1940 Buick S90 Limited King Pin Reamer needed

[Guest pauldridge]

I purchased new king pin set from Kanter for my '40 series 90 limited.  My suspension guy (and confirmed by the manual) thinks a reamer is necessary for the king pin bushings when installing.  The king pins on the S90 are 1.06" diameter, roughly.

 

Can anyone suggest a source for such a reamer (or has one to rent or loan?)

 I've done this two ways, first time I made a smaller pilot pin out of an old kingpin, and used a compound to lap the bushing to size. Tricky to get it right, but I did, though time consuming. Next time, I bought an adjustable reamer from a machine shop supply place, set it up, and reamed to size. Worked perfect, and way easier than my first method.

 From time to time, I have seen reamers that are made to the correct size for these pins, but I do not know where to get one.

 Hope this helps!

I used a reamer for brake cylinders to do mine.

I used to just take them to the machine shop. I'm not sure if anyone does them anymore.

Call around to various repair shops and you will find someone who has a set of King pin reamers and will do them for you at a reasonable price.  I had my suspension off the car and carried them to the man who did a beautiful job of sizing them.  You not only need the reamer, but also the guide bushings that come in the set.  An adjustable reamer will also work using the 2 bushings simultaneously to keep the reamer straight removing little metal at a time until just barely a slip fit.  You can use a cylinder hone to do the final slip fit if necessary.

Keith,

        McMaster-carr sells adjustable reamers.  I have one, used it several times.
