1985–1995 Polaris Indy 500, Indy 650, XLT, RXL & Storm Snowmobile Service & Repair Manual (P/N 9912121)

The Polaris Snowmobile Master Repair Manual, Volume 2, covers 1985–1995 models, including Indy 500, Indy 650, XLT, RXL, and Storm variants. Publication P/N 9912121 brings together model identification, service specifications, troubleshooting, and repair procedures for the covered fan-cooled and liquid-cooled machines.

• Engine repair: Engine disassembly and reassembly, piston and cylinder inspection, crankshaft truing, crankcase bearing-fit checks, and recoil starter repair.

• Fuel and cooling systems: Mikuni carburetor synchronization, altitude and temperature jetting compensation, fuel-pump service, oil-pump bleeding, and model-specific cooling-system documentation.

• Clutches and final drive: Torque-O-Matic drive service, P-85 and P-90 clutch work, belt adjustment, drive-system overhaul, and Series 300 transmission overhaul.

• Brake service: Hydraulic master-cylinder and caliper overhaul, mechanical brake inspection and pad replacement, system identification, and bleeding procedures.

• Steering and suspension: IFS toe and camber adjustment, XTRA ski alignment, track removal and alignment, and Fox IFP shock rebuilding.

• Electrical diagnosis: Lighting, ignition, charging, starter, and warmer tests, with wiring diagrams, EFI sensor checks, ECU fault codes, and Select Monitor data.

This manual is suited to technicians experienced in two-stroke engine and chassis service, with access to the measuring instruments and specialized equipment specified for the work.

Engine, Carburetor, and Cooling Service

Engine chapters distinguish PS singles, PL twins and triples, reed-valve and monoblock designs, and PM twins. Assembly references include cylinder-head torque tables and tightening patterns, piston identification, rebuild clearances, and service limits.

Mikuni coverage includes throttle and choke adjustments, synchronization methods, and jetting compensation charts. Fuel-pump exploded views distinguish the assemblies used on Lite, Sport, twin-cylinder, and triple-cylinder applications.

Cooling-system illustrations show different recovery and positive-bleed arrangements, including the EC65PL-05 and EC80PL-02 systems. Oil-pump operation, troubleshooting, bleeding, and adjustment are covered separately.

Torque-O-Matic Drive, Brakes, and Transmission

Shift-weight and spring-rate charts support clutch calibration for engine characteristics and operating conditions, including altitude and heavy loads. The service sections also cover clutch alignment, belt deflection, spider inspection, and spider indexing.

The drive-clutch section explains how impact-wrench use can loosen the spider and damage the engine crankshaft.

Brake chapters distinguish hydraulic master cylinders and calipers from mechanical brake assemblies. Series 300 transmission coverage extends to gear clusters, the silent chain, detent adjustment, bearings, seals, and installation-related jackshaft alignment.

IFS, XTRA Suspension, and Body Repair

Suspension identification charts connect the different suspension types to their applications. Track service includes tension and alignment checks, Hi-Fax and track-clip replacement, and WideTrak transmission, suspension, and track removal.

Fox IFP sections cover disassembly, seal inspection, internal floating piston positioning, fluid replacement, and recharging. Shock-valving charts accompany the procedures; the XTRA service section identifies the gas shock recharging kit and body-cap holding tool required for that work.

Body and steering coverage includes storage preparation, fuel-tank and seat removal, seat-cover replacement, nosepan repair, and steering-linkage adjustments.

For RIM Metton hoods, the repair section distinguishes two-part material repairs from heat welding, which can make the material bubble, char, and become brittle. Major damage requires replacement of the affected part.

Electrical Testing and EFI Fault Isolation

Model-specific wiring diagrams and stator schematics accompany ignition timing advance curves and component test data. Lighting, seat harnesses, switches, handlebar warmers, thumbwarmers, and electric starters have their own test coverage.

The EFI sections distinguish the RXL Type I system from the 500 EFI Type II system, including the different power-up arrangements used across production versions. Those distinctions help technicians select the appropriate power-supply and control-circuit tests when diagnosing starting or running faults.

Select Monitor instructions identify Polaris tool 2870969 and cover sensor readings, ECU memory, and fault-code interpretation. Fuel-pressure testing and throttle-position sensor checks provide additional ways to isolate fuel-delivery and control faults.

Always review all factory-specified procedures before service and make sure you have the mechanical expertise and equipment needed for the work, particularly pressurized shock service.

A Preview of XTRA Shock Rebuild Specifications

These values are a small sample of the component-specific rebuild data in the manual.

For the XTRA IFS ski shock 7041385 and front track shock 7041386, the table specifies an initial IFP depth of 7.75 inches and a suspension-fluid quantity of 165 cc ±1 cc. IFP depth is measured from the top edge of the body housing to the inside cup of the floating piston.

The XTRA rear track shock 7041387 has different specifications: an initial IFP depth of 5.25 inches and a fluid quantity of 108.2 cc ±0.25 cc.

PDF Search, Bookmarks, and Diagram Detail

Search and diagram detail: Most text pages have a searchable OCR layer, but diagram labels are only partly searchable, and the XTRA suspension exploded-view page has no searchable text. Chapter and subsection bookmarks are included, with an occasional offset in a subsection destination. Small wiring labels require zooming; some fine annotations remain blurred when enlarged.

The printable, English-language 657-page PDF contains 636 regularly numbered manual pages, 17 chapter contents pages, and four inserted Off Season Storage update pages. All contents and update pages are included in the stated total.
