2000 Ski-Doo Mini Z & Mini-Z 120 Shop Manual (P/N 484 200 017)

• A 156-page PDF of the Ski-Doo Mini Z shop manual, 2000 edition, marked 484 200 017 on the cover.
• Covers engine removal, valve adjustment, internal engine disassembly and reassembly, compression testing, and component measurement.
• Carburetor service includes float-level checks, idle adjustment, governor setup, and fuel-tank check-valve testing.
• Details clutch replacement, mechanical brake service, and drive-chain inspection and lubrication, with checks for the automatic chain tensioner.
• Explains transistorized magneto ignition service and rewind starter repair, with electrical tests and a MINI Z wiring diagram.
• Chassis procedures cover rear suspension and drive-axle service, track tensioning and alignment, steering linkage inspection, and ski adjustment.

This reference covers the 118 cc, single-cylinder, four-stroke OHV power unit and its driveline. It was written for snowmobile mechanics already familiar with Bombardier service procedures and assumes access to the specified hand tools and special service tools. Its eleven major sections cover the factory-built machine; later dealer modifications fall outside this edition’s scope.

Four-Stroke Engine Repair

The engine chapters extend beyond cylinder-head work to crankshaft and camshaft removal, centrifugal governor components, piston-ring positioning, and timing-mark alignment. Top End and Bottom End exploded views accompany the disassembly and assembly procedures.

Inspection methods address valve stems, guides, and seats, as well as cylinder-head flatness. Piston, cylinder, ring, and connecting-rod measurements have standard dimensions and wear limits; the connecting-rod bearing check includes a Plastigauge method.

The rewind starter section covers rope and spring replacement, spring lubrication, and ratchet operation. Flywheel service includes a specific repair caution: holding the flywheel at its magnet can damage the flywheel.

Ignition and Fault Diagnosis

Symptom charts address starting failures, irregular idle, power loss, rich or lean running, lighting faults, and track or steering problems. The “Engine Turns Over but Fails to Start” chart connects the symptom to fuel delivery, ignition, valve clearance, and compression checks.

Separate multimeter test views cover the ignition coil’s primary and secondary sides, spark plug cap, and lamp coil. Wiring information identifies connector positions and wire colors, along with the key switch, tether cut-out switch, emergency kill switch, headlight, and taillight circuits.

Driveline and Chassis Service

The clutch chapter describes removal, inspection, and replacement of the assembly. It specifies complete clutch assembly replacement when the clutch is damaged because individual repair parts are not supplied separately. The brake drum forms part of the clutch cover, so a drum requiring replacement also calls for a clutch assembly. A brake-pad installation caution explains how overtightening its retaining nut can damage the pad.

Suspension service covers torsion springs, idler wheels, stopper straps, and slider shoes. Drive Axle and Steering System exploded views and accompanying procedures document bearing replacement, sprocket positioning, ball-joint inspection, and ski toe-out adjustment. Camber is identified as nonadjustable.

Body and frame sections address headlight aiming, cable routing, seat removal, and frame repairs.

Engine and Chassis Specifications

Reference data includes general metric-fastener torque tables, component-specific tightening specifications, fluid capacities, carburetor settings, and electrical test values. The maintenance chart organizes dealer inspections, storage preparation, and recurring maintenance manual procedures, including engine-oil changes and fuel-strainer cleaning.

Listed special tools include the flywheel holding tool (P/N 529 006 400) and float level gauge (P/N 529 035 520). Drive-axle work references the sprocket adjuster (P/N 861 725 700).

Please keep in mind that this document contains service data for informational reference. Always follow standard shop safety protocols and the manufacturer’s precautions for the rotating track, drive chain, and brake system.
