Measure cylinder walls for taper, out-of-round or excessive ridge at top of ring travel.

This should be done with a dial indicator or inside micrometer. Carefully work gauge up

and down cylinder to determine taper and turn it to different points around cylinder wall

to determine out-of-round condition. If cylinders exceed specifications, boring and/or

honing will be necessary.
