Connecting Rod Bearing: Specifications

Connecting Rod Bearing





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/marks of its pins are painted/stamped at the positions shown in the illustration.














From the above table, select a bearing whose size is appropriate for the crankshaft pin outside the diameter. For example, if the crankshaft pin outside diameter Identification color is "yellow" and the connecting rod Identification mark is "2," select a bearing whose Identification color is "green."
If there is no identification color paint on the crankshaft, measure the pin outside diameter and select bearing appropriate for the measured value.

Rod Bearing Cap Nuts and Bolts
Then tighten the nuts alternately to a torque of 27 ± 2 Nm (20 ± 1 ft. lbs.) to install the cap properly.





Make a paint mark on the head of each nut.

CAUTION:
^ If the nut is turned less than 90 degrees, proper fastening performance may not be achieved. Be careful to tighten the nut exactly 90 degrees.
^ If the nut is overtightened (exceeding 94 degrees), loosen the nut completely and then retighten it by repeating the tightening procedure from step 3.

Make a paint mark on the bolt end at a position 90 to 94 degrees from the paint mark made on the nut in the direction of tightening the nut.
Turn the nut another 90 to 94 degrees and make sure that the paint marks on the nut and bolt are aligned.
