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

On older engines, crankshafts often become stiff and rotating discs begin to rust. Additionally, the bearing seal ring and radial seats often shrink, the connecting rods wear, and the cones and keys become defective. Crankshafts must therefore be replaced 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 EUR, both from the Milan area, have been supplying first-class yet affordable Vespa crankshafts for decades. The aesthetics, quality, and fit match those of the original PIAGGIO crankshafts. Furthermore, the EUR MEC crankshafts have an excellent press fit. MEC EUR specializes in crankshafts for classic cars and can also supply crankshafts for Vespa models up to 1951. These are low-volume products and are characterized by smooth engine operation, excellent workmanship, and a good price-performance ratio. Original mushroom-shaped crankshafts, with a full rotation and rotating disc, were installed. Instead of a connecting rod, older models have a brass bushing. Model assignments are based on manufacturer data and PIAGGIO parts catalogs. Here, we've listed all the most important dimensions that should simplify your crankshaft selection: piston pin, crank pin, connecting rod length, and hub. Before installation, check that the dimensions of the original crankshaft match the new ones. More dimensional data on our products can be found at www.sip-scootershop.com .

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