This pivot axis (often called rocket screw) is the part that keeps the rocket (stub axle) on the rocket support (C-bracket) of your chassis OTK. Although it is a simple room, its dimensional precision and its hardness are vital: it is it that encys the lateral stresses during turns and potential shocks on the vibrators.
Use a piece of origin OTK Guarantees that the diameter is perfectly calibrated to avoid any "game" in the direction, which is crucial to maintain your front train geometry (camber / hunting).
Specific hardness (HST): The name "HST" (high strength) ensures that the axis will not be twisted during extreme solicitations. A screw purchased in the standard trade might bend, blocking your direction in full turn.
OEM calibration: The diameter is adjusted with strict tolerance to fit perfectly into the rings of your rocket without creating parasitic game.
Maximum security: In karting, the rupture of a rocket screw causes an immediate loss of the front wheel control. The quality OTK is your life insurance on the track.
Finish: Anti-corrosion treatment To prevent the screw from joining the rocket support, facilitating subsequent settings.
"It's a part that many pilots neglect until they have a weird behavior on the front train. The trick: When you disassemble your rocket, roll this axis on a flat surface (such as a marble or a glass plane). If you see the slightest day or an oscillation is that the axis is veiled. Change it immediately, do not try to straighten it. My Pro Council: When reassembling, make sure you use a new Nylstop nut. The safety of your front train must be resting only on fixation elements in perfect condition. "

Q: Can I use a standard DIY screw if I'm in a hurry?
A: Absolutely not. The hardness of the steel of a DIY screw is insufficient for karting shear stresses. Use only the reference OTK original.
Q: How often should I change this axis?
A: There is no fixed time periodicity, but inspect it with every big disassembly of the train before or systematically after a violent track output.
To guarantee a direction without a game, do not forget to check the associated elements:
[Écrous Nylstop M10 OTK] (Essential to block the axis)
[Bagues de fusée] (If you have game, it's often they are worn, not the screw)
