Oil Cooling Requirements (see Engineering Drawings for additional specs.)
Table 2. Oil Cooling Requirements
Customer supplied air to oil cooling is typical
Minimum oil temperature at start-up
-40°C (-40° F)
Oil temperature at steady operating
conditions
66°C to -85°C
(150°F to -185°F)
Maximum oil sump temperature 93°C (200°F)
Oil System
Oil Level
The customer supplied sump oil level should be checked daily or every ten
hours.
Oil and Filter Change Interval
With a new unit, change the oil and filter element within the first 50
hours of operation. Change oil and filter element after each 1000 hours
thereafter or more often if conditions warrant. The oil and filter should be
changed every six months if less than 1000 hours has accumulated since
the last oil change.
For a repaired unit, check the filter element after eight hours of operation.
If the filter is clean, install a new filter element and then change the oil
and filter element after 1000 hours of service. If the filter is dirty, change
the element and operate for another eight hours. Check the filter again.
Continue this cycle until the filter is clean and then change the oil and filter
after 1000 hours of service or more often if conditions warrant.
Torsional Coupling
1. Do not obstruct the flywheel housing vents preventing the free flow
of air for cooling the coupling. The ambient temperature of the air
around the coupling should be between -60°C. (22°F.) and 80°C.
(176°F.). Assure baffles are installed properly so hot air is ported
out of the housing.
2. Visually inspect the element after the first 100 hours of operation
and every 2000 hours thereafter, or every six months, whichever
comes first. Torsional vibration, misalignment, degradation by
contaminants (oil), heat, ultraviolet radiation, and excessive system
torque can cause cracks or other signs of distress to appear on the
surface of the rubber. The above described items affect the life of
the coupling element.
