Installation
Figure 6-16: Cross-Section of Cast Spoke Wheel
POM0116
NOTE: All 8.5-5 rims require special size hubs and spacer bands.
1. Place the inside rim (4) over the cast spoke wheel as far as possible.
2. Push the spacer band (1) over the cast spoke wheel with constant pressure on both sides. Guard against
cocking.
3. Place the outer dual rim (2) in position.

4. Align the valve locators between the spokes. Secure clamps (3) evenly in position. Snug up nuts in the sequence
shown. Do not tighten nuts fully.
5. After the nuts are properly seated and the rim is centered on the spoke wheel, tighten the nuts one-quarter turn
at a time in the criss-cross sequence until they are tightened to 200-260 ft-lbs. This will permit the rims to
properly align themselves on the 28° mounting surfaces of the cast spoke wheel.
6. If the heel of the rear clamp touches the spoke before reaching 80% of the recommended torque level, check
to be sure that the proper clamps and spacer bands are being used.
