HST whining under load or stalling on a grade? This catalog breaks down every seal, O-ring, and pump component by B7100HST-E serial number so you order right the first time.

This Kubota B7100HST-E Parts Catalog (OEM #100K0317) exists to do one thing: match the exact component to your tractor and serial number. Its 167 pages split into 83 pages of parts lists, 40 pages of engine breakdowns covering the crankcase, piston/crankshaft assembly, cylinder head, valve/rocker arm, nozzle holder, and injection pump, and 63 pages of drivetrain parts running from the HST unit through the rear differential and axle shafts. Hydraulic coverage fills 18 pages of diagrams and component parts: gear pump, control valve internals, lift arm, and pipe routing. Weights are spelled out too, with the complete crankshaft at 8 kgf and the STD piston at 0.304 kgf. Your serial range (B7100HST-E >=20025) is flagged on every applicable diagram, so you order the right part instead of a close guess. System bookmarks let you jump to a section and read the part number in seconds.

Kubota B7100HST-E Common Problems This Manual Covers

Kubota B7100HST-E HST internal component parts unclear for rebuild, uncertain which seals match my serial number range p. 96

Open the HST Component Parts exploded view on pages 96-98; every internal sub-assembly is broken out by item number. Confirm your serial number is B7100HST-E >=20025 before ordering, then check the interchangeability guidance, which flags parts listed as new-for-old, old-for-new, or not interchangeable.

Manual Section: HST [Component Parts]
Hydraulic gear pump O-rings and internal seal part numbers needed after disassembly, items don't match exploded view p. 56

Locate the Hydraulic Gear Pump Component Parts diagram on pages 56-57; each seal, O-ring, and body component is itemized by position number there. Cross-reference with the pump assembly overview on page 54 to confirm your pump body configuration. This section applies to serial numbers B7100HST-E >=20025.

Manual Section: Hydraulic Gear Pump [Component Parts]
Fuel shutoff solenoid, fuse, or relay part number needed to chase no-start electrical fault, correct items unknown p. 38

Find the Panel diagram on page 80 for fuse and relay part numbers. For the fuel shutoff solenoid, check the Injection Pump Component Parts on pages 38-39; the solenoid is broken out there by item number. The starter assembly weighs 4.7 kgf; its electrical components are on pages 72-74.

Manual Section: Injection Pump [Component Parts]
Oil pressure warning light stays on after startup, need part number for the pressure switch or sender p. 80

Check the Panel diagram on page 80 for warning light components and instrument sender item numbers. The oil pressure switch is part of the panel and electrical assembly covered there. Verify your tractor is in the B7100HST-E >=20025 serial range before cross-referencing substitutions.

Manual Section: Panel
Transmission or hydraulic housing dripping oil at fittings, O-ring and copper washer part numbers unknown p. 143

Pull the Hydraulic Pipe 1 diagram on pages 143-144 and Hydraulic Pipe 2 on pages 145-146; O-rings and copper washers are itemized by position there. For seals at the transmission case, check pages 88-89. Verify serial number is B7100HST-E >=20025; notes which O-rings are new-for-old substitutions.

Frequently Asked Questions

What are the replacement specifications for Hydraulic fluid strainer?

Hydraulic fluid strainers (filters) are listed by part number. The CARTRIDGE OIL FILTER is Part No. 66021-36060, and the JOINT FILTER is Part No. 66204-36170. Physical dimensions and other detailed specs for these parts aren't included.

What are the replacement specifications for O-rings?

O-rings carry their own part numbers rather than dimensions. From the hydraulic system you'll find Part No. 04811-00220 (O RING, page 144), Part No. 04811-00180 (O RING, page 146), and Part No. 04811-00120 (O RING, page 150). Material and dimensional specs for these O-rings aren't listed.

What format is this Kubota B7100HST-E manual in?

Delivered as a 167-page searchable PDF, downloadable the moment checkout clears. Open it on a laptop, tablet, or phone and carry it straight to the shop floor.

Am I able to print pages from this Kubota B7100HST-E manual?

Absolutely. There's no DRM or copy protection, so print the whole manual or just the pages you need. Any home or office printer handles it.

Can I find hydraulic circuit diagrams in this Kubota B7100HST-E manual?

This is a parts catalog, so it shows exploded parts diagrams rather than circuit schematics. It includes detailed exploded views of the hydraulic components — pump, control valve, cylinder, and oil lines — with OEM part numbers, not wiring-style circuit diagrams.

Document Quality

This document is a scanned PDF with an optical character recognition (OCR) layer, allowing you to search and copy all text. The text throughout is crisp and easy to read, with no blurry or faded sections. Diagrams and illustrations are raster images (scanned drawings or photos) that are generally clear, and their labels are readable. Pages are mostly clean, though you may notice minor scan artifacts like small specks or faint borders on some pages. There is one filler page (page 167) explicitly stating "IMAGE NOT AVAILABLE" where a diagram would typically be.
