Part of the Kubota Parts Manuals.
This is the factory Kubota LA402 Parts Catalog, a 42-page PDF you can download and print. It covers the LA402 front loader built in the 2002 to 2007 period, listing every serviceable part across the main frame, brace, boom, control valve, control lever, and hydraulic system. Each assembly pairs an exploded diagram with a numbered parts list, so you can match a component to its exact Kubota part number, quantity, and serial-number range before you order.
Use it to identify replacement hoses, tubes, loader cylinders, seal kits, pins, bushings, and fittings, or to rebuild the control valve and the boom and bucket cylinders. Serial breaks matter on this loader, since some references list separate part numbers for earlier and later machines and for the LA402 and LA402-1. Whether you are tracing a hydraulic fault or ordering wear parts, this catalog gives you the numbers you need.
