Abstract
A method for monitoring slide bearings ( ) of a crank mechanism ( ) of a piston engine is described, comprising at least one cylinder ( ) whose piston ( ) is drivably connected with a crankshaft ( ) via a connecting rod ( ) which is loaded alternatingly under tension and under pressure by the piston ( ) in the zone of a dead center of the crank mechanism ( ) depending on the cycle of the piston engine, with an operating parameter which changes on the occurrence of bearing damage being repeatedly measured and evaluated. In order to provide advantageous conditions for the method it is proposed that the piston position is measured at the dead center of the crank mechanism ( ) under pressure load of the connecting rod ( ) on the one hand and under tensile load of the connecting rod ( ) on the other hand and the difference between the piston positions for the tensile and pressure load is evaluated.
