M54A1 Posted September 12, 2016 Share Posted September 12, 2016 I need kingpins/bushings for a 1961 B613T with a FA 505 axle. The local Weldons parts guys came up with Mack part #301SQ45A, how ever when I received the kit it is nothing like my original kingpins. The originals have no seals, and standard bronze bushings. The kit contains seals and needle bearing bushings, and the new pins are 1'' to short. What part # is the kit I need? Thanks Jase Quote Link to comment Share on other sites More sharing options...
kscarbel2 Posted September 12, 2016 Share Posted September 12, 2016 Who is Weldons? Do you have your truck's line sheet with the 1QH front axle arrangement ? 301SQ45A is applicable to FA505 axles from 1963 on. Prior to that, you need a 301SQ32B king pin set. Give the folks at Watt's Mack a call (provider of the BMT website). You can reach them at 1-888-304-6225. Quote Link to comment Share on other sites More sharing options...
mmaupin Posted September 13, 2016 Share Posted September 13, 2016 My guess is only the brass bushings need to be replaced. Take your king pins and bushings to a good local machine shop and get them to make you some new ones. Quote Link to comment Share on other sites More sharing options...

terry Posted September 13, 2016 Share Posted September 13, 2016 (edited) Check your posts again, you asked who weldons was and I answered. Different poster is looking for the parts. terry Edited September 13, 2016 by terry Quote Link to comment Share on other sites More sharing options...

I beg your pardon and stand corrected. Too much going on this month. Mike, I didn't step in anything. I did make a careless mistake, and apologize for it, all the while with the good intentions of helping the original poster resolve his dilemma. Recently, there have been quite a few people who posted an information question, and then evaporated into thin air. Sure, we all have things going on. But when you reach out to the BMT population for help, I think one needs to follow up. And though it may be "old fashioned" etiquette in year 2016, a "thank you" from the OP means something to many contributors here. 3 Quote Link to comment Share on other sites More sharing options...

M54A1 Posted September 15, 2016 Author Share Posted September 15, 2016 Thanks for the help with the part numbers. I have waited to post a follow up until I have exhausted all options. There are no kingpin sets for this axle that can be found by anyone. The mack number crosses to several different manufactures of king pins, including Meritor, Dayton, Moog. and Kaiser, non of which are available. One thing that is weird is I have found dimensions of the pin by several manufacturers, and all list a pin that is 6.69'' long while my pin measures 7.375'' long. The shorter pin comes in the 301sq45a set, so in other words the 301sq32b set crosses with many manufactures to sets with the pin which is to short. If there are any other options please let me know. As of now it looks like I might have custom pins/bushings, courtesy of the local machine shop Quote Link to comment Share on other sites More sharing options...
kscarbel2 Posted September 15, 2016 Share Posted September 15, 2016 The cross-over to aftermarket could be wrong by a non-Mack brand. If the truck is year 1961, and the axle is an FA505, then the right kit is the 301SQ32B. When you contacted Watt's Mack, they said 301SQ32B was NLA (no longer available) ? Let me ask you this, how did you determine it's an FA505? Do you have the truck's line sheet with the 1QH front axle arrangement? Also, did you get the FA model and 1QH number off the front of the axle itself? (It's stamped) Quote Link to comment Share on other sites More sharing options...
M54A1 Posted September 16, 2016 Author Share Posted September 16, 2016 I found the axle # stamped on the axle itself, and Watts did say they were no longer available. If anyone knows of a set of kingpins sitting in the dark recesses of someones hoard , keep me in mind Quote Link to comment Share on other sites More sharing options...
