The crankshaft bearings and SPI gaskets are the most important parts of the engine, on which the reliability and smooth running of the engine depends.DOPPLER offers its customers three combinations. One combination for the original crankcase, one for the DOPPLER ER1 crankcase and one for the original crankcase (one 6303 and one 6204 bearing instead of two 6303 bearings on the original). The last combination, 6204, is more reliable on the endurance crankshaft.DOPPLER has opted for a combination of SKF C3 or C4 bearings, a polyamide cage and high quality SPI seals - 6204 C4 SKF POLYAMIDE BEARINGS (20X47X14)
