Kubota BH65 Common Problems This Manual Covers
Weak or slow backhoe operation
After hookup the backhoe can move weakly or slowly when hydraulic oil is low or the circuit is air-bound. The hydraulic system group identifies the intake and function hoses that carry oil through the attachment.
Manual Section: Hydraulic System p. 35Leaking or worn hydraulic cylinders
Boom, dipper, bucket, swing, and stabilizer cylinders lose seal and start weeping with use. The hydraulic cylinder group breaks each cylinder into its component parts so you can order the right seals and pieces.
Manual Section: Hydraulic Cylinder p. 43Worn boom and dipper pins and bushings
The pins, inner rings, and bushings in the boom and dipperstick linkage wear and develop play over time. The front attachments group lists these parts with their dimensions for replacement.
Manual Section: Front Attachments p. 7Erratic or unresponsive controls
Sticky or erratic function response can come from wear inside the control valve spool sections. The control valve group breaks down each spool section into its component parts.
Manual Section: Control Valve p. 20Loose or worn control levers
Vague or loose control feel often traces to worn parts in the control lever assemblies. The control lever group identifies the lever components you need to restore precise operation.
Manual Section: Control Lever p. 57Difficult mounting or worn mount hardware
The BH65 can be awkward to attach when the mount kit hardware is worn or the machine is not level. The option group lists the mount kit and its parts for the hookup.
