Part of the Kubota Parts Manuals.
This is the Kubota LA302 loader parts catalog, a 42 page illustrated PDF that lays out the loader in its exact factory assemblies. It covers the main frame, brace, boom, the control valve in both 3 position and 4 position types, the control lever, the boom and bucket cylinders, and the full hydraulic hose, tube, and block circuits.
Each section pairs an exploded diagram with a numbered parts list carrying Kubota part numbers, quantities, serial number ranges, and component weights. You can match a reference number on the drawing to the right part, and the serial columns tell you which version fits your loader.
Use it to identify control valve and detent parts, hydraulic hoses and couplers, cylinder seal kits, and frame hardware for repairs like a loader that will not lower, a leaking coupler, or a boom rebuild. Operator manual accessories are listed at the back.
