Mains, 80, rods, 33...Don't forget to plasti-gauge bearings before final install. Make sure there isn't any lube on saddles or bearing backs before putting it together. Use pre-assembly lube on bearing faces and crank pins. Check that crank spins freely after each cap is torqued. If not find out why before continuing.

connecting rod caps cracked type rod-rod and caps must be kept in matched sets, recommend new bolts/nuts, spec is 32 ft lb. plus 105 degrees - torque each item to the correct torque then go back and do the degrees. these are torque to yield bolts and the procedure is very important.
