Silentblock in rubber Vespa SMALLFRAME - MD RACING - Quattrini engine casing

Description

Special silent block kit for small wasp made entirely of billet ERGAL, very high quality rubber and calculated density (75 SHORE).

In order for the play of the engine block to be reduced to a minimum, it is necessary to preload the silent blocks with a greater interlocking to the block both outside and in thickness, but this would result in the non-coupling of the internal axis, making the internal pins complicated insertion of the engine block on the frame.

The specific thread in the center of the easy-to-use pins solves the problem.

Once the right and left pins have been inserted, screw the two ends using two 10mm Allen wrenches, inserting them in the special slot at the head of the pin and tighten until it stops.

In this way you are sure that the pin length is correct and above all defined.

They are supplied together with the 1mm shim kit to compensate for any differences in boring depth or to optimally center the pin.
