OUTPUT REDUCTION UNIT (OUTPUT DRIVE) REPLACEMENT --
1. Clean screws (22) and mating surfaces of output reduction drive (19) and vehicle hull with dry--cleaning solvent.
Do not apply pressure sensitive tape when ambient tem-
perature is below 45°F (7.2° C). Failure to comply may
cause loss of screw torque and equipment damage.
2. Apply sealing compound to threads and under heads of screws (22). Apply sealing compound or pressure sensi-
tive tape to surfaces of output reduction drives and vehicle hull.
3. Install four new preformed packings (large O--rings) (30) in inner and middle grooves of both left and right side
transmission output housings (18).
To keep output drive balanced as it is being installed in
the vehicle, ensure sling assembly bracket is as close as
possible to open end of sling. Be careful when lifting out-
put drive to ensure output drive clears the hull. To avoid
failure of sling or suitable lifting device, do not force suit-
able lifting device to pull against weight of vehicle. Fail-
ure to comply may cause damage to equipment or injury
