  Erika NielsenAug 21, 2025
  If you notice black or dark gray exhaust gas from your wsm Tractor, it could be due to several reasons. You might be overloading the engine, so try reducing the load. It could also be caused by using low-grade fuel, so switch to the specified fuel. A clogged fuel filter or air cleaner could also be the culprit; in this case, replace the fuel filter or clean/replace the air cleaner. Finally, deficient injection may be the reason, so repair or replace the injector.

  If your wsm Tractor engine is overheating, several factors could be responsible. First, check the engine oil and coolant levels and replenish if insufficient. Inspect the fan belt for breakage or elongation and replace or adjust as necessary. Clean any dust from the radiator net and fins. If the inside of the radiator or coolant flow route is corroded, clean or replace the affected parts. A defective radiator cap should be replaced. Reduce the load if you are overload running. Replace the head gasket if defective, and ensure you are using the specified fuel.

  If your wsm Tractor's engine revolution isn't smooth, it could be due to a clogged or dirty fuel filter (replace it) or a clogged air cleaner (clean or replace it). A fuel leak due to a loose injection pipe retaining nut could also be the cause; tighten the retaining nut. Other potential causes include a malfunctioning supply pump (repair or replace it), a stuck or clogged injector (replace it), or a worn or bent turbocharger. If the turbocharger is faulty, replace the turbocharger assembly.

  If your wsm Tractor is showing deficient output, it might be because the engine’s moving parts seem to be seizing (repair or replace them), the supply pump is malfunctioning (repair or replace it), or there is deficient injection (replace the injector). Other possible causes include a compression leak (check the compression and repair), a gas leak from the exhaust system (repair or replace), an air leak from the compressor discharge side (repair or replace), a dirty or clogged air cleaner (clean or replace), or a compressor wheel that does not turn freely (replace the turbocharger assembly).

What to do if wsm M108S Tractor has low oil pressure?
- J
  Joshua OsborneSep 1, 2025
  If your wsm Tractor has low oil pressure, it could be due to several reasons: the engine oil level may be insufficient, so replenish it. The oil strainer might be clogged, so clean it. A relief valve could be stuck with foreign matter, so clean it, or the relief valve spring might be weak or broken, so replace it. Other causes include excessive oil clearance of the crankshaft bearing, crankpin bearing, or rocker arm, all of which would require replacement. Additionally, the oil passage could be clogged (clean it), you might be using a different type of oil (use the specified type), or the oil pump could be defective (replace it).
