D35 TTB Axle Support Bearing Depth...

[HsOffRoad]

Does anyone know if there is a specific "depth measurement" for how far the roller bearing that supports the inner section of the long side axle shaft on the D35 TTB is supposed to get pressed into the diff housing? There is a ridge machined into the center of the housing, but if I press the bearing in that far, the outer race will be covering most (if not all) of the breather hole, and the bearing probably won't be riding properly on the smooth portion of the axleshaft.

Obviously, the bearing needs to be pressed in far enough to allow room for the oil seal to be installed properly, and the bearing has to ride on the smooth portion of the axleshaft. I find it hard to believe that Dana wouldn't machine a stop for the bearing into the housing... but having the bearing covering the majority of the breather hole and not properly supporting the axleshaft doesn't make sense either.

The bearing that came out of there was not factory, and whoever installed it had it "just kind of centered" in the bore.

As usual, I figure if anyone knows this, it will be you guys.

Thanks,

I would press it in just far enough that the seal can be installed.

I just replaced the seal, i will agree, mine is only pressed in as deep as the seal goes, give or take a mm for clearance.

Thanks for the responses guys.

That was my initial plan - mechanically it makes the most sense because it maximizes the distance between the two support points, minimizing leverage on the shaft.

Funny that they wouldn't machine a stop in there for the bearing, but as long as it provides enough of a press fit to keep the bearing from spinning (I don't think the hole in the housing is tapered, so it should be the same regardles of mounting depth), that's what I'm going to do- just press it in enough to clear the seal with a tiny bit of wiggle room.
