Jon,
I never meant to suggest that your price was out of line. No offense, I hope. C

Question, for everyone in here. I need an exploded view of original wheel bearing parts arrangement, for my 57 panel.
I have something odd, that was on the bus when i got it, and for the life of me, cant remember any of my other busses ever having these.
At the base of the spindle, there is a spacer ring (for grease seal to ride on) then, just after that, is a bellville washer on each spindle. Why in THE hell would those be there?
They would always throw off your wheel bearing adjustment dependant on load?
They were there when i pulled it apart, both sides. i thought nothing of it. but ive been having wheel bearing adj issues, and ive NEVER had this problem before. SO im blaming it on them, because a spacer i could see, but a spring washer? odd.
ANY input would be good from you guys. an exploded view would rock, next step, im taking them out and see how it does.
Thanks again guys. dave

A bellville washer is a spring or wave washer?
I have rebuilt a lot of 1957 to 1967 bus front brake systems, and there never was an extra washer thrown in between the inner wheel bearing and the thick spacer on the spindle. The person who added a spring washer to each spindle was either spaced out or trying to move each drum out, further, for some reason (thick spacers not thick enough or brake plate bent out and hitting drum?). Whatever, the use of a spring washer will allow some side movement of the bearings on the spindle when under stress, i.e., turning of wheels, because the adjustment of the wheel bearing play using the inner nut wouldn't cause the spring washer to flatten out. Also, if the drum is further out on the spindle, the inner edge of each brake shoe would be at the edge of the drum and the inner bearing may not be completely on the thicker part of the spindle, depending on how thick the added washer is.

Hazetguy's idea of grinding down 27mm wrenches works great. I had to track down a metric supplier and got a pair, ground them down and presto! They work great.

SO, after needing a nudge of confirmation, i decided to take those damn spring washers out from behind my bearings, why i ever left them in there.... no idea.
Im lame at times. Embarassed

Image may have been reduced in size. Click image to view fullscreen.

SO the washer is NOT supposed to be there. If any of you ever have a PO/50's shop hack washer behind your inner wheel bearing. Shocked

My bus is like a new bus now. big difference.
Before, i would adjust the wheel bearings perf, then id get out on the road, and at certain speeds, id have the purring resonance of loose bearing adjustment. Id get piiissssed, and go home, double check, perfect. The spring washer was allowing the bearing to move inward, giving extra play, and making the adjustment out of whack.
Bus was a tad wandery, and yet all my suspsension is perfectly solid.
Now...h man. solid as a rock. steering is even tighter than before.
YAY!
Thanks campy for the nudge,lol. Cool

You are welcome, mighty, but we all want to know why some dude installed the spring washers, in the first place. I would guess that he was rolling his own. Laughing

I build bicycles, part-time, and to hold that skinny inner nut I use an old Campy bike wrench. You can get a cheap non-Campy version at a bicycle store for little cost.

Weird that that washer was in there. That would seriously mess with the free play setting.

I had a somewhat similar problem where some "mechanic" used the wrong size wheel bearing. Ran fine as long as you drove in a straight line. When you turn the wheel, the wheel tilted and locked up.

snap on carries some very nice slim line wrenches in 27mm that work great for spindle nuts
