Maintenance and operating troubles and remedy
Maintenance involves the usual checks and overhauls common to reciprocating machinery, e.g. crankcase oil level, cooling water system, operating temperatures and pressures, etc. The suction and delivery valves are most troublesome. These valves automatic requiring a small pressure differential to operate.
The constant rapid opening and closing action of the valves may require seats to be refaced. Overheating, use of incorrect lube oil or the presence of dirt may result in sticking or pitting of the surfaces. The suction and delivery valves should be stripped and all parts carefully cleaned and examined and worn parts replaced and the valve seat and plate lightly lapped before reassembly, to ensure a good seal.
