Kubota KX101-3ALPHA4 Compact Excavator Parts Manual (BKIDA5126)

The Kubota KX101-3ALPHA4 is a rubber-track compact excavator, the kind that ends up doing trenching, service work, and light construction. The Kubota KX101-3ALPHA4 parts manual is what mechanics, parts counters, and owner-operators grab when they need to see how the machine is built and what part numbers to order. People usually use it to plan a cylinder reseal, chase down the right pins and bushings, or make sure they order every O-ring and gasket before tearing into a hydraulic or swing component. This is not a repair/WSM book; it’s the illustrated parts catalog.

What this manual helps you do

• Identify the exact OEM Kubota part numbers for engine, hydraulic, travel, and swing components on the KX101-3ALPHA4 before you order anything.
• Locate every seal, bushing, pin, and small hardware piece in the boom, arm, bucket, and undercarriage assemblies using exploded diagrams.
• Look up the correct seal kits and internal parts when rebuilding hydraulic cylinders, pumps, valves, and track motors.
• Cross-reference older or superseded Kubota numbers shown in the diagrams to what your dealer now supplies.
• Verify that the parts on your machine match the illustrated breakdowns so you don’t get caught with the wrong hoses, fittings, or brackets mid-repair.

Who this is for

This parts manual is aimed at independent mechanics, Kubota dealer parts staff, fleet maintenance, and owner-operators who do their own repairs. If you’re after torque specs, teardown steps, or adjustment procedures, you need the Kubota Workshop Manual, not this BKIDA5126 parts catalog.
