Reassemble Rotator Assembly
1. Rinse the top fixed plate and gear plate assembly with fresh water. Do not clean
the plates with an abrasive cleaner. The surface of the top fixed plate must remain
smooth to correctly seal.
2. Reattach the gear plate assembly to the top fixed plate by aligning the center holes
and tightening the bolts (position the bolts in the threaded holes and tighten only
until the lock washer is flat).
3. Manually rotate the gear plate assembly so that the unthreaded alignment hole
matches up with the hole in the top fixed plate.

Perform a Leak Test
After parts are replaced and the rotator is reassembled, a leak test should be performed to
ensure that the rotator assembly is properly sealed. To perform a leak test, complete the steps
shown next.
1. Confirm that the rotator assembly fill plug is in place before beginning the leak
test.
2. Place the rotator assembly in a sink or wet area.
