6.15. Lubrication Oil
6.15.1 Compressor Oil
The correct oil for compressor lubrication is a quality turbine oil, containing rust and
oxidation inhibitors and corresponding to ISO VG 68. DO NOT mix different brands or
grades of oil. The compressor was initially filled with
fully-synthetic
76 Products
Company turbine oil ISO VG 68 having a viscosity of 336 SUS @ 100
°
F (38
°
C). If the
need arises to add oil and this brand is not available, drain completely and refill with a
suitable replacement.
DO NOT MIX OILS.
WARNING: Do not add or drain oil while the compressor is operating. The
compressor must be off, and power disconnected, before servicing can
be performed. For the safety of the maintenance personnel, lock-out and
tag out procedures must be strictly followed.
The capacity of the lube oil system is approximately 24 gallons (91 liters) for this model.
The oil level viewed on the sight gauge will vary when the compressor is operating. Fill
the sump to the upper limit of the gauge then run the compressor. Stop the unit and add
oil as necessary to maintain the oil level near the center of the sight gauge while the
compressor is running.
6.15.2 Cat DEO (Diesel Engine Oil)
Due to significant variations in the quality and in the performance of commercially
available oils, Caterpillar makes the following recommendations:
•
Cat DEO-ULS (Diesel Engine Oil Ultra Low Sulfur) (SAE 5W-40)
•
Cat DEO-ULS (Diesel Engine Oil Ultra Low Sulfur) (SAE 10W-30)
•
Cat DEO-ULS (Diesel Engine Oil Ultra Low Sulfur) (SAE 15W-40)
