Kubota BH90 Parts Catalog – Factory OEM Parts Breakdown for Backhoe

You are pulling a Kubota BH90 backhoe apart. The swing cylinder seal blew, and now you need the correct part number for the rebuild kit. You grab a generic aftermarket parts list, and suddenly you are cross-referencing three different websites, hoping the O-ring matches. That wastes billable time. This Parts Catalog is the factory document – 65 pages of OEM part numbers, exploded views, and interchangeability codes. No aftermarket approximations. No calling the dealer and waiting. The information is laid out exactly like Kubota prints it for its own dealers.

Every section in this book follows the same format: a picture page with numbered callouts, then a part number page listing REF. No., Part No., Description, Quantity, Serial Number range, and interchangeability symbols. The instructions on page 1 tell you how to read the columns – the <= and >= symbols, the I/C arrows, and the country codes that tell you if a part fits USA, Canada, France, or Australia. That level of detail is why you pay for factory documentation. Aftermarket catalogs skip the serial number range and interchangeability info. Then you buy the wrong part and lose a day.

Instructions for Parts Books – How the Manual Is Organized

The first two pages of this catalog explain the column headings and the country code system. If the Remarks column says “EXCEPT [FR]”, that part works everywhere except France – which means it is correct for the USA. You need that information when ordering parts for a machine that may have been sold in multiple markets. This is not a reprint of generic data; it is the original factory document from Kubota. The catalog also includes a product index that lists every assembly group with the page reference (e.g., Ref. BH90 Page 65061). You can jump straight to the section you need.

BH90 Main Frame, Sub Frame, and Swing Frame Sections

The chassis breakdown covers the MAIN FRAME, SUB FRAME, and SWING FRAME. Each assembly has its own part number and exploded view. The main frame (01B001) and sub frame (01B005) are listed with part numbers like 100A0206. The swing frame (01B010) includes the pivot pins and bushings. If you are repairing a cracked frame or replacing bushings, you get the exact OEM part number without guessing. The manual also includes the SWING CYLINDER assembly – critical for aligning the swing bracket. Do not trust aftermarket diagrams that show generic cylinders. Get the factory part number.

What Parts Are Covered in the Control Valve Assembly?

The CONTROL VALVE section lists the main valve body (01B200) and the component parts (01B210). The valve assembly controls all five hydraulic functions: swing, boom, dipper, bucket, and stabilizer. If you need a spool, spring, or seal for the Valve, the component parts breakdown shows every piece. The hydraulic hose sections follow – INTAKE, INLET/OUTLET, SWING, BOOM/DIPPER, BUCKET, and STABILIZER – each with separate part numbers. No more guessing which hose goes where. The catalog even lists the hose routing by function.

5 Cylinder Component Breakdowns: Swing, Boom, Dipper, Bucket, Stabilizer

This catalog contains separate component parts sections for each Cylinder: SWING, BOOM, DIPPER, BUCKET, and STABILIZER. These are not generic seal kits. Each cylinder section (e.g., CYLINDER(BOOM) [COMPONENT PARTS]) lists every piston, rod, gland, seal, and O-ring with the OEM part number. You can order exactly what you need without buying a whole cylinder. The stabilizer cylinder also has its own breakdown. With 65 pages of data, you get the complete picture for the entire hydraulic system.

Factory Parts Catalog: Why It Beats Aftermarket

Aftermarket parts catalogs often combine multiple models into one book, leave out serial number breaks, and ignore country-specific variations. This OEM catalog tells you exactly which serial number range a part fits. If the I/C column shows a double arrow, the part is interchangeable forward and backward. If it shows a #, it is not. You also get the MOUNT KIT sections (AB and C-F) – critical when bolting the BH90 onto a tractor. The Label section includes caution and operation decals. Everything is original factory format, not a scanned and OCR’d mess.

Frequently Asked Questions

Does this parts catalog include service procedures like torque specs?

No. This is a parts catalog, not a service manual. It provides part numbers and exploded views only. For overhaul procedures and torque values, you need the factory service manual.

How do I use the REF. No. column?

The REF. No. matches the numbered callouts on the exploded view picture page.

What do the country codes in the Remarks column mean?

Country codes like A (USA), CA (Canada), FR (France) indicate which markets a part is intended for. If the Remarks say “EXCEPT [FR]”, the part works in all countries except France – which means it will work here in the USA. This is critical when ordering seals or hydraulic components that may have different specifications overseas. Kubota builds machines for multiple regions, and the catalog accounts for that. Always check the Remarks before ordering.

Can I order parts directly from this catalog?

Yes. Use the Part No. column to order from any Kubota dealer or online parts supplier. The catalog gives you the exact OEM number so you get the right piece the first time.
