Abstract
A crankcase assembly for the engine of a portable tool such as chain saw or the like is disclosed. A plastic crankcase is connected to the cylinder of the engine and an annular insulating member is mounted between the cylinder and the crankcase. The annular insulating member is made of a firm temperature-resistant plastic thereby protecting the crankcase from the temperature developed in the cylinder during the operation of the engine.
