Your Kubota BH75 backhoe parts catalog pdf runs 63 pages of OEM exploded views, part numbers, and interchangeability keys across every assembly on the machine. There are 29 numbered parts lists paired with labeled diagrams, plus 5 hydraulic hose routing sections for intake, swing, boom/dipper, bucket, and stabilizer. Component-level breakdowns cover all five cylinders (swing, boom, dipper, bucket, and stabilizer), and the hydraulic parts diagrams trace fluid paths through the complete control valve circuit. Mount kit sections confirm exact fitment across three tractor platforms: D21 for B2630/B3030, E27 for L2800/L3400, and D20 for B7800. No more ordering the wrong part and losing a week waiting to find out. Everything is bookmarked by assembly and searchable by keyword, so any diagram opens in seconds on whatever device is next to the bench.

Kubota BH75 Common Problems This Manual Covers
Kubota BH75 boom cylinder leaking or failing to hold position, need correct seal kit part number p. 37
Open the Cylinder(Boom) [Component Parts] exploded view on page 37. Locate the seal kit entry in the parts list on page 38 and record the exact part number. Cross-reference the seal kit against your machine's serial number to confirm fitment before ordering; cylinder bore diameter determines which kit applies.
Manual Section: Cylinder(Boom) [Component Parts]Hydraulic hose failed or leaking at boom or dipperstick connection, need replacement hose part number p. 29
Jump to the Hydraulic Hose(Boom/Dipper) section starting on page 29. The exploded diagram shows each hose by position and port. Match your failed hose to the diagram by routing and connection end type, then pull the part number from the list on page 30. Hose length and fitting thread size are encoded in the part number, so order exact rather than a generic cut-to-length.
Manual Section: Hydraulic Hose(Boom/Dipper)Swing cylinder seals worn, cylinder drifting or weeping oil at rod end p. 35
Inspect the Cylinder(Swing) [Component Parts] diagram on page 35. The parts list on page 36 breaks down rod seals, piston seals, and O-rings as individual line items or as a kit. Note whether your serial number falls in the range listed at the top of the section before ordering; Kubota revised seal specs across production runs.
Manual Section: Cylinder(Swing) [Component Parts]Control valve internal parts needed after debris contamination, can't identify individual spool components p. 22
Turn to the Control Valve [Component Parts] section on page 22. Pages 22 through 24 break the valve body down to individual spools, O-rings, springs, and retaining hardware. Find the affected spool position in the exploded view, then pull part numbers from the adjacent list. Order each seal and O-ring individually; no universal kit covers the full valve assembly.
Manual Section: Control Valve [Component Parts]Stabilizer cylinder seals blown, arm won't hold up under load, need all internal seal part numbers p. 43
Consult the Cylinder(Stabilizer) [Component Parts] section on page 43, which runs through page 46. It covers both stabilizer cylinders with full seal breakdowns including rod wiper, rod seal, piston seal, and backup rings as separate parts. Verify left versus right cylinder designation in the diagram before ordering; they are not always interchangeable.
Manual Section: Cylinder(Stabilizer) [Component Parts]Control lever feels sloppy or pivot hardware worn, need linkage and hardware part numbers p. 51
Compare Control Lever 1 on page 51 with Control Lever 2 on page 53. Both sections show the lever assembly exploded with pivot pins, bushings, clevis hardware, and return springs called out by part number. Identify which lever has the wear, match the pivot pin and bushing to the diagram, and order by part number; generic hardware will not match Kubota's bore tolerances on the pivot points.
Manual Section: Control Lever 1Frequently Asked Questions
What are the replacement specifications for hydraulic seals?
On the CYLINDER(BOOM) [COMPONENT PARTS], the KIT SEAL (Part No. 7K501-22300) carries a replacement spec of 65*35. Match that dimension when you order so the seal seats correctly.
What do I get after purchasing this Kubota BH75 manual?

Is this Kubota BH75 Parts Catalog printable?
Yes. With no DRM restrictions, you can print any page or section for the shop on any standard printer.
Are hydraulic system diagrams in this Kubota BH75 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.
Document Quality
This document is a scanned PDF with an OCR layer, allowing you to search and copy text throughout. The text is generally clear and readable, though it exhibits slight fuzziness typical of scanned documents. Diagrams and illustrations are raster images; their labels are readable, but the images themselves are not sharp at high zoom levels. All pages are clean and free of scan artifacts, stains, or skewed content. There are no notable blank or filler pages present in the document.
