EMERGENCY PROPULSION ENGINE SHUTDOWN (continued)
2.
After the engine stops, push the emergency engine control (28) all the way in.
3.
The emergency engine shutdown can only be reset from the engine room. The reset procedure is described in
TM 5-2815-231-14.
PROPULSION ENGINE FAILURE
One Engine Failure
In the event that one propulsion engine fails, proceed to safe moorage under the power of one engine as follows:
1.
Shut down the malfunctioning engine.
2.
Steer the vessel to compensate for the loss of the engine.
3.
If the vessel must be operated for more than 8 hours with an inoperative engine, follow the Transmission Backdriving
instructions in this work package.
Two Engine Failure
! CAUTION
Secure towing lines only to mooring or towing bitts. Never secure towing lines to
lifelines, handrails, or other deck hardware not intended for mooring or towing pur-
poses. Failure to comply may result in damage to the vessel.
In the event that both propulsion engines fail, the LCM-8 Mod 2 will have to be towed. Towing arrangements shall be at the
discretion of the coxswain. It may be necessary to anchor to prevent the vessel from drifting while awaiting a tow. Anchoring
procedures are contained in WP 0023 00.
Transmission Backdriving
The marine transmission can be backdriven (propeller windmilling with the engine secured) provided that the vessel speed
during the backdriving procedure does not exceed the normal propulsion speed of the vessel. To backdrive the marine
transmission:
! CAUTION
The marine transmission must be lubricated at least every 8 hours during backdriving.
Failure to comply will result in serious internal damage to the marine transmission.
1.
Start the engine and operate the marine transmission in neutral for a minimum of 5 minutes to lubricate the internal
transmission components. Do this once every 8 hours when the transmission is being backdriven.
2.
Maintain the marine transmission oil level at the FULL mark on the dipstick.
3.
If the propulsion engine is entirely inoperative and cannot be lubricated as described in step 1, perform the following
lubrication procedure:
a.
Plug the dipstick tube and fill the transmission completely full of oil.
b.
Before backdriving, drain the oil down to the full level on the dipstick.
