Has anyone ever had any trouble with the blade height adjustment on their Powermatic 66? My once-effortless spin of the wheel now takes a bit of effort. I spray the worm gear and gear segment with brake cleaner and brush any crud off with a brass brush and let dry. I have tried spray lithium grease, spray teflon, and any number of lubricants….they all seem to free up the mechanism, but the sticking soon returns.
I talked with the repair guy where I bought the saw, and he thought it was the worm gear, but, no, it looks like new. (I asked him what to use for lubrication, and he told me to use automotive chassis and bearing grease!!)
Anyway, as a last resort, I consulted the owner’s manual (I apologize for this unmanly behavior). It says, if after cleaning and greasing, the mechanism still binds, to check the alignment of the worm gear and worm gear segment…if they are not centered, binding will occur.
To do this, you loosen the saw raising arm setscrews, move the arm as required and relock. My question is:
I’m no engineer by any stretch, the schematic diagram is (or I am) a little unclear, and the parts list describes bolts by size, not function.
I’d appreciate any help…I don’t want to suffer the ultimate humiliation of having to call Powermatic customer service!
