IH 504 Tachometer

Postby ajhbike » Sat Sep 12, 2020 6:08 pm

Back again on this darn tachometer. I have the right gauge and a cable. I took out the drive and the drive holder from the distributor drive housing. The nylon drive came out of the holder without any resistance and I didn't know any different. The long and short of it is that the cable keeps shifting the drive in the holder.

Looking at the drive there is a narrow part in the shaft and looking at the inside of the holder there is a slot around the inside. Is there supposed to be a snap ring or something internal to the holder to hold the drive in place?

see if you can see a snapring slot anywhere---I think there should be one to hold things together. I never had my 504 apart so dont know for positive.

I have since gotten the answer...Note the flat piece and I was able to get it at Steiner. Thanks
