What happens when cam follower fails?
Like any component, the cam follower will eventually wear. Causes of failure can range from using low-quality motor oil to making improper modifications to the fuel pump. If the cam follower wears all the way, damage to the cam shaft and fuel pump will probably follow.
How do you know if you have a bad cam follower?
There are a few different signs that could indicate that your vehicle’s cam follower has worn down: Check engine light. Runnability issues. Loud or low-pitched ticking sounds.
How often should I change my cam follower?
I don’t know anyone who replaces the cam follower every 5000-10000 miles- that’s crazy-no way they are wearing down that fast, even on the original version. My original was replaced at 40,000 miles, and didn’t show excessive wear (but replaced anyway). Based on what I saw, I’m going to replace every 30-40,000 miles.

What was the problem with the Caterpillar CAT C7 engine?
The ACERT Technology had a lot of problems for Caterpillar, first with the CAT C7 but more so later on with the CAT 13 and CAT 15 engines. The technology was really the first generation emissions technology for heavy duty diesel engines. The ACERT technology was prone to numerous regeneration issues. Drivers reported low power and low fuel economy.
What is the fuel delivery system on a cat C7?
The fuel delivery system on the CAT C7 is hydraulic electronically controlled unit injectors for the mid horsepower models and mechanically actuated and electronically controlled on the higher horsepower models. Both systems are metered and timed to inject multiple bursts of fuel to create a more efficient combustion cycle.
What’s the life expectancy of a cat C7 engine?
B10 is the average life expectancy of an engine measured in miles where 10% of the produced engines failed and needed a major overhaul. Consequently, B50 is the average miles where 50% of the engines failed. With the CAT C7 the B50 rating of 450,000-500,000 miles.
What kind of valve actuation does cat C7 use?
Within the design of the C7, the turbos use variable geometry valve actuation controlled by the ECM to adjust the perfect amount of airflow into the combustion chamber. This variable valve actuation also allows for the CAT C7 to offer an integral jake brake on two of the heavy duty diesel horsepower models.
