This is the full Kubota U50-5 excavator Illustrated Parts List, published under document number 97899-12980 with a June 2020 date. It is the trilingual parts catalogue that Kubota issues for the U50-5 Bagger / Pelleteuse / Excavator, giving every assembly an exploded view plus a numbered table of part references, part names and designations across three languages. If you own, service or rebuild a U50-5, this is the document you use to look up the exact part number before ordering, and to see how a component is built before you take it apart.

For a technician, the value here is that every assembly is broken down to the level Kubota sells it at – so you can see not just the whole pump or the whole swivel motor, but the individual bearings, seals, O-rings, plates, springs, plungers and poppets that make it up. Interchangeability notes, serial-number break points and quantity-per-assembly are printed alongside the parts, and a Numerical Index at the back lets you jump from a part number straight to the page that lists it.

How the Parts List is Organised

The manual uses a layered layout that is quick to navigate once you know it. SECTION CONTENTS on the opening pages shows the whole machine with callouts to the major systems – electrical system, operator’s platform, engine, external/upholstery, fuel system, swivel frame, track frame, pump/motor system, oil piping, front attachments, control valve, control lever and cylinder. From there, each system has its own Fig. No. that groups the sub-assemblies (for example the engine group contains 500000 crankcase, 501000 oil pan, 502000 cylinder head, 511000 piston and crankshaft, and so on). Each sub-assembly has a diagram with numbered callouts, and the corresponding table lists Ref. No., Part No., Part Name, Designation, Quantity and Remarks.

The document also explains the serial-number and interchangeability conventions Kubota uses – how a group of serial numbers is written, how month and year of manufacture are encoded in the engine serial number, and how the I.C. column tells you whether a newer part supersedes an older one, whether they are interchangeable in both directions, or not at all. That matters when you are buying a replacement for a machine that has been through a mid-production design change.

Who This Parts List Is For

This is aimed at the person who needs to order the right part the first time. Whether you are a workshop rebuilding a U50-5 swing motor, a fleet mechanic replacing a track roller or an undercarriage component, an owner looking up a hydraulic hose or control valve section after a failure, or someone restoring a machine and needing labels and trim items, this parts catalogue gives you the Kubota reference for it. Because the parts list is trilingual, it also suits operators and workshops working in English, French or German-speaking markets.

Why a Proper Parts List Beats Guesswork

Third-party parts cross-references and generic online catalogues frequently get the last digit of a Kubota part number wrong, or miss serial-range differences that mean a part that fits one U50-5 does not fit another. This parts list is the document Kubota itself publishes for the U50-5, with the design change and serial break points printed next to the parts that are affected. That is what stops a wrong part arriving, and what saves a second strip-down when a seal kit or bearing turns out to be the wrong size.
