Box case also cleaned thoroughly and primed. Thats as far as I can go with it until I locate a new seal for sector shaft. Betwen the two boxes I have now disassembled, there are two very good bearings that I can use (both the worm gear shaft bearings are identical).

Hi Tony, I guess you have noticed that the bottom cup is a lot heavier than the top one. My bearing supplier sourced some new ones from Melbourne. Also have a good feel of the rotation of the sector shaft roller. The needle bearings inside have a habit of collapsing. Good luck. Your thread is really interesting.
Regards Terry.
