2002 Yamaha G21-AX "YAMAHAULER" (CARB) Service and Repair...
Part number LIT-19616-G2-1A is the factory service manual for the 2002 Yamahauler, a car listed under the code G21AX.
Yamaha wrote it as a single reference for the 2001 to 2004 Yamahauler cars, so the G21-AW, G21-AY and G21-AZ appear here too. Check your frame plate against G21AX before you order parts, since the code, not the badge, is what the parts sections key from.
The manual works through the car in the order a shop does. Specifications and maintenance schedules open it, then engine and fuel system service, the drive train, brake system, steering and front end, frame and bodywork, and finally electrical with diagrams that show the actual harness rather than a generic layout.
For a working car that hauls tools or turf supplies, most of the value sits in the adjustment and inspection procedures, which tell you what to measure and what the factory considers worn out.
