Before indeed disassembling the pistons and the connecting rods, the cylinder heads, the oil pan, and the oil pump pick-up should also be off if they are not yet off. Feel with your nail for any ridge at the top limit of ring travel about twenty-five millimeters from the head of each cylinder. In case the ridges are because of the carbon deposits or cylinder wear, then these ridges should be made to be eliminated by the use of a reamer known as ridge before you are able to un-stick piston and connecting rod assemblies if you have to for breaking of pistons. After cutting off the cylinder ridges, right side up the engine and carefully place on its top with the crankshaft standing up. Before removing the connecting rods, rotate the crankshaft and use the feeler gauges to measure the side clearance; they should have no play. If the side clearance is over the service limit, possibility is that new connecting rods will be required. Clean the connecting rods and their caps to note code numbers, if none exists, then punch a mark using a center punch. Insert your fingers under the heads of the other connect-ing rod cap nuts and turn each one out slowly so that they can be slackened and removed by hand D tentative tightening of the number one connecting rod cap and bursting of the bearing insert should not cause it to fall out. When removing the piston and it will slide on the crankshaft journal and cylinder wall, it is advisable to fit short lengths of plastic/rubber hoses on the connecting rod cap bolts. withdraw the bearing insert and simply eject the connecting rod/piston assembly through the top of a the engine. Press down on the upper bearing surface using a wooden hammer handle. In cases with resistance, confirm that all the ridge material has been cleared off the cylinder. Follow the same process for other cylinders in the x-ray through the use of the relevant cylinder label. Reconnecting the connecting rod caps and bearing inserts to their rods, tighten only the cap nuts slightly so they do not damage bearing surfaces. Do not cut the pistons off the connecting rods.

If the clearance is incorrect, check for dirt or oil interference and recheck the journal diameter.

Corrosion suggests coolant leakage into the combustion chamber or crankcase, which must be addressed to prevent recurrence.

Slip a short length of plastic or rubber hose over each connecting rod cap bolt.

Before installing the piston and rings, the piston and rings should be lubricated with clean engine oil.

New pistons are not required during engine rebuilding as long as the pistons and cylinder walls show no significant damage or wear, and the engine block isn't rebored. However, new piston rings must always be used.

After all assemblies are installed, you should rotate the crankshaft by hand to check for any binding and check connecting rod endplay to ensure it meets specifications.

The side clearance (endplay) should be checked using feeler gauges.

Carbon deposits on the piston tops should be scraped off, and further cleaning can be done using a hand-held brass wire brush or fine emery cloth with solvent. Avoid using a wire brush mounted in a drill motor, as it may erode the soft piston material.
