Car Valve Spring Compressors: Choosing the Right Tool for the Job
There are two main types of valve spring compressors: coil-over compressors and C-clamp compressors. Each has its advantages and disadvantages, and choosing the right one for the job is essential.
Coil-over Compressors
Coil-over compressors consist of a pair of parallel bars with a spring-loaded handle at one end. The bars are placed over the valve spring, and the handle is used to compress the spring. These types of compressors are suitable for most valve springs and are often the go-to choice for mechanics. However, they can be difficult to use in tight spaces due to their size and shape.
C-clamp Compressors
C-clamp compressors consist of two C-clamps that are attached to the valve spring retainer. The clamps are then tightened to compress the spring. These compressors are more compact than coil-over compressors, making them easier to use in tight spaces. However, they are not as versatile and may not be suitable for all types of valve springs.
When choosing a valve spring compressor, it is crucial to consider the type of engine you will be working on and the space available for the tool. It is also essential to invest in a high-quality compressor that can withstand the pressure and tension of compressing valve springs.
A Comprehensive Guide to Valve Removal with Car Valve Spring Compressors
Now that we have discussed the different types of valve spring compressors let's take a closer look at the process of removing valves using a car valve spring compressor.
- Begin by disconnecting the battery and removing any spark plugs from the engine. This will prevent any accidental starts or sparks during the compression process.
- Next, remove the valve cover to gain access to the valves and valve springs. It is recommended to clean the area around the valves before proceeding further.
- Choose the correct sized compressor for the valve spring and place it over the spring, ensuring that the claws of the compressor are gripping the spring firmly.
- Use the handle or clamp of the compressor to gradually compress the spring until there is enough clearance to remove the keepers (clips that hold the spring in place).
- Once the keepers are removed, slowly release the pressure on the compressor, and the valve will come out with the spring and retainer.
- Before installing new valves, it is essential to check the compression and tension of the springs using a spring tester. This will ensure that the new springs are within the manufacturer's specifications.
- To install the new valve, place it on top of the spring and retainer, making sure it is aligned correctly.
- Use the compressor to compress the spring again and install the keepers.
- Slowly release the pressure on the compressor, and the valve will be securely in place.
- Repeat these steps for each valve, and once all valves have been replaced, reinstall the valve cover and spark plugs before reconnecting the battery.
Safety First: Essential Precautions for Using Car Valve Spring Compressors
Working with valve springs can be dangerous if proper safety precautions are not followed. Here are some essential safety tips to keep in mind when using a car valve spring compressor:
