TASK 29-11-51-400-011-A
Installation of the Solenoid-Valve of Engine Pump

WARNING: OBEY THE HYDRAULIC SAFETY PROCEDURES.

WARNING: BE CAREFUL WHEN YOU DO WORK ON THE ENGINE PARTS AFTER THE ENGINE SHUTDOWN. USE APPLICABLE THERMAL GLOVES. THE ENGINE PARTS CAN STAY HOT FOR ONE HOUR AFTER SHUTDOWN AND CAN BURN YOU.

WARNING: DO NOT GET HYDRAULIC FLUID ON YOUR SKIN, IN YOUR EYES OR IN YOUR MOUTH. HYDRAULIC FLUID IS POISONOUS AND CAN GO THROUGH YOUR SKIN AND INTO YOUR BODY. FLUSH HYDRAULIC FLUID FROM YOUR EYES, MOUTH OR SKIN WITH WATER. GET MEDICAL AID IF YOU GET HYDRAULIC FLUID IN YOUR EYES OR MOUTH.

CAUTION: DO NOT LET HYDRAULIC FLUID FALL ON THE ENGINE. UNWANTED HYDRAULIC FLUID MUST BE REMOVED IMMEDIATELY WITH A CLEAN LINT FREE CLOTH. THE FLUID CAN CAUSE DAMAGE TO THE SURFACE PROTECTION AND TO SOME PARTS.

4. Procedure
Subtask 29-11-51-420-058-A ** ON A/C NOT FOR ALL

A. Installation of the Solenoid-Valve of Engine Pump P/N 887673 or 3031863-001
(1) Remove the shipping cover from the new solenoid valve (3).
(2) Make sure that the packings and the backup rings are correctly installed in the solenoid valve grooves.
(3) Lightly lubricate the packings and the backup rings of the solenoid valve (3) with Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) .
