A device and a method for determining big end bearing and wrist pin bearing wear in a piston engine without complete disassembly of the engine. The device includes a probe rod which moves in response to the movements of the piston in a cylinder being tested. The position of the probe rod is transduced to an electrical signal which is inputted to a microcomputer. The method uses the piston position obtained via the probe rod and the crank throw angle to calculate the total amount of wear in the big end bearing and the wrist pin bearing. The results of the calculation are then sent to a display which forms part of the bearing inspection device of the present invention.
