Well... so I was lazy most of the day Saturday, and Sunday I spent most of the day fighting with sewer line issues. Yuck.
But today I was determined to see what's going on in this old transaxle...
I'm usually pretty verbose, a lot of people tl;dr my longer posts I'm sure... and they say a picture is worth 1000 words, so here's a few thousand words in easy to digest pics.
First off, it's a 633A81 for those who want to know those things.
This is the gritty, rusty gunk that was coating nearly everything, but this is a close up of the top differential plate...
Just a lil WD40 and wiping down with a clean rag... same spot...
Almost all of the sliding gear edges are in decent condition, some show signs of a little grinding though...
The rust on the 2nd tier of the layer cake on the far left here is the worst of the rust. Now, mind you, this is the bottom side of the trans. It must have been pretty wet in there at some point.
Gotta check all the bearings, so lets pull it all apart.
Little more out.
Deboned and ready to fry!
Tried to get a close up of the gritty gunk clinging to the bottom of the case.
Here's a bit of the grit-sludge that I pulled up that was clinging to one of the ribs of the case.
Close-up of the rust on the layer cake... Gonna try and knock it off the faces with a wire brush and see.
Another pic of the jigsaw puzzle... I'm sure many of you are thinking "will he ever get that back together right?"
So far I only have the seals for the axles, and I know the input seal is shot also. The brake shaft seal seems good, but seems stupid not to replace it while I'm doing the others.
But here's the serious kicker... all of the bearings are still in a condition I'd consider serviceable. WIN!
The only gear that really has seen better days is the reverse idler. It's been ground almost flat on the mating edge. Sears part 1153R, which of course they don't stock anymore. If I can't find one, I'm debating filing the burrs off of it, or just leaving it as is. Unfortunately, I didn't get a close-up of it... had to come in and feed the dogs.
