B31 front hub rebuild
« on: 22 December, 2017, 17:43:39 »
Hi Guys

I'm rebuilding the front hub on my 1955 B31 plunger after having the wheel rebuilt and after putting it together as per the service sheet it just doent "feel right"
I would have thought that the outer shell of near-side bearing should be flush with the lip inside the hub and therefore recessed into the hub by about 1/4"; but when put together the edge of the bearing is just about flush with the edge of the hub- see pic. The bearing is correctly positioned on the spindle- ie flush with the retaining lip and the bearing on the other side appears to be in the correct place.  Its so long ago that I stripped it down I cant remember what the original looked like;
There are 2 washers- a thick one with a cut-out (why I dont know) and a shim- I'm assuming the thick one goes on the inside of the off-side bearing and the shim on the ouside of the near-side bearing- the diagram on the service sheet isnt very clear, but in any case the dust cover wont fit

Anybody throw any light on this ?
