2009 Yamaha G23-AG "UMAX MEDIUM DUTY I" (CARB) Service an...
The 2009 G23-AG is the last model year inside LIT-19616-G2-30, a manual that begins with the 2004 UMAX cars. Its code is G23AG and the engine is carbureted.
Nine variants share the volume, gas and 48-volt electric G23 UMAX Medium Duty models alike. For a late car that consolidated approach is an advantage, because component changes made during the run are recorded rather than left for you to discover.
Engine and fuel system work is given in full, with carburetor detail and the clearance tables for valves, cylinder and piston. The drive train chapter covers clutch and belt inspection to factory limits. Brake, rear axle, steering and suspension procedures carry torque figures and wear specifications.
Electrical diagnosis is supported by wiring diagrams drawn to the production harness. Quote both G23AG and the part number when you check a part fits this car.
