Polaris Predator 500 / Troy Lee Designs 2005 ATV Service Manual (P/N 9919514)

This is the Polaris factory 2005 Predator 500 Service Manual, P/N 9919514, covering the standard A05GJ50AA and Troy Lee Designs A05GJ50AB. It contains shop-level repair and diagnostic procedures for the Fuji DOHC four-stroke engine and the ATV's supporting systems.

Searchable Service Text and Wiring Detail

Text search, bookmarks, and diagrams: Service text is searchable, with embedded bookmarks for chapters, procedures, and the index. The wiring-diagram labels and wire-termination table are not text-searchable; their small details are clear when enlarged.

One printable English-language PDF contains 213 pages, including both covers, a safety/trademark page, a chapter index, a four-page subject index, three notes pages, and a one-page feedback form.

Engine, FOX Suspension, and Electrical Service

These coverage highlights outline selected work rather than the full contents. Other topics include spark-arrestor cleaning and decal replacement.

• Engine and transmission repair: Step-by-step procedures for engine removal, DOHC top-end service, crankcase separation, clutch and shifter work, transmission disassembly, cam timing, and reassembly.

• Carburetor and fuel pump: Mikuni BSR 42 teardown, cleaning, inspection, float adjustment, needle-and-seat leakage checks, fuel-level testing, pump service, and jetting guidance.

• Lubrication and cooling: Oil-pressure testing, oil-flow diagnosis, oil-pump inspection and priming, radiator-cap and cooling-system pressure tests, bleeding, and water-pump seal replacement.

• Steering and chassis: Front-hub and steering-knuckle repair, ball-joint replacement, A-arm service, concentric swingarm removal, rear-axle runout checks, and axle disassembly and installation.

• FOX shock rebuilding: Separate standard and TLD Podium X procedures cover disassembly, seal replacement, valving, bleeding, internal floating piston setup, and nitrogen charging.

• Hydraulic brakes: Fluid replacement and bleeding, master-cylinder removal and installation, front and rear pad/disc service, caliper rebuilding, wear inspection, and troubleshooting.

• Electrical diagnosis: Ignition timing, DC/CDI and stator tests, charging checks, fan and switch tests, starter-motor repair, troubleshooting flowcharts, and factory wiring documentation.

Suited to experienced ATV mechanics and advanced owners with precision measuring tools, pullers, a hydraulic press, and appropriate shock-service equipment; Polaris directs users unfamiliar with safe service procedures, and certain marked operations, to a qualified dealer.

Standard and Troy Lee Designs Configurations

The factory specification pages distinguish intermediate transmission ratios, engine-oil capacities, rear wheel/tire sizing, carburetor needles and initial pilot-screw settings, and shock packages. The standard model uses FOX shocks with a remote-reservoir rear unit; TLD uses Podium X shocks with piggyback front and remote rear reservoirs.

Model-number, VIN, and engine-serial-location references help identify the machine before repair data or parts are selected.

Engine Access, Inspection, and Reassembly

In-frame versus engine-out work: Flywheel, stator, starter-drive, and water-pump mechanical-seal service are identified as accessible with the engine installed. Cylinder-head, piston, crankshaft, and internal transmission work require engine removal.

Top-end inspection includes camshaft journals, cylinder-head warpage, valve-clearance pad selection, piston/cylinder measurement, honing, and valve-guide/seat reconditioning. Bottom-end coverage includes oil-pump clearances, crankcase bearings, transmission shafts and gears, and water-pump shaft and seals.

Crankshaft scope: Inspection and straightening are covered; rebuilding the pressed crankshaft assembly is referred to separate crankshaft-rebuilding and parts manuals. Incorrect camshaft-to-crankshaft timing can cause serious engine damage.

Fuel-System Diagnosis and Routine Maintenance

The CV-carburetor explanation connects its operating circuits with lean/rich and erratic-idle troubleshooting. Needle and needle-jet wear checks address mixture faults; the manual reserves pilot-circuit cleaning for a certified repair shop.

Periodic schedules and lubrication charts accompany oil/filter service, coolant checks, compression testing, toe alignment, drive-chain adjustment, brake inspection, and suspension settings.

Shock Precautions and Diagnostic References

The shock chapters explain that pressure washing can damage seals, while a damper shaft spinning in its holding clamps can suffer permanent damage and cause leakage. FOX service involves high-pressure nitrogen; the manual requires pressure release before disassembly.

Named illustrations: The ES50PL Oil Flow Chart and Predator Cam Timing Exploded View support engine work. Other references include the Mikuni BSR 42 Carburetor Exploded View, Rear Swing Arm/Axle Exploded View, Starter System Testing Flow Chart, and two-page 2005 Predator wiring documentation, including its wire-termination table.

Ignition and charging flowcharts link test results to the next diagnostic check, helping distinguish circuit faults from component faults before replacement.

Tools and reference data: Callouts include the PA-46087 crankcase separator, PA-46075 flywheel puller, and PA-45958 cam-chain tensioner tool. Other specified equipment includes the 2872105 water-pump seal puller, 2200421 shock recharging kit, and PV-43568 digital multimeter.

Component torque tables, valve-adjusting-pad matrices, shock-valving data, jetting charts, wear limits, and electrical test specifications accompany the procedures.

A Preview of Oil-Pressure and Piston-Fit Specifications

Hot-engine lubrication: The oil-pressure test specifies 20 PSI as standard and 12 PSI minimum at 5500 RPM using Polaris PS-4 Synthetic oil.

Piston fit: ES50PL service data list standard piston-to-cylinder clearance of .0018–.0025 in. (.046–.065 mm), with a .0039 in. (.10 mm) service limit. These entries distinguish standard fit from the wear limit used during inspection.
