Kubota V3800DI-T-E3B-TLTU-1 Parts Catalog – 108-Page OEM Parts Breakdown

If you’ve ever ordered a part for one of these engines and ended up with the wrong camshaft because the aftermarket catalog didn’t show the compatibility marks, you’ll appreciate this book. This is the genuine Kubota V3800DI-T-E3B-TLTU-1 Parts Catalog—108 pages of factory exploded diagrams and part numbers, not a third-party rehash. I’ve been turning wrenches for 28 years, and nothing wastes time like a part that doesn’t fit because someone copied the wrong reference number. This document gives you the same information that Kubota dealerships use.

What This Parts Catalog Actually Covers – Engine and Beyond

This catalog breaks down the entire V3800DI-T-E3B-TLTU-1 engine into numbered figures: Cylinder head (Fig. 4), inlet valve and exhaust valve (Fig. 5), piston and Crankshaft (Fig. 11), Camshaft and idle gear shaft (Fig. 12), plus the injection pump, turbocharger, EGR components, and more. Each figure has a corresponding parts list with OEM part numbers, quantities, and compatibility codes. Need the right fuel injection pump? Figure 14 through 16 cover the pump unit, housing, and injection pump assembly—with boost and non-boost variants clearly marked. You get the same level of detail for the alternator, starter, water pump, and even the labels and operator’s manual (Fig. 50).

How to Read the Compatibility Symbols – Don’t Guess

Page 0-1 (the “Reference” page) explains the Japanese- and English-language symbology. You’ll see letters like N, Q, R, S, K, W, Z next to part numbers. R means the new and old parts are interchangeable both ways. K means the part has no interchangeability by itself but works when replaced as a set. Ignore these marks and you’ll end up with a valve that won’t seat or a Fuel pump that leaks at the mounting flange. The catalog also includes level indicators (Y marks) that show parent-child relationships within an assembly—critical when you’re ordering a sub-assembly versus an individual component.

Sourcing the Correct Cylinder Head and Valve Parts

Figure 4 (cylinder head) and Figure 5 (inlet valve and exhaust valve) list each valve guide, seat, spring, and retainer with Kubota part numbers. No guessing if a generic valve from the auto parts store will work—the catalog tells you exactly what was fitted at the factory. The same goes for the rocker arm shaft (Fig. 6) and head cover (Fig. 7). If you’re rebuilding the top end, you need these figures open on your bench, not a PDF from a third-party site that might have mixed up the 12‑valve and 16‑valve versions.

Fuel Injection Pump – Interpreting the Parts Table

Take Figure 29 (listed as “FUEL INJECTION PUMP (W/BOOST)” in the English section). The table on page 1 lists ref. no. 1 as part number 12995-51291 (one pump) and 12995-51301 (another variant). The columns A through F correspond to product symbols and serial number ranges—for example, (A#E/00185) means the change applies to engine number 00185 and later. Screw M6 x 10 (ref. 2) appears in quantity 9 across multiple variants, while screw M6 x 16 (ref. 3) gets a K compatibility mark. If you skip that detail, you’ll order the wrong hardware and the pump housing won’t seal. The Crankshaft and Camshaft figures (11 and 12) are equally precise, with separate part numbers for each journal size variation.

Why a 108-Page OEM Catalog Beats a Third-Party PDF

Aftermarket parts catalogs often compress multiple engine variants into one generic drawing. This Kubota document separates the V3800DI-T-E3B-TLTU-1 from other V3800 series engines with distinct part numbers for items like the oil pan (Fig. 2), gear case (Fig. 8), and flywheel (Fig. 13). The compatibility codes (N, R, K, etc.) tell you exactly which revision supersedes which—something no reprint will guarantee. As a tech, I’d rather spend 30 seconds checking the correct part number here than an hour chasing a wrong-thread bolt because the aftermarket drawing used a generic M10x1.25 when the spec is M10x1.5.

Frequently Asked Questions

Does this catalog include torque specs for the cylinder head bolts?

No. This is a parts catalog, not a service manual. It lists part numbers and quantities, not torque values or assembly procedures. For torque specs you need the corresponding Kubota workshop manual for the V3800DI-T-E3B-TLTU-1.

Can I use this catalog to rebuild my injection pump?

Only if you are ordering replacement components. The exploded drawings show every seal, spring, and plunger in the pump assembly. However, the catalog does not provide disassembly steps or calibration data. Use it to identify the exact parts you need, then order from Kubota. For pump rebuilding you’ll need the service manual with adjustment specs.
