It doesn't take much misalignment to focus the stress on the edges of the teeth. They are quite brittle, so I imagine they eventually fatigue. I'm pretty sure that's how I exploded 2nd gear in my...

If not debris, I'm going to guess case flex or some other alignment issue. That sux! Any idea what the diff preload was like the last time you had it out?
Just to make sure my age hasn't caused a brain fart, from the 87 FSM, in the section titled "A-520 Improved Front-Wheel-Drive Manual Transaxle":
"To reduce wear, the manual transaxle now uses SAE...
So when you turned the brass pads around they were pretty clean on the 2nd gear side. Now after two passes they are worn unevenly again? Sounds like a fork issue, though the excessive wear is...
Actually, the '87 FSM and up spec 5W-30. '86 FSM and down spec ATF. So the A520 and A555 both got 5W-30. The word was they used ATF because of winter shifting performance, but I haven't seen any...
If you could actually get *new* parts for these trannies, they might hold up better. Now all you can get is bearings, seals and the odd synchro if you are lucky.
If the slider is pushed unevenly by the fork, the teeth on the stop ring will get past those bumps in the grooves of the slider. The stop ring teeth are supposed to get "stuck" on those bumps from...
If the fork is bent, then flipping the pads over would have made it worse for sure. Uneven pressure on the slider is what makes it grind so much like that.
Prolly. Dang things. My money's on one pad being half gone. Were these still plastic?
Does the whole motion feel stiff/crunchy? If so, that will clear once the loose steel shrapnel is out of the slider. If it keeps grinding, I bet you trashed one pad. Happened to mine and it got...
Hmm...it shouldn't wiggle that much. On the other hand, your case has been "modified" behind the slinger. If the bearing can be taken out without hurting it, it might be worth putting some kind of...
Nope. Mine wiggled a little too on one of them.
It was something Ed Peters said. Then he went off on some tangent about how New Process was storing the castings in the parking lot or something causing them to crack...or something like that. This...
Missed shifts won't do that (no torque). It's when he hits the gear that probably pisses it off. :) The most force on the case will be 1st or 2nd gear (depending if he actually hooks in 1st). ...
Yeah, the crack is a definite sign. Wonder if there is another crack somewhere or maybe it has to do with how your block is supporting the bell?
The only reason I can come up with as to why the race would walk off the shaft is if the shaft was not square with the bearing and the rollers were literally skidding across the surface and working...
Off the shaft? Dremel with a flex wheel. Get as close as you can without hitting the gear or the shaft. Then hit the slot you made with a cold chisel and sledge. I still couldn't get it off and...
The inner race walked off the shaft?!? It was a PITA to get the new one on my A568...that sucker was TIGHT. I had to chill the shaft and heat the race pretty hot just to get it to START to go on...
Check the Al plate for flatness.
It's been eating aluminum. Do you know why your shaft was walking yet? I've never seen one of those ball bearings (at the front of the shaft) fail. Is the clip on the shaft in front of it intact? ...
If i remember correctly, I just use the regular jaws. Now that i think about it, I did have to grind on both my pullers to get the jaws securely behind the rollers. I haven't used the slide hammer...
I've pulled them out with a small puller with the arms reversed. Normally, I'd put a socket over the oil guide thingy to protect it, but you don't have that problem. Now that i have a slide hammer,...
I've seen at least two types (short and long post) and two colors (black and grey). Not sure if one implies the other or why they are different.
I bought all my bearings from drivetrain.com, but that was about 4 or 5 years ago. They were not cheap, but still cheaper than the dealer.
Putting a new gearset into an older case should be trivial. You just need a donor '89 A555 to get the right fork assemblies. I know the 3-4 cluster is the same between the '89 A555 and the A568. ...
