Kubota B2150E Parts Catalog – 272-Page OEM Parts Breakdown

If you’ve ever ordered a Kubota B2150E Parts Catalog lookup from a third-party site and got a mismatched crankshaft because they listed a generic part number, you know the frustration. This is the real thing — a factory PDF from Kubota, not an aftermarket rehash. 272 pages, scanned from the original print. No cross-referencing nonsense. You get the part number Kubota assigned at the factory, with serial number ranges and country codes that tell you exactly where that part fits. Page 1 explains how to read the columns: Ref.No, Part No., Description, Q’ty, S.No., I/C (interchangeability), and Remarks. Page 2 gives you the full product index — everything from the engine through the fuel system, transmission, hydraulics, and accessories.

Kubota B2150E Parts Catalog: What You Get in 272 Pages

This isn’t a service manual — there are no torque specs or repair procedures here. It’s a parts book. That matters when you’re tearing down a cylinder head and need the exact valve stem seal part number, or you’re rebuilding the injection pump and need the correct nozzle holder assembly. The catalog organizes everything by system: CRANKCASE, OIL PAN, PISTON/CRANKSHAFT, MAIN BEARING CASE, FLYWHEEL, CYLINDER HEAD, VALVE/ROCKER ARM, NOZZLE HOLDER, CYLINDER HEAD COVER, INLET MANIFOLD, AIR CLEANER, EXHAUST MANIFOLD, MUFFLER, CAMSHAFT, GEAR CASE, WATER PUMP, WATER FLANGE/THERMOSTAT, FUEL CAMSHAFT, INJECTION PUMP, and dozens more sections. Each component group has an exploded view on one page and the corresponding part-number table on the facing page. You match the reference number from the picture to the row in the table. Simple, direct, no guesswork.

Engine Assembly Breakdown: Crankshaft, Cylinder, Valve, and Camshaft Sections

The engine section alone covers 20+ groups. For the short block you’ll find CRANKCASE (part of the cylinder block), OIL PAN, PISTON/CRANKSHAFT (pistons, rings, wrist pins, connecting rods, and the crankshaft itself), MAIN BEARING CASE (main bearing shells and thrust washers), FLYWHEEL (including ring gear and bolt sets), and CYLINDER HEAD (valve guides, seats, springs, and the complete head gasket kit). The VALVE/ROCKER ARM section lists intake and exhaust valves, valve keepers, rocker arms, shafts, and the adjustment screws. CAMSHAFT gets its own page — part numbers for the cam itself, the bearings, and the thrust plate. If you need a camshaft for a B2150E, this catalog gives you the Kubota factory part number, not some aftermarket equivalent that might have different lobe profiles.

Fuel System Components: From Injection Pump to Fuel Filter

Fuel system parts are notorious for being misordered because people assume the injection pump from a V1505 will cross over. It won’t. This catalog lists the FUEL CAMSHAFT, INJECTION PUMP (assembly and component parts), ENGINE STOP LEVER, SPEED CONTROL PLATE, GOVERNOR, ACCELERATOR LEVER, FUEL TANK, FUEL PIPE 1 and FUEL PIPE 2, the FUEL FILTER, and the FUEL CAMSHAFT separate from the injection pump. Each line includes the S.No. range so you know if your tractor’s serial number falls within the production run. The country codes in the remarks column tell you if a part is specific to the US (A) or Canada (CA). If you see EXCEPT [FR], that part works everywhere except France — so it’s fine for North America.

Does This Catalog Cover the Hydraulic System and Drivetrain?

Yes — the back half of the book covers everything from the clutch through the transmission, rear axle, brakes, steering, and hydraulics. You get CLUTCH (disc, pressure plate, release bearing, and pedal linkage), CLUTCH HOUSING, TRANSMISSION CASE and COVER, all the shafts (1ST through 7TH, FRONT DRIVE SHAFT, PTO SHAFT, MID PTO, FRONT PTO option), forks and levers, REAR DIFFERENTIAL, DIFF.LOCK PEDAL, REAR AXLE and AXLE CASE, REAR WHEEL sizes (8.3-24, 12.4-16, 13.6-16), BRAKE assemblies, FRONT AXLE/KNUCKLE ARM, FRONT WHEEL HUB, and FRONT WHEEL sizes (4.00-12, 6.50-12, 23 x 8.50-12). The hydraulic section lists the HYDRAULIC GEAR PUMP (with component parts), all pipes (PS, suction, delivery/return), the HYDRAULIC BLOCK, CONTROL VALVE (three different assemblies: CONTROL VALVE1, 2, 3 component parts), LIFT ARM, HYD.CYLINDER CAP, TOP LINK, LOWER LINK/LIFT ROD, CHECK CHAIN, and HITCH. If you’re rebuilding the lift arms or replacing a control valve spool, the part numbers here are the ones Kubota stamped on the casting.

Why OEM Documentation Beats Aftermarket Parts Lists

I’ve seen aftermarket catalogs list a part that looks right in the picture but turns out to be an inch too short because the publisher used a generic drawing. The Kubota factory parts book uses the same exploded diagrams that the dealer parts counter uses. The I/C symbols tell you if a part is interchangeable with older or newer serial numbers (↔ means it works both directions, # means not interchangeable, ← means new replaces old, → means old replaces new). That’s critical when you’re sourcing a part for a B2150E that might have been produced across multiple serial number breaks. Aftermarket books skip that detail — and that costs you time and money.

How do I use the reference numbers correctly?

Go to page 1 for the column definitions. Match your tractor’s serial number to the S.No. column before ordering.

Does this catalog include gasket kit part numbers?

Yes, under the engine section you’ll find both UPPER GASKET KIT and LOWER GASKET KIT. Each kit has its own part number and is shown in an exploded view. The upper kit covers the cylinder head, valve cover, intake/exhaust manifold gaskets, and more. The lower kit includes oil pan, timing cover, and rear main seal. Always check the I/C symbol to confirm the kit fits your serial number range. The catalog also includes component-level part numbers (e.g., individual valve stem seals) so you can buy exactly what you need instead of a full kit.

Ordering the wrong part because a website said “fits B2150E” is a waste of your time and money. This catalog removes the guesswork. You get the exact part number that Kubota stamped on the box. When you need a crankshaft, cylinder head, valve, camshaft, fuel injection component, or any other engine part, open this PDF and cross-check your serial number. Then call your dealer with confidence. Automotive Industry Overview”>
