Speedo at T-case stuck

I have 79 cj5 w/304 3 spd./Dana 20 and I have isolated my problem with no mph readings lies in the speedo at the t-case. My problem is I need to check the speedo in the t-case, but the PO ( Previous Owner) stripped the speedo itself where you attach a 7/8 thin wall socket on it to remove it. I have tried everything except heat. Any suggestions?

If I cant get it off can I remove the tail section of it or will that ruin the speedo gear on the shaft and the speedo itself??

Thanks for any help,
Steve

I don't have any idea about trying to take the Tcase apart to get to the speedo gear. I know it is tight getting in there, but you might try a chisel and hammer?

I'm trying to figure out what you mean by the "OP stripped the speedo itself" part.

What's stripped? The cable won't come off of the gear housing that threads into the case or the hex head of the housing is stripped?

PO not OP. Previous Owner. I put what I meant in parenthesis. Sorry for the confusion.
The cable comes out, but I can not take the 7/8 hex head out of the tail shaft. I even ground down a socket to fit on it deeper and still it wont come off. I am stumped. I was debating to just take off the tail shaft to try to get it out that way, but I think it wont come off without getting the speedo out first.

I knew what you meant by OP. My confusion was calling everything the speedo. That's the gauge in the dash.

Does the hex head (speedo gear housing) turn? I guess that's what you mean by the speedo is stripped.

Yes it is stripped. I read a few articles and the Speedo is what they called it. Again sorry to confuse anybody.

If it were me I'd use a pipe wrench.

There's no way to get a pipe wrench on it. It's recessed.

Yes, you can remove the entire rear output housing as a unit and it will not mess up anything. Not sure how that will help though, unless it will give you more room to "wrench".

I would be taking a small cold chisel or screwdriver and hammer and try to tap on what is left of the hex corners to back it off or at least get it started that way.,

Are the threads stripped or are the corners rounded off so that a socket won't grab it?

In your case the part you are trying to remove may have become sacrificial. As for removing the tail piece I do believe that the speedo stuff has to come out first as the speedo gears are engaged internally.. Go to Morris 4X4 and look at the parts breakdown. So far the chisel method seems like the best idea.


I'd start looking at finding a replacement part.

Edit: Thinking back I believe the biggest issue I had was getting the socket on the flats. As I recall I had an old 7/8" sheet metal socket tool used or spark plug removal on my dirt bike. So you may need to take a 7/8" deep and grind the outside down to fit.. At least I think it was 7/8".

And not just grind down the outside, I found i had to grind the top down. There was a little area at the tip of the socket where the edge is kind of beveled and wasn't grabbing the hex head. Does that make sense? I'll post a picture of what I mean when I get home.
