2009 Polaris Ranger RZR 170 UTV Service Manual (P/N 9922134)

This Polaris service manual, P/N 9922134, covers the 2009 Ranger RZR 170 (R09VA17AA), with maintenance, mechanical repair and electrical diagnosis for the carbureted youth model.

• Engine repair: Engine removal, top-end and bottom-end disassembly, valve-seat reconditioning, cylinder inspection, camshaft timing and crankcase reassembly.

• CVT and transmission: Drive-belt replacement, drive and driven clutch service, internal gear inspection, output-shaft housing service and pinion-depth adjustment.

• Brakes: Hydraulic bleeding, pad and disc replacement, parking-brake cable service, caliper replacement and master-cylinder replacement.

• Chassis and steering: Front A-arm replacement, hub bearing and seal service, rear swing-arm and axle work, steering-shaft removal and gearbox replacement.

• Fuel-system maintenance: Air-filter service, choke and throttle cable adjustment, carburetor idle and pilot-air-screw adjustment, and fuel-filter and line inspection.

• Electrical troubleshooting: ETC switch adjustment, ignition and charging tests, starter-system diagnosis, circuit diagrams and component test specifications.

This manual suits technicians equipped for precision engine measurement and electrical testing; Polaris specifies trained Master Service Dealer technicians for CVT maintenance and repair.

Engine Disassembly and Reassembly

Technical sections cover the S35C engine, identified as ES35C in the engine service tables. Cylinder-head work includes rocker and camshaft inspection, valve-guide measurements, valve-seat reconditioning and sealing tests.

Bottom-end coverage includes crankcase separation, bearing inspection, balance-shaft installation and oil-pump replacement. The crankshaft and oil pump are treated as replacement assemblies. The Oil Flow Diagram and breather/oil-separator coverage explain the lubrication and crankcase ventilation layout.

Camshaft timing is documented with the stator housing installed or removed, using separate reference illustrations for each configuration.

The compression-test warning identifies cylinder-head damage from an overlong tester adapter. A separate disassembly note identifies the crankshaft slotted nut’s left-hand thread, helping prevent thread damage from forcing it in the wrong direction.

CVT, Transmission and Chassis Service

Clutch inspection covers roller tracks, sheave faces, driven-spring condition and centrifugal friction shoes. Overheating and water-ingestion diagnostics address the CVT air ducts and housing seals.

Transmission work extends to shift-fork and shift-drum inspection, gear engagement surfaces and output gear pinion-depth shimming. The shimming procedure sets pinion depth only; backlash adjustment is not provided.

Chassis procedures include steering-shaft and gearbox removal, tie-rod replacement, A-arm pivots, rear swing-arm service and axle-housing bearing replacement. Cab Frame Exploded Views identify assembly hardware and spacer relationships.

Working on off-road vehicles involves inherent safety risks; always ensure the machine is properly supported on jack stands and the battery is disconnected before initiating any major mechanical or electrical repairs.

Brake Service and Replacement Limits

The brake chapter covers master-cylinder and caliper bleeding, parking-brake adjustment, cable replacement and pad burnishing. Troubleshooting addresses brake noise, pedal vibration, dragging calipers and brake lockup.

Calipers and the master cylinder are specified for replacement as complete assemblies.

Fuel Maintenance and Electrical Diagnosis

Keihin carburetor maintenance includes idle and pilot-air-screw adjustment, supported by fuel-filter, fuel-line and cable procedures. The Jetting Chart and Clutch Chart provide altitude-related reference data.

Fuel-section limit: The separately referenced Chapter 4 fuel-system section is absent from this PDF; the included maintenance pages do not provide a complete carburetor overhaul chapter.

Electrical coverage includes battery care, stator/alternator testing and CDI output testing with a peak-reading adapter, identified as PV-39991. Starter coverage includes disassembly, testing and cleaning, with assembly replacement where required.

The Transmission Switch – Circuit Breakout and ignition-limiter explanations help distinguish gear-position or ETC inputs from ignition-component faults. Ignition, charging and starter test charts support fault tracing through the related wiring and components.

Selected Cylinder-Head and Piston-Ring Inspection Data

These are a few examples of the engine inspection specifications included in the manual. The cylinder-head surface warpage limit is 0.002 in. (0.05 mm).

For the top piston ring, the standard installed end gap is 0.0059–0.013 in. (0.15–0.35 mm), with a service limit of 0.0196 in. (0.5 mm). The engine section supplies the corresponding measurement procedure and separate data for the other rings.

Text Search, Section Bookmarks and Wiring Detail

Search and diagram access: Service text supports keyword searches, and embedded bookmarks open the included sections and wiring sheet. The landscape wiring sheet uses light lines; its small circuit labels are readable with zooming but are not searchable.

The download contains one printable, 187-page English PDF, including the Notes page and the final landscape wiring sheet.
