Message	install the rod cap on each rod and torque the bolts to spec. Measure the i.d. of the hole in the rod. Measure the journal diameter on the crankshaft that the rod will connect to. Subtract the crank journal diameter from the rod diameter. Divide the result by 2. The value you will get is the total clearance between the rod's i.d. and the journal's o.d. Subtract 0.0006" from this value. This will tell you the thickness of the bearing you need to use to achieve a 0.0012" bearing-journal clearance. All of the Nissan bearing grades are listed in the EM section of the FSM. Example: Crankshaft journal diameter: 1.9671" ConRod big end diameter: 2.0866" 2.0866 - 1.9761 = 0.1195 0.1195 / 2 = 0.05975 0.005975 - 0.0006" = 0.05915" According to the FSM, the bearing grade you will need to use in this example is grade #2 (0.0590 - 0.0591"). You will need to do this for each conrod and journal and then order the appropriate bearings. [ ashspecz.com ] [ agpowers@bellsouth.net ] Enthusiasts soon understand each other. --W. Irving.
