Honing Wrist Pin Bushings

#1 Post by Bill Lawless » Mon Nov 04, 2019 3:43 pm

I probably already know the answer to this ...

Can you hone you own Wrist Pin Bushing? I had one that was a little loose so I put in 4 new brass ones from Stoddard.
Can you hone these or are you at risk of getting out of parallel to the Rod Journals? Or is this a machine shop only task?

Bill
 Thanks,
Bill

Bill,

The .0008 spec is for A/B rods.
