Kubota B26 Common Problems This Manual Covers
Engine cranks but will not start
A B26 that cranks but will not fire often has a faulty fuel stop solenoid or its wiring rather than a fuel pump. The Stop Solenoid section shows the solenoid and its parts with numbers to order.
Manual Section: Stop Solenoid p. 70Rough running or power loss
Loss of power and rough running frequently trace to a clogged air cleaner element restricting airflow. The Air Cleaner section identifies the element and housing parts for replacement.
Manual Section: Air Cleaner p. 47Weak or slow hydraulics
Weak or slow hydraulics can come from a worn pump or relief components. The Hydraulic Pump section gives the pump breakdown and part numbers.
Manual Section: Hydraulic Pump p. 156Overheating during work
Overheating on the B26 usually means a blocked or damaged radiator or its hoses. The Radiator section lists the radiator, cap and related parts.
Manual Section: Radiator p. 66Hard cold starting
Hard cold starts point to worn glow plugs or nozzle holders. The Nozzle Holder and Glow Plug section shows these parts with their numbers.
Manual Section: Nozzle Holder and Glow Plug p. 34Drive feels weak or creeps poorly
Sluggish drive or poor creep speed is often an HST wear issue. The HST section and its component-parts diagrams identify the hydrostatic transmission parts to replace.
Manual Section: HST p. 109Frequently Asked Questions
