General

NOTE

To identify the consumable materials refer to the PCI.

If installed remove storage parts from the oil scavenge pump.

Do not allow oil to become aerated.

Make sure that the drive oil pump turn free by hand.

Pump rotation must be anticlockwise (view the drive end).

Monitor the pump for unusual noises during the test.

For standard torque data and procedures, refer to SPM TASK 70-41-02-400-501 and SPM TASK 70-42-00-400-501.

WARNING

DO NOT GET ENGINE OIL ON YOUR SKIN, IN YOUR MOUTH OR IN YOUR EYES. ENGINE OIL IS POISONOUS AND CAN GO THROUGH YOUR SKIN AND IN TO YOUR BODY. FLUSH ENGINE OIL FROM YOUR EYES, MOUTH OR SKIN WITH WATER. GET MEDICAL AID IF YOU GET ENGINE OIL IN YOUR EYES OR MOUTH.

WARNING

DO NOT TOUCH THE HOT PARTS WITHOUT PROTECTIVE GLOVES. HOT PARTS CAN CAUSE REDDENING AND BLISTERING OF THE SKIN IF THE HANDS ARE NOT PROTECTED. IMMERSE THE CONTACTED AREA IN COLD WATER FOR 10 MINUTES IF THE SKIN IS BURNED. GET MEDICAL AID IF PAIN OR BLISTERING PERSISTS.

4. SUBTASK 79-22-41-790-052 Do the Running-in on the Oil Scavenge Pump

   1. Set up the test bench. Refer to Figure.

   2. Adjust the heater to maintain the oil supply at a temperature of 230~F (110 deg C).

   3. Operate the oil scavenge pump, adjust the speed to 2860 rpm, the discharge pressure to 25 psi (172 KPa) and the vacuum inside sumps to 0 in.Hg.

   4. Run-in the pump for 30 minutes.

   5. Monitor the oil level in the sumps.

5. SUBTASK 79-22-41-790-053 Do the Altitude Simulation Test on the Oil Scavenge Pump

   1. Operate the Vacuum pump and adjust the vacuum in the six sumps and the oil flow to the first value given in Figure.

   2. Adjust the flow in order to keep the oil level in the sumps constant.

   3. Wait for five minutes and check again the oil level in the sumps.

   4. The oil level in the sumps must remain constant.

   5. Repeat steps Step, Step, Step and Step for all the values requested in Figure.

   6. Read and record on the scavenge pump data sheet all the required values. Refer to Figure.

6. SUBTASK 79-22-41-790-054 Do the Sub-Idle Simulation Test on the Oil Scavenge Pump

   NOTE

   Do not change the oil pressure discharge setting.

   1. Operate the vacuum pump and adjust the vacuum in the six sumps to 0 in.Hg.

      1. Set the pump speed to 400 rpm. Refer to Figure.

      2. Adjust the oil flow to the value given in Figure.

   2. Adjust the flow in order to keep the oil level in the sumps constant.

   3. Wait for five minutes and check again the oil level in the sumps.

   4. The oil level in the sumps must remain constant.

   5. Read and record on the scavenge pump data sheet all the required values. Refer to Figure.
