Assembly Breakdowns and Workshop Utility
Finding the exact replacement component shouldn't stall your shop's workflow. This 100-page OEM reference streamlines the ordering process by providing original part numbers directly alongside detailed exploded views. You can immediately see how the cylinder head, crankshaft-piston group, and camshaft-chain drive fit together. Grab the instant download, open the file on your shop tablet, and accurately match what is on your lift to the factory diagrams. The catalog also covers carburetor components, exhaust parts, crankcase covers, fender assemblies, and the complete electrical harness, including CDI unit identification.
Technical Specifications and Part Identification
Getting the specs right the first time prevents costly re-orders. This manual provides critical identification data, listing the NGK D7EA spark plug as the factory standard. Transmission data is equally precise, breaking down internal gears like the 1st through 5th wheels and their corresponding pinions. It also specifies exact thickness values for shims used in the middle drive gear and rear axle gear case.
Always secure the ATV and disconnect the battery before removing any covers or starting disassembly to maintain a safe working environment. Please note that this document is strictly an identification and ordering reference, not a step-by-step diagnostic guide. To better navigate these technical schematics, reviewing how factory workshop documentation is structured can help optimize your parts sourcing process.
