Kubota KH-90, KH-90H Mini Excavator Parts Manual (BKIDA0017)

The Kubota KH-90, KH-90H is a rubber-track mini excavator, the kind you’ll see on small farms, construction sites, and drainage jobs. The Kubota KH-90, KH-90H parts manual is what I reach for when I’m trying to figure out exactly which pin, bushing, seal kit, or hose end belongs on one of these machines. Most folks buying this are lining up parts before a teardown, checking what’s missing on a used machine, or trying to match an old component to the right OEM number so they don’t waste money at the dealer.

What this manual helps you do

• Identify the correct OEM part numbers for engine, hydraulics, undercarriage, and upperstructure components on the KH-90 and KH-90H.
• Locate every seal, bushing, pin, and bearing in the boom, arm, bucket linkage, swing motor, and track drive assemblies before you start a rebuild.
• Look up the exact hardware, gaskets, and small fittings you’ll need so you can price them out or source aftermarket instead of paying top dealer prices.
• Cross-reference older Kubota numbers to updated part numbers shown in the catalog so the parts desk can actually order what you need.
• Verify that a used or aftermarket component matches what originally came on your machine by comparing the illustrated breakdowns and callouts.

Who this is for

This is aimed at an independent ag mechanic, farm owner-operator, small contractor, or parts person who needs exploded diagrams and part numbers, not repair instructions. If you’re after torque specs, hydraulic pressures, or step‑by‑step repair procedures, you need the Workshop/Service Manual, not this parts catalog.
