Kubota KX71 Parts Catalog

You need the right part number the first time. Aftermarket parts lists that claim to fit a KX71 but don’t match the serial number are a waste of your money and time. That’s why you want the factory book. This is the Kubota KX71 Parts Catalog, 266 pages, direct from the manufacturer. No reprints. No third-party guesswork. Just the part numbers, quantities, serial number ranges, and interchangeability codes that Kubota engineering intended.

Crankshaft, Camshaft, and Cylinder Head Coverage

Start with the engine. The catalog breaks down the basic engine assembly into individual sections: CRANKCASE, OIL PAN, PISTON CRANKSHAFT, MAIN BEARING CASE, CAMSHAFT, CYLINDER HEAD, VALVE ROCKER ARM, CYLINDER HEAD COVER, and GEAR CASE. Each section lists the Kubota part number, quantity, and serial number applicability. If you need a new crankshaft for a KX71 built after a certain serial number, you’ll see it on the line. The cylinder head section includes valve-related components – valves, springs, retainers – with precise part numbers. Don’t rely on a generic cross-reference; this catalog gives you the exact OEM number.

Does This Parts Catalog Include Torque Specs?

No. This is a parts catalog, not a service manual. It does not list torque values, clearance specs, or assembly procedures. That information belongs in the separate Kubota KX71 Workshop Manual. What this catalog does give you is the correct part number for every fastener, gasket, seal, and component – including the valve rocker arm assembly, injection pump camshaft, and glow plug nozzle holder. If you’re rebuilding the engine, order parts from this catalog, then use the workshop manual for assembly specs. Page 3 shows the indexing for each subsystem: fuel, cooling, electrical, hydraulic. You’ll find the exact part for the water pump, dynamo, starter, and control valve spool sections.

266 Pages of Factory Part Numbers

Each page follows the same column layout: Ref. No., Part No., Description, Q’ty, S.No. range, I/C (interchangeability), and Remarks. The instructions at the start (page 1) explain the symbols. For example, a double-headed arrow means the part works forward and backward across serial numbers. A hash mark (#) means it’s not interchangeable. Pay attention to the country codes – a part may be marked EXCEPT [FR] for France but still fits the US market. That’s critical when ordering from a dealer who uses a global parts database. You can verify the part number against your machine’s serial number using the S.No. column. The catalog covers KX71 units across all variants (KTC, KCL, KTA, M.E.) where applicable.

Hydraulic System: Control Valve Spool Sections

The hydraulic section is thorough. It breaks down the pump housing, gear pump, drive motor, swivel motor, rotary joint, oil tank, and three separate control valve groups. Each control valve section lists the spool sections for travel (RH/LH), boom, bucket, arm, S/P, swivel, swing, and blade. If you need a replacement spool for the boom circuit, you’ll find the part number under Control Valve (1) with the exact spool section. The catalog also includes oil piping diagrams for suction, delivery, return, cooler, and all individual circuits (travel, swivel, swing, boom, arm, bucket, blade, confluence, cushion, S/P). Boom cylinder, arm cylinder, bucket cylinder, blade cylinder, and swing cylinder component parts are listed separately. That means you can order the correct seal kit or rod without measuring anything – just match the part number.

Understand the Country Codes Before Ordering

Look at the Remarks column. You might see a note like “EXCEPT [CA]” or “FOR [AU]”. The catalog includes a country code table on page 1: A=USA, CA=Canada, FR=France, GR=Greece, PO=Portugal, AU=Australia. If a part is marked EXCEPT [FR], it works in all countries except France – including the USA. Ignoring these codes can land you with the wrong wiring harness or emission-related component that doesn’t meet local regulations. The catalog is designed for the North American market, so most parts apply here. But double-check any electrical or emission system part for country-specific restrictions.

How do I find the part number for a crankshaft on my KX71?

Look in the PISTON CRANKSHAFT section. Match your engine serial number to the S.No. column. The part number is listed under the Part No. column.

Can I use this catalog to order parts for a KX71 that was originally sold in Canada?

Yes, but check the country codes. Canada is code CA. Some parts may be marked “EXCEPT [CA]” meaning they do not fit Canadian-spec machines. If the Remarks column is blank for that line, it fits all countries. The catalog includes Canadian-specific parts where applicable, usually noted with “FOR [CA]”. Always verify the serial number range and I/C symbol before ordering. If you see a hash mark (#) in the I/C column, the part is not interchangeable between serial number ranges, even within the same country. That’s especially common on hydraulic components that changed mid-production. When in doubt, contact your Kubota dealer with the catalog page and part number in hand – they’ll confirm fitment.

Does the catalog cover attachment parts like the bucket or blade?

Yes. Sections for BUCKET, BLADE, BOOM, ARM, and BUCKET LINK appear under FRONT ATTACHMENTS. The BUCKET section includes teeth, pins, and cutting edge part numbers.

What does the I/C column mean?

I/C stands for Interchangeability. Arrows (↔) mean the part works both forward and backward across serial numbers. A hash mark (#) means it is not interchangeable with other serial number ranges. New-for-old and old-for-new arrows indicate direction of supersession.
