Kubota L5240HST-C, L5740HST-C Mid-size Tractor Parts Manual

The Kubota L5240HST-C, L5740HST-C parts manual is for the mid-size cab HST tractors in that Grand L series—bigger than my BX, closer to my L3901 in “real work” territory. It’s what you grab when you’re staring at a leaking fitting, a worn 3-point pin, or a mystery seal and you want the right Kubota number before tearing things apart. Folks like me who’d rather order parts once and skip three trips to the dealer counter lean on this kind of book. The listing you’re looking at is a parts manual only, not a repair/WSM.

What this manual helps you do

• Identify every OEM part number on the tractor from exploded diagrams of engine, HST transmission case, front axle, hydraulics, PTO, and 3-point hitch.
• Locate where each hose, fitting, seal, and bracket actually sits on the machine so you don’t guess from a parts desk description.
• Look up the correct quantity of bolts, washers, o-rings, and gaskets before a teardown so you can order everything in one shot.
• Cross-reference older numbers to newer Kubota superseded numbers using the two included revisions (BKIDK0645, BKIDK0646).
• Verify that the part you’re about to order really matches your L5240HST-C or L5740HST-C layout, especially around options and sub-assemblies.

Who this is for

This fits an independent ag mechanic, a farm owner-operator who wrenches weekends, Kubota dealer parts staff, or anyone running a couple of orange tractors and trying to keep downtime low. If you’re after torque specs, hydraulic test procedures, or “how to” repair steps, you want the Workshop/Service Manual instead, not this parts catalog.

FAQ

Q: Does this cover the engine, hydraulics, HST transmission, PTO, and electrical?

A: Yes, parts manuals like this show exploded assemblies and part numbers for the engine, HST drivetrain, hydraulic circuits, PTO, 3-point, steering, and electrical components.

Q: Are the part numbers in this manual current?

A: It includes two revisions (BKIDK0645 and BKIDK0646), and Kubota uses those to note superseded numbers, but the dealer’s system is always the final word on the latest updates.

Bottom line: If you already know how to turn the wrenches and just need diagrams and Kubota numbers for an L5240HST-C or L5740HST-C, this is the right manual; if you need step‑by‑step repair instructions, keep looking for the WSM.
