case 580k backhoe kingpin 4 wheel drive

[Lou Peterson]

how much work is involved in repairing kingpins for a 580K 4 wheel drive

Welcome to HEF, Lou !
Quite a bit. Do you have a service manual ?
If not I recommend that you get one because you will be needing it many times.
I can copy and email you the pages showing the procedure if need them immediately.

I also have a question if the kingpin you are referring to is the pivot shaft for the front axle.

How do you check for worn bushings & pin on the front axle?

580M

Thank you

Lou has a 4 wheel drive. #12 and #16 are what his kingpins look like.
Put a jack under the counterweight and slightly raise the front of the tractor. Any looseness can easily be seen in the axle center pin not the king pins.

My 1956 Powerwagon has a similar set up. The manual calls them trunion bearings. I'd say it isn't a big deal to replace, or reshim them. Mine needed seals, and if I recall we replaced wheel bearings at the time, the planetary was leaking.

If I recall correctly, they are tapered, and minor wear can be corrected by removing three bolts top & bottom, and removing shims. It IS something you'll want a manual for.
