The ZD331 has stops welded onto the frame on both sides - looks like they're meant to keep the axle tube from getting sprung backwards. The left side of the axle on mine starting banging against the stop at 60 hours. The solution was to tighten the bolt on the pivot pin - not sure how it would have loosened with a clip holding it stationary. After the tightening, the left side gap (between the axle tube and the stop) is about 1/8 inch, while the same gap on the right side is about 3/8 inch. Clearly the axle tube is not square with the frame. The service writer and I went into the shop to look at a brand new ZD331 that was just being set up for a customer. The clearances between the stops and the axle were exactly like mine. From this I assume mine is not damaged in any way, but I am wondering if others with ZD331's have a similar disparity between the right/left axle clearances. I am also interested to know if anyone can offer a suggestion on why Kubota would "design" it this way. BTW - if this is the wrong forum to ask this question - please let me know. Thanks.
