INSTALLATION
CAUTION
There is a limit to which gaging material will compress, thus resulting in a false measurement.
If 0.12 inch (3.0 mm) material crushes to below 0.05 inch (1.3 mm), remeasure using
0.06 inch (1.5 mm) material.
NOTE
If using new parts, before installing cap and capscrews, place one piece of either
0.12 inch(3.0 mm) or 0.06 inch x 2.00 inch (1.5 x 50.8 mm) gaging material across end of
spud. Install cap and capscrews and evenly torque until no end play is felt in bearing, and
slight resistance is felt in bearing rotation. Remove capscrew, cap and gaging material.
Measure, using a micrometer, to find proper shim pack equal to or up to 0.002 inch (0.05 mm)
thicker than measurement.
1.
Pack bearings with grease.
2.
Install two cups (Figure 1, Item 5) and one cone (Figure 2, Item 6) into housing assembly (Figure 1, Item 7).
3.
Install housing assembly (Figure 1, Item 7) onto spud (Figure 1, Item 8).
4.
Install one cone (Figure 1, Item 6) onto spud (Figure 2, Item 8).
5.
Apply sealant compound on threads of two capscrews (Figure 1, Item 1).
