Abstract
Abstract This invention relates to a method of assemblying a piston compressor in which the crankshaft and cylinder bores have intersecting right angled axes. The piston and connecting rod assembly is provided with a universal joint therebetween and a bearing surface having a closed wall at the opposite end of the connecting rod. The piston-connecting rod assembly is initially inserted into the cylinder followed by introducing the crankshaft into the crankshaft bore. By utilizing the piston-connecting rod universal joint the connecting rod bearing can be maneuvered into a position for placing the bearing on the crankshaft. A bushing is then inserted between the connecting rod bearing and crankshaft.
