•
Foreign, incompressible material in cylinder
•
Mechanical seizure in running gear (crankshaft, bearings,
connecting rod, crosshead, packing/piston rod, piston)
Cylinder noise or knock
•
Piston loose on rod
•
Piston end clearance improper, piston hitting head end
head or crank end head

Frame noise or knock
•
Loose crosshead pin or pin caps
•
Loose or worn main, crank pin or crosshead bearings
•
Knock coming from cylinder end
•
Damaged crosshead
•
Loose crosshead balance weight
– Excess crosshead to guide clearance

•
Improper lube oil selection
Cylinder or frame vibration
•
Discharge bottle wedges loose or improperly adjusted
•
Compressor frame to cylinder or crosshead guide
mounting bolts loose
•
Bottle/piping acoustical pulsations
•
Drive train misalignment
•
Excessive crosshead guide clearance (crosshead slap)
•
Inadequate support of compressor skid to foundation
•
Loose bolts connecting skid to foundation
– Mechanical problems with driver
– Unequal reciprocating balance weight on opposing
throws
Low oil supply pressure
•
Low oil level
•
Oil pump failure
•
Oil pulsations from excessively cold oil
•
Oil pressure regulating valve improperly adjusted
• Oil filter element – dirty, restricted, or collapsed
•
Defective pressure gauge
•
Oil foaming - high oil level being struck by counterweights
