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 cloth-
ing. The flash point of P-D-680 is 100° to 138°F (38° to
59°C).
Death or serious injury could occur if compressed air is
directed against the skin.
Do not use compressed air for
cleaning or drying unless the pressure is/has been reduced
to 30 psi (2.06 bar) or less. When working with com-
pressed air always use chip guards, eye protection, and other
personal protective equipment.
Clean cylinder seats in crankcase (2) with dry cleaning solvent and dry with compressed air.
Check that cylinder seats are smooth and flat.
Clean cylinder thoroughly with dry cleaning solvent. Dry with compressed air. Inspect for

If severely damaged or warped, replace with new cylinder
and piston.
NOTE
For piston replacement instructions refer to paragraph 5-12.
Inspect cylinder for cracks.
Inspect for scoring, glazing, or a ridge on the upper portion of inner
