Additional information
This transmission sprocket, part number 786061, engages the drive chain to transfer power through the gearbox and maintain proper rotational speed to driven components. Correct sprocket engagement helps support smooth drivetrain operation and reduces wear on the chain and mating gears.
If the drivetrain slips under load, makes unusual noise, or the chain skips on the sprocket teeth, the transmission sprocket may be worn or damaged. Hooked teeth, uneven wear, or visible deformation can also indicate a problem that affects performance.
Before starting the repair, disconnect the spark plug wire or power source to prevent accidental starting. Relieve chain tension before removing the old sprocket, then install the new transmission sprocket and confirm proper chain alignment and tension before use.
