Kubota KH-31, KH-31KE, KH-31H, KH-31HKE Mini Excavator Parts Manual (BKIDA0015)

The Kubota KH-31, KH-31KE, KH-31H, KH-31HKE are older rubber-track mini excavators, the kind a small contractor or farm like mine keeps around for trenching, cleanup, and tight spots. The Kubota KH-31, KH-31KE, KH-31H, KH-31HKE parts manual is what you grab when you’re mid-teardown and need to see how everything stacks together or what to order before you pull pins and hoses. If you’re like me with my BX and L3901, trying to skip the dealer guesswork and order the right parts the first time, this is the book you want. Just remember: it’s for parts ID, not how-to repair steps.

What this manual helps you do

• Identify every component in the boom, arm, bucket linkage, and quick-coupler so you can order the correct pins, bushings, and shims for a tight rebuild.
• Locate seals, bearings, and internal pieces in the swing motor, travel motors, and hydraulic cylinders by exploded diagram instead of guessing from a parts counter photo.
• Look up OEM Kubota part numbers for undercarriage parts like rollers, idlers, sprockets, and track hardware before you call the dealer or shop online.
• Cross-reference older part numbers to the newer superseded Kubota numbers when something has been updated since your machine left the factory.
• Verify quantities of small stuff—o-rings, snap rings, bolts, washers, gaskets—so you buy enough to do the job once instead of making three trips.

Who this is for

This parts manual suits an independent mechanic, farm or landscape owner-operator, or Kubota parts desk that needs accurate part numbers and diagrams for KH-31 series excavators. If you’re after torque specs, teardown procedures, or hydraulic test steps, you want the Workshop/Service Manual instead, not this parts catalog.

FAQ

Q: Does this cover the engine, hydraulics, and electrical on these KH-31 series machines?

A: Yes, parts manuals like this one typically show exploded views and part numbers for the engine assembly, hydraulic system, undercarriage, and electrical components.

Q: Are the part numbers in this manual current, or does it show superseded numbers too?

A: These manuals usually list the original Kubota part numbers and often note superseded numbers, but your dealer can confirm the latest live number.

Bottom line: If your goal is to see how the machine is built and order correct Kubota parts by number, this is the right manual; if you need repair instructions, keep looking for the WSM.
