidance. The HAC itself is maintenance-free; the manuals provide no adjustment or verification procedure for the unit.

Clutch Alignment, Reverse Gearboxes and Brakes

Pulley documentation includes TRA calibration-screw settings, driven-pulley spring preload, and the Pulley Alignment and Distance Specifications Chart. The chart identifies alignment template P/N 529 0267 00.

Gearbox sections cover the designated 2-speed units used on Touring SLE, Skandic 380/500, and Grand Touring models, plus the Skandic WT 3-speed unit. Exploded views accompany gear, bearing, shift-linkage, and reverse-lockout work.

Hydraulic brake scope: For Grand Touring SE and Mach 1, damaged calipers and master cylinders are replaced as assemblies; the brake sections cover pad service and system bleeding.

Ignition, Starting and Wiring Diagnosis

Troubleshooting charts address starting faults, weak or absent spark, lighting problems, and intermittent ignition symptoms. Nippondenso and Ducati CDI systems have separate test information, with resistance charts identifying wire colors and terminal pairs.

Ignition-timing data, spark-plug heat-range information, and CDI-module output tests accompany starter-motor inspection procedures. The electrical section also explains why an acceptable ignition-coil resistance reading does not rule out a fault at operating voltage.

SC-10, Improved C-7 and HPG Shocks

Suspension coverage distinguishes SC-10 Sport, Touring, Mountain, High Performance, and Cross-Country layouts, Improved C-7 twin-shock progressive-rate suspension, and Skandic WT suspension. Drive-axle shim-position views and sprocket-indexing illustrations accompany track and axle reassembly information.

MX Z 440 shocks: The HPG T/A (Take Apart) instructions cover seal replacement, revalving, floating-piston positioning, and nitrogen charging. Other HPG applications receive condition-check and replacement guidance.

The revalving section warns that undersized shim stacks can suffer fatigue breakage. Seal-carrier instructions identify seal pilot P/N 529 0265 00 to prevent seal damage.

Follow the manuals’ precautions for rotating drive components and pressurized nitrogen shocks; complex powertrain adjustments call for a qualified mechanic.

Examples of Engine Assembly and Shock-Clearance Data

Engine assembly specifications include 26 N·m (19 lbf·ft) for the 277 cylinder-head nuts and 22 N·m (16 lbf·ft) for the 503 crankcase bolts.

For the 494/582/583/670 engines, the crankshaft-seal section specifies a 1.0 mm (0.040 in) gap between plain seals and bearings for bearing lubrication.

The MX Z 440 HPG take-apart shock instructions specify approximately 0.203 mm (0.008 in) clearance between the rebound shim stack and stopper washer.
