Using glaze remover tool and electric

bore (2)

drill at low speed (350-500 rpm),

break bore glaze and produce a

crosshatch pattern on surface.

abrasives which can cause rapid engine wear and ring failure.

Using clean, dry rags, wipe away as

much of the abrasive deposits as

possible.

Using clean rags soaked with engine oil,

wipe out bore (2).

Using clean, dry rags, wipe away all

oil.

Continue to clean with clean rags until

the rags show no evidence of discolora-
