Removing boat engines requires you to need skills since a rigger more than a technician. You may contain to use any cutting torch if the vessel's deck planking is anchored by pieces of angle iron welded to some steel deck. You will maintain to disconnect the transmission from the propeller shaft to avoid a bent shaft or any damaged stuffing box or stern gland. After that, the method is little more than turning and removing bolts and trying to stay from of the way regarding an engine, perhaps swinging out of the motion about the vessel if the engine removal is never completed in dry dock.
Difficulty: Challenging
Things You'll Need
Cutting torch Large pipe or adjustable wrenches sized to the perform at hand Tools with disconnecting air, water and fuel supports from the engine Tools with disconnecting electrical service from the engine Dockside crane Two-way radios Safety equipment including: Safety shoes Safety glasses Leather gloves Tough hat Type III PFDs with deck workers 1/2 inch polypropylene series with 4 tag lines, 10 feet each with period Hand-held radios
1 Change the oil and oil filters for the engine. Remove the fuel filter cartridges, drain the fuel and replace the fuel filter cartridges. Disconnect all fuel lines, water lines and electrical services from the engine. Disconnect the air inlet hoses from the turbines. Remove the connector pins from the propeller shaft plus distinguish the shaft from the transmission. Loosen the mounting bolts holding the engine to the motor supports. Loosen the transmission mounting bolts and the bolts. If there are multiple bolts inside each transmission also engine support, remove all still particular bolt out of each engine mount and each transmission mount.
3 Make a hole from deck huge sufficient to remove engine by unbolting the engine entry hatch deal with above the engine room. When the includes are unbolted, rig a 4-part sling to the hatch cover using the pop-up pad eyes with the hatch cover. Have the dockside crane lift the hatch deal with to the wharf to expose the engine.
4 Rig the engine with a 4- or 6-part sling using the pad visions on the engine plus transmission. Have the crane bring the slings taut, but not taking any strain. Remove the bolts securing the transmission, out of the back about the transmission to the the front about the transmission, one bolt with a time from each side. Remove the bolts securing the engine away from the back of the engine to the front, single at any spare time on each and every side until only the two forward-most bolts are holding the engine.
5 Tell the crane operator to slack the rig slightly, to relieve the strain on the two forward engine bolts plus lessen the possibility about an accident ensuing from some swinging engine. Remove the 2 ahead bolts and include the crane operator take the right taut. Tie up label lines to the engine, never to the slings. Stand away two fore and aft from the engine and tell the crane operator to have a strain. Control the swing about the engine with the tag lines; whilst the engine remains stable, tell the crane operator to hoist out. Maintain control of the swing about the engine in the tag lines until the engine is clear the hatch.
Tips & Warnings
Be sure that the crane operator yous provided by way of a working radio on the same frequency as the individual in charge, understands the standard hand signals for crane operations plus recognizes the planned operation completely previous to beginning the function. This is one extremely hazardous evolution and safety is the primary concern.
Wear the required safety equipment appropriate to the task in hand, in accordance along with the vessel's Position Orders and common impression.
