Rotax Tree Bearing 6005 TNH C3 25x47x12 SKF (8)

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").

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).

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 SKF 6302 TN9 / C4 bearing (15 x 42 x 13 mm) pushes the technicality even further than version C3. It keeps the high performance polyamide cage (Tn9) that reduces friction and weight, but adopts a radial internal game C4 (more important than the C3). This specification is particularly popular with the motorists for the balancing and transmission shafts subjected to very strong thermal expansions or for the motor blocks whose machining requires maximum freedom of rotation.

The Balanced rolling washer (ref. 227280) is a large diameter technical washer designed to secure the axial position of the balancing shaft bearing. Placed between the bearing and the fixing screw in the housing, it prevents any lateral displacement (translation) from the bearing during thrilling acceleration and deceleration phases, thus guaranteeing a perfect alignment of the pendulum sanding.

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 SKF 6302 TN9 / C3 Bearing (-dimensional 15 x 42 x 13 mm) is one of the most technical components of internal sanding. Its design combines a fiberglass reinforced polyamide cage (Tn9) and an increased radial internal game (C3). This specification is crucial for competition engines because it helps with very high rotational regimes while minimizing the power losses by friction.

The Right water fitting (ref. 224094) is the threaded tip that attaches directly to the motor housing to allow the cooling hose connection. Made of treated steel or brass according to the series, it ensures a passage of constant flow to the water pump. Its "right" design is standard on the majority of montages Rotax To facilitate the path of the hoses along the chassis.

Protect and lubricate the mechanical components of your karting with the Fag Arcanol Mult2 Lithium Lithium Grease, packaged in practical tube of 250 gr.

Specifically developed for the lubrication of ball, roller bearings and levels subjected to moderate to high stress, this high-quality fat guarantees optimal protection against wear and corrosion in competition or leisure environment.

The Crankshaft spy seal 28x38x7mm fpj (ref. 650480) is a high-tech component designed to seal the low engine at the crankshaft silks. His contact lip is manufactured in Teflon (PTFE), a material offering exceptional thermal resistance and an extremely low friction coefficient. This is the standard used on the engines Rotax Evo To maximize power while ensuring perfectly air seal and mixture.

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.
