The crankshaft is the part of an engine which
translates reciprocating linear piston motion into rotation. Automobile
crankshaft failure, apart from poor maintenance culture, is caused by age and
distance covered. These attributes which caused crankshaft failure were
investigated using questionnaire administration and oral interviews of the
maintenance expert and experienced personnel
in the three selected crankshaft maintenance shops in Akure, Nigeria based on
six popular crankshaft brands. Information/data on failure rate and failure
consequence thresholds were established and served as a decision rule on the
basis at which optimal reconditioning process, replacement and interchangeability
system of the crankshaft components were identified on the occurrence of failure rate (R1) and failure consequence
(β1). Computer algorithm was
developed for the software package, using Microsoft Visual C# computer
language. The software was tested to determine their level of performance. The
results generated from the application of these systems were categorised into six scenarios whereby the
MC230 Class gave the best result. The
software will be veritable tools in predicting crankshaft failure
in automobile, manufacturing, and machine tools industries, for prompt
