Topic: Tach gauge

[Johnny340]

I've been having trouble getting my tach to work.  A new drive gear somehow broke the housing that holds it onto the cylinder head cover.  Anyway, when I try to drive the Tach with a drill on the cable, the gauge is very sluggish to move.  The cable is free to move though.  Any suggestions on fixing that gauge or is it toast?

Rebuild your tach.

Just a follow up to anyone searching this problem in the future.

My tach works perfectly now!
That speedometer link was good as were a few YouTube videos to show how simple these tachs are.  Mine had been previously molested by a PO which is what caused the main problem.  One of the small screws that holds the face plate on was rattling around inside the glass.  That wasn't a big deal but the other one was silver...which meant the other black one went missing the last time the tach was apart.  It was on the magnet!  I removed that (and put it back where it belonged) lubed the main pivot and after spinning it a bit, it was smooth as new.  Plus it looked mint too with both black screws back in place.
