If the assemblies of the piston and the connecting rod are to be removed, then, the cylinder head as well as the oil pan have to be first detached. To determine if there are any ridges at the vicinity of the maximum travel of the ring, one can use the fingernail; if present, they should be dealt with by using the reamer because the failure to do so will lead to a breakage of the piston. As soon as the ridges are removed, rotate the engine in such manner that with crank shaft upwards. Measure the connecting rod end play with the feeler gauges and require it to be within a given range; if it goes beyond this range a set of new connecting rods might be required. Identify the connecting rods and the caps and then take out the connecting rod cap bolts and the cap but be careful not to drop the bearing insert. Extract the connecting rod and piston assembly by pushing it through the top of the engine and if there are areas where wood dowel has to be used do so for all the cylinders. Insert the connecting rod caps and bearing inserts in their respective rods; retain the old ones in the rods until it is time to fit the new ones to avoid scr former. The pistons and connecting rods are then available for inspection and then for reconditioning. When putting on new piston rings, the ring end gaps should be checked as should the piston ring side clearance. When all the piston and connecting rod assemblies are aligned with the new ring sets; installations of the top ring into the slots of the first cylinder and checking the end gap with feeler gauges. If it is a wrong gap, then modify them gently by using the filing of the ring ends. Before putting on the middle and top rings you must make sure the 'identical marks' are vertical as well, then you install them starting with the oil control ring next is the middle and top rings. Before fitting, make sure that cylinder walls are cleaned, edges of the cylinder are chamfered and the crankshaft is inserted. Remove the old upper bearing insert and clean all the bearing surfaces before fitting the new one; it should fit as required without necessitating the use of oil. Correctly position the gaps of the piston ring, the piston and rings should be lubricated and the piston ring compressor is used in the process of installation. To check the connecting rod bearing oil clearance use Plastigage and the surfaces must be free of oil. If the clearance is not according to the above values then check the bearing sizes and the journal diameter. After installation replace the excess of plastigage material with a scraper, put some thin layer of a grease on bearing surfaces and replace the rod cap with new bolts and tighten according to the prescribed torque. Follow the similar steps for other 6 assemblies, be particular about hygiene and orientation. Last but not the least, turn the crankshaft and look for bind and a visual check on the connecting rod end clearance adjustment and correcting the same if necessary.

Before installing new piston rings, you should check the ring end gaps and ensure proper side clearance.

Yes, it includes (1) piston and pin.
