Cant remove torque tube from diff housing

[Bob Culver]

The pre Ruby diff has a ball pinion race (fittable to all) whcih may be a neat fit (or Loctited) in the housing, so requires moderate persuasion. (from distant memory the roller bearings had some setscrew arrangemnt to retain the outer ring. I dunno if this can be fitted with a ball race but if so would prevent withdrawal.)
(Just noticed 1938 so unlikely, unless a non standard roller with stepped outer fitted)
