2005 Yamaha G22-EB "G-MAX" (48V - DC MOTOR) Service and R...
LIT-19616-22-04 documents the 2005 G22-EB G-MAX, a 48-volt DC motor car whose identification code is G22EB.
The same manual carries the 2003 to 2007 model years and fifteen variants, the gas G-MAX cars and the G23 UMAX Medium Duty utility models among them. Yamaha wrote the platform up once and noted the differences as they arose, which is why this part number appears against so many listings.
For an electric car the useful chapters are the battery and charging system, the controller and solenoid tests with expected values, and the motor section covering removal, brush inspection and reassembly. Full wiring diagrams back all of it.
The rest is conventional chassis work done to factory figures: brake adjustment, rear axle service, steering, suspension and body panels. If you have been working from guesswork on shoe thickness or brake free play, the printed limits will settle it.
