Thanks for all the tips. 😉
I read the service manual on replacing the spring. So if I understand it correctly,
1. Cut and remove the old rope,
2. Carefully replace the coiled spring, greasing as I go. Can I assume white lithium grease? It looks like that was originally used.
3. Reassemble the pulley to the housing making sure each end of the spring inserted into their corresponding pins.
4. Wind the spring tight, then back off until the rope hole/slot lines up.
5. Insert a pin to keep spring from uncoiling.
6. Install rope and tie a knot in the end.
7. Remove the pin and slowly allow the spring to coil the rope back into the housing. Assuming the rope is the correct length, the "J" mark should be close to lining up on the housing.
I’m sure I’m making this sound more difficult than it actually is. 😉
