Finally a start on fitting the repaired worm wheel. First pic is from the rear or feed side. This shows one of the magic bearing spacers. A long look at the owners manual has this spacer on different sides of the thrust bearing in ea of 2 pics. The spacer under the bearing nut is missed completely. Second pic and you can just see the cover tube for the tower shaft and worm pinion. There is no oil seal there or on the main/counter shafts. The oil is allowed to run past the bearing and collects behind the cover where it drains back down to the box. Third pic is the 2 shafts with gears and bearings. It's a 3 hour job that will take 3 days at least. A lot of cleaning is needed as the bronze chips have filled many oil galleries and jammed up the works. Worse luck the only way to see if assy is right is to put it together and check mesh. The bearing nuts and gears are locked by grub screws and taper pins.
I'll try to take more pics as I go.
Regards
BC
