A cam dwell plate is a component that helps regulate the timing and operation of the engine’s camshaft.

It consists of a highly wear-resistance copper alloy whose sliding surfaces are evenly provided with a certain percentage of solid lubricant plugs according to work conditions, high-strength copper alloy provides a high load-bearing capacity, and the solid lubricant can be the formation of low friction film.

Under technical dry running conditions, the bearing surface is designed with a thick running-in film which enables the solid lubricant to be transferred to the counter material at the first contact.

How Does a Cam Dwell Plate Work?

An overrun cam made of bronze with a solid lubricant works by reducing friction and wear between two moving parts. The solid lubricant, usually graphite or molybdenum disulfide, is embedded within the bronze material and acts as a self-lubricating agent.

When the cam is in motion, the solid lubricant is released onto the surface of the cam, reducing friction and allowing for smoother motion. This helps to prevent damage to both the cam and the component it interacts with.

The bronze material used in the construction of the cam is also beneficial as it is durable and corrosion-resistant. This ensures that the cam will last for an extended period of time without needing to be replaced.

Maintenance Of Cam Dwell Plate And Overrun Cam

The cam dwell plate and overrun cam are both critical components in automatic transmissions. They work together to ensure that the transmission shifts smoothly and efficiently. However, like all mechanical components, they can wear out over time.

Proper maintenance is essential to ensure that the cam dwell plate and overrun cam function correctly. Regular fluid changes, filter replacements, and inspections can help identify any potential issues before they become major problems.

Why is the Cam Dwell Plate Important?

The cam dwell plate is an important component in the ignition system of an internal combustion engine. Its main function is to provide a fixed point of contact between the distributor cam and the ignition points, which in turn controls the timing of the spark that ignites the fuel in the engine’s cylinders.

The cam dwell plate helps to ensure that the ignition timing of an internal combustion engine remains consistent by providing a fixed point of contact between the cam and the points. which is crucial for efficient and reliable engine operation.

How To Test The Cam Dwell Plate

To test the cam dwell plate, you will need a dwell meter, which is a specialized tool that measures the amount of time the ignition coil charges before firing. Here are the steps to test the cam dwell plate:

  • Connect the dwell meter to the distributor.
  • Start the engine and let it idle.
  • Check the dwell reading on the meter.
  • Compare the reading to the manufacturer’s specifications.
  • If the reading is outside of the specified range, the cam dwell plate may be faulty.

The Role of the Overrun Cam

The overrun cam is another critical component in automatic transmissions. It is a small metal cam that is attached to the output shaft of the transmission. The overrun cam’s primary function is to prevent the transmission from shifting into reverse while the vehicle is moving forward.

When the vehicle is moving forward, the overrun cam is engaged. This prevents the transmission from shifting into reverse, which could cause severe damage to the transmission. If the driver attempts to shift into reverse while the vehicle is moving forward, the overrun cam will prevent the transmission from engaging the reverse gear.

Differences Between Overrun Cam And Cam Dwell Plate

difference in Function

An overrun cam is used to maintain engine timing during deceleration, while a cam dwell plate is used to control valve timing during engine operation.


cam works by rotating the camshaft slightly during deceleration, which allows the engine to maintain optimal combustion and reduce emissions. A cam dwell plate, on the other hand, works by controlling the timing of the engine valves, which affects the engine’s power output and efficiency.


the overrun cam is typically a small, simple component that can be easily added to an engine’s timing system. A cam dwell plate is a more complex component that requires precision manufacturing and is designed specifically for use in engines.


Overrun cams are typically designed to work with specific engines or engine families, while cam dwell plates may be compatible with a wider range of engines and applications.
