Abstract
PURPOSE: To accurately measure the wear of crank shaft supported with crush type main bearing, by enabling to measure the mounting size before and after the use of engine without removing the bearing case.
CONSTITUTION: In case of the cap type main bearing, the bearing cover 3 is provided with the vertical though-hole 3' reaching the bearing surface, and the measuring unit 7 such as dial gauge is fitted to the hole. Further, in case of measurement, the thickness To of the lower metal 4 is measured before assembling. Next, before the use of engine, the size Lo fitted is measured with the measuring unit 7, and the hole 3' is choked by removing it after measurement. After the use of engine, the size L1 is measured again with the measuring unit 7. The thickness T1 is measured by removing the lower metal 4 from the stand plate 2. The wear of crank shaft W= (L1-Lo)-(T1-To) is obtained. Accordingly, the L size can accurately be calculated even with the use of crush metal.
