Secure the lock of your transmission with a valuable weight gain on the rotating masses thanks to theClutch nut in an official black black tm kart (ref 18tm49057.2). Cut in the mass in a high strength aluminum alloy (Ergal 7075 T6), this central nut guarantees a perfect maintenance of your clutch nut on the primary box of box.
On the official technique pattern of the clutch assembly, this original nut enjoys a reworked geometry to adapt to the latest evolution of TM Kart transmissions. Treated with a superb black Anodizing (Total Black), It offers increased thermal and mechanical resistance to clamping stresses and temperature variations. Its lightweight design reduces inertia on the primary tree, promoting even more frank climbing.

This Nut in Ergal Black Reference 18tm49057.2 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! The clutch nut in Ergal, it's super nice room, but beware: Ergal is noble and ultra-light aluminum! We do not treat it as an old solid steel nut.
My stand trick for mounting this nut 18TM49057.2: the clean sleeve, the average brake and the Dyna key !
Before placing this black nut on your tambourine 'new type', drop a drop of blue fillet brake (average force) on the thread of the primary shaft. Do not use a shock wrench (pneumatic firecracker) that would destroy black anodizing and might be misgiving the nutty nut !
Tighten it by hand, then use a suitable clutch-clutch lock and a 6-piece socket perfectly clean mounted on torque wrench. Apply the tightening torque recommended by TM Kart without exceeding the prescribed values. A mounting on the brake and the right couple is the assurance of a locked transmission that will never loosen in the race! "*
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 black Ergal nut (ref 18tm49057.2) 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 ?
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 is the reference TM KART 18TM49057.2 ?
A: This is the official reference TM Kart for the black Ergal clutch nut specific to the tambourine subset / clutch walnut "new type".
Q: Can I reuse this nut in Ergal during several demonstrations ?
A: Yes, as long as you use a suitable tool (fitting 6-pin) to not mark its footprint and carefully clean the brake residues on its thread for each reassembly.
