Honing can be carried out independently, using special tools, but it is recommended to do this in the workshop.
Attention: If you do not have the necessary tools, contact an auto repair shop.
Before honing the cylinders, install the main bearing caps and tighten their bolts to the correct torque.
There are two types of hone - flexible, bottle brush type, and hone with spring-loaded heads.
Hone with spring loaded heads
A less experienced mechanic will probably find it easier to work with a flexible hone. In addition, you will need kerosene or special oil, rags and an electric drill. Proceed as follows.
Install the hone on the drill, squeeze the heads and push them into the first cylinder.
Lubricate the cylinder generously with honing oil, turn on the drill and move the honing tool up and down in the cylinder at a speed that will allow fine hatching on the walls. Ideally, hatch lines should intersect at an angle of approximately 60°. Make sure you use enough lube and don't remove more metal than absolutely necessary.
Do not remove the hone from the cylinder while it is rotating. Unplug the drill and keep moving the hone up and down until it stops, then squeeze the heads and pull out the hone. If you are using a flexible hone, stop the drill, then remove the hone from the cylinder by turning it in the direction of rotation.
The cylinder is considered finished if the corresponding piston under its own weight descends into the engine cylinder without jamming and jamming.
Wipe off the oil from the cylinder walls and repeat the procedure on the remaining cylinders.
After honing, make a bevel on the top edge of the cylinder using a small file so that the rings do not get stuck when the piston is installed. Be very careful not to damage the cylinder walls with the end of the file.
Wash the engine block thoroughly with warm soapy water.
Attention: The cylinder is considered clean when after running a white cloth moistened with clean engine oil along its wall, the cloth remains clean.
Rinse the block with clean water to remove any traces of abrasive material, dry it and coat all machined surfaces with anti-corrosion oil. Keep clean until assembly.
