The manuals show up on fleabay on a fairly regular basis.

Is yours a 4valve?  If so I have the real shop manual.. I sent the 2 valve book just so you can see the book P/N.. Jojo.

I want to download one any one know where to get a digital copy 

My power manual.com... I have 5 or so downloads from them at less than $50.00.... I will be using one tomorrow. I have 3 John Deere 3cyl. diesel's to build. I got the download for $35.00.. Joey
