Anyone who has worked on their own mountain bike suspension knows that removing fork wiper seals can be a challenging task. Wiper seals are an essential component of the fork, as they help keep dirt, water, and debris out of the fork’s internal components, ensuring smooth operation and prolonging the life of the suspension.
However, over time, wiper seals can wear out or become contaminated, leading to decreased performance and potential damage to the fork. When this happens, it is important to know how to remove the old wiper seals and replace them with new ones.
To remove fork wiper seals, you will need a few tools: a small flathead screwdriver, a pick set, a seal puller, and a clean cloth. First, start by taking off the front wheel and loosening the lower pinch bolts to allow the fork legs to separate.
Next, use the small flathead screwdriver to gently pry up the edge of the wiper seal, being careful not to damage the fork or the seal itself. Once the edge is lifted, use the pick set or the seal puller to carefully pull the seal out of the fork leg. If necessary, use a clean cloth to wipe away any dirt or debris that may have accumulated in the fork leg.
With the old wiper seal removed, you can now proceed to install the new seal. Make sure to apply a small amount of suspension oil to the new seal and carefully slide it into place, pressing it down evenly until it is fully seated. Once the new seal is in place, reassemble the fork legs, making sure to tighten the lower pinch bolts and reinstall the front wheel.
Removing fork wiper seals can be a delicate and time-consuming process, but with the right tools and a little patience, it can be done. By regularly inspecting and replacing your fork wiper seals, you can ensure the longevity and optimal performance of your mountain bike suspension.
