Piston assembly installation method e.g. for crankcase of combustion engine, involves having pistons and connecting rod combined by pin and led into bore having base with connecting rod in pre-mounted piston group

摘要

The method involves having pistons (13) and connecting rod (12) combined by a pin (17) and led into a bore (18) having a base (16) with connecting rod in a pre-mounted piston group (14). The connecting rod is separated from the piston with the small base connecting from the crank area (4) into the cylinder. The piston is aligned in the bore with the pin held laterally by the crank case. The piston has a snap ring (20) pre-mounted for the pin.
