The label set includes pattern EP, key switch, brand, servicing assembly, grease usage, hydraulic oil usage, turning lock, slope, transport, battery, swing area, radiator, engine hood, engine room, muffler, boom, fuel, hook, fuse, grease, variable, specification, lift, oil & water, air cleaner, reserve tank, anti-freezing, pinch and folding labels. Each is listed with its genuine Yanmar part number and quantity per machine. Safety labels and ROPS/seat belt decals are clearly separated so you can order the exact replacement without guesswork.

This is the most detailed hydraulic control documentation in the catalog and is indispensable when resealing or replacing valve sections.

Why This Yanmar B08-3 Parts Catalog Matters

When you are repairing or rebuilding a Yanmar B08-3 crawler backhoe, the difference between the right part and a near-match is often a few millimetres, a different thread pitch or a revised seal design. This parts catalog gives you the genuine Yanmar part numbers for every assembly on the machine, from the smallest cotter pin and O-ring to the complete control valve, travel motor and boom cylinder. The exploded illustrations show exactly how each component fits together, and the interchangeability marks, change marks and level indicators tell you which parts supersede earlier designs. Whether you are servicing a US-spec B08-3 or an Australian-spec machine, the catalog covers both and lists the engine as the 2TNE68-EBVA with serial range 20007 and up. The label and safety decal section lets you restore the machine to its original specification, and the wiring diagram gives you the colour codes, terminal numbers and wire gauges needed to diagnose electrical faults. The hydraulic piping sections, with their full hose codes and routing, are particularly valuable when replacing damaged hoses or rebuilding a machine that has been partially disassembled.
