Book or DVD on Learning Diesel Engines

I have been working on gas engines most of my life and have succesfully rebuilt a few.

As I roll up on retirement, I want to be able to diagnose and repair diesel problems I am likely to run into. I have both the D905 and D1105 engines.

Could anyone suggest good training materials for the diesel engines like these? A bonus would information about Kubota's hydro as well.

Thanks in advance.
