Before the piston and connecting rod assemblies can be removed the cylinder head and oil pan needs to be removed. Feel with a finger on the metal part for any ridges at the maximum limit of the rings travel, which are reqmired to be scraped of by a specialized tool to avoid breaking of the piston. Following removal of the ridges, position the engine in the manner where the
Crankshaft is on the upper side and measure the connecting rod end play and make sure that it falls within the standard prescribed limits. The connecting rods and caps should be marked for identification and the connecting rod cap bolts then slackened and the cap and bearing insert withdrawn without falling. Remove the connecting rod and piston assembly out through the top of the engine perform the same process as above for all cylinders. That is after removal, tighten the caps as well as the inserts to avoid further damage. During the installation of piston rings, the end gaps, as well as the orientation, should be considered and the piston rings must correspond to the pistons and cylinders. Place the oil control ring more closely to the block after the compressions rings and make sure to place the identification mark to a particular direction. It is recommended that before inserting the piston and the connective rod, the cylinder walls should be free from dirt and the crank shaft should be fitted. New bearing inserts do not need lubrication when being fitted into the engine block, align the piston ring gap appropriately, lubricate the piston and the rings and use the piston ring compressor to guide the piston into the cylinder. Correctly measuring the connecting rod bearing oil clearance should be done using the Plastigage and cleaning the surfaces before applying grease before the final tightening. So do for all pistons and connecting rods, making sure that the surfaces are very clean and that the connecting rods are correctly orientated. After installation use the starter to rotate the crankshaft to check for binding and to check the connecting rod end play and ensure that it is within the limits of tolerance. If so, it may be necessary to work with an automotive machine shop to make them.
