Bill | | | | | Joined: Dec 2006 Posts: 97 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2006 Posts: 97 | Yes sorry about that that could be because the guy that did the motor could have not got it fully down ...what happen it got a knock in the motor that was thought to be a lose bolt on the flywheel so out comes the transmission (auto ) ever thing is okay so he pulls the motor and puts bearings in the bottom end and rings no more knock it runs good for hundred miles are so the takes out some teeth off the distributor ...one guy said the bushing had bound up ...but as i said you can turn the shaft with your hand ...so i am not sure what the cause was ,just put a new gear on and see what happen i guess ... | | | | | Joined: Feb 2006 Posts: 1,867 Shop Shark | | Shop Shark Joined: Feb 2006 Posts: 1,867 | Just curious, what engine are we talking about?

Inspect your old gear to see if the teeth are generally thinned---they won't usually be stripped all the way around.If they are thinned you will find the cam gear worn also and a new gear will likely not last very long.
On these engines the distributor not being all way down is NOT a very likely situation because the hold down clamp pulls it into mesh with the pump drive shaft.
Exactly the same as small block v-8
