The Husqvarna K760 crankcase assembly is available to purchase from Findasaw.com. A brief description of the crankcase assembly is as follows. Larger numbers of small two stroke engines use a sealed crankcase as a compression chamber for their fuel mixture. These are hugely common as petrol small engines for disc cutters. Both sides of the piston are used as working surfaces. The upper side is the power piston and the lower side acts as a scavenging pump. As the piston rises, it pushes out fumes which draws in fuel and air. As the piston travels downwards, the compressed fuel and air charge is pushed from the crankcase into the cylinder.
Unlike larger engines, the crankcase contains a combination of petrol and oil, and this mixture provides splash lubrication for the cylinder walls, the crankshaft and connecting rod bearings. Using a ball or roller bearings in such engines has always been more common than the oil fed plain bearings used for other engines. As these are more amenable to using this oil mist lubrication.
