Presentation: the security of the transmission

TheClutch nuts nut is the component that locks the set of clutch clutch on the primary motor shaft TM R1. Subject to extreme rotation and vibration constraints, this nut must guarantee an infallible tightening to avoid any axial game that could destroy the bell or clutch discs.

• High thermal resistance: Designed to maintain its tightening properties despite the significant heating cycles of the clutch in competition.

• Precision thread: Strict machining to fit perfectly with the primary shaft of the RS series motors.

• Maximum security: TMKART original part guaranteeing compliance with high clamp couples recommended by the plant.

- Installation and recommendations

1. Cleaning the thread: Before mounting, thoroughly clean the thread of the primary shaft and nut to eliminate any trace of oil or filings.

2. Brake washer: Always use a new brake washer (if provided by mounting) to secure the nut.

3. Tightening to the couple: The use of a torque wrench is essential. A subclarging may cause loosening the nut, while over-clamping can weaken the primary shaft.

4. Blocking tool: Use a specific clutch nut locking tool to avoid damaging the disks or bell during tightening.

💡 Michel's trick

"A nut nut that loosen in the race, it is the immediate abandonment and often of big collateral damage. The trick: If you do not have a brake washer, a drip 'strong' can be extra security, but beware of disassembly! My Pro Council: Check the condition of the support faces of the nut. If marked, the nut will not properly wear and tightening will not be stable. At the price of the room, do not hesitate to change it preventively during a big box revision. "

❓ FAQ SEO (Frequently Asked Questions)

Q: Is this nut compatible with the TM KZ10C engine ?

A: Although visually similar, check the specific reference. The dr rod motors (R1, R2) may have threading or thickness changes from KZ10 generations.

Q: What is the direction of clamping ?

A: On the majority of TM Racing engines, it is a standard step (tightening to the right), but always check your technical manual specific to the R1 model.

Q: Can we reuse the nut several times ?

A: Yes, if it is not marked and that its thread is perfect. However, in high level competition, it is often replaced by caution when changing the clutch.
