Kubota KX41-2 Parts Catalog – 286 Pages of Factory Parts Data

You are holding a box of bolts from the dealer and the part number tag is missing. Now what? Grab this Kubota KX41-2 Parts Catalog and match the part by the drawing, not by memory. 286 pages of factory exploded views and part numbers. I have seen guys order a whole hydraulic pump because they guessed the wrong seal kit. That costs time and money. This catalog stops that.

Page 1 explains the column headings: REF.No, Part No., Description, Q’ty, S.No. range, and I/C interchangeability codes. That page is worth reading twice. The I/C symbols tell you if a part swaps forward or backward in serial number ranges. Ignore those and you might bolt on a part that does not fit. I have seen that happen on a KX41-2 in San Antonio three years ago. Guy used an older nozzle holder and the injector pump timing went to hell.

Crankcase and Crankshaft: The Foundation of the Engine

PAGE 2 shows the BASIC ENGINE section starts with the CRANKCASE and OIL PAN assemblies. Under that you get PISTON,CRANKSHAFT and MAIN BEARING CASE. Each page in the catalog has a reference number (like 100K0537) that ties the drawing to the parts list. Need a crankshaft? You will find it in that section with the correct part number and the serial number range it covers. The catalog also includes CAMSHAFT, CYLINDER HEAD, VALVE AND ROCKER ARM, and HEAD COVER. If you are rebuilding the top end, you get every valve guide and rocker shaft part listed. No guessing which shim goes where.

Valve and Rocker Arm: Don’t Guess the Rocker Ratio

Valve train parts are not something you can swap by sight. The KX41-2 uses specific rocker arms and valves. This catalog gives you the exact part numbers for the intake and exhaust valves, valve springs, retainers, and rocker arm assembly. Page 2 lists 01S007 VALVE AND ROCKER ARM under the BASIC ENGINE group. The accompanying drawing shows each component exploded so you can identify the single bad spring instead of buying the whole head set. That saves money if you are working on a tight budget. I have used these drawings to find a mislabeled rocker arm bolt on a similar Kubota engine. The factory drawing does not lie.

Fuel System Parts: From Injection Pump to Nozzle Holder

The FUEL system section covers NOZZLE HOLDER,GLOW PLUG, INJECTION PUMP, FUEL CAMSHAFT, FUEL PIPING, FUEL FILTER [COMPONENT PARTS], and FUEL TANK. Each component has its own page with a detailed exploded view. The STOP SOLENOID and GOVERNOR are also listed under separate line items. If your KX41-2 is hard to start or runs rough, the fuel system pages let you isolate the problem part. For example, the nozzle holder page shows the glow plug as a separate item with its own part number. You can order just the glow plug instead of the entire holder assembly. That is the kind of detail the aftermarket catalogs leave out.

Hydraulic System Breakdown: Over 40 Spool Sections Listed

Hydraulics are where this catalog really earns its keep. The CONTROL VALVE section breaks down into individual spool sections: BOOM, BUCKET, TRAVEL RH, TRAVEL STRAIGHT, S/P, TRAVEL LH, ARM, SPACER/SWING, BLADE, SWIVEL. Each spool has its own component parts page. The UNLOADER VALVE, TPSS VALVE, and CHANGE VALVE are separate sections. You also get the PUMP HOUSING, GRAR PUMP AND COMPONENT PARTS (likely a gear pump), and HYDRAULIC PUMP AND COMPONENT PARTS. Need a drive motor? There are two sections: DRIVE MOTOR AND COMPONENT PARTS (1) and (2). The ROTARY JOINT has its own page, and there is a separate ROTARY JOINT [KX41-2V] for the V-series variation. That distinction matters. The V-series uses a different swivel and control valve. Mix those up and the machine will not track straight.

What Makes This OEM Parts Catalog Different from Aftermarket?

Aftermarket parts catalogs often re-draw the pictures and leave out the interchange codes and serial number ranges. This Kubota factory catalog has I/C symbols that tell you if a part is interchangeable with older or newer serial numbers. The GRAR PUMP section (likely a gear pump) shows the correct part number for your specific serial number range. The catalog also lists country codes in the remarks column. If the remark says EXCEPT [FR], that part works everywhere but France. That means it fits your machine in the USA. I have ordered a hydraulic pump from a third-party catalog that showed the wrong part because they did not include the country code. This catalog does.

3 Reasons to Choose OEM Documentation Over Generic Parts Lists

First, the ENGINE section includes every casting: CYLINDER HEAD, GEAR CASE, WATER FLANGE, WATER PUMP, FLYWHEEL,STARTER, ALTERNATOR, and AIR CLEANER,INLET MANIFOLD. Second, the hydraulic system is broken down to the individual spool sections and even differentiates the KX41-2V variants. Third, the LABEL and WEIGHT KIT [OPTION] sections show optional parts that aftermarket lists often ignore. If you need to order a factory decal for the canopy or a weight kit for the blade, you have the right part number.

Does this catalog show where to buy parts or just the numbers?

Just the numbers. It lists part numbers, descriptions, and interchange codes. You still order through your Kubota dealer or online parts retailer.

Can I use this catalog to identify parts from a different model like the KX41-2V?

The catalog includes separate sections marked [KX41-2V] for many components such as the rotary joint, control valve, blade cylinder, track frame, and oil piping. If you have the V-series, you need to reference those specific pages. The main KX41-2 sections do not always cover the V-series parts. The catalog organizes them under the same basic system but with separate headings. For example, the OIL PIPING (BLADE) page has a [KX41-2V] version. You must check the serial number range on each page to confirm fitment. The I/C symbols also help with cross-model interchangeability, but Kubota typically separates the two variants because the hydraulic system changed. Always verify against your machine’s serial number before ordering.

If you rebuild equipment for a living or just keep your own KX41-2 running, a factory parts catalog is the only way to get the right number the first time. Access the Factory Manual from AutoRepairManuals and keep it on your shop tablet or print the pages you need for the job.
