Tools Required for Changing Derby Cover
Changing the derby cover on your Harley Davidson requires a few essential tools. Having the right equipment makes the task smoother and more efficient.
Essential Tools
- Socket Wrench Set: A socket wrench set helps you easily remove and tighten the bolts on the derby cover. Look for sizes that fit your model.
- Torque Wrench: A torque wrench ensures you apply the correct amount of force when fastening the bolts. This tool helps prevent damage to the cover.
- Gasket Scraper: A gasket scraper removes the old gasket material from the cover and engine. It’s crucial for a proper seal with the new cover.
- Rags: Rags keep the work area clean and help you wipe off any oil or debris from the components during the process.
- Oil Drain Pan: An oil drain pan catches any excess oil that may spill when you remove the derby cover.
- Impact Wrench: An impact wrench speeds up the removal of bolts but requires caution. This tool can be too powerful for some riders.
- Pliers: Pliers assist you in gripping and maneuvering small parts during installation, especially if they’re hard to reach.
- Light: A bright LED work light illuminates the area, making it easier to see what you’re doing, especially in tight spots or low-light situations.
- Safety Goggles: Safety goggles protect your eyes from debris and falling components as you work on your bike.
- Gloves: Gloves keep your hands clean and shield them from sharp edges or hot surfaces.
Gather these tools before you start changing the derby cover to make the process efficient and hassle-free.
Preparing Your Harley Davidson
Before changing the derby cover on your Harley Davidson, ensure your motorcycle is ready for the task. This preparation enhances safety and efficiency.
Safety Precautions
Wear your safety goggles and gloves. These protect you from debris and oil while working. Ensure you park the motorcycle on a flat surface, preferably with the engine off and cooled down. Always use a motorcycle stand for stability. If you’re working outdoors, consider covering the bike to keep dirt away.
Removing the Old Derby Cover
Start by draining the primary fluid to prevent spills. Use the oil drain pan positioned underneath. Locate the derby cover and remove the screws with your socket wrench. Keep the screws in a safe place for later use. Gently pull the cover away from the primary case. If it sticks, use a gasket scraper to separate it without damaging the surrounding area. Inspect the old gasket for wear—this indicates whether a replacement is necessary. Remove any leftover gasket material to ensure a proper seal when you install the new cover.
Installing the New Derby Cover
Installing the new derby cover involves a few straightforward steps. Follow these instructions to ensure a successful installation.
Applying Gasket Sealant
Applying gasket sealant creates a watertight seal. Use a thin, even layer of sealant on the edges of the new gasket. Be sure to select a high-quality, motorcycle-specific sealant to ensure durability. Press the gasket into place and allow it to set for a few minutes. This step is crucial to prevent leaks.
Securing the New Cover
Securing the new derby cover requires precision. Position the cover carefully over the gasket, aligning it with the mounting holes. Use the original screws to secure the cover. Tighten each screw in a crisscross pattern to ensure even pressure. Don’t overtighten, as this can damage the cover or gasket. Finally, double-check that all screws are snug and the cover is properly seated.
Common Mistakes to Avoid
When changing a derby cover on your Harley Davidson, avoiding common mistakes ensures a smooth and effective process.
Misalignment Issues
Misalignment occurs when the derby cover doesn’t sit evenly on the motor. This often leads to leaks and other complications. Always inspect the gasket alignment before securing the cover. Ensure the holes in the cover align perfectly with the holes on the motor. If they don’t match, loosen the screws slightly and adjust the cover until it fits correctly. Take extra care to avoid forcing the cover into place, which can damage both the cover and the motor.
Over-Tightening Bolts
Over-tightening bolts can cause serious damage to the cover and the motor. It’s essential to use a torque wrench to apply the manufacturer-recommended torque settings. Tighten the bolts in a crisscross pattern for even distribution. If you feel resistance, stop and check the alignment rather than applying unnecessary force. Remember, snug is enough; excessive tightness may strip threads or crack the cover.
Conclusion
Changing the derby cover on your Harley Davidson can be a rewarding experience. Not only does it enhance the look of your bike but it also ensures everything runs smoothly. By following the steps outlined and keeping an eye on those common pitfalls you can make the process seamless.
Remember to take your time and double-check your work. A little patience goes a long way in avoiding leaks and ensuring a perfect fit. With your new derby cover in place you can hit the road with confidence knowing you’ve done it right. Enjoy the ride and the satisfaction of a job well done!
