Part Numbers:
D90722 - (2)Upper and lower swing bushings
D90727 - (1)Upper swing tower pin
D123653 - (1)Lower swing tower pin
D74249 - (1)Upper thrust bearing/plate/washer shim, 5/65'' (2mm) thick
D73848 - (1)Lower weld on thrust bearing/plate/washer (Frame side)
D89338 - (1)Lower thrust bearing/plate/washer (Swing tower side)
Good to see a young guy working on machines.
I need to do this on my Cat 420. Great video, Wayne. Thank you for taking the time to make and share.
I made bushings and pins on my lathe for a old 1969 Massey Ferguson model 54 backhoe a month ago. It had spherical bushings that are essentially a big ball within a race (think similar to a heim joint without the threads) and they were totally obsolete, not even able to match em up to something close, so bushings and new pins it was and it works great. I had to weld the lower bushing in because the hole was fucked. I drilled and step cut a groove inside the bushings, for complete grease around the entire diameter of the pin. Like I said, it works great and considering the oe parts are obsolete, it is a proper permanent fix and should last what ever life is left on the machine, probably another 2-3 thousand hours. If there is a will, there is a proper way in the equipment world
Just rebuilt the kingpins on ours. Then the boys and I replaced the swing cylinder ear pins and bushings. Liquid nitrogen is cheap and shrinks the bushings perfectly.
take a saw saw and split the old bushing before pressing it out. Just one side does a lot ...2 sides even better
Great video with a lot of good info. Thanks
EXCELLENT! thanks for the work! PS. watch the backhoe frame's attach pins.... I would suspect that the tension rods are not torqued properly.
Good I saw the video before I do mine it took a lot of guess work out of it for me. Thanks!
Once those pins are greased that wobble will go away. 👍
Protect your cylinder rods when beating the hell out of stuff near them, or welding.
I worked on equipment for years and you cut a groove into the bushing and collapse it in on itself and heat the hole and freeze the bushing to reinstall it
Put part numbers in description as well
Do you know how to get the swing cylinder bushings out? It looks like on my 580SL that they can't be pushed right though because only one end is open where they are installed. Thanks.
Not nearly as bad as my 530ck. Mine has about 7/8" movement up and down, and is ohmost worn through the bushing. Really not looking forward to welding it all back up, and having to run a linebore on it.
where did you get your pin/bushing removal kit
Great video . Did you go with after market pins and bushings or dealer parts.
no doubt a special case tool exists for this. maybe it could be copyed???
What were you tapping on to get the swing cylinder pin out?
Pro tip, put the bushing in a deep freezer for a day. You will thank me for that tip.
I have a massy Ferguson 50D .I need to rebuild the top and bottom tower pins are they about the same
