- Basics of how a diesel works - with cutaway parts, diagrams, whatver, so we can SEE each piece and system -- visual vs verbal instruction.
- What makes a marine diesel different than any other diesel (what things are unique to them?)
- What are the top 10 ways to do hurt my diesel and how can I avoid each? Have physical examples of each around (or, photos)
- How can I tell if someone else has done any of these things?
- A list of "beginner" skills and how to do them (oil change, filter changes (all of them), H.E. Zincs, check/adjust alt. belt tension, bleed an engine), as well as intermediate ones (check/clean/change out heat exchanger, check function of glow plugs, check injector pump, check out and clean siphon breaks (easy, but a pain), etc.
- Who in my area is the "go to" person for my type of engine (some recs for good mechs)
- Have or develop a scheduled maintenance program for the engine

I've actually gotten to learn these things over the past year, some by one on one with a good mech, some by reading, some by friends --- but there are some great classes put on locally, and the things above would be what I would want to know!

For what it is worth.

How to get a standard laptop to talk to my diesel engines computer so I can see for myself the status of the engine without having to resort to paying someone $90 per hour to tell me this.

First, I would like to learn it wouldn't cost $1,000 to take.
Secondly, how to tear one down as far as posible, without getting into specialized tools or pulling the engine out for a complete overhaul, then put it back together in working condition. There always seem to be an educational gap between a basic how to diesel course (oil change, water pump impeller replcement etc.) and a complete full diesel mechanic class.
Just my two cents.

That is because there is a big gap. That is one of the beauties of a Diesel. They will run and run until they don't and then you have to do major work. Unlike a petrol engine where you have to tinker with tunning every few hrs. A diesel really us about filters and fuel.
Windsaloft, you will find most of that info in the Study Hall. But it is nice to be steped through it all with a class if you can find one at a reasonable cost.

Generally it's a systems based course. Starting system, electrical/charging system, fuel delivery system, fuel metering system, exhaust system, cooling system, drive system/transmission/propeller shaft and prop systems.

Part I - How the systems work
Part II - How to troubleshoot them
Part III - How to repair them

The number of people who will actually tear apart the engine - i.e. remove the head, pistons, cranks etc. in the life of cruising is probably 1 in 1,000 or more. When the donk is dead people generally limp home and repower.

Systems training however would be very valuable.

Sounds good Dan.
I use these two vids to help show the workings to my students. They are petrol, but it is still a damn good example of all the workings.
This one is all the parts of the engine.

This one is the operation of the engine

Yeah I agree, good vid's, but ummm, is the firing order incorrect? (I know I'm being pedantic ) btw: I think I can rip those vids if you want 'em as a file.

As a young boy, my grandfather gave me a large illustration book on motor vehicles (it was a reader's digest one). It had everything in it about engines (incl diesel) electrics (parts of alternator, starter etc), even had data on turbo's & gearbox overdrive clutches. Everything was piece by piece & explained what it did etc. That book help me past the engineering part of the examine for my tickets.

Btw: anyone stand next to Gardner 8L3B, those things are massive!

Yesterday I was having some work done on my car.
While I was talking to the Mechanic, a woman came in and asked for a seven-hundred-ten.... We looked at each other, and the mechanic asked, 'What is a seven-hundred-ten?'
She replied, 'You know, the little piece in the middle of the engine. I lost it and need a new one. It had always been there.'
He gave the woman a piece of paper and a pen and asked her to draw what the piece looked like.
She drew a squiggly circle and in the middle of it wrote 710.
He then took her over to another car which had the hood up and asked, 'Is there a 710 on this car ?' She pointed and said, 'Of course, its right there.'

I top off my transmission fluid through the 710. Is that bad?

I don't think that most people need a theory course. Just a how to look after it all course.

Could even go so far as valve adjustment, cleaning a heat exchanger, cleaning and replacing an exhaust elbow, servicing the water pumps, checking the oil and coolant and of course bleeding the fuel system.

How to check the belts and adjust the belt tension. What good and worn out belts look like. Signs of a slipping belt.

Gotchas in the fuel system, etc. Where to start looking when the engine wont start, smokes, runs for a while and shuts down, etc.

How to remove and properly handle fuel injectors.

Might even want to address the 710 problem.

A friend of mine was working at a small service station some years back. She had a customer that wanted to top up the engine with oil. She left him to it and after sometime she realized he had not come back with the filler nor to pay for it. She looked outside and the gentleman was carefully trying to pour the oil in where the dipstick went.

I do not like engines and they do not like me. For some reason, they stop working. That is why I have a sail boat. Right now I think I have a cooling system leak. I know I have to buy a pressure guage and affix it to the closed water cooling system to make sure. This is not fum.
