For an engine that that was shut down after a long period or an overhaul, do the
special procedures in paragraph 2.
Note: If the engine was shut down only for some days, you must do the
procedures given in 0110−1 Prepare for Engine Start after a Short
Shutdown Period.
2. Special Procedures
1) Do a check of the engine control as given in 4003−1, paragraph 4.
2) If bearings or parts of the running gear were replaced or removed (for checks),
do a check of the the lubricating oil supply at the usual oil pressure (see 0250−1
Operating Data Sheet).
3) Do a visual check through the open running gear doors to see if there is sufficient
oil flow from all bearing locations.
During the operation period, it is recommended that you monitor the parts for unusual
heat. You monitor the parts as follows:
4) Start and stop the engine for short intervals (see 0210−1 Temperature, paragraph
9).
5) Compare the temperatures of the newest parts with those that were installed
before.
6) Start and stop the engine for longer intervals.
7) Compare the temperature again as given in steps 4) to 6).
Note: For data about running-in new pistons, piston rings and cylinder liners,
see 0410−1 Running-in New Cylinder Liners and Piston Rings.
8) Make sure that the scavenge air and exhaust gas can flow freely.
9) If the cooling water for the scavenge air cooler was drained, fill and bleed the
system.
