Kubota KX41-2 Parts Catalog

You’ve got a KX41-2 mini excavator torn down to the crankcase and you’re staring at a pile of parts. The local dealer wants you to bring the old part in for matching, but you don’t have time for that. The aftermarket catalogs online give you a blurry picture and a part number that might be right. That’s where this Kubota KX41-2 Parts Catalog changes your day. It’s 284 pages of factory-issued exploded diagrams and part numbers, not a reprint or a scan of a scan. Every nut, every seal, every spool section is listed with the exact Kubota part number, quantity, and interchange code. No guessing if a camshaft from a different serial range will fit.

Crankshaft and Piston Group: Finding the Right Part Number

The table of contents lists a section called PISTON,CRANKSHAFT. That’s the chapter you need when the engine is apart and you’re trying to order a rod or a ring set. Each page in this catalog has a reference number that ties the picture page to the part number page. The heading at the top of the picture page is the same as the part number page, so you won’t get lost. The column headers are straightforward: Ref. No., Part No., Description, Q’ty, S.No. range, I/C (interchangeability), and Remarks. If the S.No. column says your serial number is >= the number shown, the part fits. If it says <=, same deal. And the I/C column tells you if the part swaps between old and new production. You don't need to call the dealer to decode that.

Page 3 of the catalog shows the ALL PRODUCT INDEX with item numbers for BASIC ENGINE, FUEL SYSTEM, COOLING SYSTEM, and the rest. That index is how you jump directly to the group you need. For example, the camshaft is listed under BASIC ENGINE – CAMSHAFT with the book number 100A0198. Every section in that list uses the same book number, so you know it’s all part of the same publication. That’s a detail aftermarket catalogs never give you.

Fuel System: Injection Pump and Nozzle Holder Breakdown

Under FUEL SYSTEM the catalog breaks out NOZZLE HOLDER,GLOW PLUG and then a separate section for NOZZLE HOLDER [COMPONENT PARTS]. That’s critical when you need a glow plug tip or a nozzle seat but don’t want to buy a whole holder assembly. Same for the injection pump – there’s a main section and a component-parts section. The FUEL CAMSHAFT is listed separately, which makes sense because those cam lobes wear and you replace them independent of the pump body. The catalog even lists the GOVERNOR and STOP SOLENOID with their own part numbers. If you’re doing a pump rebuild, you need the factory breakdown to order the right springs and shims.

Hydraulics: Spool Sections and Control Valves – No More Guesswork

The hydraulic system takes up a big chunk of this catalog. Sections like SPOOL SECTION (BOOM), SPOOL SECTION (BUCKET), SPOOL SECTION (TRAVEL LH), and SPOOL SECTION (TRAVEL STRAIGHT) are all listed individually. Each spool section has its own part number and quantity. If you’ve ever rebuilt a control valve on a mini excavator, you know how easy it is to mix up a boom spool with a travel spool. The catalog keeps them separate. There’s also CHANGE VALVE, MULTI VALVE, and TPSS VALVE with component parts breakdowns. The OIL PIPING sections (suction, delivery, return, travel LH/RH, swivel, swing, boom, arm, bucket, blade) are each diagrammed so you can trace a hose leak back to the exact replacement hose part number.

Source Authenticity: Why This OEM Catalog Beats Aftermarket PDFs

I’ve seen my share of aftermarket parts lists that cram a blurry picture of a Crankshaft and then give you a generic number that crosses to three different models. That doesn’t work when you need a main bearing for a specific serial range. This catalog comes straight from Kubota’s factory documentation. The page headers, the column definitions, the country codes – it’s all original. Page 1 explains how to read the interchangeability codes: a double-arrow (↔) means the part works for older and later serial numbers; a hash (#) means not interchangeable. The aftermarket manuals skip that. They also ignore the country codes. If the remarks column says “EXCEPT [FR]”, that part fits everywhere except France. That matters if you’re in the USA (code A) and you order a part intended for the Canadian market (CA) – you might get the wrong emissions component. This catalog spells it out.

FAQ

Does this catalog include engine valve specifications like seat angles or spring pressures?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and interchange codes for the valve and rocker arm group, but it does not include tolerances or rebuild specs.

How do I use the serial number range on each part?

Find the S.No. column on the part number page. If your machine’s serial number is greater than or equal to the number shown, the part fits. If it’s less than or equal, same deal. The I/C column then tells you if that part interchanges across range breaks. For example, a crankshaft listed with S.No. >= 10001 means it fits machines from serial 10001 and up. If the I/C shows a double arrow, the same part also works on older machines. This prevents ordering the wrong piston when Kubota made a running change.

If you need to identify parts for an engine rebuild – cylinder head, camshaft, valve train, fuel system, or the entire hydraulic stack – this catalog puts every part number on paper. Download the Factory Manual and work from the same diagrams the dealer uses.

