349 sprocket removal

Featured Replies

Hi, I'm trying to remove the front sprocket off my 1981 349. I can't get my 3 legged puller on and trying to remove the curved bracket that goes around the sprocket. I've taken the bolt off that holds the chain tensioner on but when trying to undo the top nut the whole thing is turning and won't undo. I'm concerned as to what is at the back of the threaded part as it goes into the case and I don't know if it's undoing something inside. I'll attach a pic when I can resize it correctly.

Cheers

Neil

Managed to cut a slot in with a multi tool and got the nut off by using a screwdriver in the slot.I can't get the stud out as I would like to at least clean it up put it just turns....

Got a puller behind the sprocket and put tension on it.Given it plenty of thumps wit a hammer and will leave it overnight I suppose.

You will probably need a hydraulic puller

Cheers,

A friend made me a puller to remove the primary drive sprocket when I changed the crank seals. I'll ask if he can make an adaptor for that...

An angle grinder with a 100mm disc will work - I know because that's what I did, and didn't have to take that chain guard off either. The sprocket will pop loose when the disc gets close to the shaft
