Protecting the counter surface
against corrosion
Under normal storage conditions the seal
counter surface should be protected against
corrosion until the machine is to be used by
coating it with a rust inhibiting medium.
The rust inhibition should last for a year
with or without packaging.
The protective coating should be soluble in
the medium which is to be sealed. Laquers or
tars should not separate out as these might
impair the sealing.
Where machines are to be transported for
long periods (overseas) or stored in
unfavorable conditions (e.g. outdoors), or
where they are not in use for long periods,
special corrosion inhibitors should be used
which form tough, pliable and wax-like films
that can be removed using neutral solvents.
The solvents should leave an oily residue.
Removal
As radial shaft seals should never be re-used,
their removal is seldom a problem as there is
no need to be careful not to damage the seal.
However, before beginning, it may be advisable
to note the direction in which the seal is
mounted so that the lip of the replacement
seal can be mounted in the same direction.
Small seals can generally be removed using a
screwdriver. The dismounting of large-size
seals is made easier if recesses have been
provided in the housing shoulder, see picture in
table 15, page 81, allowing access for a drift.
