Three cylinder radial configuration for balanced and effective cooling operation

1. Head unloaders for continuous run.
2. Dependable, accessible, and efficient disc valves increase service life and serviceability.
3. Graphite gaskets offer superior sealing against high temperatures.
4. Precision honed cast iron cylinders.
5. Two-piece forged steel connecting rods.
6. One-piece cast iron crankcase provides durable and smooth operation.
7. Oversized ball or tapered roller thrust bearings on both side of crankshaft for long operation life.
8. Oil sight glass for quick and accurate lubricant level reading.
9. Intercooler further reduces inter-stage air temperature for maximum compression efficiency and valve life.
10. Copper finned discharge tubes help reducing inter-stage air temperature.
11. Counter weighted large diameter crankshaft provides smooth operation and longer wear.
12. Replaceable journal bearings extend rod life and simplify service.
13. Oversized flywheel delivers high flow of air for cooling.
14. Step-type compression and 3-piece oil control piston rings provide improved leakage and oil control.
