Put in a new main shaft and Waa laaa success...whoever needed the part number let me know!!

I replaced my cross gear and the cable is rotating, but the tach still sits at zero. Any ideas for me to check? Is there a gear in the back of the tach that could be broke/stripped?

I replaced my Main shaft you can get a high horsepower main shaft and shim kit for about 45 bucks from the last detail.......took about 10 minutes to do and the tach is working perfect :cheers:

I had the tach in the '62 re-built in New Stanton, Pa. last Spring; it didn't work at all the whole summer of '00 after I had the ZZ4 installed. Saw an "opp" on rte. 376 (6 lane/3 each way) between Churchill and Monroeville to watch it go "roundy-round"...nothing in front of me, nothing behind; "kicked it" and was smooth sailing to 120mph. Then the wind musta caught under the windshield wipers, and they "popped up" (note to self: stash clean underwear somewhere in trunk for occasions like this ;) )

What did you shim yours too?

Thanks Alwyn678,
I ordered one from The Last Detail, this evening.

Yes I did shim it ...it was a bit loose...This distributor in my car was from a 67 vette a believe....a high hp car..So it the guts of the distributor were toast..But it is not that hard to install the shim kit at all
