Remove the remaining carbon with a Scotch-Brite
cleaning pad or equivalent.
WARNING
To prevent serious eye damage wear eye
protection during this operation.
An alternative method to remove the carbon ridge is
to use a high quality steel wire wheel installed in a
drill or die grinder.
NOTE
An inferior quality wire wheel will lose steel
bristles during operation, thus causing
additional contamination.
Do not use the steel wire wheel in the piston travel
area. Operate the wheel in a circular motion to
remove the deposits.
Ridge Reamer
If required, cut the ridge from the top of the
cylinders.
Make sure ridge reamer does not gouge into the
cylinder bore or remove more metal than needed.
Mark each piston with the cylinder number.
During assembly, the piston must be installed into
the corresponding cylinder number.
