spection cover bolts should be kept tight.
The axle flange to hub bolts on
%
and 1 ton trucks should
be kept properly tightened. If these bolts are found loose and
grease has worked out between hub and axle flange, new axle
shaft gaskets should be installed.
Fig. 49-Shaft to Hub Adjustment
On all 1%, 2 and 2% ton
trucks the axle shaft is spline
attached to the wheel hub
(fig. 49). External splines
on the outer diameter of the
shaft flange mesh with in-

shaft is retained in the hub
by a hub cap. Should leak-
age occur simply remove hub
cap, clean mating faces, in-
stall new gasket, replace hub
cap and tighten hub cap re-
taining bolts securely.
Rear Wheels and Bearings
Description. All models are equipped with demountable steel
disc wheels. They are held securely on the axle flange or hub
flange with special bolts and nuts. All models except the half
ton have the wheel hub mounted on the outer end of axle
housing with two large barrel type roller bearings. An adjust-
ing nut which screwS onto the end of axle housing provides a
means of adjusting the bear-

V2
ton semi-floating
axle has the wheel bolted di-
rectly to the axle f!tlnge. The
bearing is in the outer end
of the axle housing and rides
on a special race on the axle
shaft just back of the axle
