! CAUTION
If there is any sign of water or oil being ejected at the cylinder test valves, or any indication of
obstruction while rotating the engine, refer to unit maintenance. Do not attempt to start the
engine until the problem has been corrected, or serious damage to the main engine could result.
d.
Check the starboard main engine test valves (figure 10, item 1) and air box blow down valves (figure 2, item 6) for
the presence of oil and/or water. If no oil or water are detected, continue with this procedure. If oil or water are
detected, notify the maintenance supervisor.
e.
Shut all the test valves (figure 10, item 1).
23. Ensure that the starboard main engine overspeed trip lever (figure 12) is in the RUNNING (latched) position.
24. Push IN the governor's alarm switch plunger (figure 11, item 1).
25. Check that the governor oil level is at the mid-point in the sight glass (figure 11, item 2). If the oil level is low, add oil
through the fill cap (figure 11, item 3). Refer to TM 55-1925-208-24 or the maintenance supervisor for the oil specifi-
cation.

train.
