Read section carefully before at­tempting replacement.

1. Keep trap at on bench. Remove

with coupler. If shaft moves freely
continue assembly. If shaft binds,
loosen bolts and turn shaft until
shaft rotates freely. Retighten
bolts. Shaft should be concentric
with shaft hole when viewed from
backside. (FIG. 10)

3. Replace gasket (FIG. 8) and re­install oil cover to trap. (FIG. 4)

4. Remove setscrews on coupler.

Coat setscrew threads with

ush with coupler. Coupler should

be approximately 1/8" off trap
surface. (FIG. 11)
