Kubota P-TB210R-AEXA Common Problems This Manual Covers
Hard starting or no-crank
A weak starter, failed solenoid, or worn starter components leave the engine cranking slowly or not at all. The Starter section gives the exploded view and part numbers to identify and order the right replacements.
Manual Section: Starter p. 54Rough running from fuel contamination
Water and dirt collecting in the fuel filter cause rough running and stalling until the element is replaced. The Fuel Filter section identifies the filter and related parts by reference number.
Manual Section: Fuel Filter p. 44Smoke or hard starting from injector wear
Worn nozzles and glow plugs show up as smoke, misfire, and cold-start trouble. The Nozzle Holder And Glow Plug section lists the nozzle holder, glow plug, and adjustment washer parts.
Manual Section: Nozzle Holder And Glow Plug p. 38Overheating under load
A clogged or damaged radiator restricts cooling and lets the engine overheat when worked hard. The Radiator section provides the exploded view and part numbers for the core and its fittings.
Manual Section: Radiator p. 64Coolant leaks or weak coolant flow
A failing water pump leaks or moves too little coolant, driving temperatures up. The Water Pump section identifies the pump assembly and its seals and gaskets by reference number.
Manual Section: Water Pump p. 62Charging faults or dead battery
A worn alternator or pulley leaves the battery undercharged. The Alternator And Pulley section lists the alternator, pulley, and mounting hardware so you order the correct parts.
Manual Section: Alternator And Pulley p. 50Low oil pressure
A worn oil pump or its relief components can drop oil pressure and risk engine damage. The Oil Pump section provides the exploded view and part numbers for the pump assembly.
Manual Section: Oil Pump p. 18Frequently Asked Questions
