New, to me, M20
 
I bought this M20 on Marketplace in Roseville, MI. Very nice inside and a smoking deal. Tony was just there and picked it up for me.
Can't figure out how to post the pic or rotate it.

THANK YOU TONY !!!!!

How's this?

Too Many Projects 10-24-2023 02:44 AM

Wow, super enlarged too, thanks !

scuncio 10-24-2023 02:47 AM

Probably the nicest used Muncie internals I have seen. Face teeth and synchros look awesome.

Seems it may have been rebuilt at some point, but there are still a number of factory paint dabs too. From the pics, I think the input will need replaced due to rust. What is your opinion Tony ? Still for the cost, I can afford to do some updating and still be ahead. It's out of a '69 Corvette, by the partial vin.

Wow, that looks really nice!

Show me a picture of the rust. I might be able to help.

I can't do anything with the splined area, but I could fix the pilot bushing area.

Too Many Projects 10-24-2023 06:14 PM

Thanks, Freddie. We can maybe look at it in person at MCACN. Tony is bringing it there. Crash may have something better too. He's bringing a replacement tailhousing for me.

The new input shafts are not holding up very well, so either repairing yours or finding a good original replacement would be my choices. There are 2 ways that I could make it work. I can put it in a cylindrical grinder and grind it down past the rust and then make a new custom pilot bushing for it, or cut it down and weld it, then grind it to the original diameter.

Too Many Projects 10-24-2023 08:14 PM

I'm with ya there. I will be contacting Eric about a nice, original one. If you doesn't have anything, cutting it down some and an oversize bushing sounds good. I should shoot him a PM right now and see where this is going.

Too Many Projects 10-24-2023 08:49 PM

I forgot, he doesn't PM. Had to go look him up and email.

Maybe I'm not seeing the picture correctly but the rust on the input shaft doesn't look like it would be an issue to me. Have you run any sand paper on the pilot bushing area? A wire brush on the splines?

Not in my possession to look at it. Scuncio picked it up and we'll meet at MCACN next month. It may be savable, I'm just trying to see what's available if I need to replace it.

scuncio 10-25-2023 03:50 AM

Mitch, I can try cleaning it up if you'd like.

You've already done me a huge favor. If you want to putz with it a little, Tony, that would be great. Give me a better idea if it needs replaced/repaired.

I finally got to look at this trans today and clean up the input and bearing retainer. They both had rust on them, but came amazingly clean. I used my crud thug with a medium wire and finished with 400 sand paper. There is super light pitting, but nothing that will be an issue to just use as is. The inside is amazing as well. The outside appears to have long term use, but it must have been behind a stock L48 that just didn't get abused. Every part inside is original and in excellent condition. Just amazed that I was able to purchase this so reasonably.
I didn't have the camera in the shop, I'll get pics tomorrow...:flag:
