Dimension Help, Please

[Ihncheol Park]

That's very interesting.
Because based on the dimensions supplied by YS 140L manual and OS manual, OS
is 2 mm longer from front mounting holes to the face of the drive washer.

Bob:

I think Gerald is right.  I replaced my old YS 140 FZ with an OS 140 RX
and the OS was a little shorter.  I was in a hurry so I installed a
flat washer behind the spinner plate.  You will need to replace the
nose ring.

The OS 140 RX was in a Focus. I installed a 3M 140 and they are exactly
equal.
