The TIME MX 4 [paid link] pedals are known for their durability, lightweight construction, and unique ATAC (Auto Tension Adjustment Concept) engagement system. However, even well-engineered pedals can develop noise or stiffness over time due to wear, contamination, or improper installation. This guide provides a comprehensive, step-by-step approach to diagnosing, fixing, and preventing these common issues so your MX 4 [paid link] pedals continue to perform smoothly and quietly.
Tools Required
- 8mm hex wrench
- 15mm pedal wrench [paid link]
- Torque wrench [paid link] (Nm scale)
- Grease (Teflon or lithium-based)
- Isopropyl alcohol and clean rags
- Bearing puller and press (optional for servicing)
- Replacement pedal bearings and bushings (if required)
Understanding the TIME MX 4 Pedal Design
The TIME MX 4 pedals use a composite body and a steel axle, making them both lightweight and strong. The ATAC mechanism provides self-cleaning engagement, ideal for muddy conditions. The pedal relies on bushings and cartridge bearings inside the axle assembly for smooth rotation.
A key design advantage is the springless ATAC bar system, which provides consistent entry and release tension without user adjustment. When noise or stiffness occurs, it usually indicates dirt ingress, dry bearings, or axle misalignment rather than an issue with the retention system itself.
Diagnosing Noisy TIME MX 4 Pedals
Noise from the MX 4 pedals can originate from multiple sources. Pinpointing the cause ensures a correct fix and avoids unnecessary part replacements.
Step 1: Identify the Noise Source
Rotate the crank slowly and listen carefully.
- If the clicking or creaking is synchronized with the pedal rotation, the issue likely comes from the pedal bearings or axle interface.
- If the sound appears only when clipped in, the cleat-to-pedal contact points may be dry or contaminated.
Step 2: Check Pedal Installation Torque
Improper torque at the crank arm can lead to creaks. Ensure each pedal is tightened to 35–40 Nm using a torque wrench [paid link]. Clean the threads and apply a thin layer of grease before reinstalling.
Step 3: Inspect Cleats and Shoes
Worn or dirty cleats often produce metallic clicks. Remove them from the shoes, clean thoroughly, and inspect for uneven wear. Replace cleats if the engagement edges appear rounded.
Step 4: Examine Bearings and Bushings
Hold the pedal body and rotate it by hand.
- A gritty feeling indicates contaminated bearings.
- Lateral play suggests worn bushings or loose axle hardware.
If either is present, proceed to bearing service.
Fixing Stiff TIME MX 4 Pedals
Stiffness is a symptom of friction within the axle assembly or between the pedal body and bearing interfaces. Follow these steps to restore smooth operation.
Step 1: Remove the Pedals
Using an 8mm hex or a 15mm wrench, remove both pedals. Note that the left pedal has reverse threading. Clean the threads and set aside.
Step 2: Disassemble the Axle Assembly
Carefully unscrew the end cap using a hex key. Slide out the axle assembly. You’ll find a bushing on the crank side and a sealed cartridge bearing near the outer end.
Clean all components with isopropyl alcohol and a rag. Avoid using degreasers that can damage the internal seals.
Step 3: Re-Grease and Reassemble
Apply a thin layer of grease to:
- The inner bushing surface
- Bearing seat
- Axle threads and contact areas
Reinsert the axle and tighten the end cap to manufacturer specification (approximately 3–4 Nm). Over-tightening can compress the seals and increase friction.
Step 4: Test for Smoothness
Before reinstalling on the bike, rotate the pedal by hand. It should spin freely with minimal resistance. If stiffness remains, replace the bearing and bushing kit—TIME sells these as service parts compatible with the MX 4.
Eliminating Persistent Pedal Noise
If noise persists after servicing, the cause may not be internal. Consider the following:
- Crank Interface: Remove and reinstall the pedals with fresh grease on the threads. Dry interfaces often creak under load.
- Shoes and Cleats: Use a small amount of dry PTFE lubricant on the cleat interface. Avoid oil-based lubricants that attract dirt.
- Bottom Bracket or Chainring Bolts: Pedal noises can sometimes resonate from nearby components. Check these areas to rule out false sources.
Preventive Maintenance for TIME MX 4 Pedals
Routine care keeps your pedals operating smoothly and reduces wear. TIME’s ATAC mechanism is self-cleaning, but dirt buildup around the spring and bar can still affect engagement.
Cleaning Routine
After every few rides—especially in wet or muddy conditions—rinse the pedals gently with low-pressure water. Use a soft brush to remove grime. Avoid power washers, as high pressure can drive water into the bearings.
Lubrication Schedule
Every 3–6 months (or 1,000 km), remove the pedals, clean the axles, and reapply fresh grease. For frequent off-road riders, perform this service more often.
Bearing Replacement
TIME recommends bearing service annually under normal conditions. Replace the outer sealed bearing and inner bushing as a set to maintain smoothness and alignment.
Optimizing Pedal Performance
To enhance pedal feel and longevity:
- Use TIME-specific cleats only; mixing brands causes poor engagement and premature wear.
- Ensure cleat bolts are tightened evenly and secured with blue threadlocker.
- Maintain shoe sole alignment—misaligned soles can cause uneven pedal engagement.
With proper attention, the MX 4 pedals deliver smooth entry, consistent release, and long-term durability even under heavy use.
Troubleshooting Summary
| Symptom | Likely Cause | Corrective Action |
|---|---|---|
| Creaking noise under load | Dry pedal threads or loose installation | Clean and re-grease threads; torque to 35–40 Nm |
| Grinding or stiffness | Contaminated bearings or bushings | Clean and re-grease; replace if necessary |
| Click during pedaling | Worn or dirty cleats | Clean or replace cleats |
| Play in pedal body | Worn bushing or loose end cap | Replace bushing; torque end cap properly |
Conclusion
Noisy or stiff TIME MX 4 pedals are typically easy to fix with the right maintenance approach. Regular cleaning, timely lubrication, and periodic bearing service ensure reliable engagement and long-lasting performance. By understanding the design and following precise diagnostic steps, riders can keep their MX 4 pedals running quietly and smoothly for many seasons.
