The Tach on my 64 quit working the other day. I checked the cable, and it was OK. If I spin the drive cable, the tach seems to work (no binding). Then I took the drive gear assembly out of the distributor and found that the teeth were sheared off. The teeth on the distributor shaft were stripped also. I have purchased a new distributor shaft and tach drive assembly (with needle bearings). My question is... what is the lubrication requirement for the tach drive gear. The 63/64 shop manual does not cover this (nor does my new assembly).
