1. Can I replace the series 50 water pump myself?
Yes, the water pump can be replaced as long as you have the required tools and knowledge to do that. There are a few steps; you need to drain the coolant, remove the pump, and replace the new pump.
Don’t forget to also replace the water pump gasket.
If you encounter any difficulty, you can consult the Detroit Diesel series 50 service manual.
2. What causes noise from the water pump?
Certain things could cause the water pump to make noise, such as worn bearings, cavitation caused by low coolant, and a damaged pump gear.
3. What are the most common symptoms of a failing alternator?
a. Inability to charge the battery, which causes weak or dead batteries.
b. Noise from the alternator, such as a whining noise.
c. Unstable voltage reading
d. Dimming headlights
e. Battery warning light on the dashboard coming up.
4. Can the alternator be rebuilt?
Yes, the alternator can be rebuilt. You don’t have to replace the alternator always; rather, you can replace the brushes, voltage regulator, bearings, and rectifier.
5. How long does the head gasket last?
The head gasket could last up to 300,000 to 500,000 miles if there is proper maintenance and if you can avoid overheating, which usually causes damage to the gasket.
6. How to prevent head gasket failure?
These are some measures that can help you prevent the head gasket from being damaged;
a. Ensure the correct torque spec is used.
b. Ensure the engine temperature is normal
c. Ensure there is the right coolant level in the radiator.
7. How many piston rings does the series 50 have per piston?
The engine has 3 piston rings per piston.
The first piston rings are called compression rings, the second ring assists the compression ring and the oil ring, and the last ring is called the oil ring, which controls the oil that lubricates the cylinder walls.
8. How to prolong the lifespan of the crankshaft bearings?
The bearing’s lifespan could be prolonged by using high-quality oil, ensuring you replace the oil filter, avoiding over-revving the engine, and ensuring the correct torque spec is used when tightening the bearings bolts.
10. When should the crankshaft bearings be replaced?
The bearings should be replaced during the engine rebuild, and should be inspected constantly. The inspection is necessary when the engine engages in long haulage.
