The Screw FHC 5x12 (ref. 241810) is a milled head screw (six troughs) specifically used to secure the balancing shaft bearing washer in the engine crankcase. Despite its small size, it supports constant vibrations and ensures that the bearing remains perfectly in place in its slot, thus avoiding any shift in the gnat.

The Intermediate pinion pawn 6x40 (ref. 229430) is the rectified cylindrical axis on which the intermediate sprocket of the peancial sanding is rotated. With its precise dimensions of 6 mm in diameter for 40 mm long, it ensures the perfect positioning of the gears. A pion in good condition is the guarantee of a silent transmission and a regular wear of the teeth of the gears (plastic or steel).

The Spi 7x26x7 seal (ref. 230195) Provides the critical separation between the cooling circuit and the gnattern crankcase. Positioned on the water pump shaft, it ensures that the coolant remains in the engine and the box oil is not contaminated by water. Perfect sealing at this level is vital to avoid engine overheating or an oil emulsion (the famous "mayonnaise").

TheWater pump axis with turbine (ref. 226226) is the heart of the cooling system. Driven by internal sanding, this axis rotates the turbine (propeller) which propels the coolant through the cylinder and the radiator. Manufactured according to the strict tolerances of the BRP-RotaxThis set guarantees a constant, essential flow rate to maintain the temperature of your engine in its ideal performance range.

The Water pump (ref. 229470) is a small steel precision cylindrical pin. Its role is to ensure rigorous alignment between the motor housing and the water pump cover. A good alignment is crucial for the water pump shaft to be perfectly centered in its spite joints and its bearings, thus avoiding any premature wear or cooling liquid leak.

The Central crankcase (ref. 250512) is a precision piece cut in a specific material (high performance armed paper) designed to withstand hydrocarbons and internal pressure variations. It is placed between the right housing and the left crankcase. Its role is twofold: guarantee the total seal of the pump housing (for optimum pre-compression) and ensure the precise side spacing between the two carters for the proper functioning of the crankshaft and the gnat.

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.

The Wedge 8.5x15x0.50 (ref. 227480) is an adjustment technique washer. Mainly used on the axes of internal sanding (such as the water pump shaft or some intermediate axes depending on the versions), it allows the side game moving components. Its calibrated thickness of 0.50 mm Guarantees that the rooms are neither too free (vibration), nor too constrained (heating and friction).

The Adaptable "multi-motor" launcher is a Bendix type mechanism designed to provide enlarged compatibility. Although it is not a part of the manufacturer origin (OEM), it scrupulously respects the mounting ratings of the most popular motors on the market (Rotax Max Iame X30, Vortex Rok). This is the preferred choice for leisure rolling or for training, making it possible to maintain its material in perfect working order without the cost of the original room.

This protective cover (also called starter housing) is a critical safety part for all engines in the rangeRotax 125 Max(Junior, Senior, DD2). It not only protects the driver from rotating parts, but it also supports the starter launcher mechanism.
