Do not trust his small size. This washer of 10x19x1,5mm is specifically dimensioned for the pinion of 11 teeth engines Rotax. His role? Provide perfect and constant support on the pinion to ensure that the pinion of the pinion on the output shaft does not move, despite the intense vibrations and torque variations.
By using a part of the manufacturer origin, you warrant that the steel has been treated to withstand compression without deforming. A poorly fixed gear or with game can damage the grooves of your output shaft, which represents expensive repair.
Perfect dimensional compatibility: With its precise dimensions (10mm interior, 19mm outside), it fits perfectly in the recess of the 11 teeth pinion, unlike a standard washer that could create a bad alignment or game.
Controlled hardness: The steel is treated not to crash under the pressure of the holding screw, thus avoiding the loosening of the pinion in the race.
Engine safety: On a Rotax Max, the transmission is the final link. A cowardled washer, it's a pinion that wears prematurely or who takes the game on the tree. Origin is the only reliability insurance.
"There is a classic mistake that I see too often at Paddock: reuse a washer that has already been tight too hard. The trick: Watch your profile washer. If it is slightly curved or marked by the imprint of the screw, take it. A washer that is not perfectly flat does not distribute the pressure evenly on the pinion. My Pro Council: Whenever you change gear or disassemble the transmission, put a new washer. It is a piece to a few cents that protects a box output tree that is worth hundreds. Do not forget a drop of brake fillet (Loctite blue) on the gear screw for total tranquility! "

Q: Can I use this washer for a pinion of 12 teeth or more ?
A: No, this reference is specifically studied for the geometry of the 11 teeth pinion. The gables of top size often use a different washer (sometimes thicker or with a specific shoulder) to compensate for the size of the pinion.
Q: How often should I change this washer ?
A: Ideally, at every disassembly of the pinion. It is designed to deform very slightly during tightening to ensure locking; It thus loses its elastic properties at dismantling.
To ensure maximum longevity to your 11 teeth sprocket, here are the items we advise you to have in your toolbox:
[Pignon Rotax 11 dents] (Check teeth wear at each handle)
[Vis de fixation de pignon] (If the thread is tired)
[Frein filet moyen] (Essential to secure editing)
