This is the snap ring in the case for the f4a42-1 transmission. For some reason, it actually prevented me from removing the outer race for the bearing that goes under the round plastic cover on the outside of the transmission. Now that I have the new bearings ready, I cannot get this snap ring back into place. Nothing I have tried has worked. Please, and help will be appreciated! I need this transmission to be together before the end of the week, and at this rate, it might take just that long.

 

how did you get it out?

 

If you can see it, there is a notch in the case. A flat screwdriver fit into the groove and another screwdriver was able to walk around it, but when it got about halfway out, it shot across the room and bounced off of the wall. It's so tight that I can't compress it with a pair of pliers, either.

 

why did you need to remove it? How does it engage the bearing, it is the same as the manual?

It looks like a wheel bearing snap ring, the bearing retainer in the manual transmission is pretty soft.

Have you tried sticking it in sideways and just working it in with brass punches?

 

I did not have enough material on the bearing race to strike it with the snap ring in place. That's the "why" for how I removed it.

it came from the small side of the input shaft. In my manual, it is referred to as the transfer shaft.

It is, by far, the tightest snap ring that I have ever seen, even after working with ones that were 10mm thick on paper processing machines. I can hardly compress the thing by hand, and I have tried several different methods of feeding it into groove and working it in with a piece of brass. In the picture, you can see that I slightly notched the case by trying to do this. The groove is between 2 and 3 millimeters deep into the case, and just over 2mm wide. The ring is close to 4.5mm thick all the way around, which is also strange. Most of them are slightly thinner near the ends to allow for a little flexing, and therefore easier installation and removal. This one is just a pita.

 

I am a firm believer in God, and I really think that this thing was just here to try my patience. I guess it got a little softer from being at room temperature instead of outside at 40*F out here near FayetteNam, and it just slid right on in. It's too weird for me to explain, because the thing is still wicked tight. Not complaining, because it's in and I am done! Praise God! I am NEVER pulling another one of those again.