Kubota KX41-2 Parts Catalog – The Only Reference You Need for Parts Orders

If you’ve ever ordered a part for a Kubota KX41-2 and got the wrong one because you guessed at the serial number break, you know the pain. That’s why this Kubota KX41-2 Parts Catalog exists. It’s the same 284-page book the dealer parts counter uses—direct from the factory print, not a third-party rehash. No guesswork on what fits your machine’s serial number range. No wondering if the part number changed mid-year. This document gives you the exact exploded view, the part number, and the interchangeability code.

Engine Group: Crankshaft, Camshaft, Cylinder Head, and Valve Train

Starting at the bottom end, the catalog breaks down the CRANKCASE, OIL PAN, and PISTON/CRANKSHAFT sections. You get separate exploded diagrams for the MAIN BEARING CASE and the gear train. Moving up, the CAMSHAFT and CYLINDER HEAD sections show every valve, rocker arm, and head cover bolt with its own part number. The manual’s page 3 lists these groups under “BASIC ENGINE” – note the book number 100A0198 applies to all those sections. If you need a valve stem seal or a camshaft gear, you look up the REF. No number, no guess.

Fuel system coverage includes the NOZZLE HOLDER, GLOW PLUG, SPEED CONTROL PLATE, STOP SOLENOID, GOVERNOR, INJECTION PUMP, and even the FUEL CAMSHAFT. These are the parts that keep that little diesel running. The catalog also covers the WATER PUMP, FLYWHEEL/STARTER, ALTERNATOR, and all electrical components. For the top end, the CYLINDER HEAD and VALVE AND ROCKER ARM sections show every shim, spring, and keeper. You won’t find a single torque spec here—this is a parts catalog, not a service manual. But you will find the exact part number for the crankshaft seal, the fuel injection pump assembly, and the camshaft thrust plate.

Fuel System Diagrams: Injection Pump and Fuel Camshaft

The FUEL SYSTEM pages (sections 01S013 through 01S020) give you component-level breakdowns. The NOZZLE HOLDER is shown separately from its component parts. The INJECTION PUMP gets its own drawing, and the FUEL CAMSHAFT is listed with its bearing and gear. If your KX41-2 has a fuel leak, you need the right O-ring from the injection pump component parts page. The catalog also covers FUEL PIPING, FUEL FILTER component parts, and the FUEL TANK. Without this book, you’d be flipping through generic catalogs hoping the threads match. Not smart.

Read the Column Headings on Page 1

Before you start flipping, understand the column definitions printed on page 1. REF.No points to the callout in the exploded view. Part No. is the assigned number. Description tells you what it is. Q’ty is how many you need. S.No. gives the serial number range where that part fits—pay attention to the ≤ and ≥ symbols. I/C shows interchangeability: ↔ means it works both ways, # means not interchangeable, ← means supersedes old part, → means old part supersedes new. The Remarks column may say “EXCEPT [FR]” – that means it fits all countries except France, which is fine for US machines. Ignore these codes and you’ll order a part that doesn’t fit.

Why 284 Pages of OEM Part Numbers Beat a Generic Cross-Reference

Generic aftermarket parts catalogs combine numbers from multiple manufacturers and drop the serial number breaks. That’s fine for a lawnmower, not for a $30,000 mini excavator. This OEM book covers every system on the KX41-2: BASIC ENGINE, AIR INTAKE, EXHAUST, FUEL, COOLING, ELECTRICAL, HYDRAULIC, FRONT ATTACHMENTS, TRACK FRAME, SWIVEL FRAME, OPERATOR’S PLATFORM, and ACCESSORIES. The hydraulic section alone has 35+ pages of spool sections, control valves, oil piping diagrams, and cylinder component parts. You get every hose, fitting, and seal drawn exactly as it came from Kubota. No guessing.

If you are rebuilding a drive motor or replacing a blade cylinder, the catalog shows the exact seal kit part number. The boom, arm, bucket, and swing cylinders are all broken down with component parts. The track frame section includes the idler, track roller, and crawler. Even the operator’s platform canopy, seat, instrument panel, and labels are covered. This is not a reprint; it’s the factory PDF scanned from the original.

Frequently Asked Questions

Is this the same manual the dealer uses?

Yes. It’s a direct OEM scan of the Kubota factory parts catalog. Same part numbers, same exploded views, same interchange codes.

Does this include torque specs or repair procedures?

No. This is a parts catalog, not a service manual. It lists part numbers and quantities for ordering. You need the separate service manual for torque specs and removal steps.

Can I use this to order parts online?

Yes. Match the part number from the catalog to your online retailer. Always verify your serial number against the S.No. column before ordering to avoid returns.

What if my serial number falls between the ranges shown?

Look at the I/C column. If it shows ↔ (bidirectional arrow), the part works for earlier and later serial numbers. If it shows ← or →, supersession applies. If it shows #, the part is not interchangeable with other ranges. When in doubt, call your dealer with your serial number and the part number from this catalog.
