The fork of a motorcycle connects the main frame with the front wheel and axle. Thanks to this, motorcyclists can change direction. This also helps the proper functioning of the brake system and suspension. It is made up of two tubes. Each tube has a seal that keeps the oil inside the tube and prevents leaks. It should be replaced as soon as it begins to leak oil. If the seal is not changed, oil can drip onto the brake pedal and ruin the motorcycle. Also, if the motorcycle runs out of oil, it can be ruined. Follow these steps to learn how to replace a fork retainer.
Step 1. Prepare the motorcycle for maintenance
- Loosen the two bolts that secure the fork legs to the frame and the caps on each leg. Next, loosen the bolts on the brake caliper and the entire front axle of the motorcycle.
- Put the motorcycle in gear and chock the rear wheel.
- Raise the front wheel off the ground as much as necessary.
- Remove the brake calipers, fender, front wheel, and any other dangling cables.
Step 2. Remove the fork
- Loosen the bolts a bit more and pull the fork down as you turn.
- Remove the fork cap carefully. Be careful because the fork has a spring. Please don't get near the lid when you take it off.
- Remove the spring and let the oil drain into a bucket.
- Use a tool to reach up to the shock bar and release it.
- Memorize the suspension spring assembly, washers, and spacers to make it easier to reinstall.
Step 3. Remove the old retainer
- Shim the shock onto the fork leg.
- Find the fork retainer. It is held in a groove with a clamp.
- Observe the check carefully.
- Rinse the area to remove debris from inside the fork.
- Hold the tube with one hand and the stud with the other. Use force to separate them. You'll see the catch come off as you do it.
Step 4. Prepare the fork to fit the new retainer
- It removes all the rust and repairs the imperfections that caused the old seal to leak.
- Soak a rag in oil and clean the area where the seal was.
Step 5. Install the new retainer
- Rub the inside of the new seal with oil.
- Position the retainer on top of the stud and slide it to install it in the correct place.
- Attach the retainer with a seal conductor. This way, you can apply the sealer carefully and it will be firm.
Step 6. Put the hairpin in place
- Place the caliper and shock onto the fork. Install the damper rod.
- Pour the oil into the new fork and measure the level.
- Reinstall the spring and fork cap bolts. Tighten the screws.
Step 7. Repeat the process with the other fork leg
Step 8. Reassemble the front of the motorcycle
- Replace both seals at the same time, it doesn't matter if only one needs to be changed. In this way, the seals will have the same wear.
- Instead of using force to separate the inner tube from the fork and remove the seal, you can fill the tube with oil and press to break the seal.
- The safest way to lift the motorcycle for maintenance is to use a lift.
- You may need to replace the bar if you can't fix the old retainer damage.
