🔧 CFMoto Tightening Sleeve
📦 Part Number: 0800-014008
⚙️ Tightening Sleeve · Locking Bushing · OEM Spec
📍 Installation Location: Drivetrain / Bearing or gear locking position
✅ Single unit · Premium metal · Direct fit · Compatible with multiple CFMoto ATV/SSV/UTV models
This is a CFMoto OEM-spec Tightening Sleeve, part number 0800-014008, sold as a single unit. This tightening sleeve is a precision metal bushing used in the drivetrain or engine to lock bearings, gears, or other rotating components in place. It provides reliable axial positioning and clamping force through taper fit or threaded locking — ensuring precise installation and stable operation of drivetrain components.
Over time, the original tightening sleeve may wear, deform, or suffer thread damage under high-load operation, leading to reduced clamping force, axial play of bearings or gears, noise, or even drivetrain failure. Replacing with an OEM-spec sleeve is essential to restore drivetrain precision and reliability.
✅ OEM Quality Assurance: Manufactured strictly to CFMoto original technical standards. Dimensions, taper, and thread specifications are identical to the genuine part, ensuring a perfect replacement and reliable locking performance.

- 💪 Direct Fitment: Direct replacement for the original part — no modifications required.
- 🔄 Direct Replacement: Replaces worn, deformed, or thread-damaged original tightening sleeves.
• Axial play or abnormal noise from the drivetrain.
• Bearings or gears feel loose during operation — insufficient clamping force.
• Damaged threads, deformation, or visible wear on the sleeve (visual inspection).
• Sleeve found to be beyond wear limit during disassembly for maintenance.
• When replacing bearings or gears, replacing the tightening sleeve at the same time is recommended to ensure locking reliability.
If any of these occur, replace the tightening sleeve promptly to restore drivetrain precision and reliability.
1. Confirm the sleeve is the correct 0800-014008 matching the original.
2. Disassemble relevant drivetrain components to access the sleeve.
3. Use the proper tool to remove the old sleeve, being careful not to damage the shaft or bearing housing.
4. Clean the mounting journal and mating surfaces, checking for scoring or wear.
5. Install the new sleeve in the correct orientation, using the proper tool or torque to OEM specifications.
6. Confirm proper locking — the bearing or gear should have no axial play.
7. Reinstall drivetrain components following the service manual.
