Quoted from jalpert:You have a part in that mech number 03-8090. Here is a pic of it:

Radical! uses the same part. The part had some grease on it from the factory, maybe try taking the mech apart cleaning and re-greasing the part. If this part is warn it's damn near impossible to find. I spent $80 on the last two I could find because I own Earthshaker and Radical!
You're probably okay though. Take the mech apart, new coil sleeve, inspect it, clean up and re-grease the flat cam, make sure all your switches are properly adjusted and take it from there.
There was someone in Europe who had it a bit ago. This part SCREAMS to be re-made, and someone was working on it a few years ago, but never heard what was happening.
I would love to have this made in Delrin for my ES. (Mine is also not working properly, but doesn't seem to be damaged.)
