FuzzFace2 Posted March 13, 2018 Share Posted March 13, 2018 I have a few questions on kingpins, spindles & beams. I may know the answer but want to make sure. Has to deal with 80-82 F100/F150 4x2 trucks with king pins. (Mine is an 81 F100) I know there are 2 different size king pins and they seam to be based on power & non-power brakes. Non-power brakes have the larger dia. pins I know between power & non-power brakes the wheel bolt patterns are different. power = 5x4.5, non-power = 5x5 I know between power & non-power brakes rotors / hubs are different. I know between power & non-power brakes the spindles are different because I tried to swap rotors / hubs and find this out. Now what I am not sure on: Are there 2 different beams because of the king pin size based on power / non-power brakes? Any one know the OD of the king pin bushings for the 2 different pin sizes? Or know the ID of the 2 different spindles where the bushing get pressed into? What I am looking to do is use the small king pin kit, small king pin beams and the large king pin spindles so I can run the 5x5 wheels. That is if the small pin bushings will fit / work in the large spindles so they can be mounted on the small pin beams. Anyone know?

Gary Lewis Posted March 13, 2018 Share Posted March 13, 2018 Dave - Are these forged or stamped beams? I'm not sure I need to know that, but it looks like I will. Anyway, I'm researching it........ Link to comment Share on other sites More sharing options...

Here's what I am seeing. What I now need to do is go to the parts list, meaning 30.1A, B, D, E, or J and look at the components. But I need to know what you have, so can you tell me which row(s) you have. Then I can look. Link to comment Share on other sites More sharing options...

I would like to mount the non-power brake large pin spindles on the power brake small pin beams using the small pins if the bushing will press into the large spindles. If someone had both pin kit and could measure the OD of the bushings I think that would let us know if it would work. Dave - - - - Link to comment Share on other sites More sharing options...

Dave - - - - Dave - If you have both spindles can't you measure their ID's to find the OD of the bushings? In any event, with the following research, you are looking for the OD of bushings D5UZ 3110-A and -B. From the following, forged axles get parts lists of 30.1A, B, or J. But "J" is for a 1983 or later truck, which will have ball joints. And to prove that 1983's have ball joints, see below where it says 30.1 A & B don't require a Joint Assy (Spindle Arm), which is a ball joint. And, farther down it shows that "J" does get a ball joint. Ok, then look at Bushing and Pin Kit (Spindle) and you'll see that "A", which has power brakes, gets pin kit D5UZ 3111-A, and the "B" axles, which have manual brakes, take pin kit E0TZ 3111-A. And, here are the contents of those two kits, including the bushing part #'s: Link to comment Share on other sites More sharing options...

But were also used in lots more applications as well. However, notice that the wall thicknesses don't appear to be all that different. That suggests that their OD's are different as their ID's certainly are. Link to comment Share on other sites More sharing options...

The thing is I don't have the proper device to muasure with and with the new bushing in the 1 set I don't know if I would be able to measure them right. I will look over the large pin spindles to see if I can get a measurement. Don't want to take the small pin set apart if I don't have to. I have seen I think the small pins used on older trucks when checking auto zone. I will let you know what I find when I get to this part of the project.

We can pick this up again then. I think I left enough tracks that I can get back to where I was. Link to comment Share on other sites More sharing options...
