What to do if my Kubota M108S Tractor starter does not run?
If the starter on your Kubota Tractor isn't running, it could be due to a discharged battery (charge or replace), a malfunctioning starter (repair or replace), a malfunctioning key switch (replace), or disconnected wiring (connect).
Why is my Kubota M108S Tractor engine not starting?
Several factors can prevent your Kubota Tractor engine from starting. It could be due to no fuel, which means you should replenish the fuel. Alternatively, there might be air or water in the fuel system, requiring you to vent the air or drain the water. Other potential causes include a malfunctioning electric fuel feed pump (replace it), a clogged fuel hose (clean or replace it), or a clogged fuel filter (replace it). The issue might also stem from excessively high viscosity of fuel or engine oil at low temperature, in which case you should use the specified fuel or engine oil. Using fuel with a low cetane number also can cause this problem, so use the specified fuel. Other causes could be: fuel leak due to loose injection pipe retaining nut (tighten retaining nut); injector clogged (repla...
Why is my Kubota Tractor engine difficult to start?
Several factors can cause a Kubota Tractor engine to be difficult to start. It could be due to no fuel flow, so check the fuel tank and fuel filter, replacing the filter if needed. Air or water in the fuel system could also be the problem; ensure the fuel line coupler bolt and nut are tight. In cold weather, the oil viscosity may increase, slowing the engine revolution; use oils with different viscosities depending on ambient temperatures and consider using an engine block heater. A weak battery can also prevent the engine from turning over quickly enough; clean the battery cables and terminals, charge the battery, and in cold weather, remove the battery, charge it, and store it indoors until use. Lastly, there could be an issue with the intake air heater system; check the slow blow fuse a...
What to do if water mixed into engine oil in my Kubota M108S?
If water is mixed into the engine oil in your Kubota Tractor, it could be due to a defective head gasket (replace) or a flawed cylinder block or cylinder head (replace).
What to do if fuel mixed into engine oil in my Kubota M108S Tractor?
If fuel is mixed into the engine oil of your Kubota Tractor, it could be due to deficient injection (replace injector) or a fuel leak from the overflow pipe inside of cylinder head cover (replace the gasket).
What causes oil leak into exhaust pipe or suction pipe in Kubota M108S Tractor?
Oil leaking into the exhaust pipe or suction pipe of your Kubota Tractor could be due to a waste oil pipe clogged or deformed (repair or replace) or a faulty turbocharger’s piston ring seal (replace the turbocharger assembly).
What causes high oil pressure in my Kubota M108S?
High oil pressure in your Kubota Tractor could be due to using a different type of oil (use specified oil) or a defective relief valve (replace).
What to do if my Kubota M108S has low oil pressure?
If your Kubota Tractor is experiencing low oil pressure, it could be due to several reasons: insufficient engine oil (replenish), a clogged oil strainer (clean), a relief valve stuck with foreign matter (clean), or a relief valve spring that is weak or broken (replace). Other potential causes include excessive oil clearance of the crankshaft bearing (replace), excessive oil clearance of the crankpin bearing (replace), excessive oil clearance of the rocker arm (replace), a clogged oil passage (clean), using a different type of oil (use specified type of oil), or a defective oil pump (replace).
What does it mean if my Kubota M108S has either white or blue exhaust gas?
If your Kubota Tractor is emitting white or blue exhaust gas, it could indicate excessive engine oil (reduce to specified level) or worn or stuck piston ring and cylinder (repair or replace).
What to do if my Kubota M108S Tractor engine overheats?
If your Kubota Tractor engine overheats, several issues could be the cause. First, the engine might be overloaded, so shift to a lower gear or reduce the load. Check the coolant level and fill the cooling system to the correct level, inspecting the radiator and hoses for leaks. A loose or defective fan belt can also cause overheating, so adjust or replace it. Make sure the radiator core or grille screens are free of debris. Finally, the coolant flow route may be corroded, requiring you to flush the cooling system.
