Abstract
A machine may comprise a piston; a memory; and an electronic control module. The electronic control module may be configured to obtain information identifying a previous amount of wear of the piston pin bore and information identifying a wear limit; determine a base piston pin bore wear rate; calculate an effective piston pin bore wear rate based on the base piston pin bore wear rate; determine an amount of time between a current time and a time when the previous amount of wear of the piston pin bore was calculated; and calculate a current amount of wear of the piston pin bore based on the previous amount of wear, the amount of time, and the effective piston pin bore wear rate. The electronic control module may further be configured to calculate an amount of damage to the piston pin bore based on the current amount of wear and the wear limit.
