paging distributor experts....lars?
http://forums.corvetteforum.com/show...highlight=tach
Follow up from this thread....
I got the new cross-drive gear from CC (271001). even called their parts support to ask them if with this set up the nylon button would still be needed. Person on other end (didnt get the name) said that no, this new gear eliminated the need for it.
I am not so sure...i got the part in, and the gear will pull out (but does spin freely
)
Here is the part I got....

but, since the gear will pull out, isnt the nylon button (this isnt the thrust washer you all are referring to is it?) there to prevent the gear from driving itself further into the housing? I think this is the hogging that Lars describes in the thread above.
Bottom line, I may still need the nylon button?
Second bottom line, how can I tell if the previous tach gear has hogged into the housing? I shoved my finger up there, and didnt feel anything obvious, but then again, I dont think I know what I was looking for. taking something to a lathe as Lars describes is definitely out of my ability range.
I'm gonna have to pull the distributor, ain't I? oh boy......

The needle bearing cross gear & bushing does not compensate for the wear on the inside of the distributor housing caused by the thrust load of the crossgear. If your old cross gear has worn a counterbore into the inside of the housing, you MUST repair this before installing a new gear. The nylon thrust washers will not fit into the hogged-out area caused by the old cross gear, so the nylon part will not solve your problem if you have the wear.

Thanks Lars - that is what I was thinking.....but I can't really tell (at least by looking and feeling) whether a counterbore has ever happened. Would it be really noticable?
Thanks again....
Thanks again....

You should be able to pull the crossgear bushing out of the distributor housing (the big round brass threaded part) and then stick you finger into the hole in the distributor housing. Jam your finger into te back wall of the dstributor and dig through the grease. You should be able to feel any counterbore and damage to the housing with your fingertip.
But if I were you, I'd just yank the distributor out, swab out the area with a rag, and do a good visual inspection. It'll take you 2 minutes to pull it out and 3 minutes to stick it back in, so just yank it.

You don't know me very well.....it will easily take me 2 hours to do such a simple task.
