Compressive loading on a connecting rod. Compressive loading is a calculation of displacement, RPM and HP.  The RPM max power is used to calculate compressive load or the force pushing...

How important is using the proper wall thickness pin for each application? It has been a standard practice for years to keep the engines bob weight down by using light thin wall wrist...

How much Pin Clearance is needed? No matter what material the wrist pin is made of, or how thick the wall is, pins experience some amount of deformation while your engine is in use. It is the...
