recommendation for yanmar shop manual

[jpendoley]

I have a new to me Yanmar4jh2-dye 87 hp. My last engine was a dirt simple perkins 4-108. This yanmar is much more complex, tighter in terms of component access and has a turbo. I do all my own maintenance and repair-the manufactures manuals seem very difficult to use and might as well be written in japanese. Can anyone recommend a really good shop manual for someone who wants to do all thier own maintenance and repair?
I need to learn this engine and need a good, explicit and well laid out parts and service manual.

The Yanmar service manual for this engine is pretty good. You should be able to find it with an internet search.

One of the most useful resources when working on a Yanmar is the spare parts catalogue as it shows how all the mixed up parts you have in a bucket fit together and more or less in what order.

I think much more useful than the manual.
