Patent ID: 8091417

Claim:
A method of determining at least an amount of correction of a bearing height of a crankshaft in an engine connected to driven shafting, the method comprising: a bearing height computing step of determining at least heights of bearings of the engine by using a transfer matrix method based on an actually measured bearing load on the bearing at a predetermined position and an actually measured crank deflection; a bearing load computing step of determining at least a computed bearing load acting on each of the bearings of the engine based on the bearing height determined in the bearing height computing step; a reference bearing load computing step of determining a reference bearing load acting on each bearing when the bearing height of each bearing of the engine is positioned on a reference plane; a load difference computing step of determining a load difference between the computed bearing load and the reference bearing load on each bearing; and an amount-of-correction determining step of comparing the load difference determined in the load difference computing step with a set range and, when the determined load difference exceeds the set range, determining a correction range of the bearing height such that the load difference falls within an allowable range.
