So I take it that this engine has never truned over for five years???
How many hrs on the engine???
Drain engine oil first off. DO NOT allow old oil to run back up around the engine. Drain it so as any water in the bottom of the sump can be got rid of.
DO NOT TRY STARTING THE ENGINE AT THIS POINT!!!!!
OK, presume the engine will initially be siezed. It won't be solid never to go again, but it could be stuck in place and stuck enough to stop you from turning it with ease. So you will need to get a long bar onto the front crank and work it backwards and forwards till the engine free's and then turn it over two compleate revs to ensure all is OK and no valves are stuck in the open position. DON'T try turning it over with the starter. You could break or bend something.
DO NOT try and start on the old fuel. Drain it all compleatly and clean and visually inpsect the insides of the tank. They could be full of rust/bug/holes. I would suggest for the initial run up, you use a small container that can place the fuel pickup hose in and use fresh fuel.
Fit new fuel filters. And on the mechanical lift
pump, remove the cover and ensure the screen
inside is clean. Once all is clean, use the lift pump and crack the bleed nut on the fuel filter
and pump fuel through till all air os gone. Then crack the bleed nut on the injector pump and pump till air is gone. The next step of getting the air from the injectors is done by turning the engine over. The lift pump will not push fuel through to this point. Pull the stop lever to the stop position so the engine will not start. Crack the nut on the fuel rail to the injector and turn the engine over till the air is gone, then tighten it. Work along the row of injectors.
DON'T START THE ENGINE YET. With the stop lever out, now turn the engine over till the oil pressure comes up. Then push the stop lever back in and turn it over, it should hopefully fire up.
is something you will have to give a good inspection
of. Not much to say there. Salt water cooling
pump will need a new impellor. Ensure the shaft and key inside has not corroded away. Fresh water pump should be OK. Lets hope they have left anticorrosive fluid in the water. This will need flushing
anyway and new water and new inhibitors added as the old stuff will not be active anymore. That can be done after you get it fired up. Give it a good flush through.
Change belts. Alternator should be OK after it has run awhile. Starter should be OK. But both could have frozen bearings, so check they turn over OK. The Alternator will be ball bearing and so listen for noise
, the starter is possibly bronze, so you may want to strip the starter once the intitial engine work has been done, and ensure it is all OK. If either either niether work, you need to check the brushes
and comutator is clean and not corroded.
