- Mounting Tuto: Expert Precautions
Mounting a hub seems simple, but it is a piece that undergoes important constraints. Here's how to do it in the rules of art:
Mounting steps
-
Cleaning the axle: Before putting the hub, perfectly clean the axle with a clean cloth. Check that there is no burr or deep scratch.
-
Light lubrication: Apply a very fine lithium grease film to the axle to prevent the hub from "flu" with time (oxidation).
-
Positioning: Drag the hub to the desired position.
-
Tightening: Screw the tightening screws (hub clamping bolts) progressively. Do not block a screw completely before tightening the other. Alternate between the two for uniform pressure on the axle.
-
Wheel studs: Check that the studs are well screwed thoroughly in the hub before mounting your rim.
💡 Michel's trick
"The classic error is too much tighten the locking screws on the axle. The trick: A hub must not be tight to deform aluminum. If you tighten too much, you create a local stress on the axle, which can make it fragile. My Pro Council: Use a torque allen key if possible, or tighten 'to the' plus a quarter turn 'in contact. And above all, always check your hubs after a track output or a rear shock: a hub that has moved can have marked your axle, which will make everything future width adjustment very difficult. "
❓ FAQ SEO (Frequently Asked Questions)
Q: Is this hub compatible with all Kart brands ?
A: The 25 mm diameter is a standard in the mini / cadet categories, so yes, it will rise on any axle of 25 mm. However, the design and the offset may vary depending on the marks.
Q: Why choose an anodized aluminum hub rather than magnesium ?
A: Aluminum (this version) is ideal for mini / cadet categories because it offers a good compromise between robustness and cost. Magnesium is usually reserved for pure competition to gain weight, but it is more fragile and oxidizes faster.
