Every component on your B2100HSD, B1700HSD, or B2400HSD traces back to one of 140 illustrated parts lists here, from the crank case and injection pump to the HST, bi-speed turn system, front and rear axles, and three wheel size configurations. Exploded diagrams follow the full hydraulic oil circuit: suction, steering, T/M, the HST loop, and oil cooler routing, with control valve breakdowns down to individual seals and seats. Need the +0.50MM oversize piston or the 0.20MM injection pump shim for the B2100HSD? Part numbers sit beside each view, so there's no guessing and no flipping between three separate catalogs. Bookmarks group everything by system, and the text is fully searchable: open it on your phone at the parts counter and order what you need the first time.

Kubota B2100HSD, B1700HSD, B2400HSD Common Problems This Manual Covers
Need correct 30A main fuse part numbers for Kubota B2100HSD electrical wiring harnesses after a no-start condition. p. 117
Check the electrical wiring diagram on page 117. Locate the exact part number for the 30A main fuse or the 10A auto fuses. If you are operating a Canadian model, reference page 119 for the 50A fuse block components and wiring harness connections.
Manual Section: Electrical WiringLooking up correct oversize piston and undersize crankpin bearing part numbers after severe engine rod knock. p. 22
Cross-check the engine rotating assembly on page 22. The B2100HSD takes a +0.50MM oversize piston kit; pair it with the -0.20MM SET crankpin metal undersize bearings to hold correct clearances.
Manual Section: Piston and Crank ShaftNeed to order replacement bevel gears for the front axle after teeth shearing and binding. p. 199
Trace the front axle exploded diagram from page 199. On B2100HSD tractors the bevel gear assembly sits on page 201, where the 41T gear carries its own part number. Match the bearings and seals listed alongside to finish the order.
Manual Section: Front AxleSearching for exact replacement bulb and housing part numbers after the rear hazard lights shatter. p. 114
Pull up the lighting breakdown on page 114. For B2100HSD machines, the 27W bulb part number appears on page 115. Order the matching lens, housing, and wiring pigtail from the illustrated list to bring rear lights back.
Manual Section: Tail Light/Hazard Light/Working LightFrequently Asked Questions
What are the replacement specifications for fuses?

Document Quality
This is a scanned copy of a physical parts book that has been processed with OCR, so you can search the full text and copy part numbers. The text in the parts tables is clear and legible, while the exploded-view diagrams are raster images that become pixelated when zoomed in, though the callout numbers are still readable. The pages are mostly clean, with only a few minor scan artifacts and a slight skew on some pages; there are no major stains or handwritten marks.
