(continued)
16.
Remove the push rod (212) from the plug (211).
17.
Remove the 'O'-ring (214) and the seal (213) from the
plug (211). Use a small straight-headed screwdriver to
remove the seal.
18. Wash all the parts
a.
Wash the parts in a container of kerosene (pre-
washing).
b.
Immerse the parts in a container of kerosene and
rotate the container to wash the internal surfaces of
the parts (final washing). Wipe all kerosene from the
parts with clean waste cloth.
Rust prevention
Apply rust-inhibiting agent to all parts.
Leave the parts to soak until oil and dirt become free. The
parts may be scratched if they are washed when dirty.
Washing the parts in dirty kerosene may scratch the
surfaces, impairing performance after reassembly. Make
sure that the kerosene being used does not become too
dirty.
Do not dry the parts with compressed air, as the dust and
water in the air may cause scratching or rusting of the
surfaces.
Parts may rust if they are left in the open air after washing,
impairing the valve function after it is reassembled.
