Figure 11 – Setting End Clearance
1. Loosen the two setscrews on the outer bearing cap.
2. Slowly and evenly tighten the 2 hex head bolts on the outer bearing cap. This will slowly move
the rotor towards the cover. Continue this until the rotor contacts the cover. This can be
determined by rotating the rotor by hand. Once you feel the drag between the rotor and cover,
stop. This is zero end clearance.
3. Measure the distance between the outer bearing cap and the bearing carrier. Use appropriate
feeler gages or gage blocks. Record this dimension and then remove the feeler gages or gage
blocks. Note the position on the outer bearing cap where the dimension was taken.
4. Loosen the two hex head bolts on the outer bearing cap.
5. Slowly and evenly tighten the two setscrews on the outer bearing cap until there is a gap
slightly larger than the distance measured in step 3 above.
6. Determine the proper end clearance (refer to Table 5) and add that dimension to the dimension
measured in step 3 above. Prepare feeler gages or gage blocks for the total dimension and
insert between the outer bearing cap and the bearing carrier in the same position that the
original dimension (step 3) was taken.
7. Start backing off the two setscrews equally. This will move the rotor towards the cover.
Continue this until tension is felt on the feeler gages or gage blocks.
8. Once the proper end clearance has been obtained, remove the feeler gages or gage blocks
and tighten the two hex head bolts.
