VI. STEERABLE DRIVE END ASSEMBLY
Wheel Hub Assembly
Assemble the wheel bearing cups and the outer
axle shaft drive studs to the wheel hub.
On disc style wheel hubs:
Press wheel studs into place. Left thread
studs go into the left hand hub, right hand thread
studs into the right hub.
On cast spoke style hubs:
Assemble the brake drum to the cast spoke
hub and secure with bolts, washers, and nuts.
Tighten bolts to correct torque. Install the rim
studs to cast spoke hub.
Pack the inner wheel bearing cone with the
proper lubricant and insert into the wheel hub.
Coat the outside circumference of the wheel hub
seal with liquid sealant and press into the hub.
Pack the cavity between the inner and outer
wheel bearing to level of the small diameter of
the bearing cups.
On disc style drum:
Adjust the brakes to match closely, but still
clear the brake drum.
On cast spoke hubs:
Adjust the brakes to match the brake drum
Measure the I.D. of the drum and adjust the
brakes to match the gauge reading. The gauge
is available from the McMaster-Carr Supply Co.,
Position the wheel hub or cast spoke hub and
drum carefully over the spindle, brake and
spindle yoke assembly. (See fig. 17). Rotate
the hub while positioning over spindle.
Pack the outer wheel bearing and install over the
Install the wheel bearing adjusting nut with
dowel, if used, dowel facing outward (or up).
(See fig. 16).
10. Adjust the wheel bearings per III-B.
Outer Drive Yoke and Outer Drive Axle Shaft
The outer drive yoke should be complete with a
bearing race pressed on its hub. This race
should not have been removed at disassembly
unless either the yoke or race were replaced by
Lubricate the seal and bearing surface of the
outer drive yoke and put the yoke in place in the
bearing and seal that is in spindle yoke. (See
Apply a bead of liquid sealant to the outer axle
shaft flange. See Service Bulletin 738 407, Page
Install the yoke spacer ring onto the outer axle
shaft splines. Insert the shaft into the spindle
bore, rotate and align the splines with the drive
yoke splines, rotate the shaft and yoke to align
the flange holes with the drive studs. (See fig.
38). Insert the long (2 inch) yoke retaining bolt
through a new sealing washer, through the
retaining washer and into the threaded hole in
the shaft end. (See fig. 39). Tighten to specified
Push axially on the outer drive yoke and check
for positive clearance under the axle shaft
flange. The clearance should be at least .015-
inch. (See fig. 40).
Install the locknuts to retain the axle shaft.
Tighten to specified torque.
On oil lubricated wheel bearing, turn wheel hub
to position the oil plug hole in the outer axle shaft
horizontally. (See fig. 41). Fill hub with specified
oil, install plug.
Install the hub cap.
