Part of the Yanmar Parts Manuals.
The fuel injection pump is where a TNV rebuild goes sideways: order one wrong plunger or delivery valve and the engine sits on the stand for a week while parts go back and forth. This Yanmar parts catalog is built to stop that. It covers the 3TNV88-GGE, 3TNV88-DSA, DSA2 and DSA3, plus the 3TNV84T-GGE, 3TNV84T-KSA, 3TNV82A-GGE and 3TNV82A-DSA, with exploded diagrams and part numbers for every major group: cylinder block, cylinder head, crankshaft and piston, lubrication, cooling water, fuel injection, starting motor and generator, along with optional kits from air cleaner to radiator.
When you are alone with a stripped engine and nobody to ask which gasket set or bearing fits your exact variant, this is the reference. At 29 pages the PDF rides along on a phone or laptop, wherever the engine happens to be.
