How To: C15a Wire-3 restoration

Jordan,
Regarding your question about the bearing fit on the splined shaft. The bearing should be a press fit on the shaft. Same as the corresponding cup should fit tight in the bore. You want the rolling elements of the bearing to do all the work, not the inner or outer race spinning on the rotating parts.

Thanks Tony for doing the drawing.

Perry that was my thoughts too. But now I’m confused.

The following refers to those parts circled in the red on the exploded parts drawing. The parts lists referees to the bearing cone as Timken #462. This is what I removed from the knuckle when I first pulled it apart and have since ordered. The new and old bearing match up.

Here is the axle shaft in question. Both sides are the same. This goes from the CV joint to the hub.

This is the grease slinger. My understanding is that it fits on so it sits flush against the shaft. The lip would point towards the splines.

Here is the original Timken #462 bearing cone. This was my concern as it has quite a loose fit. However the wear marks on the grease slinger match up to bearing surfaces.

Jordan,
Is there something on the hub that fits into the cone when assembled? Surely that splined shaft can't be left flopping around inside the cone.

[Jordan Baker]

I just had a eureka moment with your comment about the hub. Yes there is shaft on the hub that fits into the gap between the splined shaft and the bearing.

Bingo!!
You have just won a Kewpie doll!

It is that piece, (6.3075 in the parts photo) along with an appropriate amount of shims, (6.3076 in the photo) that sets the front wheel bearing preload.
