(45)
, a Teflon washer if
needed

, and a flat washer
(44)
.
4. Test that the sheave turns freely with axial play within 0.005" to 0.010". Lateral offset
between the two sheaves should not exceed 0.032".
Note If play is excessive, add shims
(45)
to remove play.
5. Attach the end of the tape over the sheave pin
(28)
and while wearing gloves, wind the tape
onto the sheave assembly
(18)
as an assistant provides some tension on the tape to keep it
