A motorcycle shock spring compressor is used to compress the coil spring of shock absorbers. This makes it easier to remove or install the shocks. There are several types of motorcycle shock spring compressors, as discussed below:
Hydraulic Compressor
This type of compressor uses fluid power to compress spring coils. It has a tank with hydraulic fluid and a pump that generates pressure. The pressure and fluid's force allow the compressor's pistons to move and compress the springs.
Threaded Rod Compressor
A threaded rod compressor has one or two rods with threads. When the rods are turned, the springs either compress or expand. The turning is achieved using a spanner on the notches on the top of the spring.
Electric Compressor
An electric compressor gets its power from an electric motor. The motor drives the compressor blades to create airflow and pressure. It is much quicker than the manual compressors but at a higher price.
Clamshell Compressors
These compressors have two halves shaped like shells that enclose the spring. They are hinged at the back and have a locking mechanism at the front. The clamshell halves close and open like a clam, allowing for easy spring compression and release.
Impact Wrench Compressors
These compressors use an impact wrench to turn the compressor's drive shaft. The impact wrench applies high torque with its rotating hammering mechanism. This makes it easier to compress large or heavy springs.
Fork Spring Compressors
Fork spring compressors are designed to work on the springs found in the forks of the front wheel. Just like other types of springs, fork springs can become worn out and require replacement. The motorcycle will not run properly if the fork springs are not in good condition. Fork spring compressors have rods and clamps. They also have a handle that makes it easier to adjust and operate.
Before purchasing a motorcycle shock spring compressor, it’s important to understand its specifications. Here are some of them:
Load capacity
The load capacity of a motorcycle shock spring compressor is the total weight it can lift. This figure is important when working with heavy springs. The load capacity for most compressors is about 400-600 lbs.
Compressed length
The compressed length is the total length of the compressor when the springs are fully compressed. This measurement is important when storing the tool in tight spaces. The compressed length on most compressors is around 18-22 inches.
Extended length
The extended length of the motorcycle shock spring compressor is the total length when the springs are not compressed. This measurement is important when working with long or wide springs. The extended length for most compressors is about 28-32 inches.
Handle length
The handle length is the total length of the compressor handles. This measurement is important when applying force to tighten or loosen spring bolts. The handle length for most compressors is around 6-8 inches.
Thread size
The thread size on the compressor bolts must match the holes on the motorcycle shocks. Most compressor bolts come with a thread size of 1/4-20 or 3/8-16.
Motorcycle shock spring compressors don’t need a lot of maintenance. However, users should inspect and clean them regularly to ensure they last longer. Here are some maintenance tips:
Cleaning
After use, the compressor should be cleaned to remove dirt and debris. A soft bristle brush can be used to wipe the body, as well as the spring clamps. Doing this will prevent rust and ensure the machine works properly.
Inspection
Periodically, users should inspect the motorcycle shock spring compressor to check for any signs of damage. They should pay attention to the clamps and the body for worn-out parts. If any damage is found, the user should replace or repair the machine.
Lubrication
The clamps and the body of the motorcycle shock spring compressor have moving parts that require lubrication. Users should apply a few drops of oil at least once a month to ensure the clamps move smoothly.
Correct Usage
Users should always follow the manufacturer's instructions when using the motorcycle shock spring compressor. Doing this will prevent damage to the tool as well as the motorcycle shocks.
There are several factors to consider when choosing a motorcycle shock spring compressor for resale, including:
Brand reputation
When choosing a motorcycle shock spring compressor, consider the brand's reputation. Well-known brands have established a reputation for reliability and quality.
Quality and durability
Quality and durability are important factors to consider when choosing a motorcycle shock spring compressor. Always go for compressors with sturdy construction.
Price
Price is an important factor to consider when choosing a motorcycle shock spring compressor. Choose a compressor that is affordable without compromising quality.
Ease of use
Another factor to consider is the compressor's ease of use. Choose a compressor that is easy to use and understand, with clear instructions.
Portability
Portability is also an important factor to consider when choosing a motorcycle shock spring compressor. Choose a compressor that is portable and easy to carry.
Versatility
Consider the compressor's versatility before choosing a motorcycle shock spring compressor. Choose a compressor that is compatible with different spring sizes and types.
Safety features
Always consider the safety features of a motorcycle shock spring compressor. Choose a compressor with safety features such as safety locks and protective covers.
Warranty
Consider the warranty when choosing a motorcycle shock spring compressor. Choose a compressor with a good warranty period to protect your investment.
Customer reviews
Finally, consider customer reviews before choosing a motorcycle shock spring compressor. Read customer reviews to learn about the experiences of other users.
Replacing shock springs can be very dangerous if not done properly. The spring carries a lot of tension, and if it is released suddenly, it can cause serious injuries. Before attempting to replace a shock spring, ensure that one has the right training. Only a qualified technician should replace a shock spring. If an owner decides to do it themselves, make sure to follow the manufacturer's instructions carefully.
To replace a motorcycle shock spring, first remove the shock absorber from the motorcycle. After that, use a shock spring compressor to safely remove the old spring and install the new one. Then, refit the shock absorber and make sure it is working properly.
Here is a detailed guide on how to replace a motorcycle shock spring:
Prepare the bike
Ensure the bike is on a flat surface. Use a paddock stand to hold the bike in place and to prevent it from falling over.
Remove the shock absorber
Remove the nuts at the top and bottom of the shock absorber using a ratchet and socket. Then, pull the shock absorber out of the mounting points.
Compress the spring
Use a motorcycle shock spring compressor to compress the spring. Place the compressor at both ends of the spring and tighten it until the coils are firmly touching each other.
Remove the spring
Once the spring is fully compressed, remove the top and bottom retainers. Then, remove the spring from the shock absorber body.
Install the new spring
Place the new spring over the shock absorber body. Then, fit the retainers and use the compressor to compress the spring until it fits perfectly. Make sure to follow the manufacturer's recommendations.
Reinstall the shock absorber
Once the new spring is fitted, reinstall the shock absorber and tighten the nuts securely.
Q1: What is a motorcycle shock spring compressor?
A1: It is a tool that helps increase or decrease the tension of a shock spring on a motorcycle.
Q2: How does a motorcycle shock spring compressor work?
A2: The compressor works by using its mechanical advantage to push the coils of a spring together. This makes the spring's diameter smaller, allowing it to fit within the shock absorber.
Q3: Can beginners use shock spring compressors?
A3: Yes, but they must read the manufacturer's instructions and, if necessary, seek the advice of a professional mechanic.
