HYDRAULIC OIL IN GEAR BOX

HYDRAULIC OIL IN GEAR BOX

(OP)
FOUND "TECHNODRIVE" TRIPLE DRIVE GEAR BOX (DRIVES 3 HYD PUMPS ON A CRANE)CONTAMINATED WITH HYD OIL. SUSPECT LEAK FROM ONE OR MORE PUMPS INTO GEAR BOX.

LOOKING FOR WAY TO 1)CONFIRM  HYD OIL LEAK FROM PUMP INTO GB 2)DETERMINE WHICH OF THE 3 PUMPS AT FAULT.

LOGISTICS CONTRAINT- DOWNTIME OF CRANE < 1 DAY. BUYING 3 PUMPS (DIFF MODELS) SOLVE THIS BUT EXPENSIVE AND WASTEFUL.

APPRECIATE ANYONE WHO CUD SHARE THIER EXPERIENCE.

THANK YOU ALL.

RE: HYDRAULIC OIL IN GEAR BOX

You may be able to tell by looking at the case drain level in each pump. If you can’t see a level difference, apply about 25 lbs air pressure to case drain. This should cause the seal to leak oil and if low air.
