Balanced rolling washer Rotax Max (9)

Full description: why is this washer indispensable?

On an engine Rotax, the balancing tree rotates at high speed to cancel the vibrations. This washer plays several key roles:

1. Axial blocking: She acts as a stop. Without it, under the effect of heat and vibration, the bearing could "slide" in its housing housing, resulting in a misalignment of the plastic sprockets and their immediate case.

2. Distribution of pressure: Thanks to its calculated support surface, it distributes the clamping force of the screw on the outer ring of the bearing without constraining the rotation of the balls.

3. High resistance steel: Made in a steel treated against deformation, it retains its flatness even after several engine heating cycles.

4. Technical compliance: It is a security piece of origin manufacturer, indispensable to validate the conformity of your engine in competition.

? Michel's trick

"Do not make the mistake of forgetting it! It is often dismantled to take out the bearing and sometimes ends up hidden under a cloth. If you do not put it back, your rolling ride will walk from left to right in the crankcase. Result? Your sprockets of pendulum (those plastic) will work through and you will turn them into confetti in less than two towers! My advice: Check that it is not marked or 'dug' by the old screw. If it is distorted, change it, it costs anything compared to a kit of New gears!"

? TUTO: assembly and precautions

1. Mounting order: The bearing is inserted first in the crankcase, then the holding washer comes to appear against him.

2. Tightening: Use the Fillet brake (Loctite blue type) On the screw that keeps this washer. If the screw is loosen, it will fall directly into the sandy ... and there is the assured carnage.

3. Meaning: Make sure the washer is perfectly flat against the bearing before tightening.

4. Inspection: During each revision of the gnattern, check that the washer has no suspect friction traces, which would indicate a bearing that starts to turn in its housing.
