How to assemble and install the pistons, connecting rods, and bearing shells on BMW 2002?

Assemble the no. 1 piston to the connecting rod, ensuring the arrow on the piston crown faces forwards and the oil hole below the small end bush on the rod aligns in the same direction, with sequence numbers on the cap and rod facing to the right when viewed from the front of the engine. Push the gudgeon pin into position using finger pressure and insert two new cir clips. Install the piston rings by reversing the removal process, noting the fitting sequence and ring cross sections. Stagger the piston ring end gaps at equal points of a circle. Insert the bearing shell into the connecting rod, apply oil liberally to the bearing and piston rings, and smear some up and down the cylinder bore before fitting a piston ring compressor. Carefully insert the connecting rod into the cylinder bore to avoid scratching the surfaces, ensuring the compressor is squarely on the top of the cylinder block and the piston rings are well compressed but not tight. Use a wooden shaft of a hammer to tap the piston/rod assembly down the bore, then remove the ring compressor. Turn the crankshaft so the number 1 big-end journal is at its lowest point of travel and pull down the connecting rod onto it, ensuring the bearing shell remains in place. Fit the shell to the big-end cap, oil it, and install it, making sure the numbers on the cap and rod are adjacent while rechecking that the piston crown arrow faces the front of the engine. Install the big-end bolts and nuts, tightening them to the specified torque with the narrower diameter of the nut nearest the big-end cap. Repeat these operations for the remaining three piston/connecting rod assemblies.

Mahle Piston
11251261926
Q: How to assemble and install the pistons, connecting rods, and bearing shells on BMW 2002?
A:
Assemble the no. 1 piston to the connecting rod, ensuring the arrow on the piston crown faces forwards and the oil hole below the small end bush on the rod aligns in the same direction, with sequence numbers on the cap and rod facing to the right when viewed from the front of the engine. Push the gudgeon pin into position using finger pressure and insert two new cir clips. Install the piston rings by reversing the removal process, noting the fitting sequence and ring cross sections. Stagger the piston ring end gaps at equal points of a circle. Insert the bearing shell into the connecting rod, apply oil liberally to the bearing and piston rings, and smear some up and down the cylinder bore before fitting a piston ring compressor. Carefully insert the connecting rod into the cylinder bore to avoid scratching the surfaces, ensuring the compressor is squarely on the top of the cylinder block and the piston rings are well compressed but not tight. Use a wooden shaft of a hammer to tap the piston/rod assembly down the bore, then remove the ring compressor. Turn the crankshaft so the number 1 big-end journal is at its lowest point of travel and pull down the connecting rod onto it, ensuring the bearing shell remains in place. Fit the shell to the big-end cap, oil it, and install it, making sure the numbers on the cap and rod are adjacent while rechecking that the piston crown arrow faces the front of the engine. Install the big-end bolts and nuts, tightening them to the specified torque with the narrower diameter of the nut nearest the big-end cap. Repeat these operations for the remaining three piston/connecting rod assemblies.
