Thoughts ?

Question? On my rear tire I am getting what seems to be 90w oil from the pumpkin dripping from inside the hub. The hub seems pretty hot and I am wondering if something is heating up the hub causing the oil to expand and rise up to the vent holes and then drip out. Or is there some kind of seal that may have let go letting the oil leak out.
One more clue when I replaced the tire i noticed if I tighten the axle bolt to much the tire would not spin. My impression is the tire rides on 2
bearings so if I put the tire back on with all the correct spacers why would it not spin after I tighten the Axel nut ?
So could the bearings be seized which in turn stop the wheel from spinning and over heating the hub causing the oil to expand and then leak from the breather holes ?
How would the collective minds out there proceed ? Thanks for any help.

First, you need to sort out exactly which spacers are missing or incorrectly installed on or in the rear wheel, correct that, then install new wheel bearings and see where you are.

The leak could be related -- if I'm picturing this correctly, you might be missing the final drive spacer which would allow the spline to chew into the seal. There's a spacer in the final drive that can fall out when you remove the rear wheel, then a spacer on either side of the rear brake mount. Over on the brake side, the "hat" shaped spacer goes on the inside, and the tapered spacer goes on the outside.

The spacer between the rear wheel bearings is #5 on the diagram, and the spacer inside the final drive is #7:

Tightening the axle should not make it hard to spin the rear wheel. Granted, shafties always have a bit of resistance -- you can't get the wheel to spin freely just by pushing and letting go -- but you should be able to move the rear wheel easily by hand.
