ABSTRACT:
A small vehicle features a drive system that directs power from an engine unit to at least one driven wheel. The driven wheel is connected to a half shaft. The half shaft is driven by a ring gear. The ring gear is driven by a pinion gear. The pinion gear is connected to a longitudinally extending drive shaft. The pinion gear is axially adjustable along the rotational axis of the drive shaft relative to the ring gear. The pinion gear is not substantially axially adjustable relative to a cover member the partially defines a gear housing. The cover member is adjustably secured to the balance of the gear housing through a shim. The shim can be exchanged for varied shim sizes to effect proper meshing between the pinion gear and the ring gear.
