Part of the Yanmar Parts Manuals.
Swap a leaking hose on the underside of a YB10-2 and you will want the exact adaptor and O-ring numbers in hand before the machine goes back on its tracks. This parts catalog for the Yanmar YB10-2 excavator (publication Y00K2301) is where those numbers live: 97 pages of exploded diagrams keyed to Yanmar part numbers.
It covers machines in both serial ranges, M/#~00780 and M/#00781~, and works section by section through the whole machine: lower frame, crawler belt, idler and crawler adjuster, driving wheel, blade, lower hydraulic piping, turning driving gear, main frame, driving controls, radiator and engine mount, electric parts, main valve, hydraulic oil tank, boom and arm, and the tool list.
Ordering pins, bushes and seals by eye off a worn machine is how you end up with a part that almost fits. Match the diagram, read the number, order once.
