Hi
does anyone have handy the proper piston pin bushing bore tolerance for a "48 farmall M (1.3125 dia pin)?

Thanks!
 
From near nothing , but will move if rocked on the rod gently, to .0005" I would run it if it had .001" but it might make noise. Jim
 
From 3 to 5 ten-thousands. You will need the gauge on a pin-fitting machine to check them. If you can feel any looseness they should be replaced & fitted.
