550 Steering Column Top Bearing Kit

JohnnyJohnsoninWI · Aug 1, 2014

I purchased an upper steering column bearing kit for my 550 Oliver and it doesn't fit. The reference part numbers are 1E6779, 1E6780, & 1E6781. It is made for a 13/16 shaft diameter, 1.40" tube ID, and 1/2" cup length.
My tractor has a 3/4" shaft, 1.437" tube ID and a 3/8" cup length. Is there another source for a bearing that will fit my tractor?
Thanks,
John

Are you getting the parts numbers online or from an Oliver parts book?

Those are the correct numbers for a Super 55, I am guessing that they are the same for a 550. I my steering column was in really bad shape so I had to actually weld a Ford lower worm gear onto my Oliver shaft. If I remember right you have to machine the tube a little to get those replacement bearings to seat, but the shaft diameter should be correct. Not sure what"s going on there. I can"t remember where I got my shaft bearings, probably an AGCO dealer. Where are yours from?

I purchased the parts online, however, the local AGCO dealer said they match what he has and I checked the AGCO Parts catalog online, as well.
In the process of rebuilding the steering box, I purchased a second box online, which was of the same vintage as mine and it has a 3/4" steering shaft, too.

As long as you have the measurements, you could try Motion Industriesdotcom.
