Call jimmy allard in ennis, tx. Allard auto & machine 972-878-9821. He can fix any thing with king pins from sprint cars to big tracktors

 

What do you guys mean when you say the finishes are differant between honeing and the reamer? Are you talking about the gouges the reamer leaves behind when you start the process of reamng the bushings out?

 

just buy an adjustable one. you actually need to ream them to the kingpin so youll need to measure the kingpin with calipers, then setup the reamer(which goes through both bushings at once) and you should do it in VERY small increments, you want the kingpin to be snug and still turn freely, but not super tight or loose enough to be able to move around. make sure your axle hole isnt sloppy either.

 

there should not be any gouges if you are doing it right. always start the reamer MOVING when putting it in. it should be a near perfect finish when done.

when you hone you actually need to squeeze the stones together without touching the sides, then start the hone inside. then keep it moving at all times! then you let it come to a stop while moving still, and when it stops you squeeze them together and take it out again without touching the sides.

 

I think Macks and a couple of old Ford places sell the reamer you need. Synders has one $135. 00. It is long enough to do both bushings. SOMEONE TOLD ME THAT THE MODEL "A" AND ALL OLD FORDS WITH STRAIGHT AXLES ARE THE SAME SIZE. Page 101.You have probably spent that much already with your running around.

This is done by hand. You do not need a milling machine with a power feed.

 

Napa did mine in their machine shop for $30 for both.

 

call a spring shop. any body that makes springs/ does alignments on big trucks can do this. all the trucks in the dfw area it should not be hard to find.

 

+1 on that. And you will get a lot better fit than you would using a reamer.

 

I have my grandfathers old reamer ,clamps in the vice has a long guide so both bushings are aligned and you rotate the spindle by hand to cut the bushing, this is for early fords. A shop with a sun in hone can do any other sizes.

 

The folks at Chadburn make the reamers to a quality that is long established. Having the pilot feature means you can mount the spindle in a bench vise and take several small cuts to achieve the fit. It seems the Ford spec said: a thumb-press fit was desired.

What are the chaft marks that a reamer makes? Not a honing reamer but a old school reamer
