IMPORTANT INFORMATION !
For Laminated Tire and Wheels:
FIGURE 2
Wheel Hub Dis-Assembly:
Important Note: There are two types of hubs (figure 3 &
4) that have been used, these are best Identified by the
seal type. The earlier type has a one piece seal (figure 3).
The later type has a three piece seal (seal, inner seal
adapter and outer seal protector). If the hub you are
working on has a one piece seal it must be re-assembled
using the components of the one piece seal hub. If it is a
three piece seal
(figure 4) it must use components for
three piece seal hub. The parts for the two different hubs
will not interchange. Check which you have before ordering
parts. See figure 3 & 4 for items reference in dis-assembly
steps.
NOTE: Axle Spindles shown removed from axle as
illustration only, the spindles are actually welded to the
axle arms and are not removable.
1. Before removing the wheel from the hub ( item 1)
make note of which way lug nuts are installed. The
laminated tire lug nut MUST be installed different than the
other wheels.
(see previous page if using laminated tires
and wheels)
2. Clean all dirt and debris from dust cap and hub before
attempting to remove dust cap. Use a small wedge type
tool to dislodge the dust cap
( item 2) from the hub, dust
cap will pry off usually with ease.
3. Remove the cotter pin ( item 3). It will require the
cotter pin be un-bent to remove it, dis-card the old cotter
pin and replace it with new one during re-assembly.
4 Remove the slotted retaining nut (item 4) from the
spindle (it has RH threads). Slide the retaining nut washer
( item 5) off axle spindle shaft.
