One of the bolts that hold the square drive shaft on to the rear slide gear shaft is not tigntened all the way. (See photo on left). The one on the front slide gear apears ok. (See phot on right.)
My instincts tell me to tighten the screw, but then I checked the other side on our unit and found the exacts same situation...Rear not tightened , but front is...so now I'm not so sure.
Any comments would be apprciated.
