OIL CHECK

1.Visually inspect oil plug hole to verify that oil cavity is full enoughtocoversealspring.Checkevery300hours,change hydraulic oil every 6 months (1,000 hours) or as needed.

Make sure the clearance between the impeller and the friction disk is approximately .012 - .020 inches (.304 -

.508 mm.)

If impeller is defective or badly worn, replace impeller imme- diately.

REMOVE FILL PLUG, AND VISUALLY INSPECT THAT

OIL CAVITY IS FULL ENOUGH TO COVER SEAL SPRING.

FILL TO 75-80% CAPACITY SEE TABLE 1 FOR FILLING CAPACITY.

FILL WITH 10 WEIGHT NON- DETERGENT HYDRAULIC OIL. USE SHELL TURBO 32 OR EQUIVALENT.

CHECK HYDRAULIC OIL EVERY 300 HOURS. CHANGE EVERY 6 MONTHS OR AS NEEDED.
