Answer / iftehar hussain

With reference to the engine manf. tolerances and record sheet, using a calibrated micrometer. Bottom end bearing is removed from crankpin / piston removed. Surface wiped clean. Then at the specified points in the record sheet, measure the diameter. Normally at least 0, 45, 90, 135 deg. with ref to TDC and 5 equal distance locations across the pin.
