Old tool questions

[[email protected]]

Hi everyone

Anybody have any idea what kind of tools these are?
I was thinking old tractor clutch tools.....

I'm in the middle of cleaning my grandpa's old barn and these are the first tools I can't figure out...

Last one is an adjustable reamer.

They are all reamers. I would bet that the first and third ones have a screw in one end that pushes a tapered pin to adjust them.

I believe that the first and third are king pin reamers for steering axles. The long part ahead of the spiral cutting edges is a pilot to hold it in alignment .

All of them are reamers. Someone must have replaced a lot of bushings in that barn!

Sigh...Go figure I need drill bits and sometimes I have to take whatever is in the box and sometimes I end up with reamers which is ok with me; only wish the box was filled up with hard to find items that I am always looking for!

Anyhow a box of reamers:

#1 and #3 are most likely the king pin reamers as noted above. #2 is just a standard reamer, and #4 is an adjustable reamer with replaceable blades

Yep, adjustable bushing reamers. I used the HD truck version on Peterbilt and Kenworth front spring pin bushing jobs.
