MAINTENANCE PROCEDURE,TEST AND MEASUREMENT.

All operating cylinder valves inspection should be performed with an instrument such as feeler gauges,in accordance to specification and should be replaced with spare parts where test is unsuccessful or unsatisfactory.
-Adequate inspection should be conducted on journal bearing for wear,crack,pitting,using appropriate instruments,(micrometer,dial, vernier, internal micrometer,external gauges and dial gauges,comparator etc) with an accompanied data plan that could details their operational interval,such data are evaluated to determine their operational lag and performance..
-Malfunctioned devices or instrument should be discarded to eliminate re-usage hence avoidance inconsistent maintenance operation.
-All connecting rods/gudgeon pins, end caps should be inspected to specification
-A metrology/measurement should be conducted on the crank rods/ancillaries,and other malfunctioned items should be replaced
-All component and materials received for the maintenance of machines should be carefully inspected for quality,machining error,defects and other shot falls in accordance to API 1104,or ASTM.
-All actuators and valves (ball and gates) with prismatic operated devices,including relief valves should be maintained, inspected,and  calibrated.,other faulty devices be kept to standard through adequate re-calibration and in accordance to oil mineral code 1963 and BS code 229
