2008 Yamaha G23-AF "UMAX MEDIUM DUTY I" (CARB) Service and Repair Manual

2008 G23-AF UMAX Medium Duty I

Part number LIT-19616-G2-30, model code G23AF, carbureted. Confirm the code before ordering; the UMAX line ran in close variants.

Yamaha's coverage here spans 2004 to 2009 and nine models, both the gas and the 48-volt electric G23 UMAX cars. One manual, six seasons, with the revisions noted in the text where they occurred.

The book opens with specifications and the maintenance schedule, then works through the engine and carburetor with their clearance figures, the fuel system, clutch and drive train, brake and parking brake adjustment, rear axle, steering, front suspension, wheels, frame and body. The electrical chapter closes it with full wiring diagrams and test values.

For a working utility car the adjustment and inspection procedures are the heart of it, since knowing the factory wear limit is what tells you whether a part goes back on or into the bin.
