set is directional. It is not marked and must be installed correctly or it will leak. Look carefully at
the inside diameter of the seal, you will see three components. The middle black ring that is split
is a bearing. Above and below it are the brownish Turcite® seals, these are made with a step, and
the step faces the oil. Conrm this by looking into the seal from both directions, from one side
you will not see the steps, and from the other you will; this is the side that faces the oil.)
Refer to page 5 for parts reference.
Before starting any kind of maintenance
or repair, disconnect the compressed air
supply and open a downstream valve to
relieve the grease pressure.
