Hello Arukle,
Thanks for the information.?
I am not sure this will improve Any tracking issues. What it will do is engage more of the gearing surfaces.
This distributes the contact load and may thus smooth? out the smaller 'second to second'
tracking? imperfections.
I used the shim set as 'feeler gauges'? I stepped up in 0.001" increments .. I found one spacing where I could not,
or barely lift the ring-spur gear, and going 0.001" beyond that caused lockup when I pushed the ring down on the
thrust bearing group. That was my indicator of correct spacing : If I could press down hard on the ring upon the
thrust bearing and maintain smoothness in the feeling via the added? manually turned worm-shaft knob,
I knew I? had hit the best spacing.
When adjusting the worm-block set, it is imperative as others have stated, to keep firm pressure on the
right block to press it against the 'fixed' left block to eliminate worm shaft play. I used the cover plate
to align the blocks square to each other, but there is a few degrees of rotation alignment freedom in the
bearings, so you can lock the left and make small adjustments to the right block without issue.
