Head Specs for Yanmar 2500

[Adron]

I (rather my mechanic) is in the process of replacing the head gasket and valve guides on my YM2500. I need the head specs (torque, valve length etc.), and have no idea where to find them.

Any help would be appreciated.
Thanks

Any Yanmar authorized parts dealer should be able to get you the service manual for the comparable US model, (same engine).

Call your local John Deere dealer and ask for the specs on a JD 850.
