Thrust faces of transmission and final drive planetary carriers can be damaged by foreign material or by the failure of a washer. This guideline covers two recommended procedures that can be used to repair damaged faces of planetary carriers for transmissions and planetary carriers for final drives. A semi-finished spacer can be used if welding alters the dimension of the spacer. After the welding process, the spacer can be machined to the correct dimension. A finished spacer may also be used to repair the thrust face. If you repair the thrust face with a finished spacer, complete precision machining and positioning before you weld the spacer in place.This guideline contains the latest standards of engineering, which will help minimize owning and operating costs. A part can be expected to reach the next Planned Component Repair if the part meets the specifications in this guideline and if the part is used in the same application.Do not operate or perform any lubrication, maintenance, or repair on this product until you have understood the operation, lubrication, maintenance, and repair information. If a part has met the specification in this guideline, the part can be expected to give normal performance until the next overhaul. The conditions apply when the part is used in the same application.If this guideline shows a part that is not reusable, do not install the part. During reconditioning, correct any conditions that might have caused the original failure.
