TheRadiator support bracket is a specific piece of engine architecture Rotax Max. It serves as a rigid bond between the motor unit and the radiator, allowing it to remain perfectly positioned for an optimal airflow.
Designed in high strength steel, it is studied to support the weight of the liquid filled radiator as well as the important lateral forces (G) sustained in turn. Its design allows precise mounting, limiting mechanical stresses on hoses and silent-blocks.
The Sliding gear 27 teeth made of white plastic is a piece of transmission of origin manufacturer (Original Rotax Racing). This technical gear settles inside the bas-engine to ensure the synchronized connection between the crankshaft and the balancing tree (pendulum) on all the engines of the range Rotax 125 Max (Junior, Senior, Master, DD2).
Designed in high-density white technical plastic lubricated by box oil, this gear fills an essential mechanical shock absorber role. The use of the polymer makes it possible to significantly reduce the operating noise of the motor and absorb high speed transmission micro-shocks, thus protecting the movable crew of the spurious vibrations. With its 27 teeth Perfectly calibrated, it guarantees a balancing distribution timing of absolute accuracy.
The Thunder-end needle cage (often referenced under the norm Hk1010, Ref. Rotax 232460) is a small needle bearing housed in the engine housing or launcher support. It receives the end of the electric starter shaft. Its role is crucial: it allows the tree to rotate at very high speed during the start phase with a minimum of friction, while supporting the radial stresses during the haling.
Thetraining lid Rotax MAX EVO blackis a gear protection housing designed for motors Rotax from the MAX range. Made inhigh strength aluminium, it effectively protects the drive system (balance sprocket and internal gears) while ensuring excellent thermal dissipation.
