The Rear Axle Disc is used during rear axle differential setup to establish the correct pinion shim height. The disc provides a reference surface that helps position the pinion accurately before final assembly. Correct shim height supports proper gear contact between the pinion and ring gear. Accurate positioning helps achieve smooth power flow through the axle assembly. Proper use of the disc supports reliable differential operation during equipment movement.Attributes:• Supports smooth engagement between pinion and ring gear.• Helps control gear wear through accurate alignment.• Supports consistent differential setup procedures.Applications: The Rear Axle Disc is positioned in the rear axle differential during setup, where it helps set correct pinion shim height to achieve proper gear alignment and smooth power transfer up.
