tor equipped with limit switches, continue with the
instructions below.
27. Apply two or three drops of Loc-Tite No. 35 Extra
Strength Retaining Ring Compound to the shell
bore.
If a new (replacement) limit switch adapter is being in-

motor mounting holes in the housing flange.
29. Spot drill the adapter (29) in two places and install
the two half dog point set screws (30). Proceed
directly to step 32.
30. Install the limit switch adapter (29) in the shell, align-
ing the spot drilled holes in the adapter with the
tapped holes in the shell.
31. Install the two half dog point set screws (30).
