CAUTION!
Please observe the following before commencing any assembly of seals:
• Protect the sealing surfaces during transport and 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,

Equipment, etc. Art. no. Note
Grease Oil and Grease specification on

Action Note
1. 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).
2. Inspect the sealing surface before mounting. If scratches or
damage are found, the seal must be replaced, as it may
result in future leakage.
3. Lubricate the seal with grease just before fitting. (Not too
early as there is a risk of dirt and foreign particles adhering
to the seal.)
Fill the space between the dust tongue and sealing lip to 2/
3 with grease. The rubber coated external diameter must
also be greased, unless otherwise specified.
Art. no. is specified in
Equipment on page 112.
4. Mount the seal correctly with a mounting tool.
Never hammer directly on the seal as this may result in
leakage.
