I may do it wrong, but I use a fish scale, hooked to a zip tie around the rod cap, oil the cylinder wall, turn the block so the cylinder tested is level, parallel with the floor. Put the piston in upside down (rod toward me), with only the oil ring on it. Pull it with the fish scale. I do it a couple of times to make sure it repeats. Steady pull. My backwoods Okie method. Gotten by with it for over 50 years. There are likey better ways to do it.

A rep for Speed Pro told me many years ago that their "low tension" oil rings simply had expanders for a.030" smaller bore. May not be that way now. That was probably 20 years ago. I can tell you .060" smaller expanders pumped oil & smoked in my old '56 Chevy Jr Stocker. LOL
