Yes, we're still at it!
 
Here is a update with the transmission for my 72 that I'm working on. Here, I'm ready to make a new axel housing gasket from the new gasket material bought from TSC.

Next, the gasket is finally sketched out and punched. Case and the axel housing are cleaned up and ready, as shown here in these two pictures.

A thin coat of a gasket sealant is now applied to the case, and the new gasket stuck on.

Axel housing now joined to the case, and tightened down. Notice not a lot of clean up required between the two mating surfaces.

This picture will be used to think about what all is ahead to prepare the transmission for a sealer touch up, and finally a primer.

When I installed the two new wheel seals, the seals seemed to have become concave, meaning pushed into the axel housing in such a way that the geometry of the rubber seal is no longer perfect circle. I'm afraid I will have to replace them both. You can sort of make out the seal problem I'm facing in picture # 1.

Also, I need to replace the rubber o-ring of the brake retainer. Once that is done, I can make another gasket for the reduction housing cover. Have had a few mistakes along the way with this topic of the paint prep. But at least I'm sticking to what I enjoy doing. Hope to have the transmission in primer in two weeks.

Thanks!

Did you use a seal driver putting the seals in?

Sam, I never replaced wheel seals on these tractors before. I don't have a seal driver. I do have access to all different diameters of cylindrical aluminum stock from work which I was thinking of using for a seal driver.

Sam, what is a seal driver, and can I in fact fashion one from the stock I mention? I don't know what to do here, but order new wheel seals. Seems like its just been a row to hoe with this transmission.

Thanks for any help you might offer!

I have a Mac Tools seal and bearing driver set looks a lot like this.

You need to drive the seals in straight with something flat or they get bent.

Keep up the good work, John!

before i bought a seal installer tool i used to use large sockets or bearing races or a block of wood

That seal may or may not leak but to test it you could stand an axle on end, slide the tube over it and fill the tube with some diesel fuel and see if it leaks, before putting all together. just a thought.

The link on the seal driver from Northern Tool is helpful, Thanks! Here are 3 pictures this morning. I went out and with a black marker, scribed on the seal where the concave begins and ends. On the left side, the black mark goes across the U.S.A letter stamp. On the right side, the black mark appears to the left of the seal looking at it. The remainder of the seal is flat, and looks correct.
You might be correct on thinking the seals may or may not leak. {I'm scratching my head at the moment} Since I already have sealed and installed the left side axel carrier, I'm afraid I don't want to remove it again. Your idea about the test is a good one, or at least seems logical to me as well. I will remember that!:biggrin2: The wheel seals cost about 6- $7.00 each from my local Cub Cadet dealership, so not a huge expense here.

Here is the left side.

The right side. As a side note: This axel carrier don't appear to be leaking, I don't believe I will separate from the case to replace the carrier gasket.

Here was the test. I understand I cant see for sure how the rubber seals the axel, but the fit seems good. That's about all I know.

Regardless of all these uncertainties, I'm headed back out to take advantage of a nice, warm sunny morning tinkering with the 72 project!

Sam, My ears are on! We're heading up with this experiment, it is in the works now. I hope 4-6 ounces of engine oil could be substituted in place of the diesel fuel. However, I don't recommend removal of the left carrier, ie: the carrier I just installed.

Allen, Thanks man! I'm looking forward to seeing what all turns out today, and where we will be by the end of the day. See, this part is the last big ordeal, and the rest of the project is nothing but what I'm better at: PAINTING! :Woo:
