Introduction
Do you suspect you have a flat tappet cam in your engine? It’s important to know what type of camshaft you have in order to ensure your engine is performing optimally. In this article, we’ll provide a comprehensive guide on how to tell if you have a flat tappet cam, including information on the components of a flat tappet cam, how to identify it, and how to troubleshoot common problems associated with this type of cam.
What is a Flat Tappet Cam?
A flat tappet cam is a type of camshaft that is typically used in older engines. A camshaft is an integral part of an engine, as it is responsible for controlling the intake and exhaust valves of the engine. The flat tappet cam is so named because it has a flat section on the camshaft lobe that works in conjunction with the lifters, or tappets, in the engine.
Components of a Flat Tappet Cam
The components of a flat tappet cam include the camshaft itself, the lifters, the pushrods, the rocker arms, and the valve springs. The camshaft is the main part of the system and is responsible for controlling the opening and closing of the intake and exhaust valves in the engine. The lifters are responsible for transmitting the motion of the camshaft to the rocker arms, which in turn open and close the valves. The pushrods transmit the motion from the lifters to the rocker arms, while the valve springs act as a cushion to prevent the valves from opening and closing too quickly.
How to Identify a Flat Tappet Cam
The easiest way to identify a flat tappet cam is by looking at the camshaft itself. The camshaft should have a flat section on the lobe, which is the area that interacts with the lifters in the engine. Additionally, if the engine has been disassembled, the lifters will be visibly flat as opposed to the rounded lifters used in roller cams.
Troubleshooting Common Problems with Flat Tappet Cams
Flat tappet cams are prone to wear and tear over time, and can cause a variety of engine problems if not properly maintained. Common problems associated with flat tappet cams include poor performance, valvetrain noise, and excessive oil consumption. If you suspect you have a flat tappet cam, it’s important to have it inspected and serviced by a qualified technician.
Frequently Asked Questions about Flat Tappet Cams
What are the symptoms of a worn flat tappet cam?
Common symptoms of a worn flat tappet cam include poor engine performance, valvetrain noise, and excessive oil consumption.
How often should a flat tappet cam be serviced?
Flat tappet cams should be serviced at least once a year in order to ensure optimal engine performance and longevity.
Can the camshaft lobe of a flat tappet cam be replaced?
Yes, the camshaft lobe of a flat tappet cam can be replaced if it is worn or damaged.
What is the difference between a flat tappet cam and a roller cam?
The main difference between a flat tappet cam and a roller cam is that a flat tappet cam uses flat lifters, while a roller cam uses rounded lifters. Additionally, flat tappet cams are typically found in older engines, while roller cams are more commonly found in newer engines.
Conclusion
In conclusion, it’s important to know if you have a flat tappet cam in your engine. Knowing how to identify and troubleshoot common problems associated with flat tappet cams can help ensure your engine is running optimally. If you have any further questions about flat tappet cams, be sure to consult a qualified technician.
