Kubota KH-50, KH-50H Mini Excavator Parts Manual (BKIDA0018)

Kubota’s KH-50 and KH-50H are older rubber-track mini excavators, the kind you see doing trenching, footings, and tight utility work. The Kubota KH-50, KH-50H parts manual is what the parts counter and guys like me grab when we’re trying to sort out which seal kit, pin, or bushing actually fits a given machine. Most buyers are using it to identify the exact OEM number before they order parts or tear into a swing motor, cylinder, or undercarriage.

What this manual helps you do

• Identify the correct OEM Kubota part numbers for engine, hydraulics, swing, travel, undercarriage, and electrical components on a KH-50 or KH-50H.
• Locate specific seals, o-rings, and gasket sets inside cylinders, pumps, and motors by using the exploded view diagrams.
• Look up all the pins, bushings, shims, and hardware needed before you rebuild a boom, arm, or bucket linkage so you’re not making three trips to town.
• Cross-reference older Kubota part numbers shown in the diagrams to newer superseded numbers usually noted in the parts listings.
• Verify that what you’re about to order online actually matches the machine’s assemblies, instead of guessing from a photo and hoping it fits.

Who this is for

This parts manual is aimed at independent ag and construction mechanics, small excavation or landscape contractors, Kubota dealer parts staff, and owners keeping an older KH-50 or KH-50H alive. If you’re looking for torque specs, teardown steps, hydraulic testing, or adjustment procedures, you want the Workshop/Service Manual, not this parts catalog.

FAQ

Q: Does this cover the engine, hydraulics, and travel system, or just the boom and bucket?

A: It’s a full Kubota KH-50, KH-50H parts manual, so you’ll typically see exploded views and part numbers for the engine, hydraulic pumps and valves, cylinders, swing and travel motors, undercarriage, and electrics.

Q: Are the part numbers in here current, or will my dealer have different numbers?

A: The manual shows the OEM numbers as printed and usually notes superseded numbers, but the dealer’s system is always the final word on the latest Kubota updates.

Bottom line: If you need to identify and order the right parts for a KH-50 or KH-50H, this is the right book; if you need to repair or adjust those parts, keep looking for the WSM.
