• Q: How to replace the rod bearing on 2007 Chevrolet Aveo?

  A: To replace the Piston, connecting rod, and bearing, one is required to assemble the required tools: piston pin remover/installer set ( J 24086-B ), angle meter ( J 45059 ), and angular torque gage ( KM-470-B ). First, remove the Cylinder Head and manifolds for intake and exhaust, then the Oil Pan and oil suction pipe bolts to disconnect the oil suction pipe. Move the Piston to the bottom of the stroke and place a mark on the connecting rod cap for its position and remove the connecting rod cap bolts, cap, and lower connecting Rod Bearing. Then, remove the upper Piston connecting Rod Bearing and ridge ream the cylinder wall not to scratch it with sharp worn Piston rings. Depress the Piston and then apply the Piston Ring expander tool to expand and remove the Piston rings. Remove the Piston pin from the Piston and connecting rod by using the Piston pin remover/installer set (J 24086-B) and remove the Piston from the connecting rod. Align the notch of the Piston and the connecting rod to install the Piston pin guide, grease the Piston pin with clean oil, and feed it into the assembly using the Piston pin remover/installer set (J 24086-B). Choose new Piston rings, measure and adjust necessary the Piston Ring gap, and the assembly of Piston oil rings and compression rings in order. Space the oil ring gaps and apply clean engine oil to the cylinder wall and Piston Ring. Begin with a ring compressor and place a wood handle, then perform the installation of the Piston to the lower connecting rod end to avoid damaging the crankshaft journal. Mount the connecting rod cap and bearings then tighten connecting Rod Bearing cap bolts to 25 n.m (18 lb ft.) and further with the angle meter (J 45059) to an additional 30 degrees plus 15 degrees. Finally retighten the oil suction pipe and bolts to 10 n.m (89 lb in), retighten the pan and the Cylinder Head with intake and exhaust manifolds.
