(2) Make sure that there is no blockage or kink in the AGE10600D CHECK-MOTOR GROUND,RAT return line.
(3) Install the AGE10600D CHECK-MOTOR GROUND,RAT on the RAT with RAT Safety Interface Kit (RSIK) as follows:

NOTE: If the AGE10600D CHECK-MOTOR GROUND,RAT is not available, you can also use these check motors:

Tronair AGE10600A
Tronair AGE10600B
Tronair AGE10600C
Testfuchs RATMK
Hycom HRT01
BH4016A2.

NOTE: If the RSIK1 RAT INTERFACE MODULE is not available, you can also use this safety interface:

BH4016A3.

NOTE: The function of the RSIK1 RAT INTERFACE MODULE is to prevent the RAT gearbox from damage from the ground test motor (high pressure leakage).

(a) Remove the bolts (3), the washers (2) and the cover plate (1).

NOTE: If the adapter pinion (12) is installed, go to step (h).

(b) Push in the adapter pinion (10) of the AGE10600D CHECK-MOTOR GROUND,RAT (7).
(c) Use the PLIERS - NOSE, SOFT, LONG and the DRIFT - PUNCH to remove the locking spring (11) from the relief groove.

WARNING: KEEP ALL PERSONS AWAY FROM THE AREA WHEN YOU PRESSURIZE THE BLUE HYDRAULIC SYSTEM. WHEN YOU PRESSURIZE THE BLUE HYDRAULIC SYSTEM, THE RAT CAN TURN AT MORE THAN 5000 RPM.

WARNING: OBEY THE HYDRAULIC SAFETY PROCEDURES.

WARNING: ALWAYS WEAR RUBBER GLOVES, GOGGLES AND PROTECTIVE CLOTHES WHEN YOU DO THIS TASK.

(1) Obey the hydraulic safety procedure (Ref. AMM TASK 29-00-00-910-002).

NOTE: Always monitor the transparent discharge hose and the fluid container. When the hydraulic fluid flows from the RSIK through the discharge hose into the container, stop the test immediately to prevent damage to the RAT gearbox. If the hydraulic fluid is there, the ground test motor is damaged. The damage causes leakage in the direction of the RSIK. The hydraulic fluid from the motor can cause damage to the RAT gearbox. At the beginning of the leakage, the RSIK can move the fluid. If the leakage occurs, replace the ground test motor and examine the RAT gearbox for the damage that the hydraulic fluid caused.

(2) Make sure that the Blue hydraulic system is serviceable.

NOTE: The operation of the Blue electric pump is necessary to pre-charge the Blue hydraulic system accumulator for the spin-up and governing test.

(3) You must look at the temperature gage of the AE89415Z FLOW CONTROL TEST - RAT or the HFK02 TEST KIT, FLOW CONTROL - RAT or the 13-6600-3600 TEST - UNIT, RAT or the PGRAT1 TEST - EQUIPMENT, RAT or the BH4016A RAT TEST EQUIPMENT during the test. The test values can be out of tolerance if the temperature increases to more than 60 deg.C (140.00 deg.F). If so, you must stop the test, let the temperature decrease and do the test again.
(4) Do the test that follows:

L. Inspection of the RAT after the Functional Test
(1) Inspection of the Indicator
(a) Examine the RAT and make sure that the differential pressure indicator is in the "in" position.
1 If the differential pressure indicator is popped out, replace the filter (Ref. AMM TASK 29-22-51-000-013) and (Ref. AMM TASK 29-22-51-400-013).

(2) Examine the RAT pump/gearbox splitline, the drain hole and the aft drain slot on the bottom of the RAT gearbox housing assembly for external leakage. Make sure that the external leakage is not more than:

60 drops an hour when the RAT is in operation,
2 drops an hour when the RAT is not in operation.

NOTE: The given values are only for the RAT pump/gearbox splitline, the drain hole and the aft drain slot and not for the hydraulic connections. If you are not sure of the source of the leaks, it is necessary to:

Pressurize the Blue hydraulic system with 3000 psi
Examine the hydraulic connections and the related components.

(3) Inspection of the RAT Gearbox
(a) Do an inspection of the rear bearing in the RAT gearbox interface area:
1 If the bearing is damaged, replace the RAT (Ref. AMM TASK 29-22-51-000-010) and (Ref. AMM TASK 29-22-51-400-010).
(b) Do a leakage inspection of the RAT.
(c) Examine the RAT oil level:
1 If the fluid level is high and the interface is wet, replace the RAT (Ref. AMM TASK 29-22-51-000-010) and (Ref. AMM TASK 29-22-51-400-010).
2 If the fluid level is low and the interface is dry, add oil (Ref. AMM TASK 12-13-29-600-001).
3 If the fluid level is low and the interface is wet, replace the RAT (Ref. AMM TASK 29-22-51-000-010) and (Ref. AMM TASK 29-22-51-400-010).
(4) Install the cover plate (1), the washers (2) and the bolts (3).
