I have the king pin lined up in the spindle, but it is awfully hard to drive the lock bolt in. Might it be that I just don't have the strength that's needed? Do I need to get the neighbor guy?

Does the kingpin have the flat spot for the lock-pin in the center (top to bottom) on the kingpin or is it more toward one end ? I do a lot of them (kingpins) and do not remember haw each one is machined (I would go nuts

Lightly hammer on the lock pin if it won't budge make sure the inside race hasn't slid down just a hair.
Change mine a year ago and had to lighty tap to get them to go thru. Guarenteed you want them tight.

Dont use a bigger hammer. It should,t take much to get it most of the way & then draws up with the nut.

How does the dia of the lock pin compare to the hole in the axle . ?
Any burrs evident ? | | |

Try turning them upside down from their present position, and see if the taper works better.

It is quite long, much longer than the pin width. The pin is round and has a flat side with maybe a very small taper to it. The pin should go in to where the threads are showing through. Then some light tapping should move it more to be able to use the threads. You don't want to hammer it hard, that would be a big mistake.
If the kingpin is off by just a few degrees, and it is tight, you can have a problem like this. The hint about the tapered drift is a very useful thing to try. | | |

how did your old pins come out, drilling or tapping? If they came out in 1 piece, it may be of interest to try them for fit. | | |
#38660 09/13/2004 4:34 AM | Joined: Nov 2003 Posts: 117 Member | | Member Joined: Nov 2003 Posts: 117 | I tapped them out, but they were trashed, as the "taps" were none too gentle.
I do have some shorter lock bolts from a 53/54 Chevy car. Does anyone know if the circumference is the same?

is there a chance that there is a slight distortion at the opening where the threaded end should emerge? To check for this, if you insert the pin backwards, that is back to front, the results should be identical.
Also, if you are very close to success, putting the pin in the freezer for a few hours may help. | | |
