Refer to VehicIe Lubrication Order, LO 9-1450-300-12 (M730A2) or LO 9-2350-277-12
(M113A3), for general lubrication information for the transmission
When repairing, assembling, or installing transmission components, make sure all moving parts
are well oiled with lubricating oil (Item 10, Appendix C).
This oil will protect parts during the
first few moments after engine start-up.
Put lubricating oil (Item 10, Appendix C) 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 (Item 10 or 14, Appendix C) 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.
Put high-temperature grease (Item 9, Appendix C) on the inside lip of all plain encased seals.
Use petrolatum (Item 14 Appendix C) when required to hold gaskets, thrust washers, bushings,
or other parts in place during assembly.
The combined application of petrolatum (Item 14, Appendix C) and lubricating oil (Item 10,
Appendix C) on journals makes bearings or races slide on and off the journals more easily.
Immerse all used disks and plates in clean lubricating oil (Item 10, Appendix C) one at a time
before assembly. Keep all plates and disks in the same order and facing the same way as when
disassembled. Soak plates and disks for a minimum of two minutes.
Soak each new friction-faced disk for a minimum of two minutes in clean lubricating oil
(Item 10, Appendix C).
Put lubricating oil (Item 10, Appendix C) on walls and hubs that seal rings will contact.
New plugs with precoated threads, such as Teflon-coated threads, need no
lubrication or sealant before they are installed.
Put a small amount of nonhardening sealing compound (Item 17, Appendix C) on the first three
threads of all reused or uncoated external pipe plugs and hydraulic fittings.
