Polaris Sportsman 800 EFI / X2 700 EFI / Touring 800 EFI – 2008 ATV Manual Set (P/N 9921323)

The service manual provides repair procedures, while the separate illustrated parts catalog supports component identification for the earlier models listed in its publication row.

Parts-catalog scope: The catalog is for replacement-parts reference, not assembly instructions. Its model coverage differs from the service manual; it is not a 2008 parts catalog.

PDF Search, Bookmarks and Wiring Detail

Search and diagram navigation: Both PDFs have searchable text. The service manual includes chapter bookmarks and more detailed navigation within the clutch and final-drive sections; the parts catalog has no PDF bookmarks. Some circuit drawings and wire-termination tables contain image-based labels that are outside text search. Small wiring labels in the checked diagrams are readable when enlarged.

The ZIP download contains two printable English PDFs totaling 444 pages. This total includes six notes pages, two maintenance-record pages and one intentional blank in the service manual, plus the parts catalog’s front and rear covers, contents page and change-record page.

Engine, EFI and Drivetrain Service

The following are selected contents, rather than a complete table of contents. Other included topics cover maintenance schedules, lubrication charts and exhaust-system service.

• Engine and cooling: Engine removal and installation, crankcase disassembly, cylinder-head and valve service, piston and cylinder inspection, honing, camshaft inspection, pressure testing and coolant bleeding.

• Bosch EFI diagnostics: Fuel-pump and regulator testing, injector and sensor service, blink-code diagnosis, circuit checks and throttle-position-sensor initialization.

• PVT clutch repair: EBS drive- and driven-clutch inspection, disassembly, bushing service and reassembly, with belt inspection, clutch alignment and offset checks.

• Transmission overhaul: Gear-selector checks, transmission removal, internal teardown, inspection and reassembly, plus front-output-shaft backlash adjustment for the X2/Touring design.

• Final drive and ADC: CV-joint and boot service, gearcase diagnosis, Centralized Hilliard Active Descent Control hydraulic bleeding, piston replacement and ring-gear backlash adjustment.

• Chassis and brakes: Body and rack removal, steering and A-arm repair, strut service, X2 cargo-box and seat assemblies, hydraulic-brake bleeding and caliper service.

• Electrical troubleshooting: Instrument-cluster diagnostics, charging and ignition tests, starter-circuit diagnosis, starter-motor overhaul and model-specific wiring diagrams.

Its overhaul depth is suited to experienced technicians and advanced owners with the required measuring and service equipment; Polaris specifically reserves PVT maintenance and repair for trained, certified Master Service Dealer technicians.

Engine and Transmission Differences

The engine chapter distinguishes the EH068OLE and EH076OLE builds and identifies which components can be serviced in the chassis and which require engine removal. Supporting data covers fastener torque patterns, inspection limits, clearances, lubrication requirements, oil-flow routing and cooling-system specifications.

Step-by-step procedures cover internal engine work and transmission overhaul. Separate Sportsman and X2/Touring transmission sections help you select the appropriate teardown and setup procedure before working on the drivetrain.

EFI Tests, Tools and Repair Limits

Listed equipment includes the PU-43506 fuel-pressure kit with PU-47476 test valve, PU-47082 TPS harness and PU-47471 Digital Wrench SmartLink kit. Digital Wrench diagnostics require dealer-only software and interface hardware.

The fuel-pump and regulator tests support fuel-delivery diagnosis, but the pump/tank assembly and regulator are treated as non-serviceable assemblies. The ADC piston-pump assembly is also replaced as an assembly rather than internally rebuilt.

Disconnecting the ECU or component harnesses with the ignition on can send a damaging voltage spike through the ECU. The clutch is a precision-balanced assembly; mixing used components from another clutch can disturb that balance.

Other procedure-specific tools include the 2872292 EBS clutch alignment tool, PA-48542 ADC piston installation tool and 2871695 X2/Touring transmission backlash tool.

Chassis Variants and Electrical References

X2 and Touring differences extend through rear suspension, torsion-bar arrangements, bodywork, passenger-seat hardware, rear braking, differential-solenoid and speed-sensor systems. The dedicated International chapter illustrates the Touring model’s integrated four-wheel hydraulic brakes, steering-post lock assembly and turn/hazard-signal circuit.

Electrical diagnosis includes eight numbered speedometer fault tests, ADC and AWD coil checks, cooling-fan control, gear-position and electronic-throttle-control switches. Circuit-specific checks help distinguish wiring and connection faults from component failures before replacement.

Named visual references include the Oil/Water Pump and Timing Cover exploded view, EFI System exploded view, EBS-versus-non-EBS Drive Clutch views, ADC Gearcase exploded view and Charging System Testing Flow Chart.

Full wiring diagrams cover the Sportsman 800 EFI, 700 X2/800 Touring EFI, 800 Touring EFI International and Sportsman ADC circuits.

Related Publications and Safe Service

The service manual’s publications table references Owner’s Manual P/Ns 9921169 and 9921356, and Parts Manual P/Ns 9921349, 9921357 and 9921359. These are related publications, separate from the PDFs included here.

Because the set covers a pressurized EFI fuel system, hydraulic brakes and rotating PVT components, follow the manual’s safety warnings and specified service procedures before disassembly.

A Preview of EFI Diagnostic Values

For the covered Bosch EFI system, the fuel-pump test specifies normal pressure of 39 ± 3 psi with the ignition switched on to activate the pump. The procedure uses a pressure tester and fuel-rail adapter to assess fuel delivery.

The crankshaft-position-sensor test specifies 560 Ω ± 10% at 68°F (20°C). Resistance checks at the sensor and through the harness support diagnosis of the sensor circuit.
