[Healeys] rear hub

[BJ8Healeys]

When I installed my rear bearings, I achieved the required 0.001 to 0.004
dimension by placing three or four 0.003 wheel bearing shims equally spaced
around the perimeter of the bearing hole in the hub with the new gasket
installed, then placed the spacer on top of the bearing and tapped the
spacer/bearing to seat it using a bar across the spacer.  The bar was
positioned to be stopped by the wheel bearing spacers, at which point the
bearing spacer was installed to the required height above the gasket.

All,

I am replacing the oil seal in one of the rear axle hubs in our '62
tri-carb.  The workshop manual states that the bearing spacer (ATC7569)
should sit proud of the hub and hub gasket 1 to 4 thousandths of an inch.
After installing a new seal and re-installing the R&M bearing, the spacer is
flush with the hub.  The old gasket is 9 thousandths thick; the new one is
12 thou.  So, it looks like I need to make a thicker spacer.  Was a bit
surprised to see that spacers with different thicknesses weren't listed in
the parts list.  Am I missing something?

The O-ring I got from Moss has to be stretched to fit in the slot. 
Unless stretching the O-ring gives a necessary reduction in the thickness,
I'm going to fit a larger O-ring. A 91 mm ID with 4 mm thickness fits well.

Cheers,
