King pin bushings

Quick question. Are the king pin bushings for a power king the same size as Jim Dandy? 1 1/2 i.d. x 1 3/8 o.d.? Would replacing with bearings give any added benefit?

Re: King pin bushings

Just bushings in there. McMaster Carr or othe places should have them. Bore in axle has a step on some so have to drive them out each way to remove. IF you have worn thru the bushing and actually worn into axle, new bushing might just push out in space there. Bearings?? Not sure what you would use. Needle bearings? There is a thrust bearing on bottom outside of the axle. Would replace all of them. Would think new bushings and thrust bearings would take care of any tight steering. These don't steer hard at all. AND, center swivel bearing on axle beam is same bushings too, might replace them and get rid of more slop if that is the problem.

Re: King pin bushings

Thanks for the reply. I actually did some damage removing the bushings. I could reuse them but figured I should just replace them while I have it apart. I had needle bearing in the front arm so I thought I could just use them for the king pins. They are bearing number B-1618 if I remember correctly ( I will confirm that in the morning). They are $10 each. If there would be no real benefit of using the bearings I'll just save the money and use it elsewhere. I found brass bushings and the bearings on eBay so all I need to do is order them.

Could you or anyone else give me info on the thrust bearings? They still run smooth enough but I can hear grit in them. Are these sold as one piece or do you open them up and replace rollers inside? Any idea of a bearing number?

Thanks for the help! I'm just trying to get past this point so I can get the rolling frame pics for my restore thread.
