I'm actually guiding now without the thrust bearing on my RA. ?I put in a temporary shim for now. ?Just waiting for the actual ones to arrive from Mcmaster. ?
What the shims do is support the inner race of the existing large ball bearing so that the worm gear rides where it's supposed to go. ?In my G11G that is .018 shims to get it there. ?So the shims don't drag, they just lift the ring gear up to where it would be if the thrust bearing was still in there. ?Hope that makes sense.
The large ball bearing really doesn't do anything other than center the ring gear in the G11G in its stock configuration. ?What I've done is put that large ball bearing into service as a thrust bearing in addition to its centering job.?
I probably didn't explain myself very well in the original post.
