Part of the Kubota Parts Manuals.
Every assembly on your B1700D, B2100D, or B2400D compact tractor mapped to its factory part number across 261 pages. Exploded views cover 125 parts-list assemblies, with hydraulic breakdowns of the pump, control valve, steering controller, and flow divider, plus drivetrain diagrams from clutch shaft through rear differential and front axle case. Crankcase, oil pan, cylinder head, injection pump, governor, nozzle holder, dynamo, starter, panel board, transmission case, brake, ROPS, and wheel options from 6-12 fronts to 31x15.5-15 rears are all here. Need a +0.50mm oversize piston or the -0.40mm undersize crankpin metal? Reference numbers are right there. Panel board diagrams sit alongside the 30A main fuse and 5A auto fuse callouts. Stop ordering the wrong bushing twice. Bookmarked by system: tap the assembly, read the Ref.No, order the right part the first time.

Kubota B1700D, B2100D, B2400D Common Problems This Manual Covers
Rear brake disc and lining part numbers hard to identify when ordering a replacement set
Open the Brake exploded view on page 151. Match your serial number range to the brake disc and lining callouts, then cross-reference the parts number list. Order discs and linings as a matched set per side, and verify the 30A main fuse circuit on page 113 is unrelated before assuming a parts mismatch.
Manual Section: Brake p. 151Front axle bevel gear and shim part numbers unclear when rebuilding a 4WD case with backlash issues
Pull the Bevel Gear Case diagram on page 175 and the Front Axle Case view on page 177. Identify the bevel gear set, bearings, and shim pack by callout number. Confirm the 11-20T front differential bevel gear teeth count on page 174 matches your assembly before ordering shims and bearings as a kit.
Manual Section: Bevel Gear Case p. 175Hydraulic pump component parts and seal kit numbers confusing when sourcing rebuild parts for a weak lift
Reference the Hydraulic Pump Component Parts exploded view on page 68. Identify the pump body, gears, and seal callouts, then list each part number from the parts list. Check the suction line components on pages 203 to 206, since a clogged suction screen often masks as a pump parts problem.
Manual Section: Hydraulic Pump [Component Parts] p. 683-point hitch lift rod, lower link, and top link parts missing or mismatched on a used tractor
Work from the Lift Rod view on page 222, Lower Link on page 224, and Top Link on page 226 to identify each pin, bushing, and link by callout. Verify Category 1 hitch dimensions against your implement before ordering. Review the Control Valve component parts on page 218 if drift symptoms accompany missing hardware.
Manual Section: Lift Rod p. 222Fuel filter element and bowl assembly part numbers unclear when ordering a replacement for hard starting
Pull up the Fuel Filter Component Parts diagram on pages 88 to 89. Identify the filter element, bowl, O-ring, and bracket by callout number. Cross-reference the Fuel Pipe layout on page 84 to confirm inlet and outlet fitting sizes match before ordering, since suffix variants between B1700D, B2100D, and B2400D differ.
Manual Section: Fuel Filter [Component Parts] p. 88Starter relay kit and glow plug part numbers hard to find when diagnosing cold-start failures
Compare the Starter Relay Kit option diagram on page 260 against the Nozzle Holder and Glow Plug section on page 39. Identify the relay, harness, and glow plug callouts. Verify against the Battery layout on page 100 and confirm the 30A main fuse on page 113 matches your panel before ordering the relay kit.
Manual Section: Stater Relay Kit [Option] p. 260Frequently Asked Questions
What are the replacement specifications for fuel filter?
The complete fuel filter assembly is part number 15751-43010. The replaceable element inside is part number 15231-43560. p. 89
What are the replacement specifications for air filter?
For serial numbers up to 50558, the air filter element is part 67980-82630. From serial 50559 and up, it changes to 6A100-82630. The optional double air cleaner uses outer element 6C040-94240 with inner element 6C040-94250. p. 72
