R  (d) Engage the wrench, part of TOOL SET, R/I - DRIVE SHAFTS (856A2718G02/P04) in the handcranking drive, throught the SAFETY PROTECTOR _ HANDCRANKING PAD (856A2796G01).
R  (4) Connect the hot air source and the FILTER ADAPTER (856A2659G01) to the ADAPTER, AIR - DRY OUT ENGINE SUMPS (856A3810G01).
 Subtask 72-00-00-160-053
 B. Dry-out of the engine
 WARNING : STAY CLEAR OF THE LUBRICATION UNIT BY 20 FEET BECAUSE HOT AIR_______ WILL BE BLOWN FROM THE TOOL SET-RELUBE ENG. SUMPS.
 (1) Turn on the hot air source.
 (2) Increase the air temperature slowly and continuously 150 deg.C (302 deg.F) to 163 deg.C (325 deg.F) .
 (3) Blowing:
 WARNING : WEAR HEAVY PROTECTIVE GLOVES TO AVOID INJURY WHEN MANUALLY_______ TURNING THE FAN ROTOR.
