Ohlins forks are renowned for their high performance and reliability, making them a popular choice among motorcycle enthusiasts. However, like any suspension component, they require regular maintenance and occasional rebuilds to ensure optimal performance.
Rebuilding Ohlins forks can be a daunting task, but with the right tools, knowledge, and patience, it is something that can be done at home. This guide will take you through the step-by-step process of rebuilding Ohlins forks, from disassembly to reassembly, providing helpful tips and precautions along the way.
Before diving into the rebuild process, it’s important to note that proper safety precautions should be taken. This includes wearing protective gear, such as gloves and goggles, and using a secure and level work area. Additionally, it’s recommended to have a service manual specific to your Ohlins fork model for reference.
The first step in rebuilding Ohlins forks is to completely disassemble them. This involves removing the fork caps, rebound adjusters, compression adjusters, and any other external components. It’s important to keep track of the order in which these components are removed, as they will need to be reassembled in the same order.
Once all the external components are removed, the next step is to remove the fork tubes from the lower legs. This may require the use of a special tool, such as a fork seal driver or a fork tube holder. Care should be taken not to damage the fork tubes or the lower legs during this process.
With the fork tubes removed, the next step is to disassemble the internals of the forks. This involves removing the damper rods, main springs, and any other internal components. It’s important to pay close attention to the order in which these components are removed, as they will need to be reassembled in the same order.
Once all the internal components are removed, it’s time to inspect and clean them. This includes checking for any signs of wear or damage, such as pitting or leaking oil. Any worn or damaged components should be replaced with new ones to ensure optimal performance.
After inspecting and cleaning the components, the next step is to reassemble the forks. This involves reinstalling the internal components, followed by the fork tubes. It’s important to follow the specific torque specifications for each component to ensure proper installation.
Once the forks are reassembled, the final step is to fill them with the appropriate amount and type of fork oil. This will vary depending on your specific Ohlins fork model and your riding preferences. It’s important to refer to your service manual for the correct specifications.
With the forks filled with oil, the last step is to reinstall the external components and properly adjust the rebound and compression settings. This will require referring to your service manual for the correct settings and procedures.
Rebuilding Ohlins forks is a labor-intensive process, but when done correctly, it can greatly improve the performance and lifespan of your suspension. By following these steps and taking your time, you can ensure that your Ohlins forks are operating at their best, providing you with a smoother and more controlled ride.
