Kubota KX61-2 Parts Catalog – 321 Pages of Factory Part Numbers

If you have ever held a part in your hand and wondered whether it was the correct revision, or stood at the dealer counter with a blurry screenshot, this is the document that kills the guesswork. This is the Kubota KX61-2 Parts Catalog, 321 pages of OEM drawings and part numbers. No aftermarket reprints, no third-party photocopies. This is the same binder Kubota dealers pull from when you walk in.

Parts Identification: The ALL PRODUCT INDEX

Page 2 lays out the ALL PRODUCT INDEX for the KX61-2. It breaks the machine into 12 system groups: BASIC ENGINE, AIR INTAKE, EXHAUST, FUEL, COOLING, ELECTRICAL, HYDRAULIC, FRONT ATTACHMENTS, TRACK FRAME, SWIVEL FRAME, OPERATOR’S PLATFORM, and ACCESSORIES. If you need to find the part that sits inside the cylinder head, you go to BASIC ENGINE. If you are tracing a fuel leak, you jump to FUEL SYSTEM. The index is not a suggestion—it is the map.

Crankshaft, Camshaft, and Valve Train: Section Breakdown

Under BASIC ENGINE you will find sections like PISTON,CRANKSHAFT, CRANKCASE, CAMSHAFT, CYLINDER HEAD, and VALVE AND ROCKER ARM. Each section lists the factory part number, the description, the quantity used, and the serial number range for interchangeability. The column headers explained on page 1 tell you exactly what Ref.No, Part No., Description, Q’ty, S.No., and I/C mean. I/C codes tell you if a part is forward- or backward-compatible. That matters when you order a Crankshaft for a machine that had a mid-production update.

Fuel System: From Nozzle Holder to Injection Pump

The Fuel system sections cover NOZZLE HOLDER,GLOW PLUG, SPEED CONTROL PLATE, STOP SOLENOID, GOVERNOR, INJECTION PUMP, and FUEL CAMSHAFT. Each has its own component parts breakdown. If you are rebuilding an injection pump, you need the component parts section to see every seal, spring, and plunger with the correct Kubota part number. Aftermarket catalogs leave out the country codes. This manual includes them—check the Remarks column for EXCEPT [FR] or [CA] notes. That means a part fitted for the US market may differ from a Canadian or French market machine. Ignore that and you order the wrong pump.

Hydraulic System: Spool Sections and Control Valves

This catalog covers the full hydraulic system: PUMP HOUSING, PISTON PUMP AND COMPONENT PARTS, DRIVE MOTOR, SWIVEL MOTOR, CONTROL VALVE, and multiple SPOOL SECTIONS (BUCKET/SWIVEL, BOOM 1, TRAVEL RH, TRAVEL LH, BOOM 2, ARM, S/P, TRAVEL STRAIGHT, SWING/BLADE). If you have ever disassembled a spool section and lost the order of the O-rings, the exploded view on the picture page paired with the part number page saves you a trip to the dealer. Page numbers are not repeated, but the reference numbers in the table match the drawing. You trace the part, write down the number, and order it. Period.

Source Validity: OEM vs. Aftermarket Documentation

Aftermarket part catalogs often use generic drawings and omit the I/C codes. That is how you end up ordering a valve that fits serial number 10001-20000 when your machine has serial number 20500. This catalog uses the same country codes and interchangeability symbols as the dealer system: ↔ for interchangeable, # for not interchangeable, ← for new superseding old, → for old superseding new. If you rely on a third-party PDF, you are gambling. This is the factory PDF—321 pages, scanned from the original Kubota print.

Related manuals you should pair with this catalog: the Kubota KX61-2 Service Manual gives you the torque specs and repair procedures. The Kubota KX61-2 Parts Catalog – 260-Page OEM Parts Breakdown covers a different revision? Actually this IS the 321-page version, but there is also a Kubota V3300-T-E2B-EPS-1 Parts Catalog – 53-Page OEM Parts Breakdown if you work on the engine standalone.

Frequently Asked Questions

Does this Parts Catalog include torque specifications for the cylinder head bolts?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and interchangeability. Torque values are in the service manual.

How do I read the “S.No.” column?

The serial number range tells you which machines the part fits. ≥ means your serial number must be greater than or equal to that number. ≤ means lesser than or equal. If you ignore it, you will order a part that does not fit.

Can I use this catalog to order parts for a Kubota KX61-2 that was built for the Canadian market?

Yes, but watch the Remarks column for country codes. If a part says EXCEPT [CA], that part is not for Canadian machines. The catalog covers US (A), CA, FR, GR, PO, AU. Read the notes on page 1.

What is the difference between “↔” and “#” in the I/C column?

↔ means the part is interchangeable across the serial number range shown. # means it is not interchangeable—you must use the exact serial number range. Do not substitute.

Stop ordering parts by guess and by golly. Access the Factory Manual and get the right number the first time. Your machine will thank you, and your wallet will too.
