You must remove three things before you can begin servicing the connecting rod bearing, the cylinder head,
Oil Pan and Balance Shaft Carrier Assembly. Smooth out the ridge on the cylinder's top with a ridge reamer before you remove the
Pistons so their tops are not exposed. The directional stamping for the pistons is found on the front round side near the front of the engine. With the
Crankshaft turned, use a wrench to remove each connecting rod and piston from the cylinder bore at its center. Use a permanent marker or paint to mark each connecting rod cap with the matching cylinder number and don't use a number stamp or punch to spare possible damage. Do not reuse the connecting rod bolts; carefully remove them, the rod cap and the rod, so as not to harm the fracture rod or cap. Place Special Tool 8189 onto the connecting rod to keep the crankshaft journal and broken rod surfaces safe while as you carefully guide each piston and rod assembly out of the cylinder bore. When you have completed threading the tool assembly, put back the bearing cap on the rod and go on to the next assembly before removing the piston rings. As you install the piston rings, place the compression rings so their gaps are staggered and the oil ring expander ends come together and then use the ring compressor. Lubricate the piston and rings in clean oil and after that, position the ring compressor over the piston so the rings stay in place. The front of the engine should have the directional stamp on the piston pointing at it. Spin the crankshaft until the center of the connecting rod journal is flush with the bore center and rub clean engine oil all around it. Set the upper bearing half in the connecting rod, then join Special Tool 8189 and push the piston down as you position the connecting rod. Take out the tool and after that, cover the new fasteners' threads with clean engine oil. Install the bearing half into the cap first, then install the cap and tighten by hand both bolts to 27 Nm (20 ft. lbs.), alternatively tighten another 1/4 turn without the torque wrench and repeat the same procedure with the other connecting rod. Replace the Balance Shaft Carrier Assembly, oil pan and cylinder head, making sure the connecting rod clearance is right, after using the feeler gauge to measure it.
