Trying to find the bearings to overhaul my 54 rearend
The only bearing I can't seem to find is a roller bearing.

The original numbers on the bearing are:

Hyatt O.R. 1506

I've tryed a few bearing suppliers and they say it's been discontinued.

The approxamate dimentions are:
Id 1.8287 (55/64th)
Od 3.125 (1/8th)
Width: 0.784
Roller bearing has no inner race.It rides on the pinion shaft.

any info on this would be greatly appreciated.
Thanks....BEAR :rolleyes:
