1988 -520H

Hi, I have a 520 H that the steering wheel was not center with the front wheels, I was able to center it by turning the wheel then slipping the steering shaft gear past the other gear. I see that it is worn, either the steering shaft or the lower support block. My question is has anyone ever attempted to fit a bushing into either of these parts as a repair or am I better off replaceing the parts .

Hello wheelhorsejoe,

I just installed bushings in my 520-8 lower support block last week. Here is picture of the original.

The steering shaft hole was worn oversize left to right more than .050". I machined and installed both bushings (.750 I.D.X .875 O.D.) purchased from McMaster-Carr.

I also added the grease fitting to the bottom bushing.

Hope this helps.

Yes, you answered my question. Did you use a steel or bronze bushing? Thanks Joe

I used the bronze SAE 863, which has more iron in it. The bottom bushing is 1/2" long and the top is 3/4". The I.D. tolerance is 0 to +.001", and the O.D. tolerance is +.001" to +.002". Part #'s 2868T167 and 286T169, they were only $1.28 each, so I ordered two of each for the next time, but the shipping was a little more than the total of the sleeves.
