The Genuine Buddy 125 gearbox diagram shows the complete final drive transmission assembly, including the transmission cover, drive shaft, axle, idle gear, final drive gear, brake shoe pivot, oil seals, bearings, retaining rings, and related mounting hardware. This diagram is used to identify OEM replacement parts for rear wheel drive service, gearbox repairs, and final drive maintenance.
The gearbox is responsible for transferring power from the CVT system to the rear wheel, reducing engine speed while increasing torque for usable road performance. It also integrates the rear brake shoe pivot system and seals that maintain proper lubrication within the final drive housing.
Common repairs include replacing worn axle or drive shaft bearings that cause noise or wheel play, servicing leaking oil seals that lead to gear oil loss, repairing stripped or damaged transmission covers, and rebuilding the final drive assembly after internal gear wear or failure.
