Part of the Yanmar Parts Manuals.
All 37 pages of this Yanmar 3TNE88-(E)B1(B37-2B) Parts Catalog (OEM #Y00B5902) focus on one thing: pinning down the exact part number for every component in your vertical multi-cylinder industrial diesel engine. Open to any of the 14 system chapters (cylinder block, crankshaft and piston, fuel injection pump, governor, cooling water system) and you get a full exploded view alongside a numbered parts list with factory part numbers and cross-references. Inside: engine, fuel, and electrical parts sections organized so you can identify the right component before you ever pick up the phone to order. Your V-belt crosses to an A-38; the oil filter lands at size 80X80L, the kind of factory part identification that keeps you from ordering the wrong piece twice. Wrong part, wrong order, wasted week. Bookmarked by system; search any part name in seconds and get back to the counter with the right number.
