Kubota B26 Parts Catalog – 299-Page OEM Parts Breakdown

Ordering the wrong part number will cost you a day and a half of downtime. I’ve seen guys pull a cylinder head off a B26, then spend three hours on the phone trying to match a gasket set because they used an aftermarket parts lookup. This Kubota B26 Parts Catalog is the factory book – 299 pages of exploded diagrams and OEM part numbers that match what came off the line. No translations, no “fits like” claims. You turn to the section, read the ref number, cross it to the part number, and call your dealer. Done.

What This Parts Catalog Actually Covers

The table of contents reads like a tractor autopsy. Starts at the CRANKCASE and OIL PAN, then goes straight through CYLINDER HEAD, GEAR CASE, HEAD COVER, and the oil filter assembly. Every rotating assembly is broken out – CAMSHAFT AND IDLE GEAR SHAFT, PISTON AND CRANKSHAFT, the FLYWHEEL. The FUEL CAMSHAFT AND GOVERNOR SHAFT section is separate from the main camshaft because on the B26 the fuel pump drive is its own deal. You also get the NOZZLE HOLDER AND GLOW PLUG page, plus component-level breakdowns for the INJECTION PUMP and GOVERNOR. And for the cooling side: WATER FLANGE AND THERMOSTAT, WATER PUMP. The VALVE AND ROCKER ARM section has every keeper, retainer, and shim listed with a Kubota part number. Look at page 2 for the crankcase – it lists every plug, pin, and bush with weight and quantity in pounds. That’s the level of detail you’re getting.

3 Reasons to Use OEM Parts Documentation

One: aftermarket parts catalogs collapse multiple production runs into one composite number that may or may not fit your serial number. The factory catalog uses the serial number break (IC S/N) on each page – you verify before you order. Two: the part number is the legal cross-reference. If your dealer says “superseded to 1G062-01013,” you already have that in hand. Three: you get the exact quantity and weight per part. That matters when you’re rebuilding a hydraulic cylinder and the seal kit says “1 each” but you actually need two O-rings for the piston – the diagram shows it.

Where Do You Find the Part Numbers?

Every section in this Kubota B26 Parts Catalog follows the same layout. Ref number on the left, then the Kubota part number, part name, quantity, serial number applicability, weight in pounds, and any remarks. For example, the CRANKCASE page shows ref 010: 1G062-01013 COMP.CRANKCASE, qty 1, weight 66 lbs. If you’re looking for a dipstick guide or oil filter, you flip to the DIPSTICK AND GUIDE or OIL FILTER headings. The FUEL section alone covers FUEL TANK, FUEL PIPE, FUEL FILTER [COMPONENT PARTS], and the mechanical FUEL PUMP. The electrical side includes BATTERY, SWITCH, PANEL BOARD, and all the lighting circuits. No generic schematic – each component has its own breakout with part numbers.

Cylinder Head and Valve Train: No Guesswork

The CYLINDER HEAD section lists the bare head, valves, springs, seals, and rocker arm assembly. The VALVE AND ROCKER ARM page is separate and gives you the individual part numbers for intake and exhaust valves, valve keepers, and adjusting screws. If you’re doing a top-end job, you will need those shims – the catalog shows the exact thickness part number, not a range. Same with the CAMSHAFT section: it’s split between the main camshaft and the FUEL CAMSHAFT AND GOVERNOR SHAFT. You get the idle gear shaft bush, the governor gear bush – all with OEM numbers. This is the kind of reference that eliminates the “I think this is the right part” conversation.

This Manual vs. Aftermarket Parts Websites

Parts websites pull from data aggregators that often skip supersessions or combine diagrams across models. This Kubota B26 Parts Catalog is a factory-published PDF, not a scan of a scan with watermarks. The 299 pages include every assembly from the front axle frame through the ROPS/FOPS and canopy electrical wiring. You get the HST and its four component-part pages, the PTO clutch, the differential, the brake rods and pedals, and all the hydraulic lines. The LABEL [ENGLISH] and LABEL [FRENCH] pages even give you the decal part numbers. If your B26 has an option like a back buzzer kit or drawbar kit, those are listed at the back under ACCESSORIES AND SERVICE PARTS. I’ve seen shops burn a full day because they ordered a steering cylinder seal kit from a third-party site and it came with the wrong O-ring. With this catalog, you look up HYDRAULIC CYLINDER, get the part number, call your dealer, and the part shows up right.

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and weights – not tightening values.

Can I use this to rebuild the engine?

You can use it to order every part down to the last O-ring. For installation steps, you need the corresponding workshop manual. The parts catalog and the workshop manual are separate documents.

How do I know if a part is superseded?

The catalog shows the part number from the factory. If a supersession exists, your dealer will tell you. The catalog is the starting point, not the final cross-reference.

What does the weight column mean?

Each line includes the weight in pounds. That helps you verify shipping costs and confirm you’re ordering the right assembly – a crankcase weighs 66 lbs, an oil pan 2.9 lbs. If the part you receive is way off in weight, something’s wrong.

Stop burning time guessing part numbers from blurry website thumbnails. This is the factory document – 299 pages, organized by assembly, with Kubota part numbers you can trust. Access the Factory Manual from AutoRepairManuals and keep it on your tablet next to the workbench. You’ll order the right part the first time.
