Sorry to bump up an old thread, but I would like to confirm if the 1/3" (8.5mm) spring length applies for both axes. In my mount RA came with the factory 8.5mm but DEC is at 6.7 mm and I suspect that this is some of the tweakings made for the vendor to eliminate play in DEC (RA was also "adjusted" but touching only the back-off secondary screw).? The fact is that I have seen recently DEC Heavy Duty Tr messages that I think are caused by overtightening.
Best regards,
Daniel
