The TIME ATAC XC 4 [paid link] pedals are renowned for their reliable engagement mechanism, lightweight composite body, and long-lasting performance in cross-country and gravel riding conditions. However, like all clipless pedals, the bearings eventually wear down due to mud, water, and general use. Regular servicing and bearing replacement are essential to maintain smooth rotation, reduce friction, and extend pedal life. This guide provides a detailed, step-by-step explanation on how to properly replace or service the bearings in your TIME ATAC XC 4 [paid link] pedals.

Tools Required

  • 8 mm Allen key
  • 6 mm Allen key
  • Flathead screwdriver
  • Torque wrench [paid link] (2–14 Nm range)
  • Needle-nose pliers
  • Bearing puller or drift punch
  • Small mallet
  • High-quality waterproof grease
  • Replacement bearing kit (specific to TIME ATAC XC 4)
  • Clean rag and degreaser

Understanding the TIME ATAC XC 4 Bearing System

The TIME ATAC XC 4 pedals use a dual-bearing system that combines a needle bearing on the inboard side and a cartridge bearing on the outboard side. This design balances low friction with robust load distribution, making it suitable for off-road conditions. The pedal spindle houses both bearing types, protected by internal seals that prevent water and grit ingress. Over time, these seals degrade, and grease breaks down, leading to play, creaks, or stiffness in pedal rotation.

Servicing these bearings ensures that the pedal remains efficient and prevents irreversible spindle wear—a costly issue that can only be resolved by full pedal replacement.

Signs That Your Bearings Need Servicing

Before beginning the replacement process, it’s important to identify whether the bearings actually require service. Common symptoms include:

  • Noticeable side-to-side play in the pedal body.
  • Grinding or rough rotation when spinning the pedal by hand.
  • Clicking or creaking sounds under load.
  • Resistance or stiffness when clipping in or out.
  • Visible dirt or corrosion near the spindle interface.

If any of these issues occur, it’s advisable to service both pedals, as wear tends to develop symmetrically.

Step-by-Step Bearing Removal and Replacement

Removing the Pedal from the Crank Arm

Start by using an 8 mm Allen key on the spindle end to unscrew the pedal counterclockwise (standard thread on the right, reverse on the left). Hold the opposite crank arm for stability and apply steady torque until the pedal disengages completely.

Accessing the Bearing Assembly

With the pedal removed, use a flathead screwdriver to gently pry off the end cap on the outboard side. Underneath, you’ll find a retaining nut that secures the spindle assembly. Using a 6 mm Allen key, carefully remove this nut while holding the spindle in place to prevent damage to the threads.

Extracting the Spindle and Bearings

Pull the spindle straight out of the pedal body. The cartridge bearing and inner sleeve will come out together. Next, use needle-nose pliers or a bearing puller to remove the old cartridge bearing from the outer side of the pedal body. For the inboard needle bearing, gently tap it out using a drift punch and small mallet. Take care not to damage the internal housing or seals.

Cleaning and Inspection

Use a clean rag and degreaser to remove old grease, dirt, and debris from the spindle and bearing seats. Inspect the spindle for pitting, corrosion, or deformation. If damage is visible, replacement of the entire spindle is recommended before reassembly.

Installing the New Bearings

Apply a thin layer of grease to the new bearing seats. Press the new needle bearing into the inboard housing first, ensuring it sits flush and evenly. Then insert the cartridge bearing on the outboard side, using a bearing press [paid link] or gentle mallet taps to seat it securely. Avoid striking the bearing directly to prevent seal damage.

Reassembling the Pedal

Lightly grease the spindle, then slide it through the pedal body. Reinstall the retaining nut and tighten it to 5–6 Nm using a torque wrench [paid link]. Refit the dust cap by pressing it firmly into place.

Final Installation and Testing

Reattach the pedal to the crank arm, applying a small amount of grease to the pedal threads. Tighten to 30–35 Nm torque using an 8 mm Allen key. Spin the pedals to confirm smooth, consistent rotation without lateral play or grinding.

Routine Maintenance Recommendations

To ensure optimal longevity, TIME recommends servicing the ATAC XC 4 bearings every 3,000–5,000 km, or more frequently if you ride in muddy or wet environments. Light cleaning after every few rides can also help reduce premature wear. Always reapply waterproof grease to prevent moisture ingress, and check the pedal tension adjustment regularly to maintain consistent engagement feel.

If you frequently power wash your bike, avoid directing high-pressure water at the pedal axles, as this can force contaminants into the bearing seals and rapidly degrade lubrication.

Performance Optimization Tips

To enhance pedal longevity and minimize friction, consider using ceramic hybrid bearings as an upgrade option. These offer reduced rolling resistance and improved corrosion resistance, though they require careful installation to avoid cracking.

Additionally, regularly inspecting the ATAC spring mechanism ensures that engagement remains consistent. A stiff or slow-release feeling can sometimes be traced back to contaminated bearings or dry seals. Keeping the bearing system clean will maintain the responsive feel the TIME ATAC XC 4 pedals are known for.

Compatibility and Replacement Notes

The TIME ATAC XC 4 uses the same spindle and bearing configuration as the ATAC XC 6 [paid link] and XC 8 models, meaning bearing kits are interchangeable across these pedals. However, the XC 2 and MX series use slightly different dimensions, and their parts are not directly compatible. Always verify the part number when ordering replacement kits to ensure proper fitment.

When servicing, avoid substituting generic bearings that don’t match the original specifications. Precision tolerance is essential for maintaining the correct seal pressure and smooth spindle rotation.

Troubleshooting After Reassembly

If the pedal still feels rough after servicing, recheck the bearing seating depth and verify that the spindle is aligned correctly. Grinding or stiffness usually indicates that one bearing is not fully pressed or that excess grease is creating hydraulic pressure. Loosen the retaining nut slightly and retest.

Persistent lateral play often results from worn bearing seats or a missing spacer washer. Inspect these components carefully before assuming the new bearings are faulty.

Conclusion

Replacing or servicing the bearings in your TIME ATAC XC 4 pedals is a precise yet straightforward procedure that significantly extends their operational life. With proper care, lubrication, and attention to detail during reassembly, your pedals will spin smoothly for thousands of kilometers. Regular inspection not only improves performance but also prevents costly damage to the spindle or pedal body.

By maintaining your ATAC XC 4 pedals in optimal condition, you ensure the same reliable engagement, power transfer, and comfort that TIME pedals are celebrated for in competitive and recreational cycling alike.
