Just received my unit back from Sears for a broken Z-truck. Couldn't wind the head up or down and found that our friends, at UPS must have shook it up pretty good. Anyway, I got the head lined up using a 2' level, and now when winding up I have a lot of drag, to the point that I'm afraid I will break the tierod assembly. Cranking it down is relatively easy, however, it clicks about every third revolution of the crank. I cannot get any more than 52lbs of pressure on the scale. I have added and subtracted the washers on the clutch crank handle from none to 4 and I am in the range of 32-52lbs of scale pressure during the adding and subtracting of washers. I should add that I have lubed all posts, leadscrews, and tierod assembly with white lith. When I losened the 4 posts I noticed something perhaps out of place (see Pic1). I believe that the washer that is on the post, and is the exact size as the clutch handle washers, should be eliminated and the flat washer on the bolt should be on the top of the post between it and the lateral stabilizer casting assembly. Pic 2 shows the order in which I removed the bolts from each verticle guide rod.
Pic 3 shows how hard the machine must have been dropped to bend up that section of the plastic.
So before I send this back to Sears any ideas, on the low scale pressure and the order of washers? Perhaps the "All Knowing Al Who" could lend some expertise!
