Thread: Muncie 4 spd speedo drive

Tweet

So I'm within a week or so of getting the '32 running and I went to install the drive for the electic speedo on the Muncie 4 speed. I put the little adapter pin into the plastic tranny gear and gave it a spin - and it spun! Obviously it should not have, so I removed the speedo driven gear assy and low and behold - the drive gear on the output shaft is too far in on the shaft. Pulling the motor and trans now is a major setback. I think I can get the output housing off with the tranny in place - do you think I will be able to do that and pull the gear back 1/2" or so? It was a swap meet tranny that checked out good, but I never thought to look at the alignment of the speedo gears. Bummer.

There are two reverse gear thrust washers that will fall out of place on the idler shaft not fun to line up out ot the car it can be done in the car but there will be a lot of swearing and bitchin in the garage that day good luck.

The tranny is now out of the car and the tailhousing off - and it appears that the speedo drive gear is in the correct spot on the output shaft. If I pull it out 1/2" to match the driven gear, it looks like the shaft is a smaller diameter at that point. Any idea what gives? I will be calling some transmission shops in the morning, but don't have high hopes for finding any experts here in the Olympia area.

New 32,
Call Ray Wallace @ Race World in Olympia.

Denny - my case and tailhousing numbers indicate its a late '65, with the speedo drive on the RH side. I was aware of the different gear od's, but the problem is that the machined area on the shaft appears to be 1/2" closer to the trans than it should be. I don't see on any lists where there is more than one 27 spline tailshaft. I'm taking it to a Lacey shop in the AM that said they have a Muncie "expert". Maybe the gear can be moved back a little without "falling off" of the machined part of the shaft. We'll see.

Jim - I don't see a Race World in the Oly phone book at hand. There is a Ray Wallace on S. Bay Rd. and I think I know where his shop is - an engine builder, right? I'll check it out.

Thanks, guys.

That's the one, he's one of the best for rears and gears. I'd tell you to bring it in to me but I'm so swamped it isn't funny.

Well, apparently the speedo drive is the least of my problems - shop says the entire tranny except the case and cluster is toast. I saw the damage so know they aren't BS'ing me. Now looking at a rebuilt exchange for $900+ shpg, w/ warranty. So much for swap meet trannys that look okay, and I'm not exactly new at this either. Guess I should have been more critical. Bummer. Embarassing and expensive bummer.

Jim - I met with Ray Wallace tonight and am taking him the trans tomorrow to see if he can salvage it. Thanks for the tip.
