I opened up my mounts' side lid and inspected those green and red bolts you mentioned, but they are all tight.
I would expect them to be tight.
Basically, to adjust the clearance between the gears themselves, you would ease off the relevant bolts
and then move the assy as required to tighten the meshing.
You said "joints maybe sloppy", do you mean the distance between RA transfer gear and RA idler maybe too far to cause some backlash?
Yep, either side of the idler might be a loose fit and hence give the result you saw.
That said, it may just be my eyesight or the lighting, but the teeth on the RA idler do not look like
a normal involute tooth form,ie they may be worn??? Dont know there.
Can you clean the grease of the edges and then get a very good face on close up of the RA idler
so we can see the tooth shape??
I tried to turn the transfer gear by hand and there are some backlash I think. Do you know how to test them so that I can know how well they are meshed against each other?
The normal test is turn the 47 toother on the worm back and forth and see how much slop there is
before the idler gear reverses and takes up the load on the motor gear..
