Tools Required [paid links]
Before starting, gather the following tools:
- Cassette lockring tool [paid link] (Shimano-compatible)
- Chain whip
- Adjustable wrench or breaker bar
- Allen wrenches
- Torque wrench (for precise tightening)
- Cleaning brush and degreaser
- Shop rags or paper towels
- New cassette (if replacing)
How to Install the CS-4700 Cassette
Step 1: Remove the Old Cassette
- Shift the chain onto the smallest rear sprocket to relieve tension.
- Remove the rear wheel from the bike.
- Hold the cassette in place using a chain whip to prevent it from rotating.
- Use the lockring tool [paid link] and wrench to loosen and remove the lockring counterclockwise.
- Slide off the old cassette and inspect the freehub body for wear or dirt buildup.
Step 2: Prepare the Freehub Body
- Wipe down the freehub body with a clean rag to remove grime and old lubricant.
- Apply a thin layer of grease to the splines to prevent corrosion and ease future removal.
Step 3: Install the New CS-4700 Cassette
- Align the largest sprocket with the splines on the freehub.
- Stack the remaining sprockets and spacers in the correct order (refer to the manual if needed).
- Secure the cassette with the lockring, threading it clockwise by hand.
- Tighten the lockring using the lockring tool [paid link] and a torque wrench [paid link], setting it to 40 Nm (recommended by Shimano).
- Reinstall the wheel onto the bike and check alignment.
Adjusting the CS-4700 Cassette for Optimal Shifting
Proper indexing ensures crisp, reliable gear changes. Follow these steps to fine-tune shifting:
Check the Derailleur Alignment
- Ensure the rear derailleur hanger is straight; a bent hanger can cause poor shifting.
- Use a derailleur hanger alignment tool if necessary.
Fine-Tune Indexing Adjustments
- Shift to the smallest sprocket and check cable tension.
- Adjust the high limit screw (H) so the derailleur aligns with the smallest sprocket.
- Shift to the largest sprocket and adjust the low limit screw (L) for proper alignment.
- Fine-tune indexing with the barrel adjuster by turning it counterclockwise to increase cable tension or clockwise to reduce it.
- Test shift across all gears, ensuring smooth transitions without skipping or hesitation.
How to Maintain the CS-4700 Cassette
Regular Cleaning and Lubrication
- Remove the rear wheel and take off the cassette if necessary.
- Use a degreaser and a brush to clean between the sprockets.
- Rinse and dry thoroughly before reinstalling.
- Lightly lubricate the chain to reduce wear on the cassette.
Checking for Wear and Replacement Signs
- Look for shark-tooth shaped sprockets, indicating wear.
- Test for skipping gears under load—this may signal a worn cassette.
- If a new chain skips on an old cassette, it’s time for a replacement.
Troubleshooting Common Issues
Skipping Gears or Inconsistent Shifting
- Check cable tension and adjust the barrel adjuster.
- Ensure the cassette is properly tightened.
- Inspect the derailleur hanger for misalignment.
Cassette Noise or Grinding Sounds
- Clean and lubricate the cassette.
- Check the chain for excess wear—a stretched chain accelerates cassette wear.
- Verify the lockring is torqued correctly.
