Meticulously Oversize, Prevent knocking, and Piston Loss

Note the time of going oversized cylinder liner. If done carelessly turner, wall above-average subsurface piston aka tilted baseball. Symptoms can be caused knocking, vibrating and often jammed piston.
Could be so because when the piston heat and expand, narrow gap makes the motion of the piston so heavy and sluggish. Moreover, added the angled liner enlargement process. So there are some important requirements. The most basic, the consumer must take a replacement piston size bigger than the following standard cylinder block. Because the old piston to benchmark turner. Ask the ideal gap is made of 0.03 ~ 0.05 mm. Let baseball work twice, check the smoothness of the piston motion in the cylinder liner. The trick, wipe grease or oil on the liner and piston until dry. Then insert the piston into the liner hole while gently pressed. When the piston is pressed too forcefully, to ask for immediate turner in Huning again until smooth.

Finally, see a gap around the lip liner in which there is a piston. Through the light beam, when the beam is not around the average, do not hesitate re-polished. Because no light onset, indicating a gap between the liner is too tight piston.
