: I am looking for pratical information as to what causes bore glazing and how to deal with bore glazing if it occurs in your tractors engine.
: Can any one help me ? It is my understanding that "bore glazing" is the natural result of the rings sliding up and down and "polishing" the bore over time. The usual way to deal with it is by using a "glaze breaker" which is a type of hone. I believe it uses a fine whetstone type of device, and the less expensive types can be chucked in a hand drill. There is a centrifugal/spring device that pushes the stone against the sides of the bore as it spins, and you run it up and down the cylinder a few times to rough it up. This assumes that the cylinder is in good shape, within tolerances for diameter and roundness, and that glazing is your only problem. Most likely, if you're going to tear a motor down far enough to do this, you'd go ahead and put a fresh set of rings in. Others may have more details or correct me as to the cause.
