Kubota V3307 Parts Catalog – 113 Pages of Factory Part Numbers

You have a V3307 on the stand and a rocker arm shaft bracket that’s cracked. You pull up a generic parts website, type in “rocker arm shaft Kubota,” and get six different listings with no photos. Which one fits? You don’t know. You order one, wait a week, and it’s the wrong bracket. That’s a week of downtime and a sixty-dollar paperweight. The Kubota V3307 Parts Catalog stops that waste cold. This is the same paper manual Kubota dealers use to order parts – 113 pages of exploded diagrams, OEM part numbers, and quantity callouts. No aftermarket re-engineering. No second-guessing.

Figure List: 52 Assemblies Covered

Flip to page 4 and you’ll see the full figure index. Fifty-two assemblies, from the crankcase (Fig. 1) all the way to the piston kit options (Fig. 52). Each figure is an exploded view with reference numbers keyed to the parts table on the facing page. Need a fuel injection pipe? Fig. 17. The common rail? Fig. 19. The diesel particulate filter muffler? That’s Fig. 38 through 40, including the sensor. The catalog doesn’t stop at the engine block – it covers the alternator component parts (Fig. 21), the starter (Fig. 22-23), the EGR cooler (Fig. 35), and the turbo charger (Fig. 37). If it bolts to the V3307-CR-TE4B-TLTU1, it’s in here.

Why OEM Part Numbers Matter

Page 1 of the catalog shows you exactly how to read each row: reference number, parts number, description, quantity, and a column for “I” and “R” – initial and replacement. That last column tells you if Kubota superseded the part for production changes. Aftermarket catalogs skip that column. They give you a part number that was right in 2010, but Kubota updated the seal design in 2014. You install the old seal and it leaks. I’ve torqued enough head bolts to tell you: OEM part numbers are the only numbers that matter. This catalog gives you the current factory number, no interpretation. If you’re rebuilding a cylinder head (Fig. 4), you need the right valves – inlet and exhaust (Fig. 5). The catalog lists each valve with its factory part number, quantity per cylinder, and any notes. You can order exactly what Kubota intended, not something a third-party warehouse thinks might fit. For more context on how critical OEM documentation is across the automotive industry, refer to the Automotive Industry Overview.

Kubota V3307 Parts Catalog: A Breakdown of the Diagrams

Let’s walk through a few key sections you’ll use regularly. The fuel system alone covers eight figures – supply pump (Fig. 12), fuel filter (Fig. 13-14), fuel pipe (Fig. 15), separator (Fig. 16), injection pipe (Fig. 17), electrical fuel pump (Fig. 18), and the common rail (Fig. 19). If a line cracks and pisses diesel everywhere, you can find the exact pipe assembly in two minutes. The lubrication system is equally detailed: oil pan (Fig. 2), dipstick and guide (Fig. 3), oil separator (Fig. 43), oil pipe for turbo (Fig. 44), oil pipe for side PTO (Fig. 45), and oil cooler (Fig. 46). And if you’re doing a full engine rebuild, the optional gasket kits are listed separately – upper gasket kit (Fig. 49), lower gasket kit (Fig. 50), metal kit (Fig. 51), and piston kit (Fig. 52). That’s the kind of specificity a good shop manual gives you.

Who Needs This Catalog?

If you own a piece of equipment with a V3307 – a compact tractor, a skid steer, a generator – you need this. The same engine goes into multiple brands, but the Kubota part number is the constant. DIY mechanics who do their own overhauls will save the cost of this catalog on the first mistake they avoid. Beginners can use the exploded diagrams to identify parts visually; you don’t need to be a mechanic to match a picture of a water pump (Fig. 26) to the one in your hand. Shops that service Kubota engines should have this on every bay’s tablet. I’ve seen too many techs waste billable hours cross-referencing aftermarket parts books. The Automotive Industry Overview shows how fragmented parts data can get without factory sourcing. This catalog eliminates that fragmentation.

Real-World Use Case: Ordering the Right Gasket Kit

Say you’re pulling the head off a V3307 that overheated. The head gasket is blown and you want to replace all the gaskets while you’re in there. You have two options in the catalog: Fig. 49 – Upper Gasket Kit [Option], and Fig. 50 – Lower Gasket Kit [Option]. The upper kit includes the head gasket, valve cover gasket, intake/exhaust manifold gaskets. The lower kit covers the oil pan gasket, front cover seal, and side PTO gasket. You order the wrong one and you’ll be waiting for a separate shipping for the oil pan gasket. With the catalog open to page 4 (the figure list), you can see at a glance which kit fits your job. The parts numbers are right there – you call your Kubota dealer, read them the 8-digit number, and the parts arrive in two days. That’s how you keep a machine running.

Frequently Asked Questions

Does this catalog include service procedures like torque specs?

No. This is a parts catalog – it gives you exploded diagrams and part numbers only. You need the service repair manual for torque values, clearances, and overhaul steps. The two manuals work together; this one is for ordering parts, not assembling them.

How do I find a part number using the catalog?

Start with the figure index on page 4. Find the assembly (e.g., “CYLINDER HEAD Fig. 4”), flip to that figure, identify the part in the diagram, read the reference number, then look up that reference number in the parts table to the right. The column labeled “PARTS NO.” gives you the 8- or 9-digit OEM number.

Are the part numbers still current for 2025?

Kubota updates supersessions periodically. The catalog prints the current numbers at the time of publication. Always verify with your dealer if the engine has been in service for more than five years. The “R” column on page 1 indicates replacement parts – use that as a guide.

Can I use this catalog to rebuild the entire engine?

You can identify every part you need. The catalog lists all 52 assemblies from crankcase to piston kit options. But you still need a service manual for assembly procedures, clearances, and torque specs. No shortcuts – get both.
