Factory OEM parts data for the Kubota BH65 Backhoe Attachment fills all 76 pages here, with exploded views and part numbers across every major assembly. Coverage runs from the Main Frame and Swing Frame through the Front Attachments (Swing Cylinder, Boom, Dipperstick, Bucket, Stabilizer Arm), then into the Control Valve with spool breakdowns for Swing, Boom, Stabilizer, Dipperstick, and Bucket, plus component parts for all five Hydraulic Cylinders. Hose routing is mapped circuit by circuit: Intake, Swing, Boom/Dipper, Bucket, and Stabilizer. Specs come straight from the factory; the Swing Frame grease fitting runs 1/8-27NPT thread, and the Boom Pin measures 1.18*7.96 inches. Optional sections cover the Mount Kit, Seat Support, and Thumb Arm Kit, each with part numbers.

Kubota BH65 Common Problems This Manual Covers
Kubota BH65 hydraulic hose part number needed, old hose has no visible identification markings p. 35
Find the Hydraulic System exploded views starting on page 35. Each hose assembly is broken out by circuit: Intake, Swing, Boom/Dipper, Bucket, and Stabilizer. Locate your specific hose in the matching circuit diagram, note the part number, then cross-reference the parts list to confirm the correct fitting size and thread spec for your serial number range.
Manual Section: Hydraulic SystemMounting pins won't seat during attachment, need correct replacement pin dimensions and part number p. 7
Check the Front Attachments parts diagram starting on page 7. The standard swing cylinder connection pin measures 25*107 mm (page 8); verify that dimension matches what you're replacing before ordering. If it's the stabilizer arm pin, that one is 25.4*105 mm (page 18). Order by part number from the corresponding parts list.
Manual Section: Front AttachmentsBoom cylinder leaking, seal kit part number unclear on the exploded view diagram p. 43
Open the Hydraulic Cylinder section at page 43. Each cylinder (Swing, Boom, Dipper, Bucket, and Stabilizer) has its own component parts diagram listing every seal, O-ring, and wiper by part number. The swing cylinder head is 60*30 mm (page 44); match your cylinder before pulling seals to avoid ordering the wrong kit.
Manual Section: Hydraulic CylinderControl valve disassembled, cannot identify individual spool component part numbers for replacement order p. 21
Start in the Control Valve section at page 20. Each spool section, Swing, Boom, and Stabilizer, has its own component parts diagram on page 21. Find your specific spool by function, then pull the part number for each internal component. The complete valve assembly weighs 18.06 lbs; confirm the section before ordering individual spool parts.
Manual Section: Control ValveGrease fitting stripped on swing frame, need correct thread spec to source replacement fitting p. 5
Locate the correct fitting spec before ordering. Swing Frame grease fittings (page 5) use 1/8-27NPT thread; boom and dipperstick fittings (page 11) use 1/4-28T.T.*.68. Match the part number from the corresponding exploded view, not just the thread size. Kubota uses different fitting styles in adjacent locations on the same machine.
Manual Section: Swing FrameBucket tooth worn completely flat, need to identify correct bolt-on tooth part number p. 16
Pull up the Front Attachments section at page 7 for the bucket assembly diagram. Bolt-on tooth assemblies are listed with individual part numbers; each bolt-on tooth weighs 3.19 lbs (page 16), so confirm count before placing your order. Cross-reference the parts list to verify adapter compatibility if you're switching tooth profiles.
