WARNING
Use extreme caution when handling the spring.
The spring (25)
, which is located behind the flange
(26), is always under great tension and could be
propelled from the lower flange with enough force
to cause serious injury. Refer to Fig. 18.
To reduce the risk of serious injury when doing any
repair work that exposes you to the spring, be sure
to carefully follow the instructions below. Be sure
you understand this procedure before continuing
with the repair work.
12. Remove the screws (13) and nuts (9) from the reel
flanges (26 and 40). See Fig. 18.
13. Lay the reel flat. With extreme caution, lift up on
the flange (26) to expose the spring (25).
14. Carefully inspect the spring.
If either end of the spring (25) is worn or damaged
and does not hook properly on the reel hub (24) or
the pin (C), the spring needs to be replaced. See
Fig. 18. If the pin itself is broken, the lower reel
flange (40) must be replaced.
15. To remove the spring, use locking pliers (A) placed
near the end of the spring, as shown, to compress
several rows of the spring (25) together, and lift out
the spring. See Fig. 18.
16. Before disposing of the spring, carefully attach a
minimum of two hose clamps (B) around the
keeper (D) and spring (25) bands as shown in Fig.
19.
17. When greasing and installing the new spring, use a
locking pliers (A) to compress several rows of the
spring (25) together.
See Fig. 18.
Coat the new spring and the flange (40) with a
multi-purpose, lithium-based grease before
installing the spring.
