TM 9-2520-272-40 0067 Springs Look at springs for wear or breaks. If bad, discard springs. Retaining Rings (Snap Rings) Look at retaining rings for cracks, bends, burrs, or nicks. Remove burrs and nicks with whetstone. If rings are cracked or bent, discard rings. Snap rings must be tight in grooves. Threaded Parts 1. Inspect all threaded parts for stripped or damaged threads and burrs. 2. Replace all parts that have stripped threads or have damage which cannot be repaired by chasing the threads with a tap or die of the proper size, or by installing threaded inserts. END OF TASK LUBRICATION 1. Refer to Vehicle Lubrication Order LO 9-2350-277-13 (M113) for general lubrication information for the transmission. 2. When repairing, assembling, or installing transmission components, make sure all moving parts are well oiled with lubricating oil. This oil will protect parts during the f rst few moments after engine start-up. 3. Put lubricating oil on all moving parts, such as gears, shafts, and bearings. Also put oil on mating surfaces of valve bodies and housings that mate with moving parts. Put oil or petrolatum on all preformed packings, O-rings, seals, and seal rings as required in the task. Put oil on parts with hand oiler or dip parts in a container of clean oil. 4. Put high-temperature grease on the inside lip of all plain encased seals. 5. Use petrolatum when required to hold gaskets, thrust washers, bushings, or other parts in place during assembly. 6. The combined application of petrolatum and lubrication oil on journals makes bearings or races slide on and off the journals more easily. 7. Immerse all plates in clean lubricating oil one at a time before assembly. Keep all plates in the same order and facing the same way as when disassembled. Soak plates for a minimum of two minutes. 8. Soak each new friction-faced friction plate for a minimum of two minutes in clean lubricating oil. 9. Put lubricating oil on walls and hubs that seal rings will contact. NOTE New plugs with pre-coated threads, such as Tef on-coated threads, need no lubrication or sealant before they are installed. 10.Put a small amount of nonhardening sealing compound on the f rst three threads of all reused or uncoated external pipe plugs and hydraulic f ttings.
