The Shimano PD-5800 [paid link] pedals, part of the Shimano 105 series, offer a great balance of weight, efficiency, and durability for road cyclists. Proper installation and maintenance of these pedals ensure smooth engagement, long-lasting performance, and injury prevention. This guide will walk you through installing, adjusting, and maintaining your PD-5800 [paid link] pedals, covering everything from tension adjustment to bearing service and troubleshooting common issues.

Tools Required

To install, adjust, and maintain your PD-5800 [paid link] pedals, you’ll need the following tools:

  • 8mm Allen wrench [paid link] (for installation and removal)
  • Torque wrench [paid link] (for precise installation torque)
  • Grease (for pedal threads)
  • Flat-head screwdriver (for tension adjustment)
  • Needle-nose pliers (for bearing service, if needed)
  • Degreaser and clean cloth (for cleaning)
  • Shimano pedal maintenance grease (for lubrication)

Step 1: Installing the PD-5800 Pedals

Proper installation prevents premature wear and ensures efficient power transfer. Follow these steps:

  1. Prepare the crank arms: Clean the pedal threads and apply a small amount of grease to prevent seizing.
  2. Identify left and right pedals: The right pedal (R) screws in normally (clockwise), while the left pedal (L) screws in counterclockwise.
  3. Hand-tighten first: Start threading each pedal by hand to avoid cross-threading.
  4. Use an 8mm Allen wrench [paid link]: Insert it into the end of the spindle and tighten securely.
  5. Torque to specification: Shimano recommends 35–55Nm for proper installation. Over-tightening may damage the threads, while under-tightening can lead to a loose pedal.

Step 2: Adjusting the Pedal Tension

The PD-5800 features an adjustable spring tension system, which controls how easily the cleats engage and release. Proper tension ensures efficient power transfer and prevents accidental disengagement.

How to Adjust the Tension

  1. Locate the adjustment screw: It’s on the rear of the pedal, near the retention mechanism.
  2. Use a flat-head screwdriver: Turn clockwise to increase tension (harder to clip out) or counterclockwise to decrease tension (easier to clip out).
  3. Balance both sides: Ensure both pedals have the same tension setting to avoid uneven engagement.
  4. Test and refine: Clip in and out multiple times to find the optimal setting for your riding style.

Step 3: Maintaining the PD-5800 Pedals

Regular maintenance keeps your pedals functioning smoothly and extends their lifespan.

Cleaning and Lubrication

  1. Wipe down after every ride: Use a clean cloth to remove dirt and moisture, especially after wet rides.
  2. Deep clean monthly: Use a degreaser to remove grime from the pedal body and spindle.
  3. Lubricate moving parts: Apply Shimano pedal grease to the engagement mechanism for smooth operation.

Servicing the Bearings

The PD-5800 uses sealed bearings that generally require little maintenance. However, if they feel rough or develop play, they need servicing.

  1. Remove the spindle assembly: Use an 8mm Allen wrench [paid link] to unscrew the spindle from the pedal body.
  2. Inspect the bearings: Check for roughness or excessive play.
  3. Regrease or replace bearings: Apply fresh grease or replace worn-out bearings as needed.
  4. Reassemble carefully: Tighten the spindle back into the pedal body securely.

Troubleshooting Common PD-5800 Pedal Issues

1. Pedals Feel Loose

  • Cause: Loose pedal installation or worn bearings.
  • Solution: Check torque settings and inspect bearings.

2. Difficulty Clipping In or Out

  • Cause: Incorrect tension settings or dirt buildup in the engagement mechanism.
  • Solution: Adjust tension and clean the pedal body.

3. Squeaking or Creaking Sounds

  • Cause: Dry pedal spindle or contaminated cleats.
  • Solution: Lubricate the spindle and clean the cleats.

Conclusion

Proper installation, adjustment, and maintenance of your Shimano PD-5800 pedals ensure smooth operation, safety, and longevity. By installing correctly, adjusting tension to your preference, and performing regular maintenance, you’ll maximize performance and avoid common issues.

By following this guide, you can confidently maintain your PD-5800 pedals for years of smooth and efficient riding.
