Section VI - Clamp Ring Replacement and Reassembly
1. Inspect the clamp ring. If clamp ring requires replacement, it is recommended to remove the plastic foot (item 15)
first. NOTE: 100/112 frame B5 adapters do not use the foot. See figures 32 and 33. Remove the four (4) M6 bolts
(items 28 and 28A).

2. Remove the five (5) M8 bolts, lock washers and flat washers (items 34, 33, and 32) from the clamp ring (item
12B). See figure 34. Remove the clamp ring from the motor adapter. There is a snug fit between the clamp ring
and motor adapter due to the vapor protection o-ring (item 12C). Carefully pull the two parts apart. See figure 35.

3. Inspect the motor adapter o-ring (item 12C). Replace if damaged. If it is re-

M8 bolts, lock washers and flat washers (items 34, 33 and 32) and tighten in a
star pattern to 130 in-lbs. (14.7 N-m). See figure 39.
