Thanks as always for your help....
No, because there is no spec for how much they should move, plus these cylinder liners tend to go oval with wear. The proper way to measure piston to bore clearance is to use a bore gauge to measure the bore at the thrust sides and use a micrometer to measure the piston skirt diameter, subtract one from the other.
