Gaggia pákové skupiny ozubená kola

It is quite common that the pinion gear on the Gaggia lever brewing group needs to be replaced. This can be from various reasons, like breaking or damaging teeth.

This pinion gear is used to lower and raise the piston shaft in the brewing group. The shaft itself is installed in between 2 sealed bearings.

Note: these shafts are made from steel so they can rust.
