Towing Information
If the vessel cannot continue under its own power, it is recommended that the vessel be towed. If pressurized oil cannot be supplied to the marine gear shaft bearings while being towed, the propeller shaft must be secured so as to prevent the turning shaft (caused by the propeller windmilling through the water) from damaging the marine gear shaft bearings.
Turning of the propeller shaft without proper lubrication for long periods will damage the marine gear shaft bearings.
After the shaft has been secured, have the towing vessel travel at slow speed in order to minimize the windmilling force on the propeller. If, while the vessel is being towed and the marine gear is allowed to windmill for long periods, the engine must be started and the marine gear operated for five minutes every twelve hours to lubricate the shaft bearings.There are several ways of preventing shaft rotation; the correct method depends upon the turning force of the propeller, and the construction of the propeller shaft tunnel. Use the method best suited for the type of installation.* On small vessels, wrap a heavy rope around the propeller shaft. The number of wraps needed will depend upon the mass of the propeller and propeller shaft.* Secure the rope in the opposite direction of shaft rotation.* Remove one or more bolts from the companion flange coupling. Bolt a chain to the companion flange. Wrap the chain several times around the propeller shaft.* Secure the loose end of the chain at a right angle to the shaft and in opposite direction of shaft rotation.* For vessels equipped with a shaft brake, the shaft brake may be applied if there is sufficient air pressure available.Come-Home Method
MG514C Marine Gear Only
If the marine transmission oil pressure is absent and the clutch can NOT be engaged, use the come-home method if there is no other means to return to port. The engine must be warm. If necessary, start and allow engine to idle until it is warm.
Use the come-home method ONLY in an emergency situation. If the marine transmission lubricating oil pressure is absent, travel with extreme care and at minimum engine speed to avoid damaging transmission shaft bearings.
1. Stop the engine.
Always shut off the fuel supply and disconnect starting system before performing any repair procedures. Accidental engine rotation or starting can cause personal injury.
2. Mechanically engage the "ahead" clutch in the following procedure.a. Remove two access plugs from the manifold for the forward or reverse clutch cylinder.b. Use a 9S9082 Engine Turning Tool to turn the engine flywheel and crankshaft to make an alignment of the lock-up setscrews with the plug openings.c. Alternately tighten the hex socket setscrews until they are tight.d. Again use the 9S9082 Engine Turning Tool to turn the engine flywheel to make an alignment of the two remaining setscrews and tighten them.e. Install the two access plugs in the manifold. The drive and driven clutch plates are now mechanically clamped together for a solid drive through the clutch. The transmission is always in gear under this condition.3. Measure the marine gear oil level and maintain oil at approximately 127.0 mm (5 inches) above the FULL mark on the dipstick.
The starting motor will be turning marine gear, propeller shaft and propeller as well as the engine while cranking. Damage can result from excessive heat in the starting motor caused by overcranking. Allow starting motor to cool for two minutes after each 30 second cranking sequence.
4. Start the engine. After starting, travel with caution, at minimum speed.5. To stop the vessel, stop the engine. Remove the bolts engaging the clutch when the engine is stopped. Disassemble and inspect the clutch plates for warping and cracking. Damage can occur by having the clutch plates mechanically engaged. Under severe operating conditions, the marine gear should be disassembled and all bearings inspected closely.Engine Jacket Water Pump Failure
If the engine jacket water pump should fail, fresh water can be supplied to the engine jacket using the emergency water system.
Tee Connector (1), Shut Off Valve (2), Emergency Jacket Water Pump (3), Tee Connector (4) & Shut Off Valve (5).1. Stop the engine. If the water pump bearing has failed, the water pump does NOT need to be removed.2. Open valve (2) between the emergency pump and oil cooler connection. 3. Place the diverter valve handle in the EMERGENCY position.4. Start and prime the emergency jacket water pump (3). Allow air to escape from the emergency cooling system lines.5. Check coolant level in the expansion tank. Add coolant if required.6. Start the engine. Always start the engine according to the required Engine Starting procedure described in this manual. Engage marine gear and operate vessel at normal speed. If the engine jacket water coolant is lost (i.e. water line rupture or leak) and an insufficient supply of fresh water is available to replenish the system, raw water may be pumped through the engine.a. Stop the engine and make the necessary water pump and lines connections to pump raw water into the jacket water system and back to the source.b. Remove the temperature regulating thermostats from the regulator housing and install housing cover.c. Start and prime the emergency pump.d. Start the engine and allow to idle at low idle. Always start the engine according to the required Engine Starting procedure described in this manual. Engage the marine gear forward clutch. Operate the engine at the lowest speed for the existing weather conditions.e. Maintain engine temperatures as low as possible to minimize deposits in the engine and corrosion of components. Have the engine jacket water system completely disassembled, cleaned and inspected after reaching port. Replace all parts which are corroded or damaged.Engine Raw Water Pump Failure
The raw water pump circulates sea or fresh water through the engine jacket water heat exchanger. If the raw water pump should fail, follow the procedure below to continue engine operation.
