Secure the lock of your transmission while reducing the masses in rotation thanks to theClutch nut in Ergal origin TM KART. Cut in the mass in an aluminum alloy with very high mechanical strength (Ergal 7075 T6), this central nut guarantees an absolute maintenance of your clutch nut on the primary gearbox shaft.
Presented under the view 3 (marker 26) on the technical scheme of the TM Kart KZ-R3 clutch, this original nut enjoys a reworked geometry to adapt to the last evolution of Italian transmissions. Its Ergal design allows a valuable weight gain compared to a conventional steel nut, which decreases the inertia on the primary tree and promotes even more brighter and frank climbs.
⚠️ Important - Compatibility Mounting:
This Ergal nut is designed exclusively to work in combination with the walnut / Clutch Tambourine "New Type" (also available for sale in this section of the site). It does not adapt to the old models of tambourines.
* "Hi mechanical enthusiasts! A clutch nut in Ergal, it's the beautiful workpiece machined, but beware: the Ergal, it's noble and light aluminum! We do not treat it as a solid steel nut.
My stand trick for mounting this nut (view 3): the clean sleeve, the average brake and the Dyna key !
Before placing this nut on your tambourine 'new type', perfectly clean the brake cleaner tapping and drop a drop of blue fillet brake (average force) on the thread of the primary shaft. Do not use a shock key (pneumatic firecracker) that would destroy the imprint of this nut in Ergal !
Screw it by hand, then use a suitable clutch nut blocker and a 6-piece socket perfectly clean mounted on torque wrench. Tighten to torque recommended by TM KART. A mounting on the brake and the right couple is the assurance of a locked transmission that will never move in the sleeve! "*
After installing the tambourine / clutch walnut "new type" and its wedge washer, perfectly clean the thread of the shaft with brake cleaner.
Follow the Tip in Michel: Remove a medium (blue) brake tip on the shaft thread to secure the lock.
Engage the Ergal nut (view 3) by hand. Block the tambourine with the dedicated hold tool and tighten to the torque wrench (6-pin sleeve) with the factory recommended torque.
Check that the tambourine has no axial game and rotates freely with the shaft. You can now install the pressure tray and the disks !
Q: Why use an ergal nut rather than a steel nut on the clutch ?
A: Ergal (Aluminum 7075 T6) offers a mechanical strength very close to steel while being about three times lighter. On a component attached directly to the rotating transmission shaft, this weight reduction decreases the inertia and improves the reactivity of the engine to the delivery of the gases.
Q: What component of the exploded view matches this nut ?
A: On the official technique scheme of the clutch (Tavola 6 - Frizione), this nut is identified under the reference View 3/26. It comes to the center of the clutch walnut (marker 10).
Q: Can I get this Ergal nut on an old clutch tambourine ?
A: Not. This nut imperatively requires the joint montage of the clutch "new type" nut. If you have the old Tambourine model, you must also order the new compatible tambourine available in our shop.
Guarantee a perfect lock and surgical disengagement on your high-engine thanks to the Official TM Kart Clutch Press Tray Designed for KZ-R3 Engine. Mistress transmission part, this pressure plate applies the radial strength of the springs on the stack of the stacked discs and smooth to transmit the entire power of the block R3 to the gearbox.
Machined in a high rigidity aluminum alloy, this presser tray benefits from a geometry reworked by the TM KART race service exclusively dedicated to the KZ-R3 generation. It avoids any deflection under stolen departures or on the fly passages, ensuring instant biting without residual skating. Its perfectly flat friction surface and anti-friction treatment extend the lifetime of your clutch discs and ensure absolute constancy, handle after handle.
Ensure the precise and fluid trigger of your transmission with the Internal clutch thrust rod 146.2 mm TM Kart. Original piece for KZ10B, KZ10C and R (R1, R2, R3) series motors.
Guarantee a perfect alignment and an axial game mastered to your transmission thanks to theTM KART Original Clutch Support Spacer. Essential wedging piece interposed at the clutch support on the primary shaft, this machined ring ensures the exact positioning of the movable crew.
Made in a special steel resistant to high axial loads and high-speed friction, this original spacer does not deform under the pressure of the tray and resists mechanical wear. Its irreproachable dimensional precision avoids any counterpour or side stress on the gnat, guaranteeing a fluid shift and an excellent durability on the entire engines TM Kart KZ10C, KZ-R1, KZ-R2 and KZ-R3.
On gelling karting engines (category kz) like the famous TM R1 TM R2 and TM R3, internal tightness management is a key factor in performance and reliability. This microphone 5x9x2 mm spi seal Ensures a critical function at the heart of the crankcase.
