Understanding the Camshaft
A camshaft is a crucial component of an engine that plays a significant role in its performance. Understanding the camshaft and its function is essential for anyone involved in engine maintenance or performance tuning.
Definition and Function of a Camshaft
A camshaft is a cylindrical shaft that is responsible for controlling the opening and closing of the engine’s valves. It is typically located in the engine block and is driven by the crankshaft through a timing belt or chain. The camshaft has lobes or cams that push against the valves, causing them to open and close at specific intervals.
The main function of the camshaft is to regulate the intake and exhaust valves’ timing, ensuring efficient fuel combustion and optimal power output. It determines the engine’s overall performance characteristics, such as horsepower, torque, and fuel efficiency.
Different Types of Camshafts and Their Applications
There are various types of camshafts, each designed for specific applications and engine configurations. Here are some common types:
Stock Camshafts: These camshafts come as standard equipment in most production vehicles. They are designed for everyday driving and provide a balance between performance and fuel efficiency.
Performance Camshafts: Performance camshafts are designed to enhance engine performance by increasing valve lift and duration. They are commonly used in high-performance and racing engines to maximize power output.
Hydraulic Camshafts: Hydraulic camshafts use hydraulic lifters to reduce valve train noise and provide smoother operation. They are commonly found in passenger vehicles and offer a good balance between performance and comfort.
Solid Camshafts: Solid camshafts are used in high-performance engines that require precise valve control. They do not have hydraulic lifters and require regular adjustment to maintain proper valve clearance.
Roller Camshafts: Roller camshafts use roller lifters instead of flat lifters, reducing friction and improving valve train efficiency. They are commonly used in high-performance engines to enhance durability and performance.
The choice of camshaft depends on the engine’s intended use, desired performance characteristics, and other factors such as compression ratio, intake and exhaust system, and fuel type.
Understanding the different types of camshafts and their applications is crucial when selecting the right camshaft for an engine upgrade or replacement.
In conclusion, the camshaft is a vital component of an engine, responsible for controlling valve timing and optimizing engine performance. By understanding the different types of camshafts and their applications, engine enthusiasts can make informed decisions when it comes to enhancing their engine’s performance.

In order to accurately measure a camshaft, you will need a few essential tools. These tools are designed to help you gather precise measurements and ensure the proper functioning of the camshaft. Let’s take a look at the tools you will need and their purpose:
Micrometer or Dial Indicator
A micrometer or a dial indicator is one of the most important tools for camshaft measurement. It allows you to measure the dimensions of the camshaft lobes with great precision. The micrometer or dial indicator will help you determine the lift and duration of the camshaft lobes, which are crucial factors in engine performance.
Dial Indicator and Magnetic Base
A dial indicator is used to measure the runout of the camshaft. Runout refers to any deviation from a perfectly circular motion. It is important to check for runout as it can affect the performance and longevity of the camshaft. The dial indicator is attached to a magnetic base, which provides stability during the measurement process.
Degree Wheel
A degree wheel is used to evaluate the camshaft timing. It allows you to measure the exact position of the camshaft in relation to the crankshaft. This measurement is crucial for achieving optimal engine performance. The degree wheel is typically attached to the crankshaft, and the dial indicator is used to measure the movement of the camshaft.
Feeler Gauges
Feeler gauges are thin strips of metal that are used to measure clearances between different components. In the case of camshaft measurement, feeler gauges are used to check the clearance between the camshaft lobes and the valve lifters. This measurement ensures that the camshaft is properly aligned and functioning correctly.
Vernier Caliper
A vernier caliper is a precision measuring instrument used to measure the diameter of the camshaft journals. The camshaft journals are the cylindrical sections of the camshaft that rotate within the engine. It is important to measure the journal diameter to ensure proper fit and alignment within the engine.
Cleaning Supplies
In addition to the measurement tools mentioned above, you will also need cleaning supplies to ensure accurate measurements. Cleaning solvents or degreasers can be used to remove any dirt, debris, or oil from the camshaft before taking measurements. This will help you obtain precise and reliable results.
