Gearbox shim -PIAGGIO- Vespa PX (1984-) EFL, T5 125cc, PK, V50, PV125, ET3 -

The axial spacing of the gear wheels is essential for a clean shifting.
The clearance given by Piaggio is 0,15-0,40mm. It is determined with a feeler gauge between the gear wheel and the shoulder ring.

NOTE: Unfortunately, Piaggio seems to use more than one supplier for the production of the shoulder rings. We receive again and again deliveries with not exactly dimensionally accurate goods.
Therefore a shoulder ring declared with 1.00mm can have a real dimension of 1.15mm.
We kindly ask you to consider this during assembly.

TIP: In order to be able to carry out the important spacing of the gear wheels precisely, we ourselves exclusively use the very dimensionally accurate shoulder rings of BGM.
