This seems to be a well used topic but I figured I would put my two penny's in anyhow. Today I went out to the garage bored and saw the b-10 setting there with the blower looking lonely so I went over to play, the steering has always been an issue and today is the day to fix things. upon taking it apart I have discovered there are allot of worn out and bad parts.
To be fair I have had this apart once already do free it up, so the bearings where still ok this time. the bushing for the steering gear is worn down and the holes for the steering wheel cross bolt bushings are worn out. Looks like I have some work to do, going to make an new bushing tomorrow. probably just do a weld buildup around the holes and re-drill them the rite size.
as for greasing the bearings (there is no way to do it ) I am going to drill up the center of the steering shaft then cross drill, once that is done I will tap for a grease fitting on the bottom so I can grease the bearings from under the tractor anytime I want.
I will get pics as I go along.
