1998 Ski-Doo Tundra II LT, Touring E/LE, Formula S/S Electric/SL, Skandic 380/500 Snowmobile Shop Manual Set (P/N 484 0680 00)

Use Volume 2 alongside the MX Zx 440 LC and Summit x 670 supplements. The Tundra R and Touring SLE supplement uses Volume 1 for shared procedures and adds model-specific service information.

The set covers factory configurations as built. High-altitude carburetor and transmission calibration data are in the separate High Altitude Technical Data Booklet (P/N 484 0686 00). For HPG Racing damper teardown and reassembly, the MX Zx supplement refers to the shop manual and a separate Racing Handbook.

PDF Bookmarks, Search, and Wiring Diagrams

Text search and diagram detail: The service text is searchable. The illustrated covers and wiring diagram sheets are outside the text search. Embedded bookmarks open all six publications, with chapter shortcuts for the three main volumes. Zoom in for small connector numbers and wire color codes.

The six publications come in one printable, 1,155-page PDF, including their illustrated covers.

Engine, Clutch, Chassis, and Electrical Service

This selection of workshop topics also includes examples from scheduled maintenance, such as headlight aiming and rewind starter rope replacement.

• Engine repair: Step-by-step procedures cover engine removal, top-end work in the chassis where applicable, crankcase disassembly, bearing and seal installation, and leak testing.

• Fuel, oil, and cooling: Carburetor synchronization, choke and float settings, fuel pump tests, oil injection pump adjustment and bleeding, and service for fan-cooled and liquid-cooled engines.

• Clutches and gearboxes: Bombardier Lite, TRA, and TRAC pulley service, drive belt adjustment, chaincase inspection, mechanical gearbox repair, and electronic reverse diagnosis.

• Ignition and electrical: Nippondenso and Ducati CDI timing and tests, charging and lighting checks, battery service, electric starter overhaul, and model-specific wiring diagrams.

• Brakes, suspension, and steering: Mechanical and hydraulic brake service, caliper and master cylinder work, track and drive axle removal, ski alignment, and DSA front suspension service.

Bombardier wrote these publications primarily for snowmobile mechanics familiar with its service procedures and equipped with the specified hand tools and special service tools.

Engine Inspection and Fuel Setup

The engine sections cover types 277, 377, 443, 454, 494, 503, 583, 599, 670, 699, and 809 across the set. Inspection data cover cylinder taper and out-of-round, piston and ring clearances, connecting rod wear, surface flatness, and crankshaft deflection, end play, and alignment. Dedicated sections address RAVE valves, rotary valve lubrication, and coolant pump service.

The Engine Leak Verification Flow Chart helps separate a leaking test setup from leaks at engine seals or joints before teardown. The 377, 443, and 503 use factory-matched crankcase halves, and scratches on the mating faces can compromise sealing. On twin-carburetor engines, side-specific jetting and the link between carburetor adjustment and oil pump synchronization matter because incorrect setup can damage the engine.

The MX Zx 440 LC supplement explains its premix fuel setup, the oil pump’s role in rotary valve lubrication, and its three-radiator layout in the Liquid Cooling Flow diagram.

Drive Alignment, Brakes, and Running Gear

The Pulley Alignment and Distance Specifications Chart ties alignment tools and settings to the drive configuration. Gearbox procedures cover bearings, seals, sprockets, shift mechanisms, and drive chain setup. Brake chapters cover pad and disc inspection, mechanical cable adjustment, hydraulic fluid replacement, and bleeding.

The rear suspension sections distinguish Torque Reaction, SC-10, Formula Z 670, and Skandic WT designs. They cover track tension and alignment, with exploded SC-10 assemblies alongside the service procedures. Body and frame service and MX Zx HPG Racing remote-reservoir service are also included. Follow the applicable chapter warnings when working around rotating clutches and tracks or pressurized shock reservoirs.

Wiring, Fault Tracing, and Factory Tools

The wiring annexes and connector location views let you match the circuit to the machine before testing. The Summit x 670 supplement includes a DESS component location view, tether programming, and tests for the MPEM and Digital Performance Management system. The introductions identify S-Series, Skandic WT Series, and CK3 chassis and show where to find vehicle and engine serial numbers.

The tool lists distinguish required and optional equipment. Examples include the engine leak tester kit (P/N 861 7491 00), magneto puller (P/N 529 0225 00), piston pin puller (P/N 529 0290 00), alignment templates (P/N 529 0267 00, 529 0269 00, and 529 0300 00), and DESS programmer (P/N 529 0355 02).

Piston Clearance and Clutch Engagement Examples

For the MX Zx 440 LC’s 454 engine, the specification table lists a new piston-to-cylinder wall clearance of 0.1 mm (0.0039 in) and a wear limit of 0.15 mm (0.0059 in).

The vehicle tables list clutch engagement at 2,500 rpm for the Touring E and 2,900 rpm for the Touring LE, each with a tolerance of ±200 rpm.
