CFMoto CF500-3 UTV Service & Repair Manual 2013 (first edition)

• 250-page CFMOTO service manual for the CF500-3/UTV, identified by the LCELDTZ VIN prefix and CF188-A engine-number prefix.
• Covers engine removal and internal repair work on the cylinder head, valve train, camshaft and timing chain, piston and cylinder, crankshaft, balancer shaft, oil pump, water pump, starter drive, and sealing surfaces.
• Details CVT and drivetrain repair, including primary and secondary sheaves, drive belt, centrifugal clutch, L-H-N-R transmission components, shift cam and forks, bevel gears, front output shaft, and front/rear axle setup.
• Includes MIKUNI BSR36-89 carburetor disassembly and adjustment, cooling- and lubrication-system testing, brake and steering checks, suspension service, and charging/ignition fault isolation.
• Provides CFMOTO special-tool charts with tool numbers, component-specific torque tables, service limits, cable-routing photos, exploded assembly views, troubleshooting charts, and full circuit and wiring diagrams.

Technical Documentation Coverage

This manual is written for the CF500-3/UTV with the CF188-A single-cylinder, liquid-cooled, four-valve SOHC engine. The fuel system shown is the MIKUNI BSR36-89 vacuum-diaphragm carburetor, not an EFI system. Driveline coverage is for the automatic CVT and wet centrifugal clutch with parking plus manual L-H-N-R range selection. Those identifiers are the key match points for this publication.

The 15-chapter layout moves from vehicle identification, maintenance data, service tools, lubricants, and cable routing into body-panel and muffler removal, periodic checks, cooling and lubrication work, engine removal, engine overhaul, carburetor service, chassis repair, axle work, and electrical diagnosis. The PDF also covers the dump box, roll-over bar, seats and belts, skid plates, fuel tank, winch cable and motor, dashboard, lighting, and visible body components rather than limiting the content to the powertrain.

Engine coverage goes well beyond tune-up data. It documents cylinder-head and rocker-arm disassembly, valve and seat inspection, camshaft and automatic-decompression checks, timing-chain service, cylinder and piston measurement, piston-ring and pin inspection, crankshaft and connecting-rod checks, balancer-shaft indexing, oil-pump and relief-valve inspection, crankcase separation, and final assembly. Procedures are also provided for the recoil and electric starting systems, magneto rotor, water pump, CVT housing, clutch, sheaves, belt, internal transmission shafts, reverse chain, shift cam, forks, and bevel gears.

The manual identifies dedicated service equipment rather than relying only on generic tool descriptions. Examples include the CF188-051000-922-001 CVT wrench, CF188-011300-922-001 oil-filter wrench, CF188-040004-922-002 piston-pin remover, CF188-022006-922-001 valve-spring compressor, and CF188-060008-922-001 limiting-nut wrench for the front output shaft.

Chassis chapters cover front and rear wheels, hydraulic disc brakes, master-cylinder handling, brake pads and discs, steering-stem and tie-rod checks, toe-in adjustment, shock absorbers, suspension arms, steering knuckles, wheel hubs, and constant-velocity drive shafts. The axle sections include differential, drive-pinion, and ring-gear disassembly; bearing and seal inspection; front-axle gear-motor checks; washer selection; and backlash measurement. The internal bevel-gear procedures add contact-pattern verification and readjustment when cases, gears, or covers are replaced. That is the level of information needed for axle repair, not just routine fluid service.

Electrical coverage includes the permanent-magnet 3-phase AC charging system, battery charging and leakage tests, regulator/rectifier diagnosis, AC magneto output checks, CDI ignition and peak-voltage testing, pickup and ignition coils, starter motor and relays, switches, horn, dashboard, fuel sender, and water-temperature transducer. The circuit section separates starter/ignition, charging/lighting, 2WD-4WD differential-lock, and signal circuits, followed by a full vehicle wiring diagram with component and wire-color identification.

Specification and Diagnostic Reference

Reference tables include scheduled service intervals, component torque specifications, approved lubricants and sealants, fluid capacities, engine and transmission clearances, wear limits, clutch test data, carburetor float and fuel-level settings, cooling-system pressure and temperature checks, axle backlash and shim data, and electrical resistance and voltage test values. Troubleshooting is organized around no-start and hard-start complaints, unstable idle, loss of high-speed power, overheating, abnormal engine or CVT noise, charging faults, brake performance, steering problems, and front/rear axle noise.

Illustrated references include the Cables, Pipes, Cable Routing photo layouts, Coolant System Chart, Engine Oil Cooling and Lubricating System Illustration, Primary and Secondary Sheave exploded view, Transmission exploded view, and the two-page Circuit Diagram / Wiring Diagram section. These views help identify routing, component order, connector locations, oil and coolant flow, and internal assembly relationships before repair work begins.

Several assembly cautions are specific to this machine. The secondary sheave ring nut must not be removed until the spring compressor is installed, because the loaded sheave can release abruptly. CVT belt and sheave contact surfaces must stay free of grease or oil, and the timing chain must be supported during top-end work so it cannot drop into or become trapped in the crankcase. When crankcase or bevel-gear components are replaced, the manual calls for washer readjustment and another backlash/contact check; incorrect setup can accelerate gear wear or binding.

Gasoline vapor, hot coolant, brake fluid, battery electrolyte, ignition voltage, rotating CVT parts, and a raised vehicle all require proper ventilation, electrical isolation, cool-down and pressure-release procedures, and secure lifting support. Follow the manual's safety cautions and use the specified tools before heavy repair work.
