Harmonyards,
Mechanically I’ve just repositioned the ball bearings inside the bearing blocks at the end of the horizontal worm shaft. They are a friction fit inside the blocks. I was able to tweak the position of the ball bearings so the spur gears would fully engage. Once I achieved the correct end to end position I locked the bearings in place from the rear so they couldn’t get pushed deeper back into the bearing blocks. A pic really wouldn’t show anything as the ‘fix’ is hidden. Before this tweak the spur gears would only mesh on half their surfaces due to excessive end play.
Just as an aside, my two ‘46 Turbines have very little endplay on the horizontal worm shaft and their spur gears align correctly.
