Yanmar Parts Manuals
A Yanmar engine parts book is keyed to the full engine code, suffix included, so the 4TNV88-QTB catalog for the Takeuchi TB145 is a different book from the 4TNV88-XMS. Copy the whole code off the nameplate before you buy. Marine catalogs like the 4JH2 series work the same way.
Machine catalogs make up the other half, from the ViO35-6A and ViO80-1A excavators to the C50R-3C carrier and the T210 track loader. The torque values and teardown steps are in Yanmar Repair Manuals.
