Kubota U15-3 Mini Excavator Parts Manual (BKIDA0306)

The Kubota U15-3 is a small rubber-track mini excavator you’ll see on farms, around yards, and on small contractor jobs. The Kubota U15-3 parts manual is what parts counters, farm shops, and guys like me reach for when we’re trying to figure out exactly which pin, seal kit, or hose end belongs on a specific spot. If you’re planning a cylinder reseal, undercarriage refresh, or just want the right part on the bench before you tear into it, this is the book you use. It’s not a repair/WSM manual and won’t tell you how to do the job, just what parts are in it.

What this manual helps you do

• Identify the correct OEM numbers for U15-3 boom, arm, and bucket pins, bushings, and linkages before you order anything.
• Locate every seal, wear ring, and o‑ring in the U15-3 hydraulic cylinders, pumps, control valves, swing motor, and travel motors for rebuild planning.
• Look up the exact undercarriage components on your U15-3—track rollers, idlers, sprockets, and track-related hardware—so you don’t guess at parts.
• Cross-reference older Kubota U15-3 part numbers with updated superseded numbers shown in the catalog, then confirm pricing or substitutions with your dealer.
• Verify small but critical items like bolts, nuts, snap rings, filters, and gaskets so you can source them cheaper locally or online instead of only through the dealer.

Who this is for

This parts manual is aimed at an independent ag mechanic, farm owner-operator, small contractor, or Kubota parts desk trying to identify and order the right U15-3 components. If you’re looking for torque specs, troubleshooting steps, or “how-to” repair procedures, you want the Kubota U15-3 Workshop/Service Manual instead, not this parts catalog.

FAQ

Q: Does this cover the engine, hydraulics, and electrics on the U15-3?

A: Yes, a Kubota U15-3 parts manual typically shows exploded diagrams and part numbers for engine assembly, hydraulic system, undercarriage, and electrical components.

Q: Are the part numbers in this manual still current?

A: The manual shows the original OEM numbers and usually notes superseded numbers, but I always tell folks to have the dealer run your chosen number to confirm the latest Kubota update.

Bottom line: If you already know how to wrench and just need clear diagrams and correct Kubota U15-3 part numbers to save time and money, this parts manual is exactly what you want; if you need step‑by‑step repair instructions, keep looking for the WSM.
