Use hone J5902-1 equipped with 120 grit stones. Spin hone at 300 - 400 rpm working the full length of liner a
few times to produce a criss-cross pattern having marks on a 45 deg axis.
WARNING
Dry cleaning solvent P-D-680 (safety or Stoddard’s solvent) is potentially dangerous. Avoid repeated and
prolonged breathing of vapors and skin contact with the liquid. Do not use near open flame, arcing
equipment or other ignition sources. Always wear eye protection and protective clothing. The flash point of
P-D-680 is 100 to 138 deg. F (30 to 59 deg. C).
Death or serious injury could occur is compressed air is directed against the skin. Do not use compressed
