Friction ring disintegrated, causing unplanned bail closures. Also, while taking apart reel, didn\'t realize I lost the anti-reverse cam spring.

1. Took rotor, anti-reverse, and lower reel body off per YouTube description.
2. With photo of where the ant-reverse cam spring went, I \"figured out\" how it was configured and, with some nimble pressing with a small flat-head screwdriver, got it in place.
3. BE CAREFUL: if you don\'t keep tension on the anti-reverse selec tor, the cam spring WILL shoot out and become lost in shag carpet --(found it!)
4. Once the back of the reel was put together, took a Phillips head and removed the white plastic bail trip to install the friction ring with the rounded side out.
5. Note: friction ring looked too small for the Shimano Stradic 4000 FE but was right size.
6. Reel works great and bail doesn\'t trip suddenly, sending my lures to a watery grave.

Saltwater did a number on my reel over the last fall surf fishing run. I did a complete tear down of every part and replaced anything that was necessary

The hardest spring to get in place is the anti reverse spring, IGÇÖm not sure if some special tool would have helped but eventually I was able to get it in place with a pai r of needle nose and keep the cam switch locked in place with tape so it wouldnGÇÖt move while I adjusted the spring in place.
