As a technical advisor for Ming Diamond, I have received countless inquiries from overseas buyers regarding the installation of the shock absorber for electric trolleys. Many repair shop owners and logistics fleet managers have told me that improper installation not only fails to utilize the performance of the shock absorber but also shortens its service life. Today, I will share a detailed step-by-step installation guide, along with key maintenance tips, to help you successfully replace the front and rear shock absorbers of the electric trolley. Whether you are a professional technician or a novice, this article will be of practical value to you.
Preparations before installing the shock absorber for the electric tricycle
Sufficient preparation is the prerequisite for a successful installation. Operating without having the necessary tools or without confirming compatibility can easily lead to installation failure and even damage the shock absorber. Here are the two most important preparation steps:
Essential Tools and Safety Precautions
First, let's sort out the necessary tools. To install the shock absorber for the electric tricycle, you need to prepare a set of socket wrenches (preferably including different sizes), a torque wrench, a jack, a support frame, and anti-rust lubricants. Among them, the torque wrench is particularly important - it can help you control the tightening force of the bolts, avoiding over-tightening or under-tightening. Regarding safety precautions, please remember to park the electric tricycle on a flat and solid surface first, turn off the power, and use the support frame to firmly fix the tricycle to prevent it from tipping over during the installation process. Additionally, it is recommended to wear gloves to protect your hands and avoid being scratched by metal parts.
Confirm the compatibility of the front and rear shock absorbers
Before installation, it is essential to ensure that the new shock absorber is compatible with your electric tricycle. Many buyers make mistakes at this stage - they purchase shock absorbers that do not match the model of their vehicle, resulting in waste of time and money. How to confirm compatibility? First, check the specifications of the original vehicle's shock absorber, such as the installation hole spacing, the stroke length of the shock absorber, the load-bearing capacity, etc.; second, if you are unsure, you can provide the brand and model of the electric tricycle to the Ming Diamond team. Our professional technicians will help you confirm the matching front and rear electric tricycle shock absorbers. It should be noted that the specifications of the front and rear shock absorbers of most cargo electric tricycles are different. Do not confuse them when replacing.
Step-by-step installation process
Next comes the core installation process. Let's take the replacement of the shock absorber as an example (the installation method for the front shock absorber is similar). Just follow the steps below to proceed:
Remove the old shock absorber
1. Use a jack to lift the rear part of the electric tricycle, then place a support frame under the frame to ensure the stability of the tricycle. Do not rely solely on the jack to avoid the risk of falling; 2. Use a socket wrench to loosen the bolts at both ends of the old shock absorber. If the bolts are rusty and difficult to loosen, spray some anti-rust lubricant and wait for 5-10 minutes before attempting again; 3. After loosening all the bolts, carefully remove the old shock absorber. Pay attention to the position of the connection part during the process, and take photos for reference if necessary, which will facilitate the installation of the new shock absorber.
Install the new shock absorber for the electric tricycle
1. First, inspect the new shock absorber - remove the protective film on the surface and confirm that the connecting parts are in good condition;
2. Align the new shock absorber with the installation position on the three-wheeler frame and axle, and temporarily fix it with bolts. At this time, pay attention to the direction of the shock absorber - usually the end with the rubber sleeve faces the frame, and the end with the piston rod faces the axle (for specific details, you can refer to the installation direction of the old shock absorber or the product manual provided by Ming Diamond);
3. Tighten the bolts one by one with a socket wrench, and then recheck the torque with a torque wrench. The recommended torque for most shock absorber bolts of electric three-wheelers is 35-45 Newton-meters, but it is best to refer to the maintenance manual of the three-wheeler;
4. After installing one side, repeat the above steps to install the other side of the shock absorber. If installing the shock absorber before, the operation process is basically the same, but be careful to protect the front fork and steering system of the three-wheeler.
Post-installation testing
After installing the new shock absorbers, do not rush to use the tricycle. You need to conduct a simple test first. First, remove the jack and the support frame, allowing the tricycle to land normally. Push the tricycle forward and backward to check if the shock absorber is flexible in movement and if there are any abnormal noises. Then, sit on the tricycle and press up and down on the body to feel the rebound of the shock absorber - if the rebound is smooth without any jamming, it indicates a successful installation. If you find abnormal noises or the movement is not flexible, you need to promptly check if the bolts are tightened properly or if the installation direction is incorrect.
Maintenance techniques for extending the replacement cycle
Proper maintenance can significantly extend the service life of the shock absorbers of electric tricycles and reduce the frequency of replacements. Here are three key maintenance tips summarized by Ming Diamond based on its years of after-sales experience:
Regular cleaning and inspection
It is recommended to clean the shock absorber once every 1-2 months. Use a clean cloth to wipe off the dust, dirt and other debris on the surface of the shock absorber. At the same time, check for any oil leakage (if there is oil stain on the surface of the shock absorber, it may be due to oil leakage). Check if the rubber sleeve is cracked and if the bolts are loose. If any of these problems are found, they need to be dealt with promptly - for example, tighten the loose bolts, replace the cracked rubber sleeve, and if there is oil leakage, contact our after-sales team for repair.
Avoid driving when overloaded or on bad road conditions.
Overloading is one of the main reasons for the premature failure of shock absorbers. When using a three-wheeled vehicle, do not exceed the load capacity of the shock absorber. Additionally, try to avoid driving on bumpy roads. If you must pass through such roads, reduce the speed to minimize the impact on the shock absorber. For users of cargo electric three-wheelers, this is particularly important - proper loading and smooth driving can effectively extend the service life of the shock absorber.
