These items represent the highest quality components, facilitating an engine with maximum reliability and minimal vibration. Together with the cylinder and piston, the crankshaft is the beating heart of any internal combustion engine. It is one of the hardest working components, and the conversion of the piston stroke into a rotary motion places the highest demands on both quality and attention during construction. The crankshaft should also be well balanced to reduce any unwanted vibrations and the oscillating mass kept to a minimum to support efficient delivery of the power created by the engine. The large main bearing rotates at the same speed as the engine RPM, receives lubrication from the petrol/two-stroke oil mixture and must withstand two sudden changes in the direction of the piston for every revolution of the engine. The crankshaft pin, connecting both crankshaft journals with the connecting rod, must be pressed into the cores with a certain distance from the openings in the cores. If this connection is not strong enough, the crankshaft can rotate and the crankshaft journals become misaligned and seize. To ensure that the large end bearing receives sufficient lubrication, the large end of the connecting rod should be provided with slots to facilitate this. SIP crankshafts. This brand new range of performance crankshafts is manufactured for SIP in Italy and meets all the requirements listed above. We have focused our efforts on providing the highest quality combined with proven technological features. Each crankshaft is specifically balanced to suit the stroke, connecting rod length and scooter model for which it is intended. The crankshafts available in this range can be divided into two main types. The "Premium" models are equipped with a high-end "standard" connecting rod, which means that its surface finish remains unaltered. It is equipped with lubrication grooves and holes for large and small bearings respectively. The "Performance" crankshaft models include a very high-quality connecting rod and are made more durable with an intensive polishing procedure that provides a more stable molecular structure. The smooth, polished sides of the connecting rod also help to reduce turbulence. The polished connecting rods have also been optimised with a reduction in weight. They have a gas flow profile and have been modified around the large end to improve bearing lubrication and cooling. Crankshafts for Vespa GS 160 / SS 180 models. GS 160 / SS 180 crankshaft.
