Proper lubrication and cleaning are essential to keep your Shimano FC-4700 [paid link] crankset in top condition and ensure it performs at its best. Regular maintenance not only extends the life of the crankset but also enhances its efficiency, reduces wear, and minimizes the risk of unexpected issues during rides. In this guide, we will walk you through the best practices for keeping your FC-4700 [paid link] crankset clean and well-lubricated.

Importance of Regular Lubrication and Cleaning

The Shimano FC-4700 [paid link] crankset is a highly engineered component designed for smooth performance. However, without proper care, dirt, grime, and moisture can accumulate, causing the moving parts to wear prematurely. Proper lubrication helps reduce friction between the crankset’s parts, while regular cleaning ensures that dirt and debris don’t affect its performance. Both practices contribute to a smoother, more efficient drivetrain, allowing you to enjoy long, trouble-free rides.

Tools and Materials Required

To maintain your Shimano FC-4700 crankset, you will need the following tools and materials:

• Soft brush (e.g., toothbrush or dedicated bike cleaning brush)
• Degreaser
• Chain cleaner (optional but recommended)
• Lint-free cloth
• Bike-specific grease (for crankset threads and bolts)
• Bicycle-specific chain oil or lubricant
• Small bowl for degreaser
• Chain cleaning tool (optional)

Step-by-Step Guide to Cleaning the Shimano FC-4700 Crankset

1. Remove the Crankset (If Necessary):
   • If you’re cleaning thoroughly or applying new grease, you may want to remove the crankset from the bike. For the FC-4700, use a crankset puller tool to safely remove the crank arms from the bottom bracket.
2. Clean the Chainrings:
   • Spray a degreaser directly onto the chainrings to break down grease, grime, and other build-up.
   • Use a soft brush to scrub the surface of the chainrings, paying special attention to the teeth where dirt often accumulates. Be gentle to avoid damaging the teeth or their finish.
3. Clean the Crankset Arms:
   • Using a degreaser, spray the crank arms to loosen any built-up dirt or grease.
   • Scrub the arms with the brush, being careful not to get degreaser on any non-metal surfaces such as decals.
4. Clean the Bottom Bracket Area:
   • If the crankset is still mounted to the bike, use a brush to clean around the bottom bracket and its bearings. Be sure to remove any debris or grit in this area, as this can affect the crankset’s smooth operation.
5. Wipe Down the Entire Crankset:
   • Once the degreaser has had time to break down the grime, use a lint-free cloth to wipe down the crankset. Ensure you remove all excess degreaser and dirt.
6. Apply Lubricant:
   • After cleaning, it’s time to lubricate the parts that require it. Apply a small amount of bicycle-specific grease to the crankset threads and bolts. This is especially important when reassembling the crankset, as grease will help to prevent seizing or creaking.
   • Use a chain-specific lubricant on the chainring teeth. Avoid over-applying, as excess lubricant can attract dirt. A light, even coat will suffice.
7. Reassemble the Crankset:
   • If you’ve removed the crankset for cleaning, carefully reinstall it. Tighten the crank arm bolts to the manufacturer’s torque specifications to avoid damage. Check that everything is properly aligned and secure before riding.

Best Lubrication Practices for the Shimano FC-4700 Crankset

Proper lubrication is essential to ensure your Shimano FC-4700 crankset functions smoothly. Here’s how you can apply lubrication correctly:

1. Apply Grease to the Threads:
   • Whenever you are assembling or reassembling your crankset, apply a small amount of bike grease to the crankset’s threaded areas. This will prevent the bolts from seizing and help protect them from rust.
2. Use Chain Lube on Chainrings:
   • Use a lightweight chain lube on the chainring teeth, as this can improve chain engagement and minimize wear. Wipe off any excess lubricant to prevent dirt from sticking to the chainrings.
3. Lubricate Bearings (If Accessible):
   • Some cranksets allow you to access the bearings directly. If so, apply a thin layer of bike-specific bearing grease to prevent moisture and dirt from entering. Be cautious not to over-grease, as excess grease can attract dirt.
4. Avoid Over-Lubricating:
   • It’s important not to over-lubricate your Shimano FC-4700 crankset. Excess lubricant can attract dirt, leading to build-up that can negatively affect performance. Always wipe away excess lubricant after applying it.

Cleaning and Lubrication Schedule

To maintain optimal performance, it’s essential to follow a regular cleaning and lubrication schedule. Here’s a guideline to follow:

• After Every Ride: Quickly wipe down the crankset to remove any surface dirt and grime. This prevents any build-up from becoming an issue.
• Weekly (or after a muddy ride): Clean the crankset thoroughly with a degreaser, especially if you’ve ridden in wet or muddy conditions. Lubricate the crankset after cleaning.
• Every 200-300 Miles: Perform a deeper clean and reapply lubrication. This includes cleaning the chainrings, checking for wear, and applying fresh grease to the crankset bolts.
• As Needed: If you notice any creaks or if the crankset feels rough while pedaling, it’s time for a deeper inspection and more extensive maintenance.

Maintaining the Shimano FC-4700 Crankset for Longevity

To ensure that your Shimano FC-4700 crankset lasts as long as possible, consider these additional tips:

• Store Your Bike Properly: When not in use, store your bike in a dry place to prevent moisture accumulation on the crankset. This will help avoid rust and corrosion.
• Check for Wear: Regularly inspect your chainrings for wear. If the teeth become significantly worn or misshapen, it’s time to replace them. Similarly, check the bolts and nuts for tightness.
• Clean the Drivetrain: Cleaning not just the crankset but the entire drivetrain regularly will help maintain smooth shifting and prevent premature wear on all components.

By following these steps, you will keep your Shimano FC-4700 crankset in excellent condition, ensuring it continues to perform reliably on every ride. A clean and well-lubricated crankset will not only increase the lifespan of your components but also improve your overall cycling experience.
