👨🔧- The trick in Michel (the corner of the expert)
* "Hi the artists of the trajectory! If there is a piece on which it is forbidden to make improvisation or savings of candlelight, it is the front rocket nut. If you lose a pontoon nut, you risk a penalty; If you lose this special nut Birelart, it's the front wheel leaving Kart at 110 km / h, and there, the track outlet is immediate and brutal !
My trick of old wolf circuits for your train before: check the braking system of the nut and bare the shock wrench !
This nut is called "special" because it has a mechanical braking system (deformed thread, nylon ring or pressure flange) to never loosen all with vibrating vibrations. By disassemble and reassemble your wheels to adjust the tire pressure, this system is used. If you arrive at screwing the nut by hand to the end without feeling resistance, it's tired. Change it immediately !
Second tip: At the booth, always use a good T key or a manual ratchet wrench to tighten it. The shock wrench (striper) will destroy the end thread of the rocket or nut in less than two. It is firmly squeezed, we make sure there is no radial game on the hub, and we validate with the beta pin of safety if your rocket is equipped. Security above all! "*
- The assembly & control guide: step by step
1.Nettoyage and inspection of the axis:2 min.Put the kart on his carriage. Remove the safety pin (if present) and disassemble the old nut. Pass a cleaning shot brake and clean cloth on the male thread of the Birelart rocket to remove old metal debris and dirty grease.
2.Place of the wheel or hub:3 min.Slide your front hub or rim on the rocket axis. Adjust your track adjustment rings (rocket washers) to obtain the desired front train width according to your chassis settings.
3.ser manual of the special nut:2 min.Present the special Birelart nut straight in front of the thread. Progress the first laps in hand to be sure not to bite the thread. Take your manual key and tighten firmly.
4.Validation functional game:2 min.Follow the trick in Michel: Turn the wheel by hand. It must rotate perfectly free (without hard point at the bearings), but without presenting the slightest game back and forth when you shake it firmly. Replace the elastic safety pin.

Q: Should we put from the net brake (Loctite type) on the rocket nut ?
A: No, it's strongly not recommended. The rocket nut is designed to be disassembled very regularly during a race weekend (dry tire change / rain, change of the track width before). Put the net brake would make disassembly at the very difficult booth and could damage the threads. The mechanical self-locking system of this special nut is amply enough to guarantee security.
