Full description: Reliability and assembly

Why use certified hardware Rotax rather than standard hardware?

1. Resistance class 8.8: This standard ensures that the screw can support the clamping stresses and thermal expansion of the motor block without lying or breaking.

2. Elzn Treatment: This specific zinc is avoiding the phenomenon of "cold welding" between screw steel and the aluminum of the housing, thus facilitating the future dismal.

3. Partial thread (FP): The smooth part of the screw allows perfect centering and a better distribution of clamping forces on the walls of the housings.

4. Quality BTR Footprint: The hollow hex is machined precisely to prevent your key from ripe, even after multiple maintenance cycles.

💡 Michel's trick

"Guys, a crankcase screw, it respects it! We do not hug themselves with a low-end key. My advice: use a torque. On the aluminum of Rotax, the couple recommended is 10 nm. If you tighten too hard, you will crack the housing thread, and there is the insured helical! A small mesh of copper fat on the thread before mounting, and your screws will never block, even after a complete season in the rain. "

🎓 TUTO: Mounting and Maintenance

1. Cleaning the thread: Before mounting, pass a blow of blower in the tapped hole to evacuate the old oil or the metal residues.

2. Manual approach: Always start screwing by hand on the first 3 or 4 turns to be sure not to engage the screw.

3. Cross clamping: For housings, always tighten the screws gradually by following a cross scheme to avoid deforming the central seal.

4. Visual control: If you see that the screw head begins to be marked or the hex footprint turns off, replace it immediately. A screw blocked with a messed footprint is a mechanical nightmare.
