Finally got the input shaft nut off with 2 home made tools: 1) cluth plate screwed into the wall to hold the shaft in place, and 2) a welded up 42mm socket to turn the nut. It still takes a long breaker bar and 2 foot cheater bar.

It is too clean to be on the way out. It must be a picture of it on the way back in with a Wevo plate ... |
The case came back from the machinist, ... with a new CV flange bearing / race. In removing the old bearing from the differential, I notice there is a shim under the bearing. $1000 question ... does that mean I now have to check the differential and adjust the way it fits in the housing with respect to the side load shims? how?

To answer a question from a few pages back, yes, we do plate the races to oversize them. However it's not chrome. We use a far more malleable metal that's more workable and not going to cause distortion to the race when it's reinstalled in the case.

Hi Matt
Good to know... allbeit a little late for me :) |
I got the input shaft and gears back together, tightened the big nut to 165lbs, and found that the gears 3 and 4 move back and forth a bit, about 0.2mm. pictures show the feeler guage where the gap is. My guess is it is normal because these gears have to free-wheel on the input shaft. If there is no gap, they don't spin. Is that right?

I like to clean up the input shaft threads a bit. Does anybody know what size tap and die that is? Not the 42mm (clutch side), but the smaller side where the 1st gear is.

Cleaning threads. I've always used a nifty tool called a thread file/restorer that I've had in my toolbox for about 30 years. It has a length of "file" for each thread pitch, takes a little time to use, but does a fantastic job. |
So, the 2 shafts were assembled dry. I used a heat gun on the pieces to go on the output shaft and they all slid home without any problem without a press. I installed the gear stacks in the case at this point. I am at the point of mounting the intermediate housing. Is it acceptable to pour some oil on the gear stacks just so they don't start out spinning dry on start up?

I replaced both of the differential carrier bearings (SKF). lacking any instruction on how to adjust the preload, I installed the diff, marked each of the outter race with 4 lines of markers, put the cover on, torqued to 25Nm to close it up, and turned the output shaft with a drill, and removed the cover and the diff, looked at the marking left over and this is what I found.
speedo plate side of the diff, marked with red pen, the marking is all gone http://forums.pelicanparts.com/uploa...1244397105.jpg Cover plate side of the diff, the marking is in black pen. The marking is almost all gone. http://forums.pelicanparts.com/uploa...1244397174.jpg That is telling me, the preload is too much. Please help out and comment. |
I am finished. It is in the car, running, and not making any more funny noises. A great big thanks to all the advisors on the board.http://forums.pelicanparts.com/uploa...1244778633.jpg
