MAINTENANCE
5.10
AIR/OIL SEPARATOR
Replace the air/oil separator every 1,000 hours, annually, or when differential exceeds 10 psi. The air/oil
separator employs a unitized element.
The separator element is a single piece unit, which requires replacement when it fails to remove the oil from
the discharge air. Prior to replacing the separator element be sure to check the oil return line and orifice for
plugging or restrictions.
WARNING!
The combination of a build-up of dirt and oxidized oil can clog the element causing an increase in air
velocity at narrow points on the element media. Elevated temperatures at these points can result in
ignition of the fluid in the oil sump.
5.10.1 REMOVAL
1.
Relieve sump pressure to zero pressure.
2.
Unscrew air/oil separator element by turning counter-clockwise.
3.
Remove the old element and discard in accordance to local codes.
5.10.2 INSTALLATION
1.
Apply a thin film of oil to the seal of a new element.
2.
Thread the element on by hand, turning it clockwise until the gasket seats. Then turn an additional
¼ turn by hand.
5.11
THERMAL VALVE
Inspect and clean the thermal valve if the unit shuts down because of high compressor discharge oil
temperature.
5.11.1 INSPECTION
Inspect the valve by removing it from the manifold housing. Sediment particles may lodge in the valve-
seating surface and prevent it from opening, thereby allowing hot oil to pass directly to the compressor
without being cooled.
5.12
OIL COOLER
The interior of the oil cooler should be cleaned when the pressure drop across the cooler at full load exceeds
25 psi.
5.12.1 INSPECTION
Inspect compressor oil system for signs of varnish.
5.12.2 REMOVAL
1.
Drain compressor fluid.
2.
Remove oil cooler.
5.12.3 CLEANING
Circulate a suitable solvent to dissolve and remove varnish and sludge.
5.12.4 INSTALLATION
1.
Replace oil cooler and fill compressor with fresh oil.
2.
Operate the machine normally for 50 hours. After 50 hours, change compressor oil and install a new oil
filter element.
5.13
GREASE
Use a multi-purpose type grease (MKG) or multi-purpose type grease with molybdenum disulfide (MPGM)
conforming to MIL-L-7866 for all parts except wheel bearings. Use wheel-bearing grease (WBG) for
lubricating the wheel bearings.
5.14
ENGINE LUBRICATION
Refer to Engine Operation and Maintenance Manual, located at www.kohlerpower.com for recommended
engine lubricating oil, service intervals, and maintenance practices.
