4430 Load Control Shaft

Rich.Fl · Feb 3, 2016

I have a 4430 that was leaking badly from the load control shaft. I have the shaft removed (it was badly worn) and have a new replacement shaft and new bushings.

My question is...how is the best way to remove the bushing?

Thanks!

I put the shaft back in and leave about an inch sticking out of the bushing then weld the shaft to the bushing. Then drive the shaft and bushing out. Then I cut the bushing off, turn the shaft around and do the same to the other side.

Square off the end of the old shaft and use it to drive out the bushing from the other side. There is not a lot of the bushing to catch from the inside but a good edge on the shaft will usually catch it. If you have help, have them use a screwdriver to hold the end of the shaft off center so it does not slip through the hole in the bushing.

Agreed

I pried one of the seal gaskets out then you get a little more room to angle the old shaft to catch the bushing on the other side.

Thanks all for the excellent information!!

I got the bushings out today

I liked the suggestion of welding the shaft to the bushing but I only have a little MIG welder and the tractor was in a barn without power. So I cut the end of the old shaft square as suggested and was able to get the bushings out without much trouble. There was enough play in the worn bushings and shaft that I was able to get the end of the shaft on the shoulder of the bushing without removing the seal...another suggestion I liked. I could reach over and feel the end of the shaft on the bushing very easily so I knew I was in the right place before using a 2 lb hammer with medium force to remove the bushing.

My next question of course...any tips on putting in the new bushings? The service manual talks about "Chilling" the bushings. Any reason not to put them in the freezer tonight?

Also the best way to drive the bushings in?

Thanks Again!

I like the idea of freezing them. Thats what I do with bearing races and it has always worked well for me. That and a brass punch to tap in place. Good luck

Ditto on freezing the bushings is a good way to install them
