Part of the Yanmar Parts Manuals.
Somewhere around the third parts order for a 3TNV88-XBV rebuild, the guesswork gets expensive: an oil seal that fits a different 3TNV88 variant, a bearing set one spec code off. This catalog ends that. It is Yanmar publication Y00B7200, the 34-page parts book for the 3TNV88-XBV, with exploded views and part numbers for every group on the engine.
The coverage runs from the cylinder block through the gear housing, cylinder head, camshaft and driving gear, crankshaft and pistons, fuel injection pump, injectors and fuel lines, the lube oil and cooling water systems, starting motor, generator, and the non-asbestos gasket set. Rebuild sizes are listed too, including 0.25 undersize main and thrust metals and 0.25 oversize pistons with rings.
Whatever this engine powers, the point is the same: match the diagram, read the number, and order the right part the first time.
