2. Inspect the block for cracks and corrosion. Check the threads in the threaded holes.
3. Inspect the cylinders for scratches and nicks.
16.4a Measure the diameter of the cylinders at the top (just below the ledge), in the middle and at the bottom parallel to the axis of the crankshaft
16.4b Measure the diameter of the cylinders using a telescopic gauge
16.4c Measure the sensor length with a micrometer
4. Measure the diameter of the cylinders at the top (just below the ledge), in the middle and at the bottom parallel to the axis of the crankshaft (16.4a, 16.4b and 16.4c).
5. Then measure the diameter of each cylinder in the same places across the axis of the crankshaft.
6. Check up a backlash between pistons and walls of cylinders by means of a set of probes.
7. If the cylinder walls are scratched, the cylinders become conical or oval, contact the specialists for boring and honing the cylinders.
8. If the cylinders are in order and the clearances between the cylinder walls and the pistons are correct, then all that is needed is to hone the cylinders.
