Well Garrett and I modified his KA tranny earlier today. I had no idea what I was getting into, I wish I had read this thread earlier . Garrett will most likely chime in later to add to this. Well, here are some pictures...
Above, #1 was drilled out to 5/8". #2 shows the Z countershaft bearing in place of the KA bearing. (Yes, pain in the butt to remove the KA bearing! Had to modify a bearing puller)
Above, the area inside the red circle had to be milled out. I believe at least 3/32" was removed.
The picture above points to where a C clip should be holding in the bearing, but the bearing just would not come out any further. So, we elected to leave it off. Experts, PLEASE let us no what may happen if this clip is left off. The bearing is a tight fit inside the bellhousing. It can't go back into the tranny, and it can't come out, because of the cover. I guess, if need be, the bearing can be pulled off the shaft slightly to allow the clip to be put in place.
Well, this was very interesting to say the least. Learned a lot about these tranny's and this whole 'modification'. I was just helping Garrett out, I had no idea what I was getting myself into .
!M!
