1998–2002 Suzuki King Quad 300 LT-F300/LT-F300F Service Manual (P/N 99500-42133-01E)

This Suzuki factory service manual, P/N 99500-42133-01E, Fourth Edition (September 2001), is a 384-page PDF covering inspection, service, and overhaul of the LT-F300 and LT-F300F. Suzuki states that it is written for people with the knowledge, skills, equipment, and special tools needed to service its vehicles; generally known information is omitted. It is suited to experienced mechanics working in a properly equipped shop, not beginners learning basic repair practice. Each later-model section records only changes; unchanged procedures remain in preceding sections.

• Model coverage: 1999 LT-F300X/LT-F300FX, 2000 LT-F300Y/LT-F300FY, 2001 LT-F300K1/LT-F300FK1, and 2002 LT-F300FK2. LT-F300 is 2WD, LT-F300F is 4WD, and 2002 coverage is F-model only.
• Engine repair: Covers engine removal and installation, disassembly and reassembly, cylinder-head and valve service, cam timing, piston and crankshaft work, oil-pump inspection, and recoil-starter service.
• Clutch and transmission work: Details the centrifugal clutch, wet multi-plate clutch pack, starter clutch, gearshift mechanism, constant-mesh transmission, reverse system, and the two-range or three-range sub-transmission, with engagement and lock-up tests.
• LT-F300F driveline service: Provides secondary bevel-gear, front differential, propeller-shaft, front-drive-shaft, and rear-axle procedures, including bearing work, shim selection, backlash checks, tooth-contact inspection, and final adjustment.
• Chassis and brake procedures: Covers wheels and tires, steering, toe-in adjustment, front and rear suspension, hydraulic front brakes, mechanical rear brakes, master-cylinder service, fluid replacement, and brake bleeding; the 2002 section adds front disc-brake repair.
• Fuel and electrical diagnosis: Documents fuel-tank, valve, pump, and carburetor work along with charging, starter, CDI ignition, relay, switch, lighting, battery, and regional wiring-system troubleshooting.

Engine and Multi-Range Drivetrain

The 280cc air-cooled OHC single is documented from removal through teardown, inspection, repair, and final adjustment. Service-data tables group factory standards and wear limits for the rocker arms, valves and guides, camshaft journals, cylinder and piston, piston rings, connecting rod, crankshaft, clutch, oil pump, gearshift forks, and transmission shafts. Exploded assembly views pair component identification with torque, lubrication, sealant, and thread-lock callouts.

The transmission material distinguishes the LT-F300 two-range sub-transmission from the LT-F300F Super Low, Low, and High arrangement. Clutch coverage goes beyond cable adjustment, with initial engagement and lock-up inspections plus internal checks for the plates, shoes, wheel, release mechanism, and one-way clutch. The special-tool section identifies the crankshaft installer 09910-32812, valve-guide remover/installer 09916-44910, clutch-sleeve-hub holder 09920-53730, and multi-circuit tester set 09900-25008. Suzuki warns that striking the crankshaft into the crankcase can disturb its alignment; the specified installer is required.

Four-Wheel Drive, Chassis, and Brake Work

The LT-F300F-only shaft-drive chapter carries repair through secondary bevel-gear and front-differential removal, disassembly, inspection, reassembly, and remounting. It supplies shim charts, bearing-preload data, gear backlash and clearance specifications, and tooth-contact patterns. After tooth-contact correction, backlash must be checked again; an incorrect setup can leave the matched drive and driven gears improperly meshed.

Chassis coverage separates the hydraulic front drum brake and mechanical rear drum brake used on earlier models from the hydraulic front disc system documented for the 2002 LT-F300FK2. That section covers pads, calipers, discs, master cylinder, brake-fluid replacement, revised front-suspension work, front-brake hose routing, and related tightening and inspection data. Approved-fluid information specifies DOT 4 glycol-based brake fluid and SAE 90 GL-5 hypoid differential oil for the LT-F300F, with an SAE 80 cold-weather alternative.

Fuel, Electrical, and Model-Year Updates

The base 1999 specification uses the Mikuni BST31SS carburetor. The 2000 supplement changes to the BSR29SS and supplies disassembly, cleaning, inspection, float adjustment, remounting, and hose-routing information; the 2001 and 2002 service data carry that carburetor forward. Lubrication coverage extends to the oil cooler, oil-temperature or cooling-fan thermo-switch, pressure testing, and the lubrication-system chart.

Electrical chapters explain charging, starting, and CDI ignition operation, followed by fault isolation for the generator, regulator/rectifier, starter motor and relays, ignition coil, pickup coil, and CDI unit. Separate tests cover switches, lamps, the cooling-fan diode, and battery. The 2002 supplement adds its ignition/starter control relay and revised regulator/rectifier and CDI checks.

Diagram examples include the Lubrication System Chart, transmission cross-sectional view, LT-F300F differential construction and tooth-contact views, starter-system circuit, CDI ignition-system circuit, and model-year/market-specific wiring diagrams. Harness, control-cable, fuel, oil-cooler, brake, and breather-hose routing views support correct installation.

Regional specifications and wiring distinguish E-03 USA, E-17 Sweden, E-24 Australia, E-27 New Zealand, E-28 Canada, and E-33 California applications where applicable. Consolidated service data covers torque specifications, fluid capacities, adjustment data, electrical test values, and standard-versus-limit dimensions. Because it addresses hydraulic brakes, a spring-loaded recoil starter, and loaded clutch tests, the precautions and specified equipment should be followed; Suzuki warns that improper repair can leave the vehicle unsafe.
