To change the derby cover on a Harley-Davidson motorcycle, you will need some basic tools and follow these general steps:
Gather the necessary tools: You will typically need a wrench or socket set, a torque wrench, and a new derby cover.
Preparation: Ensure that your motorcycle is parked on a level surface and the engine is cool to the touch.
Locate the derby cover: The derby cover is usually located on the primary cover, which is on the left side of the motorcycle's engine. It covers the primary drive components.
Remove the derby cover screws: Use a wrench or socket set to loosen and remove the screws holding the derby cover in place. Depending on the model, there might be three or five screws.
Remove the old derby cover: Gently lift the derby cover away from the primary cover, being mindful of any gasket or seal that might be present. Carefully set aside the old derby cover and inspect the gasket for damage. If the gasket is worn or damaged, it's advisable to replace it with a new one.
Clean the surface: Before installing the new derby cover, clean the mating surface of the primary cover to ensure a good seal. Remove any debris, oil, or remnants of the old gasket.
Install the new derby cover: Place the new derby cover over the primary cover, aligning the screw holes. If necessary, apply a small amount of gasket sealant or lubricant to the new gasket to help with installation.
Attach the derby cover screws: Insert and tighten the derby cover screws by hand to ensure they are properly aligned. Then, use a torque wrench to tighten the screws according to the manufacturer's specifications. Be careful not to overtighten, as this could damage the cover or gasket.
Final check: Double-check that the derby cover is securely fastened and the screws are properly tightened. Clean any fingerprints or smudges off the derby cover with a clean cloth.
It's important to consult your motorcycle's owner's manual or refer to specific instructions for your model as there may be slight variations in the process. Additionally, if you're unsure or uncomfortable performing the task yourself, it's always recommended to seek assistance from a qualified mechanic or Harley-Davidson dealer.
