That form is available through caterpillar legendary literature but you have to order it. There is no form that covers the 22 engine that I know of.

Hi Wally (or anyone : ),
what would be the engine most similar to that in the Twenty-Two. I saw R2 mentioned but my understanding is that the R2 engine is just the D2 engine with some different parts. I figure if there is a service manual (meaning disassembly and reassembly, not general maintenance) for a "mostly" similar engine, that might do the trick. Perhaps it's the case that the Twenty-Two engine is a unique design?
