New-Generation Guillotine Rod Seal - Rotax Evo

Maintain your engine’s performance Rotax Max Evo with this original joint seal specifically designed for sealing the guillotine rod (exhaust valve.)

This piece of new generation is rigorously identical to the original assembly carried out at the factory on the engines Rotax Here it is. It guarantees a perfect seal between the valve mechanism and the cylinder, preventing exhaust gas leaks that could impair the operation of the valve control system and the engine’s overall performance.

ℹ️ Technical note: This seal has specific dimensions of 6 mm (inner diameter) x 11 mm (outer diameter) x 3 / 4.5 mm (thickness). It is crucial for the proper functioning of the pneumatic or electronic valve system of the engines Rotax Here it is.

Description and Features

• Original Manufacturer’s Part: Manufactured by BRP-Rotax, this element certifies the quality, dimensional tolerance and perfect compatibility with your engine Rotax Max Evo.

• Vital Watertightness: The lip seal prevents pressurized exhaust gases from traveling up along the guillotine stem. A leak at this level would disrupt valve control (loss of efficiency of the pneumatic bellows or the solenoid in electronic versions) and lead to a loss of power, particularly at mid-range.

• Next-Generation Version: Designed to withstand the high temperatures and chemical stresses of the exhaust environment of racing 2-stroke engines.

• Sustainability: Although robust, this seal is a wear part subjected to high thermal and mechanical stresses. Its regular replacement is recommended during valve system servicing.

📖 Michel’s Tip

"Michel, our engine expert, recommends: Replacing this oil seal is a simple but delicate operation. When removing the old part, take care not to scratch the housing in the cylinder or the guillotine rod. When reinstalling it, make sure the seal is perfectly flat and fully seated (using a socket of the appropriate diameter, for example), and above all that it is oriented the right way (the sealing lip must face inward, toward the gas pressure side). Take this opportunity to check the condition of the guillotine rod: if it is scored or worn, the new seal will not be effective."

⚠️ Safety advice: The valve system is essential to the driving character of your Rotax Here it is. Improper assembly or a worn seal can cause the valve mechanism to break. Handle the parts with care and ensure the housing is clean before installation.
