Pinasco Motor housing with diaphragm inlet (SLAVE) for Vespa Smallframe.

Available with and without diaphragm.

The crankcase has a large central diaphragm inlet (57x48mm hole).
It is designed to accommodate the extra wide crankshafts used in Quattrini engine housings. The conventional small frame crankshafts do not fit.

The crankshaft bearings are larger and also correspond to the dimensions used in the Quattrini engine block (6205, 25x52x15mm).

Another special feature of the Pinasco engine housing is a screwed-in bearing shield for the auxiliary shaft. The diaphragm supplied by Pinasco (PN26482030 only) has a similar technology to that of the well-known Vforce models. The diaphragm is supplied by Pinasco (PN26482030 only) and can be replaced from the outside without dismantling the motor (coupling must be disconnected beforehand). The selector shaft is needle bearing and sealed.
