What This Parts Catalog Does For You

This is not a repair manual—it is a complete illustrated parts reference that tells you exactly which component goes where on your WA380-3. Every assembly is drawn in exploded view with numbered callouts matched to a table of part numbers, descriptions, quantities, and serial-number applicability. When you need to replace a worn bushing, a cracked housing, a leaking seal, or a broken bracket, you can see precisely how the assembly comes apart and goes back together, and you can order the exact part number without guesswork.

The catalog covers the entire machine: engine mounting and accessories, transmission and torque converter, drivelines, front and rear axles, brakes, steering, hydraulics, loader control, cab and operator station, electrical systems, air conditioning and heater, and all the sheet metal and structural components. With 447 pages of diagrams and parts data, it is the most thorough visual reference available for the WA380-3 from serial number 53001-UP.

Why This Matters

Ordering the wrong part costs time and money. A parts catalog eliminates the guesswork by showing you the exact configuration for your machine’s serial number range. The WA380-3 had running changes across its production run, and this catalog notes which parts apply to which serial number ranges (53001-UP, 54001-, 54101-, and others). That level of detail prevents ordering a part that fits a different build.

For workshops, fleet managers, and owner-operators, having the illustrated parts catalog on hand speeds up every repair and maintenance job. Instead of relying on memory or vague descriptions, you can point to the exact item on the diagram and pull the correct part number in seconds.
