Part of the Kubota Parts Manuals.
This is the Kubota parts catalog for the BH90 backhoe attachment, a 65-page PDF you download and keep. It breaks the backhoe into its assemblies: the main frame, sub frame, swing frame, boom, dipperstick, bucket and stabilizer, plus the control valve, hydraulic hoses and every cylinder, each shown as an exploded diagram with Kubota part numbers.
Use it to identify the exact part before you order. Match a worn pin, bushing, seal, cylinder or valve part to its number, and use the serial-number columns to confirm the right version for your machine.
The catalog details the control valve and its component parts, the swing, boom, dipper, bucket and stabilizer cylinders, the full set of hydraulic hoses, and the tractor mount kits, making it the reference for any BH90 repair or parts lookup.
