a.

Inspect midship winch for tight mounting and

broken or missing parts. Tighten loose parts. Repair or

replace missing or damaged parts as necessary

(para. 13-12).

Check drive chain (1) for proper tension and damage.

To check and adjust tension, using a straight edge as a

gage, measure 7/16-9/16 in (1.1- 1.4 cm) deflection at

upper midpoint of drive chain (1). If deflection is not

correct, record measurement and adjust drive chain (1).

1. Loosen two locknuts (3) on sleeve bearing (2).

2. Slide sleeve bearing (2) right or left in slotted holes

on support bracket (4) to tighten or loosen drive chain (1).

3. Repeat steps 1 and 2.

4. Tighten two locknuts (3) when proper deflection is

obtained.

Replace drive chain (1) if damaged (para. 13-13).
