Loader pivit pin replacement

[Usta]

I noticed my loader bucket has some slop in the pivit points. No big deal but was wondering what typically is needed to tighten it back up. I realize no true answer can be given without knowing the true extent of the damage but is it usually just pin replacement? Is it usually a drill out with new oversized pins?

NOPE!

Both the pins and the bolts retaining the pins have

to be replaced.

You need to take all the pressure off the boom arms

to remove the pins to avoid binding to remove the old

ones and install the new ones.


AND youy can only change one pin at a time.


Better to do it now and avoid breaking the

pin retainer weldments in the near term as you will

be in a world of hurt.

I bought a well used Westendorf loader for my big tractor and it had pretty well worn out pivots. I used 4-flute drill bits to oversize the bores and used over size pins. I'm a machinist with access to a large boring mill which is where I did this. Not sure how an average Joe could do this in his garage. Changing pins may be all you need though. You won't know until you pull one out. Maybe there will be replaceable bushings.

Thanks
Like I said it is minor slop. I have pulled all of the pins and by eye or feel I can not tell of any significant wear. I did not bother to mic them. My main question is on Kubota quality and if their bores are of harder material than the pins. I have seen low quality equipment where they are of similar material and re boring is standard procedure.

Most of the time,you will run a loader until there is a SIGNIFICANT amount of slop and then replace the pins and bushings. But, if the pin was allowed to rock because the bolt was loose,then the DOM tube may need to be ground off and new welded in place. That's a PITA job. Do it once and you will be VERY motivated to grease it up every 8 hours!

Are you talking about the 2008 Kub in your signature? Hard to believe any significant wear in what, a couple hundred hours? Possible it was built with the wrong size pins but I'd just keep it lubed and forget about it for a dozen years or so.

Mine has some slop with the bucket curled all the way back. But, it's not in the pins, it is because of the geometry of the curl cylinders. With it all the way back, it can rock when the cylinders pivot. If I curl it forward just a touch to change the geometry, all the slop goes away.

But, good reminder for me go get the grease gun out.

Operation in sandy or dusty conditions with no lube will wear pins and bushings extremely quickly. Worn out in 200 hours is easy to do in those conditions.

Are the pins softer and designed to "take the wear"? I do see the pins are retained so they can not spin. Is it possible to turn them 180* and get some more life out of them? I am not having problems, this just got me thinking....

Turning them will not help. If they wear to far they can break under a heavy load. If you can't make new ones yourself, then take one to a machine shop and they can make new ones. Pins are pretty cheap to make. It's better to have the pin wear than the bushing. Bushings are a bit more work to replace.
