Part of the Yanmar Parts Manuals.
Order one wrong seal for a machine this old and you pay for it twice, once at the parts counter and again while the backhoe sits torn down waiting on the right piece. Yanmar's own publication number, 000Y00S3231, is printed on this catalog, which covers the B27-2 crawler backhoe from serial prefix 00501-43170 with the 3TNC88L - RB1 diesel engine.
Across 148 pages, exploded figures show each assembly the way it comes apart in your hands, from the air cleaner and muffler to the radiator and mount, engine mounts, accelerator linkage, and fuel tank. The picturesque index lets you find a component by looking at a drawing of it, then read off the exact Yanmar part number to give your dealer.
It is a PDF you download once and keep for this machine. No subscription, no lookup fees, just the factory's own part numbers.
