Remove the pan, oil feed pipe and deflector (if any).
If the connecting rods and big end caps do not have markings indicating their location in the cylinder head (those. cylinder numbers), mark them with a punch on each side of the cap/connecting rod joint. Note which side of the engine the marks are facing.
Unscrew the bolts of the first connecting rod large head cover and remove the cover. If the bearing shell can still be used, tie the cover with the shell.
Check the top of the cylinder bore for a wear ridge. If there is any obvious sign, carefully scrape it off with a reamer, otherwise the piston rings may get stuck in the ridge when removing the piston from the block.
Using the end of a wooden hammer handle and pressing on the bottom of the connecting rod, push the piston/connecting rod assembly up out of the cylinder. Remove the bearing shell and tape it to the connecting rod if it is suitable for use.
Remove the other three piston/connecting rod assemblies in the same manner. If necessary, rotate the crankshaft.
