Shimano FC-5700 [paid link] Crankset Maintenance Plan

The Shimano FC-5700 [paid link] crankset is a well-known component in the road cycling world, offering riders a durable and reliable drivetrain for various road biking applications. However, to ensure that your Shimano FC-5700 [paid link] remains in top shape for years, regular maintenance and care are essential. This article will provide you with a detailed maintenance plan, focusing on the proper steps to keep your Shimano FC-5700 crankset performing at its best.

Routine Cleaning and Inspection

Proper cleaning and regular inspections are the cornerstones of a maintenance plan for the Shimano FC-5700 crankset. Dirt, grime, and chain lubrication buildup can interfere with the smooth operation of the crankset. Here’s how to keep it clean:

  1. Cleaning: After each ride, take a few minutes to wipe down the crankset with a clean cloth. Use a mild soap solution and water to remove dirt and grease that may have accumulated. Avoid using harsh chemicals or solvents, as they can damage the protective finish of the crankset.
  2. Detailed Inspection: During cleaning, inspect the crankset for any signs of wear or damage. Look for cracks, bent crank arms, or signs of corrosion. Check the chainring teeth for any rounding or deformation. If you notice any damage or irregularities, address them immediately to avoid further issues.

Lubrication of Key Components

Lubricating moving parts is vital for smooth performance and the prevention of corrosion. The Shimano FC-5700 crankset has several key components that require lubrication.

  1. Pedal Threads: Apply a thin layer of grease to the pedal threads before installing them. This helps prevent rust and makes it easier to remove the pedals later.
  2. Bottom Bracket Interface: The interface between the crankset and the bottom bracket should be lubricated to ensure smooth rotation and to prevent creaking sounds. Use high-quality grease on the axle interface before installing the crankset.
  3. Crank Arm Bolts: Apply a small amount of grease to the crank arm bolts before tightening them. This not only ensures easy removal but also prevents the bolts from seizing over time.

Tightening and Adjustment

Proper torque and adjustments are critical for the longevity of the Shimano FC-5700 crankset. If your crankset is loose or misaligned, it could affect shifting performance and overall riding efficiency.

  1. Crank Arm Bolt Tightening: Over time, crank arm bolts may loosen due to repeated pedaling and vibration. Ensure that your crank arm bolts are tightened to the manufacturer’s recommended torque specifications, typically around 12-14 Nm for the FC-5700.
  2. Chainring Bolts: Periodically check the chainring bolts to ensure they are secure. These bolts should also be tightened to the correct torque setting—usually around 8-10 Nm.
  3. Bottom Bracket Tightening: The bottom bracket interface needs to be checked as well. If you notice any play or unusual noises coming from the bottom bracket, tighten it to the proper torque value. The FC-5700 crankset is compatible with Shimano’s Hollowtech II bottom bracket system, and this should be properly adjusted to prevent any issues.

Bearings and Bottom Bracket Maintenance

Maintaining the bearings and bottom bracket is critical for ensuring smooth power transfer. The FC-5700 uses Shimano’s Hollowtech II technology, which incorporates external bearings housed in the crankset’s bottom bracket.

  1. Bearing Inspection: Spin the crankset by hand and listen for any roughness or resistance from the bearings. If the bearings feel gritty or rough, they may need to be replaced. External bearings typically last between 2,000 to 3,000 miles depending on riding conditions.
  2. Bottom Bracket Maintenance: Inspect the bottom bracket for signs of damage or wear. If you detect any play in the bottom bracket or excessive resistance, it might be time to service or replace it. Ensure that the bottom bracket is correctly installed with proper lubrication to avoid damaging the crankset.

Chainring and Crank Arm Alignment

A common cause of shifting issues and drivetrain misalignment on the FC-5700 is incorrect chainring or crank arm alignment.

  1. Chainring Check: Over time, chainrings can become misaligned or suffer from bent teeth. If the teeth are excessively worn or misshapen, replace the chainring. Proper alignment of the chainring ensures smooth shifting and prevents the chain from slipping.
  2. Crank Arm Alignment: Misaligned crank arms can cause pedaling inefficiency and discomfort. When reinstalling the crank arms, make sure that they are properly aligned and securely fastened. Pay attention to the manufacturer’s recommended crank arm torque to prevent loosening during use.

Chain and Drivetrain Maintenance

The performance of your Shimano FC-5700 crankset is closely tied to the health of your chain and other drivetrain components. Keeping these parts clean and properly adjusted will help to maintain smooth operation.

  1. Chain Cleaning and Lubrication: Clean your chain regularly to remove dirt, oil, and grit. A dirty chain can cause unnecessary wear on the chainring teeth and the crankset. Lubricate the chain after cleaning with a suitable chain lube to ensure smooth shifting.
  2. Chain Wear Check: Over time, chains stretch, and worn chains can damage the chainring teeth and derailleur components. Use a chain checker tool to monitor chain wear. Replace the chain if it shows excessive wear, as this will prolong the life of the crankset and other drivetrain components.

Crankset Replacement Indicators

While the Shimano FC-5700 crankset is built to last, there may come a time when it needs to be replaced. Keep an eye out for the following indicators:

  1. Excessive Chainring Wear: If the teeth on the chainring are severely worn or damaged, it may cause shifting issues or even chain slipping. If the damage is beyond simple repair or reshaping, consider replacing the chainring or crankset.
  2. Worn Bearings: If the crankset starts to feel rough or there is noticeable resistance when spinning the pedals, it could indicate bearing failure. Replace the bearings if they are no longer smooth.
  3. Crank Arm Damage: If the crank arms are cracked, bent, or show signs of significant wear, it is time for a replacement.

Conclusion

A well-maintained Shimano FC-5700 crankset can offer years of reliable performance. Regular cleaning, lubrication, torque checks, and bearing maintenance are essential to keeping the crankset in optimal condition. By following the maintenance plan outlined in this guide, you can ensure that your Shimano FC-5700 crankset remains a smooth, efficient, and durable component of your road bike for years to come.
