Before one can remove the piston and connecting rod assemblies, one is required to disassemble the cylinder head, oil pans as well as oil pumps. First, look for any ridge at the top of ring travel in the cylinder, these ridges should be ground off using the Ridge reamer in order to avoid breaking of piston. When the ridges are available, align the engine in the manner that the crankshaft is up and measure the connecting rod end-play by utilizing feeler gauges to be certain it is in the range that is acceptable; if it is not within the range, then the connecting rods may have to be changed. Ensure that each connecting rod and cap is marked for distinction and then turn the connecting rod cap bolts. Withdraw the connecting rod bearing insert and bolt, and take out the connecting rod with the piston through the top of the engine. It is advisable to replace cap and insert after its use so as to cover the bearing faces for protection. Before and after piston ring installation on the piston check the ring end gaps and make sure that the piston ring side clearance is standardized properly. Slip the rings onto the pistons commencing with the oil control ring, the second or middle ring and the last or top ring; place them in the right position. Before the piston assemblies are installed, scrape the cylinder walls, and debur all edges on the same. New items of the bearing inserts should be ready to fit into the specified grooves without the need to apply lubricants, in addition the pistons ring gap should be positioned appropriately. Oil the piston and rings and then the piston ring compressor must be used to ease the putting of the assembly in the cylinder . The following checks on the connecting rod bearings are done using Plastigage: confirm the quantity of oil clearance by fitting the rod cap and tightening the bolts. Once the oil clearance has been confirmed apply the grease on the bearing faces and fit the pieces back in the same manner to the remaining assemblies while at the same time observing cleanliness and orientation of the assemblies.
