What causes damage to diesel injectors?
There are two major causes of diesel fuel injector failure associated with the properties of the fuel itself: excess wear and deposits. One mode of injector failure is excess wear. This sulfur comes from the crude oil refined into the fuel. This sulfur in the fuel acted as a natural lubricant for the fuel system.
What causes a diesel injector to crack?
The Cause and the Symptoms A cracked nozzle such as this will leak fuel into the engine cylinder any time the fuel system is pressurized. When there is a lack of fuel in the injector (or air in the system), the needle violently slams shut against its seat, which can quickly lead to the formation of cracks.
Are there any problems with Detroit Diesel Series 60 engines?
Changing the SRS (Synchronous Reference Sensor) and TRS (Timing Reference Sensor) could also help with this issue. These two sensors should be replaced at the same time to maintain proper operation. This particular issue affects Series 60 engines built before 2002.
Where is the fuel injector located on a Detroit Diesel engine?
The fuel injector rocker arm assembly is located between the intake and exhaust rocker arm assemblies and has a single bushing (not serviced separately). A rocker arm shaft carries three sets of rocker arm assemblies and is mounted in seats machined into the camshaft bearing caps.
What causes a series 60 engine to fail?
This separation allowed the connecting rod to disconnect as well, and one of the loose components would then damage the engine block, often by creating a hole through it. This issue did not affect all pre-2002 Series 60 engines, but it was a problem that occurred and could cause catastrophic engine failure.
Are there any problems with the Detroit Diesel 14L?
Another common complaint, especially with the 14L, is poor fuel economy. As the engine got bigger and was designed for more horsepower, fuel usage seemed to increase as well. Some argue that this lowering of fuel economy is not due to engine design, but to poor operating practices.
