FAQ

Q: How do I confirm that the 3418533 injection follower will fit my engine?

A: The 3418533 is a standard part for the Cummins NT855 engine series. To confirm fitment, remove the existing injection follower from your engine and compare it visually and dimensionally with the replacement. The most reliable method is to check the part number stamped on your old component. If it reads 3418533, this part is the correct replacement. If you have a different number, please contact us for a cross-reference check.

Q: What are the common signs of a failing injection follower on a Cummins NT855?

A: A worn or damaged injection follower can cause several symptoms: a noticeable ticking or knocking sound from the valve cover area (especially at idle), rough engine running, loss of power, increased fuel consumption, and potential misfiring. In severe cases, a failed follower can damage the camshaft lobe and the injector itself. If you observe these symptoms, inspect the follower immediately.

Q: Should I replace the injection follower in pairs or individually?

A: While it is possible to replace a single failed follower, it is considered a best practice to replace all followers in the engine during a major overhaul or when the cylinder head is removed. For targeted repairs on an NT855, if you are replacing one due to failure, it is highly recommended to inspect and potentially replace the other followers on the same camshaft bank to ensure even wear patterns and future reliability. Always replace the associated injector push tube and inspect the camshaft lobe for damage.
