CAUTION
Please observe the following before commencing any assembly of seals:
• Protect the sealing surfaces during transport and mounting.
• Keep the seal in its original wrappings or protect it well before actual
mounting.
• The fitting of seals and gears must be carried out on clean workbenches.
• Use a protective sleeve for the sealing lip during mounting, when sliding
over threads, keyways, etc.
Action
Check the seal to ensure that:
• The seal is of the correct type (provided with cutting
edge).
• There is no damage to the sealing edge (feel with a
fingernail).
Inspect the sealing surface before mounting. If scratches
or damage are found, the seal must be replaced since it
may result in future leakage.
Lubricate the seal with grease just before fitting. (Not too
early - there is a risk of dirt and foreign particles adhering
to the seal.)
Fill 2/3 of the space between the dust tongue and sealing
lip with grease. The rubber coated external diameter must
also be greased, unless otherwise specified.
Mount the seal correctly with a mounting tool.
Never hammer directly on the seal as this may result in
leakage.
