Kubota L3300DT Parts Catalog – Factory Part Numbers, No Guessing

If you are turning wrenches on a Kubota L3300DT and you are tired of cross-referencing aftermarket part numbers that land you with the wrong bearing or piston ring, this Kubota L3300DT Parts Catalog is what belongs on your bench. It is a 350-page factory document from Kubota, not a third-party reprint. I have seen parts catalogs where the illustration is too dark to read the callouts – this one keeps the contrast clean so you can match the part number to the exploded view without squinting.

Engine Section: Crankshaft, Cylinder, and Valve Train

Inside the Engine section you will find the CRANKCASE, OIL PAN, PISTON AND CRANKSHAFT, MAIN BEARING CASE, and both FLYWHEEL variants (with and without independent PTO). The CYLINDER HEAD, VALVE AND ROCKER ARM, and CAMSHAFT are each given their own two-page spread. Every part is listed with the original Kubota part number, the quantity used, and the serial number range it applies to. Need the correct valve spring or a camshaft bushing? You will find the exact factory number without having to call a dealer and wait.

Fuel System Components: Injection Pump and Camshaft

The FUEL system coverage includes the FUEL CAMSHAFT, INJECTION PUMP (with component parts), NOZZLE HOLDER/GLOW PLUG, FUEL TANK, FUEL PIPE AND FUEL FILTER, plus the FUEL FILTER component parts. This is valuable when the injection pump needs a rebuild kit – you get the part numbers for the delivery valve, plunger, and head rotor from the same page that shows the exploded view. No mixing up of old vs. new serial number breaks.

Transmission and Drivetrain: GST Type Coverage

This catalog covers 48 pages worth of transmission components, including CLUTCH HOUSING [GST TYPE], MID CASE [GST TYPE], HYDRAULIC CLUTCH [GST TYPE], SHUTTLE SHAFT [GST TYPE], RANGE GEAR SHAFT [GST TYPE], and the MAIN GEAR SHIFT FORK [GST TYPE]. If your L3300DT has the GST transmission, you need these specific pages. The manual also breaks down the REAR DIFFERENTIAL, REAR AXLE, and multiple rear wheel options (12.4-24, 420/70-24, 13.6-16, etc.). There is a separate section for FRONT AXLE, FRONT DIFFERENTIAL, and PROPELLER SHAFT – handy when you are replacing u-joints or axle seals.

How the Catalog Organizes Part Numbers

The Instructions for Parts Books page explains the column headers: REF.No links to the picture, Part No. is the Kubota factory number, Q’ty tells you how many you need, and S.No. gives the serial number range using ≤ and ≥ symbols. The I/C column shows interchangeability with arrows and hash marks. If the remarks column says “EXCEPT [FR]” that part works in the USA but not in France. This is the kind of detail you only get from a factory document, not from an aftermarket parts software that lumps all years together.

Source Validity: OEM vs. Aftermarket Documentation

I have had to explain to too many shop owners why ordering from an aftermarket parts database cost them a comeback. Aftermarket catalogs sometimes use superseded numbers without showing the old-new interchange. This Kubota Parts Catalog shows the interchangeability codes explicitly – a left arrow for “new for old” and a right arrow for “old for new”. It also includes country codes (A for USA, CA for Canada, FR for France) so you know if that part is the correct one for your region. There is no guesswork about which injection pump fits a specific serial number break.

Frequently Asked Questions

Does this catalog include the engine serial number range?

Yes. Each part in the ENGINE section is listed with a serial number range (≤ and ≥) so you order the correct parts for your L3300DT block.

How do I read the interchangeability codes in the columns?

The I/C column uses symbols: a left-right arrow (↔) means the part fits both older and newer serial numbers; a hash mark (#) means it does not interchange; a left arrow (←) means new part replaces old; a right arrow (→) means old part is superseded by new. The Remarks column may also include country codes such as EXCEPT [FR], meaning the part works in all countries except France. For example, a starter listed with I/C ↔ and remark “EXCEPT [CA]” would fit your USA-spec L3300DT but not Canadian-spec units. Understanding these codes keeps you from ordering a component that looks identical but has a different thread pitch or mounting flange.

Stop wasting time on parts that don’t fit. Access the Factory Manual and get the exact part numbers Kubota intended for your L3300DT. That is the difference between a Saturday afternoon job and a Monday morning comeback.
