Recognizing the signs that your oil pump is about to fail is essential for a fleet manager and a driver. Not only is it frustrating when components fail, but it’s also a potential safety and hazard risk. Once you know the signs of a possible failure, it makes it that much easier to prevent it from happening. Or, your drivers will have the time to take their trucks in for repairs immediately when things go wrong.
Here are some signs of semi-truck oil pump failure:
Low Oil Pressure Warning Lights
A warning light will be your first and most obvious sign of something wrong with the oil pump. The oil pump regulates the oil pressure, so when the pressure decreases, the light goes on. If it’s simply low oil, try filling it up and check again. If the pressure is still low even after that, it’s an issue with the oil pump. Likely, you’ll need to get the pump replaced before anything worsens.
A Red Hot Engine
Oil in the engine acts as both a lubricant and a cooling method for the moving parts. Without the right amount of oil, the engine can easily overheat and risk dangerous trouble. Once the engine overheats, it starts causing damage to itself and the components, which can easily wrack up thousands in repairs. A warning light will signal when the engine gets too hot, so don’t ignore that warning for your semi-truck oil pump.
While driving, are you noticing a lot of noise or whirring and whining sounds? It may even happen while the vehicle is idle. If yes, it’s one of two issues.
One of the components in a vehicle is the valve-train which keeps the engine running. Those parts can seize and stop working when there isn’t enough oil flow. You notice then when low oil levels coincide with noisy sounds from the engine. While rare, the oil pump’s internal gears are totally worn out if it’s a whirring or whining sound. In that case, it’ll need a complete replacement as soon as possible to avoid oil pump failure.
Root Causes of Semi-Truck Oil Pump Failure
Poor installations and poor maintenance are the leading causes of most issues with heavy truck oil pumps. With an oil pump, when it’s installed improperly, it risks several issues. First, part of the pump housing can bend and cause issues. In cases where there is a gap, it can create a buildup that makes a difference in the thickness of the oil pump. Finally, the poor installation also leads to a lack of proper lubrication, which leads to premature wear and, eventually, oil pump failure.
Improper maintenance also results in contaminants lingering, causing premature wear or parts failing and going unnoticed.
