Need help: Volvo-Penta MD7A Maintenance for Dummies

Hello all...

Recently picked up a 78' Newport 30 with an MD7A. It's the fist diesel I've dealt with and it would be helpful if I could be pointed to some how-to's on general maintenance. I.E. fuel filter replacement, bleeding the fuel system, etc.

I've found the shop manual and read the owners manual, but I find them a bit vague. I'm a visual person, so pictures would be greatly appreciated.

Thanks much.

Diesel's are pretty simple -- fuel, air and compression = combustion.

For a good general reference, it's hard to find a better one than Nigel Calder's Boatowner's Mechanical and Electrical Handbook. He's also got one specifically about diesel engines, but you get more bag for the buck with the first one.

"Marine Diesel Engines: Maintenance, Troubleshooting, and Repair" helped me a lot. As did copious amounts of patience and time ;-)

I believe the procedure for bleeding a MD7A depends on what style injector pump you have. You'll need to shake this out first.

I'm not happy unless I'm complaining about something.
I'm having a very good day!
