Excellent.... you're the man.? I tried unscrewing it, and it is indeed frozen.??
But wait.... I kept scratching my head.... I knew I had an adjustable pin spanning tool somewhere.... but couldn't remember.? All of a sudden it dawned on me.... for changing wheels on a hand grinder.
Attached is the perfect tool.? I checked the torque on both plugs.... RA and DEC.? I would say it could have been construed as loose..... no torque on it.? I loosened both plugs, and torqued them.... did not put all my weight into it, but much more torque than I had.
I slewed all around with no stalls and no strange sounds with either axis.
I will try this out tonight.? Thanks!!!
