Connecting Rod Bearing: Service and Repair

REPLACEMENT
Refer to the illustration for the removal procedure.
When the connecting rod bearings need replacing, select and install a proper bearing by the following procedure.





1. Measure the crankshaft pin diameter and confirm its classification from the following table. In the case of a crankshaft supplied as a service part, identification colors of its pins are painted at the positions shown in the illustration.





2. The connecting rod bearing identification mark is stamped at the position shown in the illustration. Connecting rod I.D. is 48.000 - 48.015 mm (1.8900 - 1.8904 inch).





3. Select a proper bearing from the table on the basis of the identification data confirmed under steps 1 and 2.

Example: If the measured value of a crankshaft pin outer diameter is between 44.995 and 45.000 mm (1.7715 and 1.7717 inch), the pin is classified as "1" in the table. In case the crankshaft is also replaced by a spare part, check the identification colors of the pins painted on the new crankshaft. If the color is yellow, for example, the pin is classified as "1". In the above cases, select the connecting rod bearing having identification mark "1".
