Before the piston and connecting rod assemblies can be pulled out the cylinder head and oil pan must be pulled off. The first operation should be to look for any ridge at the upper limit of ring travel in each cylinder if any the ridge should be removed by the use of a ridge reamer so as not to cause the breaking of the piston. Finally after removing the ridges, fix the engine in such a way that the crank shaft is in up position. Using feeler gauges, it is necessary to check the connecting rod end play, which has to be in a certain range; if it is out of this range, new connecting rods may be needed. Paint the connecting rods and caps in order to differentiate between them, then remove the connecting rod cap screw and the cap where you will find the bearing insert, be careful not to drop it. Remove the connecting rod and piston assembly out through the top of the engines with a wooden dowel and perform the above in each cylinder. After that, screw the caps of the connecting rods and both bearing inserts back in, while retaining the old inserts for the purpose of preserving the surfaces. In piston ring installation ensure that the ring end gaps and the piston ring side clearance are in order. Place the rings on the pistons with the compression ring at the top then the scavenge ring above it and the oil control ring at the bottom. Before fitting of the piston and connecting rod clean the cylinder walls and give a edge cutting to it. The new bearing inserts are installed without any lubrication and it is posted up in the correct position with correct gap of the piston rings. Oil the piston as well as the rings before putting into the cylinder with the arrow situated at the front side of the engine. Some of the things that should be done include: examining the connecting rod bearing oil clearance by the aid of Plastigage while at the same time making sure that the surfaces where the checking is to be done have no oil on them. If the clearance is other than that specified, then check for bearing size and journal diameter. After confirming the clearance, the grease should be applied to the bearing faces, the new rod cap and bolts should be put back then tightened to the exact torque. Follow the same process for the other assemblies always making sure they are clean and are in the right orientation. Last but not the least; rotate the crankshaft with your fingers, thus check for binding or anything by way of ill-tolerance and also to measure the connecting rod end play to see whether it still fits the engine or not.
