Part of the Kubota Parts Manuals.
This is the factory parts catalog for the Kubota B7100HST-E compact diesel tractor, the new type edition covering B7100HST-D from serial 60164 and B7100HST-E from serial 20025. It is a 167 page PDF you download and keep, built from Kubota's own exploded diagrams and part number tables.Every assembly on the machine is here, from the crankcase, cylinder head and injection pump through the hydrostatic transmission, hydraulic gear pump, clutch, radiator and oil cooler, starter and electrical parts. Each diagram pairs numbered callouts with the matching part numbers, quantities and serial ranges.Because parts on the B7100HST split across old and new style serial ranges, matching the right diagram to your serial number saves real frustration. Use this catalog to service the HST, cure a hydraulic or electrical fault, or replace wear items, and print only the pages you need at the bench.

Kubota B7100HST-E Common Problems This Manual Covers
HST whines and weakens under load
The hydrostatic drive can whine loudly and lose power when pushing material or climbing grades. The HST section breaks down the transmission unit so you can identify worn internal parts and seals.
Manual Section: HST p. 94Oil pressure warning light stays on
A warning light that stays on after startup points to the oil pressure switch, wiring or gauge. The Panel section identifies the instrument panel parts and switches involved.
Manual Section: Panel p. 80No start with a good battery
No crank or no fuel delivery often traces to a fuse, relay, fuel shutoff solenoid or key switch. The Starter section shows the starter and related electrical components for diagnosis and replacement.
Manual Section: Starter p. 72Slow or noisy hydraulics
Weak or noisy hydraulic and steering response comes from a worn gear pump, clogged supply or leaking seals. The Hydraulic Gear Pump section details the pump body, gears and O rings.
Manual Section: Hydraulic Gear Pump p. 54Cooling and oil cooler problems
Overheating on the hydrostatic B7100 can involve both the radiator and the oil cooler. The Radiator/Oil Cooler section identifies the core, cap and mounting parts by part number.
Manual Section: Radiator/Oil Cooler p. 70Clutch drag or engagement issues
Worn clutch parts cause dragging or hard engagement. The Clutch section lays out the disc, cover and release components so you order the correct replacements.
Manual Section: Clutch p. 52Frequently Asked Questions
Which serial numbers does this catalog cover?
It is the new type catalog, publication 100K0317, for B7100HST-D from serial 60164 and B7100HST-E from serial 20025. Parts list by Kubota part number with serial ranges so you match your machine.
Does it include torque specs and repair steps?
This is a parts catalog, so it provides exploded diagrams, part numbers and component weights rather than repair procedures or torque tables. It is made for identifying and ordering the right parts.
Where do I find the hydrostatic transmission parts?
The HST section breaks down the hydrostatic transmission and its component parts, which is where to start when the drive whines or weakens under load. p. 94
Can I identify hydraulic gear pump parts?
Yes. The Hydraulic Gear Pump section separates the pump into body, gears, seals and O rings so you can order what slow or noisy hydraulics need. p. 54
What format is this 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 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.
