These 3-gear transmission cases are specified as replacement parts for the YZ-2CA series. The package lists left and right housings made to mount into the standard 2WD off-road drivetrain while preserving the original gear arrangement and mounting points.
Compatibility is simple: the case conforms to the YZ-2CA gearbox layout and supports the B-YZ2CA chassis variant. Use this set to swap out worn housings and restore accurate drivetrain alignment at the chassis level.
During installation inspect for wear, confirm gear mesh and shaft seating, and manually rotate the drive train before powering. Reliable housing fit helps reduce play and extends usable life of the drivetrain components.
