1066 tach RR

I got that tach out and fixed I think. I actually have not started it yet. It was a booger to get out. Everything Allen in Neb said to do but in addition I had to unhook tach cable at front of engine and slide it backwards about 2 inches to get enough room for my hand to get cable unscrewed off back of tach. I was able after about 2 hours of tedious, nerve racking prying to un-crimp chrome ring to get it off the case. Cleaned off dust from tach face and back side of lens and re-installed and re-crimped. It can be done!!!

yeah. Just like I told you. Be sure and test before you buttone it totally up. Your needle could hang on that gasket.

How did you un-crimp and re-crimp that ring?

Thanks,

I used a 5/16 flat screw driver(a new one with good square corners) and only forced one corner of the blade under the crimp holding the screwdriver at about a 30 degree angle to the tach face. I started at the little notch on crimp on back side and gave it a twist to open up the crimp just a little bit and did that about every 1/4 inch all the way around and went around it 3 times. I didn't stand the crimp up but left it about 1/4 over as I figured it would be hard to crimp back if I completely opened it up. I used two really small(about 1/8 inch) flat screw drivers and worked the ring over the rolled lip on the tach case. I was lucky that I didn't even nick that little tiny paper gasket. Hardest thing going back was working that ring back over the lip on the case. To start the crimp folding back down I used a slip lock pliers and wrapped 4 or 5 wraps electrical tape around bottom jaw to keep it from scratching chrome ring face. Held tach upside down, placed taped jaw on front face of chrome ring just past the edge and other jaw on crimp back side and while squeezing pulled upward on plier handles. Went around it twice before I had the crimp almost back tight. The third time around was with a vise grip to squeeze the crimp tight. I was happy that you can't even see tool marks on that chrome ring unless you look really hard.
