FHC 5x12 Screw of the Balancer Bearing Rotax Max (10)

Full description: a precision screw

Why use the original screw Rotax rather than a standard screw?

1. Current head (FHC): Its conical shape makes it possible to self-centered perfectly in the holding washer and not to exceed at height, avoiding any contact with the gears in motion.

2. Class 10.9 or higher steel: Unlike hardware screws, it is designed not to lie under the effect of the heat block heat.

3. Footprint Six Pans (BTR): Allows precise tightening to the torque, essential for a room inside the engine.

4. Specific dimensions: The 5mm thread and the 12mm length are calculated to provide maximum plug in the aluminum of the housing without risking or hanging.

? Michel's trick

"It's the most dangerous screw of the engine! Why? Because if it is loosen, it ends up in the teeth of the pendulum gables and it is the immediate case. My advice of old briscard: Loctite mandatory! Cleans the thread with the degreaser before putting a blue net brake drop. And beware of disassembly: the 3mm imprint is small, if you use a bad quality key, you'll round it. If it resists, heats a little crankcase to soften the old glue before forcing! "

? TUTO: Editing and safety

1. Cleaning: The tapped hole in the crankcase must be free of box oil so that the net brake can act. Use a blow gun or cotton swab with brake cleaner.

2. Pastel installation: Place the holding washer on the bearing, then show the FHC screw.

3. Tightening to the couple: Do not tighten as a deaf, the tapping is in aluminum. Firm clamping (about 5-6 nm) with net brake sufficiently enough.

4. Replacement: If the hex footprint of the screw is damaged during disassembly, does not try to reassemble it. Change the systematically, otherwise you will not be able to remove it next time without drilling!
