Is it possible to remove a munci tail shaft housing with the tranny in the car? Just bought a new speedometer for my 35 Chevy. But it doesn't work because the speedo gear on the tail shaft has moved. Plastic gear, broken clip, just my luck. Thanks for any help.
I think so. You'd want to skip the steps about removing the side cover and front bearing retainer... but it's been several years since I worked on one, so my memory is foggy..
At least through 1970 I do not ever recall seeing a Muncie with a plastic gear and a metal retainer clip. All of the Muncies I ever had across had a press on speedo drive gear like the service manual pages that squirrel posted. Are you sure the drive gear is pressed on at the correct location? I was guilty of that the last time I put one together.
I think you can (Ive never tried it like that) but the reverse shaft and fork can be tricky to get back in place when they go back together. Ive used the plastic gear with the little metal retainer before too. They look funky but they work.
The last one I did with a plastic gear already had the hole. I think the later ones have the hole already, but Im not sure when they started that.
I've decided to do it in the car. If it doesn;t work out won't take much to remove the trans. Thanks for all your help. Paul
I finally got the parts and did this job this morning. I took the tranny out, I don't think you could do this in the car. There is a pin that holds the reverse shifting arm in place that has to be removed and a thrust washer that falls out of place when you remove the housing. Had to stand tranny up on end to keep the thrust washer in place when reinstalling the tailshaft housing. What I found was a steel speedo gear that was 1 inch away from where it should have been. Someone was most likely in this trans before and forgot to drive the gear all the way on. But anyway I now have a working and correct speedometer.
