Viscount bottom bracket overhaul (2004)
See this Viscount in 2002 here.
See the 2004 update here.

Charles loves his "Trusty" Viscount.
But one day the crank axle broke in two.
The original bottom bracket had press-fit cartridge bearings
and a square-taper spindle with grooves for c-clip fittings.





A well-worn spindle and bearings were extracted from BB shell.
The original spindle measures 123mm long.
The square-tapered ends, measure 12.7mm wide at tip,
13.6mm wide at shoulder, and 15.5mm long from tip to shoulder.
The bearings are 6003, measuring 35mm OD x 17mm ID x 10mm Thick.



The c-clip grooves may have contributed to spindle failure.



We missed this NOS Viscount-Lambert BB set,
with tapered-end stainless steel spindle, from Hilary Stone.



Perhaps it is better to replace it with Phil Wood.
6003 sealed cartridge bearings and 123mm stainless steel axle.



The shimano-type taper appears to works fine.
