B. Inspect housing for cracks, loose studs, nicks, and burrs at machined surfaces. Remove nicks and burrs with
stone or file. Make all necessary repairs or parts replacement before installing drive unit in housing.
C. Install new drive unit to housing gasket over housing studs.
Roll carrier into position on roller jack. Start carrier into housing with four flat washers and nuts equally spaced.
Do not drive carrier into housing with a hammer at the carrier stud flange.
The flange may easily be distorted and cause severe oil leakage.
Install lock washers and stud nuts on any studs under carrier housing offsets. It is impossible to start these nuts
after carrier is drawn into housing.
Tighten the four nuts over flat washers alternately to draw carrier squarely into axle housing.
Remove nuts and flat washers. Install taper dowels, lock washers and stud nuts. Tighten to the correct torque.
Connect universal at pinion shaft.
Install axle shafts.
Preparation for Storage.
In the event the carrier is a spare and may not be immediately installed, all gears and bearings should be thoroughly
oiled and the carrier placed in a dustproof container.
Proper lubrication of the drive units is extremely important. Our "Standard" recommended lubricant is Rockwell-Standard
Specification 0-65, S.A.E. 140 viscosity, multipurpose gear lubricant. Unusual operating conditions such as extremes in
climatic temperatures may require lubricants of "Optional" viscosities. Refer to Field Maintenance Manual No. 1,
"Lubrication," for detailed information.
Since Rockwell-Standard lubricant specifications are periodically revised, always refer to Field Maintenance Manual No.
1 for current complete lubricant specifications and applications.
New and Reconditioned Axle Service.
The original rear axle lubricant should be drained at the end of the drive-away or before the maximum of 3,000 miles
prior to placing the vehicle in regular service. Drain the lubricant initially used in the assembly following reconditioning at
the same interval. Completely drain the lubricant while the unit is warm.
Fill axle housings to bottom of level hole with specified lubricant with the vehicle level. Put an additional 2 U.S. pints of
specified lubricant in the interaxle differential housing.
