Kubota KX71 Parts Catalog – 266-Page OEM Factory Parts Breakdown

If you own a Kubota KX71 and you are tired of ordering parts that don’t fit, or spending an hour cross-referencing part numbers on some forum, this is what you need. This is the factory Parts Catalog – not a reprint, not a third-party compilation, not a generic list. It is the exact same document the dealer uses when you call in with a serial number. 266 pages of exploded diagrams, part numbers, and interchangeability codes. No guesswork.

Working on a machine that has been modified or has multiple serial number breaks? Page 1 of this catalog explains exactly how to read the column headings – Ref. No, Part No., Description, Q’ty, S.No., I/C, and Remarks. The I/C column tells you if a part swaps between older and newer serial numbers using arrows and symbols. You will not find that in a generic PDF. This is the real deal.

PISTON CRANKSHAFT Section – What You Get

Open to the BASIC ENGINE section. The PISTON CRANKSHAFT grouping (item 01S003) gives you the crank, connecting rods, bearings, and all associated hardware with factory part numbers. The same applies to the CAMSHAFT section – both the camshaft itself and its thrust plate are listed with exact part numbers and corresponding quantities. No aftermarket translation errors.

Need the CYLINDER HEAD assembly? The catalog breaks it down into CYLINDER HEAD, VALVE ROCKER ARM, and CYLINDER HEAD COVER – each with its own exploded view and part number list. The Valve components (valves, guides, seats) appear under the cylinder head grouping, clearly marked. This is a parts catalog, so it does not include torque specs or step-by-step repair instructions – but it gives you the exact part numbers to order. Combine it with a service manual for the full picture.

Does This Catalog Cover the Hydraulic System?

Yes. The catalog dedicates a huge chunk of its pages to the HYDRAULIC SYSTEM. Sections like CONTROL VALVE (1) with its component parts, SPOOL SECTION for travel, boom, bucket, arm, swivel, swing, blade – each spool section is broken into separate groups. You also get GEAR PUMP & COMPONENT PARTS, DRIVE MOTOR & COMPONENT PARTS, SWIVEL MOTOR & COMPONENT PARTS, and all the OIL PIPING lines (third line, suction delivery, return, cooler, travel, swivel, boom, arm, bucket, blade, confluence, cushion, S/P). Every hose, fitting, and seal is listed.

Other systems covered: FUEL SYSTEM (nozzle holder, injection pump, governor, stop solenoid), COOLING SYSTEM (water flange, water pump), ELECTRICAL SYSTEM (flywheel starter, dynamo, battery, switch meter, wiring), and FRONT ATTACHMENTS (boom, arm, bucket, blade, cylinders). The index on page 2 organizes everything under 12 system groups.

3 Reasons to Choose OEM Documentation Over Aftermarket

First, aftermarket parts catalogs often consolidate multiple machine models into one document, but they skip the serial number breaks and interchangeability codes that matter when a part changed mid-production. This catalog shows you exact serial number ranges – greater than or equal to, less than or equal to – using the S.No. column. Second, aftermarket sources frequently omit the “I/C” (interchangeability) symbols that tell you if a part works for older or newer machines. The factory document includes arrows (← new for old, → old for new) and a hash mark for non-interchangeable parts. Third, country codes. If you have a machine originally sold in France or Canada, the remarks column will say “except [FR]” or “[CA]” – and you will order the correct part. No aftermarket catalog bothers with that.

This is an OEM document – the same file Kubota supplies to its dealers. Period.

Instructions for Parts Books – How to Read It

The first two pages of the PDF contain the “Instructions for Parts Books” – a short guide that defines every column heading. You get the column definitions exactly as they appear in the original: REF.No, Part No., Description, Q’ty, S.No., I/C, Remarks. Then page 2 shows the ALL PRODUCT INDEX with system groups and corresponding book numbers. Page 3 begins the actual parts breakdown with BASIC ENGINE – CRANKCASE, OIL PAN, PISTON CRANKSHAFT, MAIN BEARING CASE, CAMSHAFT, CYLINDER HEAD, VALVE ROCKER ARM, CYLINDER HEAD COVER, GEAR CASE. Every part has a unique part number and quantity.

If you have ever tried to order a Crankshaft for a KX71 using only the model number, you know how easy it is to get the wrong one – there are multiple crank variants depending on serial number. This catalog tells you exactly which one fits your machine.

Does the catalog include rebuild specifications like cylinder bore limits or valve clearance?

No. This is a parts catalog – it lists part numbers, quantities, and interchangeability data. You need the service manual for specifications like torque values, clearances, and overhaul procedures. Many of those manuals are also on AutoRepairManuals.

How do I know if a part listed in this catalog is still available from Kubota?

You don’t from this document alone. The catalog was printed at a certain date – parts can be discontinued afterward. Use the part number to check current availability with your dealer or online parts supplier. The catalog gives you the correct number to start with.

You can also pair this catalog with other Kubota documents: Kubota KX71 Parts Catalog (this one), Kubota V3300-T-E2B-EPS-1 Parts Catalog – 53-Page OEM Parts Breakdown, or Kubota YU4210, YW0981 Parts Catalog – 274-Page OEM Parts Breakdown for other engines or equipment. For background on how OEM documentation supports the broader Automotive Industry Overview, the principles are the same – factory data beats reprints.
