Baxter Posted October 21, 2013 Share Posted October 21, 2013 Replaced kingpins in one of my RDs and the cap that goes on top keeps pushing out . Have tack welded and still pushes out. Ideas? Quote Link to comment Share on other sites More sharing options...
br549 Posted October 22, 2013 Share Posted October 22, 2013 Were they OEM pins with the 1/2 inch thick plug or the old plugs style about a 1/8 thick? Always jack up front axle to grease. It's possible the grease seal in the top below the bearing is in backward. It should be in so the seal release the grease toward the axle. If its in wrong it holds the grease in and puts pressure on the top cap. 1 Quote Link to comment Share on other sites More sharing options...
jakebrake86 Posted October 22, 2013 Share Posted October 22, 2013 I just changed them on my RD the other day, and the old ones had been driven in, then they hit the spindle with a chisel and created a burr to hold the cap down. I guess if you tack welded it and it's still popping out, though, a chisel won't help... Quote Jake Link to comment Share on other sites More sharing options...

David Posted October 23, 2013 Share Posted October 23, 2013 yes they are the OEM pins with the thick caps, will have to check the grease seals to be sure how they were installed.If they were installed properly, cut a small slit in the seal to relieve the pressure.

rsb502 Posted October 27, 2013 Share Posted October 27, 2013 Might be too small a pin or too big a hole too, pin rubbing top cap if the old pin spun in the axle.

j hancock Posted December 31, 2013 Share Posted December 31, 2013 With the axle number, the correct pin kit can be determined. The axle number is stamped on the pass. side facing front between the king pin and the spring.With the pump number, you can call some suppliers and run the numbers for cost. Called around on a rebuild and found a super deal with warr. from a good shop. Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...

Freightrain Posted January 3, 2014 Share Posted January 3, 2014 B model king pins are pretty easy. Did mine and I've fought with the old Ford I beams version for years. The Mack literally fell out! Took three hours to tear down and that was starting with the truck sitting on the tires to putting the tools back away.I also got my air compressor rebuilt. Mason truck parts:http://www.masontrucksales.com/It was $500 and only took a day. Really fast service. One day shipping, there one day, one day shipping back. Nice work. That was 10 yrs ago?
