T/C bearing preload shims

The end play was right at .005. After taking the cap off on a few times and changing a shim the final setting is .007.

I put the cover on and filled it with oil. Let it run about 10 miles on the odomenter with the drive shafts removed and it started leaking oil again.

Woe is me!

Update on my oil leak.

On closer inspection of the companion flange I can feel a slight wear in the seal surface. Since a new seal didn't stop the leak I ordered a new flange and seal. The one that is suppose to have a double lip, and for the life of me I don't see two lips.

Anyway, I'm at the point of installing the companion flange, but I have a descrepancy in the new one versus the old one. The new replacement flange is about 1/8" shorter than the old one.

Now here is where I am not sure about what the heck I'm doing. Because the TM doesn't give much instruction on installing this part.

Yet Willys Tech instructions says to install the flange the washer, and torq the castilated nut to 100-120 ftlbs and install cotter pin.

Now with the new flange on there is no way the washer comes in contact with the flange to tighten it up because it slides on the splines past the ends of the splines.

So let me ask this question. Is the companion flange suppose to float on the splines of the output shaft. Or is it tight against the speedometer gear and then the bearing?

I guess I wouldn't be having this task if the flanges hadn't thrown me for a loop being different shaft lengths.

Ok, yesterday I was talking to the man whom sent me the short companion flange who hasn't worked on a transfer case in years was his story. And was telling me contrary what I was thinking about the flange having to be torqed in or at least tight. His views were opposite of mine. So did that confuse me? yes it did. And is the reason I made the previous post.

So later he gets back with me after confirming with co-workers who work on transfercases that yes I was right and he found a companion flange that matched the spline length of the one I was replacing.

I'm waiting on it now. Boy!!

I started on this job 20 days ago.

So now what's the deal with different flanges?
