first 500 hours of operation. During normal service, the filter cartridge should be replaced
under the following conditions, whichever occurs first:
As indicated by the fluid filter maintenance indicator when the fluid is at normal
operating temperature
Every 2,000 hours
Every fluid change
NOTICE
The fluid filter maintenance indicator may read high upon start up on cool
mornings due to sluggish fluid creating higher than normal differential
pressures. Monitor indicator after the fluid warms up.
6.4 AIR/OIL SEPARATOR
The air/oil separator is a coalescent filter element. Replacement of standard type separator
requires unbolting and lifting the separator cover and replacing it with a new one. The
air/oil separator should be replaced as indicated in the maintenance schedule or as follows:
If excessive fluid carryover is observed.
4,000 hours MAX (for spin on type), 8,000 hours MAX for standard type, or-as
indicated by differential pressure indicator.
As indicated by the gauge (if equipped).
6.5 FLUID SAMPLING PROCEDURE
The following is a sampling procedure for oil sump without fixed sampling hardware
installed. Check the pressure gauge reading on reservoir and wait until there is no pressure
in reservoir. The oil sample is collected by gravity drain into the sample bottle.
i.
Take sample at normal operating conditions or immediately after shutting unit down.
That will ensure a homogeneous sample of oil.
ii.
Wipe excess contamination from sample area.
iii.
Remove drain plug. Drain any free water that may accumulate at tank bottom
before
filling sample bottle. If system has drain pipe, flush about 5 times the volume of the
dead leg before taking sample.
iv.
Avoid overfilling the sample bottle. Fill sample bottle up to above 80% but below
the threads of the bottle. Seal the bottle tightly, wipe clean.
Pre-label or label sample bottle immediately after filling to avoid mix-ups. Make sure
bottles are labelled with full sample details.
