2011 Polaris Ranger RZR 800, RZR S & RZR 4 UTV Factory Service Manual (P/N 9923142)

This factory service manual covers the 2011 Polaris Ranger RZR 800, RZR S and RZR 4, including the listed EPS models and RZR S EPS INT'L configuration. Engine repair data applies to the RZR800HO-11 engine, designation 1204276.

• Engine repair: Engine removal, crankcase disassembly, cylinder-head and valve-seat reconditioning, hydraulic-lifter inspection, and reassembly procedures.

• Bosch M17 EFI: Fuel-pump replacement, injector and sensor tests, Throttle Position Sensor (TPS) calibration, trouble-code interpretation, and Digital Wrench™ operation.

• PVT and transmission: Drive and driven clutch service, clutch offset adjustment, belt inspection, and transfer-case and shift-housing disassembly and reassembly.

• Final drive: Centralized Hilliard front gearcase service, AWD coil testing, propshaft work, CV joint and boot replacement, and rear gearcase procedures.

• Steering and suspension: Electronic Power Steering (EPS) unit replacement, independent dual A-arm service, and FOX™ and Walker Evans™ shock rebuilding.

• Hydraulic brakes: Master-cylinder replacement, front and rear caliper overhaul, brake bleeding, pad replacement, and disc inspection.

• Electrical diagnosis: Starting and charging tests, starter-motor repair, EPS troubleshooting, wiring diagrams, and connector information.

This manual suits technicians familiar with internal engine work and electrical testing; its PVT maintenance and repair procedures specifically call for trained, certified Polaris Master Service Dealer technicians.

Engine, Lubrication and Cooling

Periodic maintenance schedules distinguish normal operation from severe use in mud, water, heavy loads, and short cold-weather trips. Fluid specifications, gearcase lubrication requirements, and compression and leakdown checks support routine service.

Engine teardown and reassembly cover crankcase splitting, valve-seat reconditioning, and hydraulic lifters. Cylinder-head bolt tightening sequences accompany tolerance charts for camshaft journals, valve stems, and piston fit. Crankcase Exploded Views and the Oil Flow Chart show component relationships and oil routing through the main gallery and camshaft bores.

Cooling coverage includes pressure testing, radiator removal, bleeding, and water-pump mechanical-seal replacement. The seal section identifies installer PA-44995 and warns that attempting seal replacement with the gear/stator housing attached can damage the shaft.

EFI Tests and Electrical Fault Tracing

The fuel-pump section combines pressure, supply-voltage, and continuity tests, helping distinguish a pump fault from a problem in its electrical supply before replacement. The pump's filters are replaced with the assembly.

Digital Wrench™ coverage extends to live data, fault codes, and ECU reprogramming. These functions require the diagnostic software and interface equipment; the documented reflash process also requires dealer authorization.

The Diagnostic Trouble Code Table relates SPN/FMI identifiers to Digital Wrench codes. An EPS System Breakout, Cooling System Break-Out Diagram, and Charging System Testing Flow Chart support circuit diagnosis alongside the wiring sheets.

Always observe workshop safety precautions, relieve EFI fuel pressure before disassembly, and securely support the vehicle during lifting and service.

Clutches, Transmission and Rear Gearcase Variants

Clutch inspection includes sheave bushings, shift weights, rollers, and spacer arrangements. Transmission procedures cover the transfer case and shift housing, with bearing inspection and reassembly checks.

Rear gearcase coverage separates the standard arrangement from the RZR S INT'L differential and its lock/unlock mechanism. Ring-and-pinion shimming is outside the documented repair scope; the manual specifies complete gearcase replacement for the listed gear or housing damage.

CV coverage includes joint inspection and joint/boot replacement. Complete internal CV-joint disassembly is discouraged because the matched components develop their own wear patterns.

EPS, Shock Rebuilding and Brake Variants

Separate EPS and non-EPS steering procedures identify an important damage risk: striking the steering wheel or shaft while connected to the EPS unit can permanently damage it.

Shock sections distinguish FOX™ Podium X units for the RZR S, FOX™ 2.0 piggyback units for the RZR 4, and Walker Evans™ reservoir shocks for the RZR L.E. Rebuild information includes valve-stack arrangements, floating-piston positioning, oil bleeding, and nitrogen charging.

Brake service distinguishes RZR 4 caliper components from the RZR/RZR S arrangements, with separate inspection dimensions and illustrated assemblies.

Sample Piston Clearance and Diagnostic Specifications

These examples are a small selection of the inspection and diagnostic specifications in the manual.

For the RZR800HO-11 engine, specified cylinder-to-piston clearance is 0.040 ± 0.015 mm. The EFI fuel-pump test lists normal pressure as 45 ± 2 psi with the pump activated by the key switch.

For an AWD engagement fault, the front gearcase coil resistance specification is 21.6–26.4 ohms.

PDF Text Search and Wiring Diagram Detail

Search, bookmarks and readability: Text sections are searchable, but some illustration labels and the appended wiring sheets are not. Embedded bookmarks lead to all ten chapters and the wiring appendix. Small wiring labels require zooming; overprinted text partially obscures some connection-table entries.

The download is one printable 406-page PDF in English. Its 396 chapter pages include five notes pages; the remaining ten pages contain wiring diagrams and connection tables.
