I have a Case 580 Super L. The tractor has about 6200 hrs on it. I grease it often but has started showing signs of wear. I need to take up some of the slop in back end on all pins especially ones close to the bucket. Do you just put schimes in it or is there another and better way? Thanks in advance.
If the bushings are not worn out, you can get away with a pin and bush job, if it went too long, its a line bore gig. The way to check is if the new bushings are sloppy in the holes, thats the outside of the bushing and the inside to the bore.
Usually it's the pivots under your feet that wear out, lots more pressure on those compared to the junk out at the bucket. I suggest you have somebody that likes you, run the hoe while you eyeball the pin and bushing interface. You'll probably find it's the pins under your feet are the problem.....
The best way to eliminate the slop in the backhoe is to replace the pins and bushings with new ones. If you are mechanically inclined and have the right tools it is not that hard of a job.
Sometimes those swing towers are cast iron.If the bores are worn they are hard to bring back to standard size. I've often bored them and made oversize bearings for them.
There is a fair assortment of aftermarket repair kits for the swing towers, consisting of new shafts and weld on bushing bosses......not for my old 530CK however with blind bore pivot cylinder pins.
i replaced my swing tower on my 580 sk put all new pins shims and bushings that i bought from case dealer i evan replaced the weld on spacers why do i still have lots of slack everything fit tight i followed all diagrams we evan had to freeze new bushings over night they were so tight
for what its worth i did the same job on my 580sk 1st time with after market pins and bushings a year later my swing tower broke and when i pulled the pins i replaced they wern't as good as the ones that had ben there 23 years there was a lot of slack also so i replaced swing tower pins bushings shims and weld on spacers purchaced at dealer and i still have to much slack maybe i need to add more shims but case wanted 9000 to do the job i did it for around 5500 and i guess im still not done
Can you isolate where the slop is? If your slop is where you installed the shims than I would suggest more shims. Pins and bushings may be tight in the swing tower but you also have to account for the rod eyes (on the swing rams). If you can not locate any slop in the pins and bushings than I would suggest you look at the swing cylinders. First suspect will be the trunion bearings. If the swing tower needed replacement than the trunions probably did too. If you think that the trunions are OK than I would look at swing cylinder internals. If the nut is loose on the piston (holds the piston on the end of the rod inside the swing cylinder) that will allow the boom to swing back and forth. If this is the issue it needs to be addressed immediately as it can get costly if left in that condition.
