Description
5.9L Cummins common rail injector cleaning and testing services. The customer ships us their injectors for this service. We can usually test the units within 24-48 hours after we have received them.
We sonic wash the exterior of the injectors and inspect for obvious dirt, water, and metal contamination. We perform a solenoid resistance test & continuity/blockage test. The injector is then mounted to the test stand for additional solenoid testing, nozzle leak down test, fuel return, full load, light load, part load, and pilot injection fuel delivery. A printout of the test results is provided to the customer showing each test result including fuel delivery quantities and pass/fail indicators.
Failure Analysis:
If an injector does fail, with the customers approval, we can open their failed injector and perform a failure analysis with a digital microscope. Injectors often fail due to water, dirt, or metal contamination from the CP3 injection pump's gear pump. This is valuable information to prevent cross contamination with replacement injector units.
