If you are an avid cyclist, you know how important it is to keep your bike in top condition. One crucial part of maintaining your bike is taking care of the fork seals, especially if you have an SR Suntour XCM fork. Over time, these seals can wear out or get damaged, which can lead to oil leakage and reduced performance. In this article, we will guide you through the process of changing the SR Suntour XCM fork seals, so you can get back to enjoying a smooth and reliable ride.
Before we begin, it is important to note that changing fork seals requires some technical know-how and the right tools. If you are not comfortable working on your bike or do not have the necessary tools, we recommend taking your bike to a professional bike shop for assistance.
Firstly, start by removing the front wheel and disconnecting the brake caliper from the fork. Next, loosen the fork crown bolts and carefully remove the fork from the bike. Place the fork in a bike stand or hold it securely using a workbench vice.
Once the fork is secured, use a 5mm Allen key to remove the top caps from both sides of the fork. With the top caps removed, you will be able to access the fork seals. Gently pull the old seals out using a small pick or flathead screwdriver, taking care not to damage the fork tubes. Clean any dirt or debris from the fork tubes and inspect them for any signs of damage.
Now it’s time to install the new fork seals. Apply a thin layer of fork oil or suspension grease to the new seals and carefully slide them onto the fork tubes. Make sure the seals are properly seated and aligned before proceeding. Once the new seals are in place, reinsert the top caps and tighten them with the 5mm Allen key.
Finally, reinstall the fork onto your bike, making sure it is properly aligned and tightened. Reconnect the brake caliper and install the front wheel. Check the fork for any signs of oil leakage and test its performance by compressing and rebounding the fork a few times. If everything looks and feels good, you’re all set!
By following these steps and taking care of your SR Suntour XCM fork seals, you can ensure that your bike performs at its best and provides you with a smooth riding experience.

Overview of SR Suntour XCM Fork Seals
The SR Suntour XCM fork is a popular choice among mountain bike enthusiasts due to its durability and performance. However, over time, the fork seals may start to wear out, leading to oil leaks and decreased suspension performance. To maintain the fork’s optimal performance, it is essential to regularly inspect and replace the fork seals.
SR Suntour XCM fork seals are responsible for keeping the fork’s oil contained within the stanchions, preventing dirt and debris from entering and affecting the fork’s performance. When the seals start to wear out, it can lead to oil leakage, reduced suspension response, and potential damage to the internals of the fork.
Replacing the fork seals is a relatively straightforward process that requires a few basic tools and some mechanical know-how. Here are the general steps involved in changing the fork seals on an SR Suntour XCM fork:
- Start by removing the front wheel from the bike and loosening the brake caliper to allow for fork removal.
- Next, remove the top cap and loosen the bolts on the crown of the fork to separate the upper and lower legs.
- Once the upper and lower legs are separated, carefully remove the old fork seals using a seal pick or a small flathead screwdriver. Be careful not to scratch or damage the stanchions during this process.
- After removing the old seals, clean the stanchions thoroughly to remove any dirt or debris.
- Apply a small amount of fork oil to the new seals and carefully slide them onto the stanchions, making sure they are properly seated.
- Reassemble the fork by tightening the bolts on the crown, installing the top cap, and reattaching the brake caliper.
- Finally, test the fork’s suspension to ensure it is functioning correctly. If there are any issues, double-check the seal installation and make any necessary adjustments.
Regular maintenance and seal replacement will keep your SR Suntour XCM fork performing at its best and extend its lifespan. Remember to consult the manufacturer’s guidelines for specific instructions and recommended seal replacement intervals.
