Abstract

Crankshaft is a vital component in the construction of an internal combustion engine. Over time, the crankshaft can be deflected, thereby reducing engine performance or even causing catastrophic damage. This paper describes the development of a crankshaft deflection measuring instrument in which measurements need not be removed from the engine system. Because of its ease of operation, the crankshaft deflection measurement procedure can be adopted into the Preventive Maintenance system in an effort to increase the reliability of the generating system. The design of the crankshaft deflection measuring instrument is carried out using a digital dial indicator as the main measurement tool. With the development of wireless data communication methods, measurement accuracy can be obtained. From the test results obtained that the resolution of the measuring instrument is 0.01 mm and the maximum deviation of the calibration results is 0.03 mm.
