Using a ridge reamer, it is essential to carry out the process of removing the remaining of the ridge, which is at the top part of cylinders until it is fully done as a way of preparing for the removal of the pistons. For the ridge reaming tool, the manufacturer's guidelines should be strictly followed, especially when failure to remove the ridge would lead to breaking of the piston rings when attempting to pull out the piston and connected rod. After stripping off all the cylinder wear ridges, turn the engine in such a way that the crank shaft is on the top. shift the connecting rods and the caps; if there are no marks then use a small punch to make marks on the rods and caps out of identification. Tighten all the nuts of the connecting rods half turn and then remove all the nuts and lift off the rod caps and bearing inserts to retain the bearing inserts with the corresponding caps for further examination. To prevent rod and crankshaft journal or cylinder damage, fit a short piece of plastic or rubber hose over each connecting rod cap bolt during the removal of the pistons and rods. Remove the connecting rod and piston assembly through the peak of the crankcase using a wooden maul to force the piston down through the cylinder block and then be ready to catch the connecting rod as it drops. If resistance is felt, make sure all ridge has been taken off the cylinder. The same process is to follow with the rest of the cylinders, after which the connecting rod caps and bearing inserts are to be replaced on their respective rods, with the nuts only to be tightened by the amount to be gripped by fingers while the old bearing inserts are retained on the rods to avoid injuries on the bearing surfaces.

After cleaning, use solvent to clean the piston/rod assemblies and dry them thoroughly.

If the clearance does not match, double-check the bearing inserts and crankshaft journal diameter for cleanliness.
