  • King Pins and Bushings

    In the next couple days I'm going to be fitting my king pins to new bushings. I'm not sure what the clearance should be. Anybody have an idea what the specs are on that? Here's another question. I noticed the upper thrust bearing was on what looked upside down. Both sides were that way and as far as I can tell nothing has ever been done to the front axle. I can post a picture...

    I always have mine honed for a perfect interference fit

      Ok I'll go along with that. But what do you consider a perfect interference fit? Just enough the pin goes in without forcing it?

        Yep, about like the piston wrist pin with a .0005" fit.

          Ok. That's what I thought but wanted to make sure. Been a long time since I've done car or pickup pins and bushings.
          Thanks Mitch and Tom.

            I think the advice given above is all very sound. My only addition to this is "Don't leave the bushes too tight" The car will be all over the road if they are. You should be able to turn the pin in the bush with your hand but not feel any play. I lapped mine in using the part of the old pin that was in the axle. I prefer this way as a hone only follows what it there already and will not leave the hole any more round than what ever preceded it (reamer?)

              Ok I finished em up with a .8125" reamer and did the last step with a light touch up with a hone. Pins went in fine turn by hand nicely and no side play.

              VFFVFFVFFVFFVFF, I think a .814 would have been a bit too much but everybody has their preference. I looked at Amazon going through page after page and came to one that was the last one left. It has 8 flutes, .8125" dia., and was priced at $10.31.

              I made my own fixture to keep the reamer centered and straight in the bushings. It is not the same as the vendors sell. Not saying theirs is not any good, just that I saved quite a bit and I am very happy with my results.

                You're right about that, cost too much. Too bad they can't be rented. All of the material I used for mine were salvage pieces of metal. Sometimes it pays to hang onto some of that junk.

                  Dennis,
                  Haven't been on in a while but....Hopefully you got this done but if not I would try to find a local machine shop with a pin hone.. sunnen variety or otherwise. I have one in my shop and it is indispensable! Couldn't do what I do or nearly as well without it. As tom said a .0005 fit is good.

                  I use them for brake shaft, spindle bolts, any bushed and fit shaft and bushings so they have a good smooth tight fit.

                    by Cape Codder
                    Can someone tell me the clearance for the King Pins when installing new bushings? I don't know if there is a standard clearance needed or is this measurement just to the Model A Ping Pins....

                    New one on me. Im rebuilding (not restoring) a front end and on dissasembly noticed the lower cup didn't have a felt in it. Well incleaning up the king pin I found it, and the actuating pinfelt. they were both on the bell of the king pin.

                    Kin Pin Locking Bolt and Front Axle
                    by dmdeaton
                    Ok, 1 more dumb question tonight and I will leave everyone alone. The new king pin locking bolts wont start through the axle. I thought the holes might be tapered, and the axle is installed backwards, but the locking bolts are not tapered. I am guessing I just need to ream or run the proper size drill through the holes to clean them out?

                    King pin, as in one
                    by carolinamudwalker
                    I received the spindles from the estate sale and I am having new bushings pressed in. The venders will only sell the king pins as a pair. Would anyone have a single they would part with? We have signed up for the Rout 66 tour and will be covering between 6&7 thousand miles, half of it solo and would like to carry a spare. Thanks...

                    by canadian
                    looking for advice on king pin repair/replacement. 1929. Have noticeable movement in both left and right. Is it common for bushings to wear and pin be ok? Is there a complete overhaul kit available ? Can this be performed at Home Shop or Definitely a Machine shop? Reason for asking is parts availability is non-existent for me ,everything has to be ordered and time frame is sometimes longer because...

                    King Pin Retainers
                    by Mach.8
                    My king pin retaining pins/bolts have been installed backwards. They were inserted from the rear of the axle and the nut/steering stop is on the front. I became aware of this when the inside of my left front tire rubbed on the brake rod during a tight turn. I figured I could just remove them and reinstall in the proper direction. I removed the nut and lock washer, reinstalled the nut loosely with...

                    by Poor Boy
                    I have the front end all apart on my 31coupe and am in the process of repairing loose steering. I have new king pins fitted but not yet installed. I find myself doubting what I am doing and second guessing myself. I have been referencing Les Andrews red book and for the most part it has been very helpful. He is very specific about the orientation of most parts, but doesn’t address the felt and...

                    by Cape Codder
                    Why am I unable to find the answer to my question when I'm sure I have already read it?
                    What is the diameter of the hole in the axle for the King Pin?

                    I have used the search with different wordage with no results!

                    King Pin Kit
                    by Beauford
                    If you purchase the Kingpin kit from the two reputable sources, the felt cups are too big. If you search to buy individually felt cups they state that these are machined to the correct size as the others were bigger.(I'm certain the bigger ones are in the kit) I was putting in pins last night and with the kit felt cups and felt it will just wedge and mangle itself trying to align the spindles. Just...
