Maintaining your Shimano PD-6800[paid link] pedals is essential to ensuring smooth, efficient cycling performance over time. Regular maintenance helps extend the lifespan of the pedals, optimize power transfer, and prevent issues such as engagement problems or stiffness. This guide will take you through the necessary steps to maintain your PD-6800[paid link] pedals, ensuring they perform at their best for years to come.

Regular Cleaning and Inspection

One of the most critical aspects of pedal maintenance is keeping them clean. Dirt, mud, and water can build up on the pedal body and in the mechanism, potentially leading to stiffness or malfunction. Here’s how to clean and inspect your PD-6800 pedals:

• Remove the Pedals: Use a pedal wrench[paid link] to remove your pedals from the crankset. It’s important to note that the right pedal is threaded clockwise, and the left pedal is threaded counterclockwise.
• Clean the Pedal Bodies: Use a soft brush and mild soap solution to clean the pedal bodies. Avoid using harsh chemicals or abrasive materials that could damage the finish.
• Inspect for Wear: While cleaning, carefully inspect the pedal bodies, spindle, and engagement mechanism for signs of excessive wear or damage. Look for any cracks, deep scratches, or rust. Pay attention to the condition of the spring tension, as it can wear out over time.

Lubrication of Pedal Spindles

Proper lubrication is crucial to ensuring the smooth rotation of the pedal spindles. Over time, the grease inside the pedal can wear out or become dirty, affecting pedal smoothness. Here’s how to keep the spindles in top shape:

• Remove Pedal Spindle: To access the spindle, you’ll need to disassemble the pedal. This can be done using a proper tool, like a 10mm Allen wrench[paid link]. Be careful not to damage the spindle or any seals.
• Clean and Re-grease: Once the spindle is removed, clean it with a rag and reapply high-quality grease to the spindle and internal bearings. Use a grease that is designed for bike components to ensure longevity and smoothness.
• Reassemble the Pedal: Carefully reassemble the pedal after greasing the spindle. Make sure all parts fit together properly, and ensure the internal bearings are not damaged.

Spring Tension Adjustment

The PD-6800 pedals use a spring mechanism to control the engagement and release tension. Over time, you may need to adjust the spring tension for optimal performance. Here’s how to adjust it:

• Locate the Tension Adjustment: The spring tension adjustment screw is located on the outer edge of the pedal body. You’ll need a small screwdriver to make this adjustment.
• Adjust to Your Preference: Turning the screw clockwise will increase the tension, making it harder to release the shoe from the pedal. Turning it counterclockwise will reduce the tension, making it easier to unclip. Adjust the tension to match your preferred level of engagement, ensuring that you can easily clip in and out without sacrificing security.
• Test the Adjustment: After making adjustments, clip in and out of the pedal several times to ensure that the tension feels right. Fine-tune the setting if necessary.

Bearing Maintenance and Replacement

The bearings in the PD-6800 pedals play a crucial role in ensuring smooth pedal rotation. Over time, these bearings can wear out, resulting in a rough, stiff feel when pedaling. Here’s how to maintain or replace the bearings:

• Check for Bearing Play: Hold the pedal body and try to move it side to side. If you notice any lateral movement, it may indicate that the bearings need to be serviced or replaced.
• Service the Bearings: If the bearings are still in good condition, you can clean and re-grease them to restore smoothness. Use a bearing press[paid link] to remove and replace any worn-out bearings. Ensure you use bearings that are compatible with Shimano pedals.
• Replace Bearings if Necessary: If the bearings are worn beyond repair, replacing them is essential to avoid long-term damage to the pedal. Shimano PD-6800 pedal bearings are replaceable, and you can purchase new bearings directly from Shimano or an authorized dealer.

Pedal Spindle and Thread Maintenance

To ensure the best performance and prevent issues with pedal installation or removal, it is important to maintain the pedal threads:

• Inspect the Threads: Check both the pedal spindle and crankset for damage or wear. If the threads are worn, it may be difficult to install the pedals correctly, or they may not stay secure during rides.
• Lubricate the Threads: Apply a small amount of anti-seize grease to the threads before reinstalling the pedals. This helps to prevent the pedals from seizing onto the crank arms, which can make future removal difficult.
• Tighten Properly: Always tighten the pedals to the manufacturer’s torque specifications, typically 35-55 Nm, to avoid over-tightening, which can cause damage to the threads.

Regular Pedal Inspection

Even after performing the necessary maintenance, regular inspections are key to ensuring that your pedals continue to perform at their best. Each time you clean your bike or before long rides, check your PD-6800 pedals for the following:

• Loose Parts: Ensure that the pedal body and spindle are securely fastened.
• Engagement Performance: Ensure the pedal clips engage and release smoothly without excess friction or difficulty.
• Cracks or Damage: Inspect for any signs of cracks, especially around high-stress areas like the pedal body and spindle.

By following this maintenance plan, you can ensure that your Shimano PD-6800 pedals remain in excellent condition, allowing you to enjoy smoother rides and better performance over the long term. Regular attention to cleaning, lubrication, tension adjustment, and bearing maintenance will go a long way in extending the lifespan and optimizing the functionality of your pedals.
