HYDRAULIC COMPONENTS (cont’d)
4.7. PAY OUT APPLICATIONS
A candidate for external oil circulation is an application that requires pay out of a load
for a period of more than 5 minutes. If you require assistance in determining the
amount of oil required for circulation, contact the factory.
The oil should be circulated through the Brake Housing via the circulation port marked
"P" and out through the vent port marked "Q" on the hydraulic schematic.
NOTE: Raised cast letters have been used to clearly identify these two ports on the
winch.
The hoses used for these two lines can be "push on" type low pressure hoses
THE PRESSURE IN THE BRAKE HOUSING DUE TO CIRCULATING OIL MUST NOT
EXCEED 10 PSI (0.7 ATM).
EXCESSIVE PRESSURES WILL DAMAGE THE OIL SEALS.
Once the hydraulic circuit has been completed, bleed all air from the brake housing
before running the drive.
For installations where the amount of heat absorbed by the oil is greater than the
cooling capacity of the reservoir and the other components, it is necessary to install a
heat exchanger. The temperature of oil at any point in the system must not be allowed
to exceed 180° F (82° C). It is recommended that the pump inlet temperature be limited
to 130° F (54° C). Definite operational advantages will be obtained by operating below
130° F (54° C).
In order to obtain smooth control during low speed pay out, it is recommended that the
hydraulic pump be operated at maximum speed.
