Hi all, I'd like to pose a quick RA tension question for you all:
While looking this morning at a new Q 3.5 owned by Forum member 'Old Don' we both noticed that the tension on his RA drive gear was much more severe than on my 1986 Standard - it is clearly not the 'buttery smooth' movement that I feel on mine, or that one might expect. On closer examination, we noticed that there are three *very* thin plates that fit into a tension gear at the bottom of the RA drive shaft. On my scope, all three plates fit within the grooved indent on the smooth gear, while on Don's scope, two of the plates rest inside the indent, and the other is below, thereby 'splitting' the plates as the RA gear moves.
I believe this might be an easy fix by removing the RA thumb gear at the top of the clock drive and just wiggling the shaft so the three plates all rest within the indent (but then again there may be no 'play' at all in the shaft, requiring more effort). Questar may ask him to return the scope, which would be a hassle (and perhaps should have been caught during their final QA process), but it might be a simple fix.
Do any of you know if this is as easy a fix as one might expect? Do any of you know if this is perhaps covered in one of the Questar repair videos that have been posted, and if so can you point us to it?
