MH 101 Jr. king pin removal

stevieb49829 · Nov 16, 2022

When I've done king pin and bushings before, there was a tapered bolt running across the axle that held the king pin in place, with a nut to hold it in. All I can see on my front axle on this 101 Jr. is the ends of a pin, basically flush on both sides of the axle. Is this just a pin, that I can drive out? There is no nut, or protruding threads. Is there a small end to this pin, to drive from? steve

I've never been around a 101 JR so I can't guarantee this with 100 percent certainty, but some other MH's (33's, 44's, Colts) have a setup exactly what you're describing, and they use a grooved dowel pin (like those at the link below). There are a few types of grooved dowel pins: center-grooved are slightly larger in the middle, so it doesn't matter which way you drive them out, while full or half grooved are slightly larger at one end, so it theoretically does matter.

I think (but could be wrong) the ones I've done were the center-groove style, so doesn't matter which way you drive them out. Or at least, I didn't really noticed or worry about it when I was beating them out.

Daniel, looking closely at both ends, it looks like the pin has a machined ramp from one end. It would jamb against a flat on the kingpin when driven into place. I'm going to surmise that is the way it works, until someone comes along with a better idea.
