Hello, I am reassembling my MD-11 and one part just doesn't make sense to me, with new liners and pistons, a measurement from the top of the piston to the top of the liner is required, to be changed by shimming up the water
jackets. I don't have access to a dial indicator for this measurement, and besides, the clearance is so much greater than the measurements that I can't see how it would make a difference. Any thoughts? Thank you.
