Leaking sealing faces can mostly be traced back to incorrect
assembly of seals and gaskets.
n Before assembling a new seal or gasket make sure that the
sealing surface is free of pitting, flutes, corrosion or other
damage.
n Inappropriately stored or handled seals (e.g. hanging from
hooks or nails) must under no circumstances be used.
n Install seals and gaskets only with sealing compound, grease
or oil, if this is specifically specified in the repair instructions.
n If necessary remove any old sealing compound before assem-
bling. For this purpose do not use any tools that could damage
the sealing surfaces.
n Sealing compound must be applied thin and evenly on the cor-
responding surfaces; take care that the compound does not
enter into oil galleries or blind threaded bores.
n Examine the contact faces for scratches and burrs, remove
these with a fine file or an oilstone; take care that no grinding
dust and dirt enters into tapped bores or enclosed components.
n Blow out lines, ducts and gaps with compressed air, replace
any O-rings and seals that have been dislodged by the com-
pressed air.
1. Lubricate sealing lips (2) with clean grease; in case of double
seals fill the space between the sealing lips with a generous
amount of grease.
2. Slide the seal over the shaft, with the lip facing towards the
fluid to be sealed.
NOTICE!
Use an assembly sleeve.
If possible, use an assembly sleeve (1) to
protect the lip from being damaged by
sharp edges, threads or splines. If no
assembly sleeve is available, you should use
a plastic tube or adhesive tape to prevent the
sealing lip from being damaged.
3. Lubricate the outer rim of the seal (3) and press it flat on the
housing seat.
