Crankshaft MAZZUCCHELLI AMT 154 for Vespa PX 125 - 150 - PX 150 Arcob

On older engines, the crankshaft often becomes stiff and the rotating discs begin to rust. In addition, the bearing seal ring and radial seats often shrink, the connecting rods wear out and the cones and keys become defective. Crankshafts must therefore be exchanged when a major engine service is in progress.

We offer only the highest quality standard crankshafts (made in Italy) in our product range. MAZZUCCHELLI and MEC euro, both from the Milan area, have been supplying first-class and still affordable Vespa crankshafts for decades. The aesthetics, quality and port times correspond with the original PIAGGIO. In addition, the EUR MEC crankshafts have an excellent print size. MEC EUR specializes in crankshafts for classic cars and can also supply shafts for Vespa models up to 1951. These are low-volume products and are characterized by engine smoothness, excellent workmanship and a good price-performance ratio. Original mushroom-shaped, one-turn and rotating disk crankshafts were installed. Instead of a connecting rod, the older models have a brass bushing. The assignment of the models is carried out according to the manufacturer's data and PIAGGIO parts catalogs. Here, we have listed all the most important dimensions, which should simplify the selection of a crankshaft: gudgeon pin, crank pin, connecting rod length and hub. Before installation, check that the dimensions of the originally installed shaft match the new dimensions. More dimensional data on our products can be found under www.sip-scootershop.com .

Result: Perfect for an engine overhaul and suitable for fine tuning.
