Front Spindle Question

[J Smith]

Is there supposed to be this space (white arrow) between the inner bearing and inside of the spindle? This is as far as the bearing can be pushed on. Or am I missing something from my my assembly? There was nothing there when I took it apart.



I see there is a spacer that is in there in this drawing, but I think that's what the red arrow is pointing to, correct? Or is that a part of the spindle?
Here's the pic of the spacer from Pelican's catalog:




Thanks.

Josh,

No there is not normally a space there.
The bearing isn’t on far enough in your test fit.
Look to see if there is a burr or something preventing it from sliding on.

I like to remove the wheel bearing seal race #42, clean
and inspect the spindle root, replace the O-ring seal
#41 (999.701.084.50, 25.3-2.4 mm).
I grease all the surfaces before reassembly.
The seal race will slip on if heated to 100C or so.

Remember that the outer race of the wheel bearings are
pressed into the hub and are seated against an internal
step in the hub.

The sequence of assembly is to have the inner (larger) #45
bearing all clean and greased and fitted in the hub.
Then install the wheel bearing seal #47 (press fit in the hub
on top of the bearing.)
Put a little lube on the seal lip and the seal race (the part in
red) #42 and slide the hub onto the spindle.
If it was a tight fit with your test fitting, cool the spindle and
heat the bearing slightly.
It doesn’t take much temperature difference.

Once the hub is in place, install the clean and greased
outer (smaller) #46 bearing, the thrust washer #48,
and adjusting nut #49 & #50.
You can use the tightening of the adjusting nut to make
sure the inner bearing is forced all the way on and is
seated against the seal race.
Only do this WHILE TURNING the hub simultaneously and
it doesn’t take much force.

Back off the adjusting nut for proper bearing clearance
and tighten the lock bolt #50.
The wheel bearings should have slight clearance – no pre-load.
It is best to check again after a few days of driving.
Coat all the internal parts and surfaces with grease to prevent corrosion.

Thanks Grady. Very nice directions.

So, is the red highlighted part in my diagram (#42 in your diagram) the same part that the red arrow is pointing to in the picture of my spindle?

I have yet to receive the new parts from Pelican, but I was just trying to figure out how things go back together. It just doesn't seem like that inner bearing will slide onto the spindle anymore. I haven't forced it at all, but there seems to be a mark on the spindle that coincides with how far I can push the bearing on...like that's where it was before.
