Full description: Why choose the game C4?

In the world of high level karting, the game C4 offers specific benefits:

1. Freedom of total rotation: The game C4 is more "loose" cold. Once the engine is at its maximum operating temperature (in full finish by 35 ° C outside), the components are dilated and the bearing then reaches its perfect operation tolerance, without any clamping.

2. TN9 anti-friction cage: The polymerized polymer cage reduces the inertia of the masses in motion. It allows brighter accelerations of low engine.

3. Reduction of warm up: By offering more ball space, the C4 game limits the internal heating of the bearing itself, thus prolonging the life of the lubrication (oil film).

4. Reliability SKF Explorer: Designed for the harshest conditions, this bearing is the guarantor of a sandy that does not "force" ever.

💡 Michel's trick

"The C4 is for the engines that work hard! Do not be surprised: cold, if you move the tree by hand, you will feel a little more game than with a C3. It's quite normal! It's this game that saves your engine when everything is Burning on the track. My advice: It's the ideal turnover if you often ride in summer or on very demanding circuits for sanding. And as for the TN9 / C3, we forget the hammer! We heal the crankcase, we take out the rolling of the fee, and It must slip like dad in mom!"

🎓 Tuto: assembly and recommendations

1. Installation temperature: Heat the motor housing around 80 ° C - 90 ° C. The bearing, ideally stored in expenses, must fall to the bottom of its resistance housing.

2. Lubrication: Never turn this dry bearing to "see how it turns". The C4 game requires the presence of an oil film (XPS Gear Oil) to work properly.

3. Control: During your revisions, check that the TN9 cage does not have a traces of abnormal coloration (excessive browning), a sign of overheating due to a lack of box oil.

4. Pairing: If you climb a C4 on a tree end, try keeping the same game class on the other level of the shaft for a perfect expansion symmetry.
