ggdad1951 Posted July 9, 2010 Report Posted July 9, 2010 ok, I'm scratchin' the ole noggin here....I can't find anything in the old posts (or I don't know how to search them properly) I went to NAPA, looked up a kingpin rebuild kit via the truck serial number and came up with PN 262-1451. It HAS the right parts for the most part as well as several extra parts. I have two questions, one philisophical and one practical. The old bushings in the king pin are copper and nice and fancy, the rebuild kit comes with plastic...do I pound out the copper and replace with the plastic? I slipped the new kingpin in and little to no play, since I'm in there tho....thoughts from anyone on this? on to the practical question: there is a bearing in there, the rebuild kit did not come with one, I'm going to NAPA tomorrow to see if they have it, or should it be in the kit?

MBF Posted July 9, 2010 Report Posted July 9, 2010 Been there done that. I'd take the spindles to a machine shop with your nylon bushings and have him press out the old brass ones and press in the nylon ones so that they can be reamed to fit the king pins. Im pretty sure the thrust bearings are going to be needed to make the spindle fit correctly on the axle eyes regardless of the bushing materials used. I don't think there should be any play between the pin and the axle eyes, but I had a tiny bit in mine when I did it about 15 yrs ago. I've heard stories by some that the nylon bushings last longer than brass, and the other way around too! Since these trucks aren't being used like they used to be it shouldn't make a lot of difference. If I'm wrong, someone will correct me here. Mike Quote

Mike Actually was told with the nylon you didn't need any reaming...advantage of those. The bearings should be done now once you've gone that far, but if unavailable and your have zero play then no real reason to HAVE to do it. I noticed when I looked at the kits the nylon kit didn't have the bearings, there was the standard with with brass that did, but there was 2 bearing options, the "friction bent washers....no idea the correct name" and the ball bearing...but that may depend on model and year as to whats right.

Dave72dt Posted July 9, 2010 Report Posted July 9, 2010 The bronze bushing type will definitely need to be sized after install. As far as thrust washer type vs ball brg, I've got to believe that turning will be easier when the load is supported on a ball brg than on a washer. Should also mean less wear on the bottom of the axle. Quote
Merle Coggins Posted July 9, 2010 Report Posted July 9, 2010 Napa has several different king pin kits available. Some have bronze bushings and some have nylon bushings. Some have thrust bearings and some have thrust washers. I would return the nylon bushing, thrust washer kit and get one with bronze bushings and a bearing. Merle Quote
ggdad1951 Posted July 9, 2010 Author Report Posted July 9, 2010 thanks guys! REALLY appreciate the help for this novice here! I got the parts and reciept and will hit up NAPA armed with this new knowledge over the lunch hour! And here I was hoping I'd be able to put my first parts back toegether last night! Quote
NiftyFifty Posted July 9, 2010 Report Posted July 9, 2010 I wouldn't rush to take back the nylon, was told that there the best bushings, wear way less then the brass....this is from a 30+ year mechanic. Quote
ggdad1951 Posted July 10, 2010 Author Report Posted July 10, 2010 well, to get ALL the parts I had to get two different kits from NAPA, one didn't have the bearings and the other didn't have the bolt lock...what a racket! But now I can choose between the brass and the nylon since I have BOTH! Quote
ggdad1951 Posted July 12, 2010 Author Report Posted July 12, 2010 anyone have an idea of where to by a reamer for the bushings? Quote
Dave72dt Posted July 12, 2010 Report Posted July 12, 2010 Fastenal, Mac, Snap-on, Matco comes to mind. You might even find one at your local Harbor Freight. You can probably have a machine shop fit the pins for less than you can buy the reamer. Quote

Young Ed Posted July 12, 2010 Report Posted July 12, 2010 You are at the wrong end of town. I know a great shop if you want to drive to Blaine. Quote
ggdad1951 Posted July 13, 2010 Author Report Posted July 13, 2010 (edited) You are at the wrong end of town. I know a great shop if you want to drive to Blaine. What's the shop's name? Would they do it while I wait? The gf lives in Mounds View. And driving is no big deal. Friday I hauled the rear diff from Circle Pines to Zumbrota! Edited July 13, 2010 by ggdad1951 Quote
Dave72dt Posted July 13, 2010 Report Posted July 13, 2010 You'll may have your best luck at "do it while I wait" if you call ahead and schedule it for right after lunch or a scheduled break period so they don't have to stop in the middle of a project, do yours a nd then go back to what they were doing. Being there on time (early) is a given especially if you may have further need for their services down the road. Quote
Young Ed Posted July 13, 2010 Report Posted July 13, 2010 Adelmann engines in Blaine. You'll have to call and see if he can do it while you're there. I dropped mine off after work one day and picked them up the next. Quote
ggdad1951 Posted July 13, 2010 Author Report Posted July 13, 2010 ok cool, and thanks again, I take Friday's off all summer so I have some time to "kill" and do stuff like this. Seems this year Fridays aren't for biking and lazing in the hammock, but for driving and cursing at old truck parts! Quote
Young Ed Posted July 13, 2010 Report Posted July 13, 2010 Stop and soak in some of Toms knowledge. He's an excellent engine builder. To him a flathead is a modern engine. I've seen Packard v12s in there, he did a guy I knows Whippet engine, stuff from the teens and 20s all the time. Quote
ggdad1951 Posted July 13, 2010 Author Report Posted July 13, 2010 (edited) heh, sat onthe phone w/ him for 20 minutes this AM, will be stopping by soon and sure feel he'll have a wealth of knowledge, he's already turned me on to other vendors I needed to find for other work! thanks for the contact!
