Axle Pivot Stud
Posted August 29, 2012 - 01:21 PM
I figure there are two repair choices, 1) re-weld the original stud to the frame, or 2) purchase a new stud and mount with both slotted nuts. Either choice will be difficult unless the engine is removed. I think the better choice is to replace the stud.
Was the slotted nut on the frame side welded to the frame? The diagrams do not state.
If so, why? I think welding the stud or nut to the frame only invites failure. Everything on this tractor flexes, so if the stud needs to flex, either the weld or the frame will eventually fail. One the other hand, maybe the weld is there to keep the stud from wallowing out the frame.
Any thoughts. What am I missing?

My 1973 1614 has castle nuts on both ends of the stud. The nut on the frame side was/is factory welded to the frame. My 1980 2418 has the stud welded to the frame with no nut on the frame side. I don't see why there would be enough stress on the stud to break it lose. The axle is supposed to lay right up against the frame - that alone would keep a good chunk of the stress off the pivot stud. I wonder if your tractor had a loader on it at some time? If there has been no loader it must have caught one front wheel on something at full speed or jumped a ditch at some point. It could just be the victom of fatigue from years of use.
If you can clean off the old weld and get the stud to set straight in the hole, I would just reweld it to the frame. To pull the engine on one of those PK's is very simple and doesn't take half an hour. Worse part is those cast iron Kohler blocks are heavy. Good luck! and keep us posted.
Ryan, 1978 PK's are not fiberglass tractors.

I knew that! I must have read it wrong, I thought it was from 1987.
Like Kris said, just clean it and try to reweld it if you can get it aligned correctly.
