Part of the Kubota Parts Manuals.
This is the Kubota parts catalog for the B1700E, B2100E, and B2400E compact diesel tractors, a 242 page illustrated parts book. It covers the machine assembly by assembly: the engine, clutch, transmission and rear axle, front axle and steering, the hydraulic pump, control valve and 3-point hydraulics, cooling, fuel, and the electrical system.Every section is an exploded diagram tied to Kubota part numbers, quantities, and serial number ranges, with country codes flagging parts that differ by market, so you can confirm the right component for your serial number before ordering.Use it to source filters, seals, gaskets, bearings, and hydraulic or driveline parts, and to see how each subassembly goes back together during service. Delivered as a downloadable, printable PDF for the shop or the field.

Kubota B1700E, B2100E, B2400E Common Problems This Manual Covers
Slow or weak hydraulic lift
A 3-point hitch that lifts slowly or lacks power often traces to a worn hydraulic pump or internal leakage. The Hydraulic Pump section breaks the pump down for parts identification.
Manual Section: Hydraulic Pump p. 663-point hitch drifts down
A hitch that slowly drops when parked usually means worn lift cylinder seals or a leaking control valve. The Hydraulic Cylinder Case section shows the lift cylinder components.
Manual Section: Hydraulic Cylinder Case p. 197Soft or uneven brakes
Brake pedals that feel soft or uneven need adjustment or rebuild as friction parts wear. The Brake section identifies the brake assembly components.
Manual Section: Brake p. 150Weak power steering
Power steering that gets heavy at idle but improves with engine RPM often points to the steering controller or hydraulic supply. The Steering Controller section breaks down its parts.
Manual Section: Steering Controller p. 180Hard starting
Hard starting is commonly tied to the battery, glow plug circuit, and connections on these small diesels. The Battery section covers the battery and related electrical parts.
Manual Section: Battery p. 100Overheating under load
A clogged radiator or weak cooling leads to overheating during heavy work. Use the Radiator section to source the radiator and cooling components.
Manual Section: Radiator p. 94Frequently Asked Questions
