King Pin Reamer what size

[oldmopar]

1st I should reference my previous post about the bent tire rod as was suggested it was not to hard to straighten. It may not be perfect but as good as some pool cues I have used.

I noticed some play in the left king pin and it may need to be replaced, from what I read they need to be reamed. I have some reamers in a box but need to know what size.

Its a B1d 1 ton if they use different sizes

Oldmopar-having done my own 1 ton axle a few yrs back, the process was to "remove the old pins" (sometimes easier said than done) and then with a set of new pins in hand fit them into the axle eyes to make sure that they fit snugly and done wobble or move in the eyes. If thats how they fit, your good to go-if not the eyes need to be trued up and oversized pins used. If they do fit snugly you'll need to have the new bushings that come with the pins pressed into the spindles, and then have them reamed to fit the new pins. The size reamer will depend on the difference between the OD of the new kingping, and the ID of the new bushings. What I did was to fit my pins to the axles, and then took the spindles to a machineshop to have the bushings pressed and fitted to the pins. If I remember correctly the price of the parts was about $50, and the machine work about $25, but its been awhile. Mike

Mike, after reading your reply I guess the best thing is to knock out the pin and see just what I have . Cross referencing the old mopar part # at NAPA comes up with a set for about $120 I have I do have a press not sure about the reamer. I will check out the price of getting the bushings done as I have more then enough work to do. The right side feels ok but the left has more play then I would like of course I just finished doing the brakes and felt this while I was putting the drum back. Or maybe just wait and road test it and go from there as have some more work to do on this truck and need to get another vehicle into the garage soon. What I really need is more garage space but I guess that is a problem we all have

I've done 2 recently, a 40 dodge car and a 47 dodge 3 ton. Paid about $50 for the car kit, paid about $125 for the one for the 3 ton, but that was from Mitchel (sp?) Motors, and they're usually double.

Paid a local machine shop under $25 each to install and size both.

NAPA at lest by me is not cheap but usually good quality stuff. That was the price on the website I used the original part # and the napa part # (NCP 2621231) and price came up actually I think $112 but I added the tax 7% here. From what you and Mike quoted price wise it does seem to make sense to let a shop do the bushing and save the sweat and aggravations for another repair.

You don't really need a kit, just bushings and welch plugs, the pins, and shims are re-useable. You can get the bushings at any good bearing house, and NAPA has the welch plugs. My reamer is 52/64".

[austinsailor]

The kit is $55 at Bernbaum. Even if something is a little higher I usually go to Napa just to support them, as they help me a lot. But more than double is more than a little. I've gotten a king pin kit from him before and it was correct. Some don't like him, but he knows exactly what part is needed, usually has it in stock and ships the same day if it's early.

I did get a wrong part once, not really his fault, but he took it back with no hesitation. As they say, just my 2 cents worth.

Ed-you're going to have to look and see what kind of shape your pins are in once you get them out before you can make a decision as to whether you just need bushings. If they get mushroomed from pushing (beating) them out, or if they're pitted or worn they'll need to be replaced. Mike

I will pull the pins 1st that way I can see just what I am dealing with and go from there. I have been pricing the pins and see Roberts has them in their catalog for $55 and them owe me $50 for a core deposit so that is the way I will most likely go. The big decision is if I do them now or in 6 months. I am in the process for trying to figure some noise in the pto (dump truck 4 speed trans) drained the trans yesterday so I can remove the pto for a look and still have and have some work to do on my 62 willys that I use to plow snow of course if it does not snow any more I am ok

If your King Pins need replacing

you grab the wheel when its jacked up and see how much play is in the wheel rocking it top top bottom. You may want to tighten the wheel bearing to be sure its not what you are feeling ,back it off about 1/6 of a turn when done. I think the manual states something like 1/8" of play but you just go by feel it it feels too loose it is.
