Hi everyone, I'm in the process of fitting a new king pin set for my 1956 olds, and I need some help. I bought the manual and in it, it's says I need to BURNISH then LINE REAM TO SIZE the bushings.
My problem is that I don't really understand what that means (my mechanical vocab in english is not that great as i'm french).
So in short, can someone explain my in plain and simple english what i need to do please.

So nobody to help me improve my english/mechanical knowledge?

Sorry, I don't know. Let's send it to the top of the page and see if anyone can help you.

 

Educated guess but I would say the bushing ID is way under size and will need to be reamed ( fancy name for special super high tollerance drill bit )
Its basicly a machining opperation and should be left to a pro. A fixure will be need to made for the upper and lower hole excatly in line with each other and reemed to a specific clearance.

 

The kingpins are usually about 1" in diameter (+/-).The bronze bushing supplied with the new kingpins are pressed into the spindle and then honed to size for a press fit. I took mine to a machine shop, they pressed out the old bushings, and pressed in the new ones, then honed them for fit. Cost was $20. "Align bore or Align hone" means they do both the top and bottom at the same time to assure that they line up so the king pin will go thru both without damage.

 

you can get an adjustable reamer with a guide on one end to keep the reamer straight,we use then in the truck shop that I work at,as for burnishing I don,t know how you would do that on a steering kunckle,burnish means to rub the metal with another peice of metal to harden and true up the surface, smaller holes can be burnished by driving a ball bearing, that is a couple of thousands larger then hole,through the hole,Best to do has OLDBILL did take it to a machine shop. if you do it yourself and ream too much off you will need to replace your new bushings,
