  Q: How to replace the rod bearing in an engine on Chevrolet Cobalt?

  A:

  To replace the Piston, connecting rod and bearing, it is necessary to remove the Oil Pan and the Cylinder Head. A ridge will signify if there is a ring ridge and in this case, you need to turn the Crankshaft until the Piston is at the bottom of the stroke, apply a cloth on top of it and use a ridge reamer to remove the ring ridge. Then, drive the Crankshaft to the top of stroke, remove the cloth and cutting debris, and remember to mark connecting rods and caps for assembly. Next; remove the connecting rod nuts and cap, dispose of the bolt and nuts and extract the connecting rod and Piston from engine block using (J 41742),and(J-43966-1) wash the cylinder bores with hot water and detergent or light honing and wipe the bores with engine oil and fresh, dry cotton cloth. For installation, treat the Piston, piston rings, cylinder bore, and bearing surfaces lubricate with engine oil and install the Piston back into its original bore using (J-43966-1), (J 43953), (J 41742). Gently strike the top of the Piston with a wooden end of a hammer handle, such that the struck marked on the Piston is facing the front of the engine. Squeeze hold (J 43953) against the engine block until all the Piston rings have entered the cylinder bore and that's when install the connecting rod caps to their original connecting rods aligning the previously marked numbers. Change out the connecting rod bolts and nuts tightening them to 25 nm (18 lb ft) so as to have an equal torque across the bolts and then use (J 45059), tightening nuts by an additional 100 degrees on the final pass. Check the connecting rod side clearance using a feeler gauge, for which it should fall between 0.070-0.370 mm (0.0027-0.0145 in). Lastly, mount the Cylinder Head and the Oil Pan.
