摘要： An apparatus operable for inserting an arcuate thrust metal insert into an arcuate gap defined by a surface of a crank arm of a crankshaft and an arcuate groove formed on an end face of a bearing portion of a cylinder block, when the crankshaft is positioned on the cylinder block such that a journal formed adjacent to the crank arm of the crankshaft is fitted on an arcuate concave bearing surface of the bearing portion. The apparatus includes a device for holding the insert and positioning the insert at a circumferential position of the journal opposite to the arcuate bearing surface of the bearing portion diametrically of the journal, such that the insert is substantially concentric with the arcuate groove. The thus positioned insert is pressed by a pressing device against the crank arm, and the crankshaft is rotated by a rotating device about its axis, while the insert is forced against the crank arm, so that the insert is rotated with the crankshaft and inserted the arcuate gap, due to friction between the insert and the crank arm.
