I have saved several by cutting the bends off at the carb end, then work the wire out of the sheath and soak it in ATF.  Polish the wire, reinstall and rebend the carb end.

I’ve had one soaking in a bucket of diesel fuel for months, with the rubber sheathing cut off.  Last I checked, it’s locked up tight.  Would ATF work better than diesel?

Do a search online. Don't take my word for this. If I remember correctly the best penetrating fluid found by anyone yet is a mix of ATF and (((maybe acetone??)))

 

I have found that the ATF alone works better than diesel or other penetrating fluids.

That LSD ring looks heavier than the one in @stevasaurus’ video.  Is it my imagination or did they make it heavier?

I didn't get time this weekend to get the old one apart. I'll keep you posted.

I haven’t tried it, but believe it.  My auto shop teacher in high school taught us that ATF is the best fuel system cleaner, engine cleaner, pretty much anything.  It is such a heavy detergent that is one reason why transmissions have such a high service interval.  I have used a quart in my engine oil a day before an oil change, in my fuel tank or capful at a time directly into an intake quite regularly.

Do you have a parts list from them Randy?

I don't have a parts list. When I talked to him on the phone I gave him the model number that I had and he knew right away the kit that I needed. My pump and all was a 90 -2046. 

here's a pic of what came in the kit.

@pfrederi

The o-rings you sent me for the motion control. 

Where do those go?

 

[pfrederi 17,741]

#52 and #55. 

 

You drive the roll pin 54 out through the holes in the housing 49.  Pull the arm 53 off.  Remove the 3 12pt head bolts  #50 (you need a 1/4" 12 pt socket) housing will come off.  Big square ring goes in the triangular plate.  Small O ring on the pump shaft and seats in the back of the housing.

@pfrederi

Excellent. Thank you! 

[ebinmaine 67,711]

Finally took a few minutes to work on the differential. 

Disassembled that and looked at the existing LSD spring. Well worn. See the pic. 

Gears all look good very minimal wear. 

 

Next chance I get I'll pop some new axles in there and begin cleanup and reassembly. 

 

 

 

[ebinmaine 67,711]

Got the replacement axles cleaned/wire brushed up. 

 

 

 

 

[pfrederi 17,741]

Snap ring grooves look great.  So many used axles the grooves are wallowed out.

The short side on the one that was in the transmission and also the one I'm putting back in.... I had to wire brush and file that one some. The other side was great.

I probably have 10 or 12 axles that were left over from the auction pile a few years ago. They all need new keyways but the ring grooves look good. 

[ebinmaine 67,711]

Yesterday I had mocked up the differential to make sure everything felt okay. Can't finish assembly until I get Loctite.

 

I spent a few minutes tonight just cleaning up a couple things and removing the old park pawl.

Tried out my new roll pin punch set. Super awesome when a set of tools does exactly what it's supposed to.

@pullstart

I forgot to take an actual measurement of the LSD springs while I had both in my hand but if you look at the above pictures I would have to say that the old one is visibly smaller though not by much.

 

[ebinmaine 67,711]

Neither of the pictures below is my own transmission. Just a couple reference shots for the future.

Thanks to @meadowfield and @Mgryder1 for the pics from their old threads.

Is there a best way to clean the metal transmission screen and remove the shavings from it?

[ebinmaine 67,711]

Differential assembled. 

New nyloc nuts. Blue Loctite.

Lots of brake clean some low pressure air and a soft tooth brush

That's pretty close to what I did. I also used a neodymium or rare Earth magnet to get a lot of the filings out from in and out side of it.

 

[ebinmaine 67,711]

Got the interior transmission parts including the screen all cleaned up and set aside.

 

 

 

 

Scraped all the excess old gasket material off of the two case halves. I shined up the machined surface where the hydro pump bolts on with some sandpaper.

I'm going to let the case halves sit in a soak of incredible pink degreaser for a little while. Maybe overnight. Not going for perfect because we are not painting it at this time but I'd like to have all the fins cleaned out and degreased.

Case halves all cleaned up.

Gearbox is together. 

I used all new nyloc nuts. 

Cleaned up and double checked all the bearings. They were great. 

Just need to pop in the outer wheel seals and add hubs.  

 

Put in a new brake pawl shaft seal but I dented it slightly when installing it. Straightened it out. It'll either leak or not. I didn't have a spare because I forgot to order 2. 

 

Axles I used are a touch longer than stock. You'll see the difference once the hubs are on.

Been there done that....   I always order a couple extras now as teh seals are cheap enough but shippinig to get one or two is ludicrous.

Funny thing is I ALWAYS order a spare or two. I did with the wheel seals. 

Oh well. 

If it seaps a bit I'll pull it back apart. Not a big deal. 

[ebinmaine 67,711]

Here's a shot that shows the hubs as installed.

If this was a regular hydro axle set the hubs would be basically touching the transmission housing.

The way it sets it's just about two inches wider across the back than a comparable 8-speed.

 

One of the hubs had two good set screws so I put two new set screws on the two axle keys and the two decent used set screws on the axles. Added my lug bolts and tightened everything up.
