1.3 Post-lubrication of the Cylinders
Post-lubrication starts automatically during the slow-down of the engine.
1) Close the shut-off valve on the control air supply (supply of air from the board
system).
Note: Make sure that the lubricating oil pump is set to off before you bleed the
air spring system.
Where possible, keep the cooling water warm to prevent too much of a decrease of
the engine temperature. The cooling water pump thus, continues to operate unless it
is necessary to stop the pump for maintenance.
2) At frequent intervals and with the indicator valves open, use the turning gear to
turn the engine as necessary (you can do this daily in damp climates). Do this
procedure while the lubricating oil pump and servo oil service pump operate and
set to on the cylinder lubrication at the same time. After this procedure is
completed, make sure that the piston stops in a different position each time.
3) Repair all the defects found in service (leaks, etc).
