Ball bearing -BGM PRO (Made in Italy)- Rear wheel Lambretta series 1-3

Rear wheel bearing from bgm PRO for Lambretta engines from series 1 to 3.
The special bearing manufactured exclusively for the Lambretta comes with a pre-assembled oil seal.
There is no need to fit the shaft seal ring with the BGM bearing, the high-quality sealing ring (NBR) is already fitted.
The shaft seal ring with the standard dimensions of the Li-Family with 32x45x6 mm is used.

The bearing clearance is adapted to the mounting characteristics of Lambretta engines. When fully assembled, it is still sufficiently large without the bearing running too tightly. The high-quality sealing in combination with the precise tolerancing of the bearing clearance creates a solid basis for a very long service life.

MOUNTING
To mount the bearing, heat the motor housing (hot air gun) and cool the bearing (icebox or ice spray).

The permissible torque must be observed when subsequently fitting the end shield.
Due to their design, the slender M6 stud bolts tend to tilt outwards if the tightening torque is too high, which can damage the motor housing.
A guide value of 4.7 - 5.2 Nm is specified for the four stud bolts.
