Kubota KX019-4 Compact Excavator Parts Manual

The Kubota KX019-4 is a rubber-track compact excavator, the kind you’ll see on farms for drainage work, yard projects, and light construction. The Kubota KX019-4 parts manual is what I reach for when I’m trying to ID a worn pin, seal kit, or casting before I ever pick up a wrench. It’s meant for planning a repair, pricing parts, and making sure you order the right pieces from Kubota or an aftermarket source. If you’re chasing part numbers or want “x-ray vision” exploded views, this is the right type of book.

What this manual helps you do

• Identify the exact OEM part numbers for items like bucket pins, bushings, track rollers, idlers, and sprockets on the KX019-4.
• Locate every component in assemblies such as the boom, arm, swing motor, travel motors, and undercarriage using exploded diagrams.
• Look up seals, gaskets, and small hardware by quantity-per-machine so you don’t come up one O-ring short in the middle of a rebuild.
• Cross-reference older Kubota numbers to newer superseded numbers, using both revisions (BKIDA5047 and BKIDA5186) to see how parts changed over time.
• Verify that the parts you’re about to buy—OEM or aftermarket—actually match the specific KX019-4 version sitting in your yard.

Who this is for

This suits an independent ag mechanic, farm owner-operator, small contractor, or parts desk person who needs accurate Kubota numbers to keep a KX019-4 earning money. If you’re after torque specs, hydraulic test procedures, or step-by-step repair instructions, you need the Kubota Workshop/Service Manual instead, not this parts catalog.

FAQ

Q: Does this cover engine, hydraulics, and electrical parts, or just the undercarriage?

A: It covers all major assembly groups on the KX019-4, including engine-related components, hydraulic pumps and cylinders, drive and swing, undercarriage, cab/controls, and electrical parts.

Q: Are the part numbers in here current, or will my dealer say they’re out of date?

A: The manual shows the original numbers and notes superseded numbers Kubota issued up to each revision, but your dealer’s system is always the final word on the latest replacement.

Bottom line: If your main goal is to identify and order the right parts for a Kubota KX019-4 compact excavator, this parts manual is what you want; if you need how-to repair steps, keep looking for the Workshop Manual instead.
