King Pin Reemer
I recently purchased a king pin reamer on eBay, #113067150199 which is NOS KR Wilson. I collect old tools and always wanted one of these. It does appear to be NOS, no rust and mine came factory wrapped in an oil paper. It is marked KRW 1 006, K6. It has a square drive at one end.
My questions are: The cutter is in the middle, how do you accurately support/hold the cutter while reaming a bushing? Is the end of the reamer in a bushing while you are cutting the other bushing? What are you turning the reamer with, a tap holder? What is the procedure to obtain a smooth clean cut? What kind of lubricant is best to use while cutting? Thanks for your help, Ed |

Re: King Pin Reemer
Post a photo, Maybe there is a youtube video about reaming. the reamer needs to be supported through both bushings. I prefer to have these bushes honed, then you start out with a closer tolerance that wears slower than reamed ones do initially.

Re: King Pin Reemer
1. Yes, press in new bushings. Reamer will fit through the uncut bushing and act as a guide for the bushing you are cutting.
2. I use a small 6" adjustable wrench. Never try to "power feed" 3. The reamer will do the work for a smooth cut. Go slow. Don't try to force the reamer thru the bushing.. just let it slowly cut. Apply slight pressure with your thumb on end of reamer. NEVER turn it backwards, but do clean out the shavings. 4. I use a dark thread cutting oil. Note: I have reamed a fair number of bushings with these reamers. The fit will be slightly looser than having them align honed, but I have never had a problem with excessive front end play or shimmy after reaming. Good luck ! PS.. I always have extra bushings on hand |

Re: King Pin Reemer
Did you notice the reamer size was 1.006". Too big for Ford cars and light trucks? Must be for the really big trucks.

Re: King Pin Reemer
a normal king pin reamer has the adjustable reamer body then an adaptor that screws on to opposite end of the square drive then there is a tapered sleeve that locates over the adaptor and then into the second bush to do a perfectly inline ream , the king pin should be lightly oiled an be able to slide thru with a small amount of force ........OH and the axle and the stub should be shimmed in the vertical plane to take out all traces of movement
I have repaired countless stub axles doing it the correct way because of so called shoddy rebuild jobs by others Yes you can do it with a tap holder ( I use a lathe ) Yes ....use a light machine oil cheers Steve in Oz |

Re: King Pin Reemer
scar is 100% correct. I have see countless people press in their bushings and first ream one side and turn the kingpin over and do the second. You will never get perfect alignment that way. You should always use self aligning reamers. Yes, they are costly, but they do the job the right way.

Re: King Pin Reemer
I was taught to only turn the reamer in one direction and that is the direction of cutting. Do this even when extracting the reamer as some reamers will not pass all of the way through the two bushings.
