സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും

This section outlines the general steps for installing the Ratchet LN Freehub Body Upgrade Kit. Professional installation is recommended if you are unfamiliar with bicycle hub maintenance.

ആവശ്യമായ ഉപകരണങ്ങൾ (ഉൾപ്പെടുത്തിയിട്ടില്ല):

• കാസറ്റ് ലോക്കിംഗ് ഉപകരണം
• ചെയിൻ വിപ്പ്
• Appropriate wrenches or hex keys for axle removal

ഇൻസ്റ്റലേഷൻ ഘട്ടങ്ങൾ:

1. Remove Wheel: Carefully remove the rear wheel from your bicycle.
2. Remove Cassette: Using a chain whip and cassette lockring tool, remove the cassette from the existing freehub body.
3. Remove End Caps: Remove the drive-side and non-drive-side end caps from the hub axle. These usually pull off by hand or require light prying.
4. Remove Existing Freehub Body: Pull the existing freehub body directly off the hub axle. The pawls and springs (if applicable) will be exposed.
5. Clean Hub Shell: Thoroughly clean the inside of the hub shell and the axle to remove any old grease, dirt, or debris.
6. Install Ratchet Rings and Springs:
   • Apply a thin layer of DT Swiss special grease to the teeth of both ratchet rings.
   • Place one spring into the hub shell, followed by one ratchet ring, ensuring the teeth face inwards.
   • Place the second spring into the freehub body, followed by the second ratchet ring, ensuring the teeth face outwards.
7. Install New Freehub Body: Carefully slide the new Ratchet LN freehub body onto the hub axle, aligning the ratchet rings. Ensure the springs are properly seated and the ratchet rings engage smoothly. You may need to gently rotate the freehub body to help the teeth align and engage.
8. Reinstall End Caps: Push the end caps back onto the hub axle until they are fully seated.
9. Reinstall Cassette: Install your Shimano HG 11-speed mountain bike cassette onto the new freehub body and tighten the lockring to the manufacturer's specified torque.
10. വീൽ വീണ്ടും ഇൻസ്റ്റാൾ ചെയ്യുക: Mount the rear wheel back onto your bicycle and ensure all quick releases or thru-axles are properly secured.

പ്രവർത്തന നിർദ്ദേശങ്ങൾ

Once installed, the DT Swiss Ratchet LN Freehub Body operates automatically as part of your bicycle's drivetrain. The primary function is to allow the rear wheel to freewheel when you stop pedaling and to engage the drivetrain when you resume pedaling.

• ഇടപഴകൽ: The 36-tooth ratchet mechanism provides a precise and quick engagement, minimizing pedal lag and transferring power efficiently to the rear wheel.
• ഫ്രീ വീലിംഗ്: When you stop pedaling, the ratchet system disengages, allowing the wheel to spin freely.
• ശബ്ദം: The Ratchet System typically produces a distinct, crisp freewheeling sound. This is normal and indicates proper function.

മെയിൻ്റനൻസ്

Regular maintenance ensures the longevity and optimal performance of your DT Swiss Ratchet LN Freehub Body.

• വൃത്തിയാക്കൽ: Periodically remove the freehub body (as per installation steps 3-4) and clean the ratchet rings, springs, and hub shell interior. Use a clean rag to wipe away old grease and any accumulated dirt or debris. Avoid harsh solvents that could damage seals or bearings.
• ലൂബ്രിക്കേഷൻ: After cleaning, apply a thin, even layer of DT Swiss special grease (or a compatible, non-migrating grease specifically designed for ratchet systems) to the teeth of both ratchet rings and the springs. Do not over-grease, as this can impede engagement.
• പരിശോധന: While performing maintenance, inspect the ratchet rings for any signs of wear, chipping, or damage. Check the springs for deformation or breakage. Inspect the sealed bearings for smooth rotation and any play. Replace any worn or damaged components immediately.
• ആവൃത്തി: Maintenance frequency depends on riding conditions. For frequent or aggressive riding, inspect and lubricate every 3-6 months. For casual riding, once a year may suffice.
