Special rear wheel bearing from BGM PRO for the Lambretta motors of series 1 to 3. The special bearing made only for the Lambretta has an integrated shaft seal. The assembly of the shaft sealing ring is not necessary with the BGM bearing, the high quality sealing ring (NBR) is already assembled. The internal clearance is adapted to the assembly characteristics of the Lambretta motors. When fully assembled, it is still sufficiently large without the bearing running too tight. The high-quality seal combined with the exact tolerance of the bearing clearance create the solid basis for a very long service life. ASSEMBLY To assemble the bearing, heat the motor housing (hot air gun) and cool the bearing (ice compartment or ice spray). As soon as the bearing is mounted and has heated up with the hot motor housing, the main shaft can be inserted. The slightly heated inner ring of the bearing makes it easier to install a main shaft from Casa Lambretta that is much tighter than the original. During the subsequent assembly of the end shield, the permissible torque must be observed. Due to the design, the slender M6 stud bolts tilt outwards if the tightening torque is too high and can damage the motor housing. As a guideline value for the four stud bolts 4,7-5,2Nm are given.
