The importance of cylinder wall deglazing
cannot be overemphasized. The proper cylinder finish will
provide the quickest possible break-in and greatly reduce
the possibilities of ring or piston scuffing during break-in.
The glazed cylinder wall causes rings
to "skate" on the highly polished finish and discourages
the minute amount of wear which is necessary to mate piston
rings with the bore.
The interrupted "deglazed"
finish contains minute hills and valleys which carry a film
of oil which will retard which will retard scuffing during
break of as well as produce the type of cylinder finish piston
rings can mate to very rapidly.
The finish produced by a 220-280 grit
stone is most desirable. The cross hatch pattern should intersect
at approximately a 450 angle. Too flat an angle leads to ring
spinning which prevents seating the rings.
Probably the most critical part of
the deglazing operation is the proper cleaning after deglazing.
The residue of honing, if left in the engine, will rapidly
destroy all moving parts. It is recommended that engines be
cleaned thoroughly with soap and water. Clean with soap and
water until the bore can be wiped with a clean white cloth
without soiling the cloth. After clean up, oil the area to
prevent rust formation. Waterless hand soap also serves as
an excellent cleaning agent.
WALL GLAZE BREAKERS
new Deglazer is fast, easy to use a real performer
ever under adverse condit1ions. Cylinders can be
deglazed and crosshatched in 30 to 45 seconds. Tests
made on this tool have proven satisfactory operation
