Part of the Kubota Parts Manuals.
Every part number in this Kubota B7100HST-D Parts Catalog (OEM #11052) ties back to an OEM diagram, so you can match the piece in your hand before calling the counter. The 43 pages of indexed parts lists run through every system on the tractor: crankcase, cylinder head, hydrostatic transmission, control valve, and 3-point linkage. Exploded views separate the piston and crankshaft assembly, differential, bevel gear case, front axle arm, and knuckle arm down to the individual item number. Serial number callouts (S.No. <=60163) flag which superseded parts fit your specific machine rather than a generic guess. One wrong digit on an order means a week's wait and a part that doesn't fit. Bookmarked by system and keyword-searchable, it opens on your phone right in the shop: find the number, place the order, get back to the job.

Kubota B7100HST-D Common Problems This Manual Covers
Kubota B7100HST-D control valve O-rings and seal part numbers needed, hydraulic fluid leaking from control area p. 82
Open the Control Valve exploded view on page 82. Locate each O-ring and seal by item number in the parts list. The complete ASSY VALVE,CONTROL assembly weighs 2.665 kgf (5.863 lb) per page 83. Use that to confirm you have the right assembly listed before ordering individual seals. Cross-reference part numbers against your serial number range to verify catalog coverage.
Manual Section: Control ValveOld-type vs new-type serial number split causes confusion, wrong parts arrive that won't fit p. 125
Verify your tractor's serial number before ordering any front axle or drivetrain parts. The old-type sections start at page 125 and cover S.No. <=60163 for the B7100HST-D. Tractors above those numbers use entirely different part numbers, so match your S.No. to the correct diagram section first. One wrong digit brings a part that won't fit.
Manual Section: Front Axle Arm [Dp] Old TypeFuel shutoff solenoid and electrical component part numbers needed, tractor cranks but won't start p. 119
Check the Panel parts diagram on page 119 for fuse and relay part numbers. Fuses listed there weigh 0.004 kgf each, confirmed on page 120. Locate the fuel shutoff solenoid in the Injection Pump section starting at page 30, and verify your serial number (S.No. <=60163) matches the catalog before ordering any electrical components.
Manual Section: PanelHydrostatic transmission internal parts identification needed after teardown, tractor won't move p. 80
Pull up the Hydro Static Transmission exploded view on page 80 and identify each internal component by item number. The oil filter assembly weighs 0.367 kgf (0.8074 lb) on page 81, so verify your replacement matches that spec. Match the part numbers to the parts index to confirm serial number compatibility before you order.
Manual Section: Hydro Static TransmissionOil pressure pipe fitting O-rings and copper washers part numbers needed, hydraulic oil seeping at line connections p. 78
Turn to the Oil Pressure Pipe diagram on page 78. Locate each fitting, O-ring, and sealing washer by item number in the parts list. Cross-reference with Oil Pressure 1 on page 84 and Oil Pressure 2 on page 86 to identify all sealing components across the circuit. Confirm your serial number S.No. <=60163 matches catalog coverage before ordering.
Manual Section: Oil Pressure Pipe3-point linkage component part numbers needed for old-type serial number range, ordered parts won't fit p. 139
Start with the 3-Point Linkage diagram on page 139, which covers old-type tractors with S.No. <=60163 (B7100HST-D) only. The complete linkage assembly weighs 28 kgf (61.6 lb) on page 140; use that figure to confirm you are on the right assembly diagram. Identify each pin, bracket, and lift arm by item number before ordering, since new-type serial numbers use a separate parts section.
Manual Section: 3-Point Linkage [Ep,Dp] Old TypeFrequently Asked Questions
How do I bleed fuel or reset after fuel filter replacement on a Kubota B7100HST-D?
The manual gives no step-by-step bleeding procedure, but it does list a "SCREW,AIR BREEDER" (Part No. 15331-51350), quantity 1, in the INJECTION PUMP section. That screw is the fitting normally used to bleed air from the fuel system.
What format is this manual in?
A 146-page Parts Catalog in searchable PDF, ready to download the moment checkout completes. Open it on a computer, tablet, or phone, with no shipping wait.
Can I print this manual?
Yes. The PDF carries no DRM, so you can print any page or section you need for the shop on any standard printer.
Are hydraulic system diagrams in this Kubota B7100HST-D Parts Catalog?
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.
