Title: Changing front sprocket.
Post by: JoeSchmoe on July 27, 2011, 07:15:00 AM

Hello folks! My neighbor stripped out the chain/sprockets on his 350 Raptor.

He's having trouble with the nut holding the front (little) sprocket. Not coming off.

Before he REALLY whales on it he'd like to know if it is regular thread or reverse thread?

I haven't worked on a 350 before but I imagine it should be the same principle as a 700s...make sure the locktab is bent off and use an air impact or breaker bar on it (best to do it with the trans in neutral) and put the parking brake on, wedge the rear sprocket and/or rotor and use a breaker bar.

Wow, thanks for the quick response!

Do you remember if it was reverse threaded?

It's done! He ended up wrapping the back of the sprocket with a wet rag, heating it with his torch, loosening the nut, and pouring water on it to cool it down.

He's one happy camper. Maybe one day he'll join the 90s and get a computer   :rolleyes:

Heat's not good for any seals that might be behind it, but glad to know he got it fixed...
