2009–2014 Suzuki LT-A500XP KingQuad Owner's Manual (P/N 99500-44080-03E, 99011-31H60-03A)

• Service-manual coverage: 2009-model Suzuki LT-A500XPK9 and LT-A500XPZK9 KingQuad ATVs for Sweden (P-17), Australia (P-24), Canada (P-28), and the U.S. (P-33), starting at effective frame number 5SAAM45P97100001.
• Document set: two PDFs totaling 772 pages - Factory Service Manual P/N 99500-44080-03E with 624 pages, plus the LT-A500XP K9 Owner's Manual P/N 99011-31H60-03A with 148 pages.
• Engine repair runs from EFI/SDS fault isolation and ECM terminal checks through engine removal, top- and bottom-end disassembly, cylinder-head work, crankshaft inspection, lubrication diagnosis, cooling-system service, and fuel-pressure testing.
• Drivetrain sections document CVT engagement and lock-up diagnosis, V-belt and movable drive/driven face service, clutch repair, transfer and gearshift work, drive-shaft service, differential/final-drive overhaul, tooth-contact checks, and shim selection.
• Chassis procedures cover double-wishbone suspension, hubs, knuckles, bearings and bushings, hydraulic front brakes, the sealed oil-bathed rear brake, parking brake, steering shaft and tie rods, plus EPS self-diagnosis.
• Operator-side coverage explains instrument-panel functions, L-H-N-R range selection, 2WD/4WD/differential-lock operation, break-in, hills and side slopes, obstacles, water crossings, cold-weather use, cargo and towing, storage, and scheduled maintenance.

Exact Model and Publication Scope

The service publication identifies the covered vehicles as the 2009 LT-A500XP and LT-A500XPZ K9 variants; the companion owner's manual is labeled LT-A500XP K9. Its country-code table separates Swedish, Australian, Canadian, and U.S. configurations for warning labels, horn and reversing-light equipment, and market-specific main wiring diagrams. Both are Suzuki Motor Corporation publications: the service manual is dated December 2008 and the owner's manual September 2008.

Engine, EFI, and Electrical Diagnosis

Engine coverage goes beyond routine maintenance. It documents engine removal and installation, top- and bottom-end disassembly and assembly, camshaft and cam-chain inspection, and piston and cylinder checks. Cylinder-head work covers disassembly, valve-guide replacement, and valve-seat repair. Lower-engine and support-system sections address crankshaft inspection, bearings, oil seals, the oil pump, water pump, starter, and charging system.

EFI diagnosis is organized by circuit and trouble code. Coverage includes CKP, throttle-position, coolant-temperature, injector, idle-speed-control, fuel-pump-relay, and differential-lock-relay faults. Diagnostic work is tied to the mode selection switch 09930-82720 and the SUZUKI Diagnostic System set 09904-41010 with CD-ROM 99565-01010-019, covering DTC checks, "Show Data When Trouble," sampled operating data, reset procedures, and code deletion.

Drivetrain and Chassis Repair

The CVT chapter addresses the V-belt transmission, movable drive and driven faces, clutch shoe, clutch cover, cooling duct, engagement and lock-up checks, shift lever assembly, and shift-rod adjustment. It identifies tools such as the clutch spring compressor 09922-31430 and fixed driven face holder 09924-52450.

Separate driveline chapters cover front and rear shafts, the 2WD/4WD/differential-lock system, transfer and gearshift cam, front differential, final gear case, output and propeller shafts, backlash measurement, gear-tooth contact, and shim adjustment. Suspension and brake repair includes shock and spring-preload work, control arms, wheel hubs, knuckles, bearings, rear stabilizer, front brake bleeding, master-cylinder and caliper service, rear wet multi-disc brake disassembly, and parking-brake adjustment.

Steering content combines shaft and tie-rod service with EPS fail-safe operation, torque-sensor and motor-circuit DTCs, control-unit removal, and EPS motor inspection. Body chapters cover fenders, seat, under covers, footrests, carriers, front grip bar, and trailer-towing hardware. Factory cautions define repair limits: the EPS control unit/body assembly and the wheel-side front drive-shaft joint are treated as non-disassemblable units. Prolonged clutch lock-up testing is identified as a damage risk to the clutch and engine.

Operational and Maintenance Guidelines

The Owner's Manual covers the instrument panel, shift and selection switches, starting, braking, turning, skidding, hill climbing and descending, traversing slopes, obstacles, shallow-water operation, cold-weather riding, reverse use, loading, winch lead wires, trailer towing, transport, cleaning, storage, and return to service.

Routine maintenance covers the battery, spark plug, throttle and fuel controls, engine oil and filter, air cleaner, coolant, driveline oils, tires, brakes, wheel removal, spark arrester, drive-shaft boots, lighting, fuses, and lubrication points. Owner-level troubleshooting is limited to fuel-supply and ignition checks; the service manual supplies the shop-level diagnosis and repair procedures.

Specification and Diagram Reference

Representative factory references include the FI System Wiring Diagram, Engine Lubrication Circuit Diagram, Cooling Circuit Diagram, Front Drive (Differential) Construction, Gearshift System Construction, and EPS Wiring Diagram. Main wiring sheets are provided for P-17 and P-24/28/33. The set also contains ECM terminal alignment, component-location views, harness, cable, and hose routing, DTC and fail-safe charts, exploded assembly views, service-data tables, component-specific torque tables, pressure-test data, capacities, clearances, wear limits, and adjustment specifications.

The service manual is written for technicians with mechanical knowledge, equipment, and special tools. Incorrect repair of the fuel, brake, CVT, engine, steering, or electrical systems can leave the ATV unsafe.
