Toric Ring Face Seal into
Hub and into Spindle
CAUTION
Install face seal halves in the same positions
where they were located prior to disassembly.
Mixing up face seal halves can cause component
damage.
The TRS Toric Ring face seal halves must be
installed in the spindle and in the hub before the hub

WARNING
Solvent cleaners can be flammable, poisonous
and cause burns. Examples of solvent cleaners
a
re carbon tetrachloride, emulsion-type cleaners
and petroleum-base cleaners. To avoid serious
personal injury when you use solvent cleaners,
you must carefully follow the manufacturer’s
instructions and these procedures:
• Wear safe eye protection.
• Wear clothing that protects your skin.
• Work in a well-ventilated area.
• Do not use gasoline, or solvents that contain
gasoline. Gasoline can explode.
• You must use hot solution tanks or alkaline
solutions correctly. Carefully follow the manu-
facturer’s instructions.
CAUTION
Check for solvent residue on all seating surfaces.
Solvents that leave a residue on the Toric Ring,
metal face seal or on housing seal seating sur-
face can cause the Toric Ring to roll into the seal,
rather than slide. Damage to the seal can result.
1. Make sure the formed seal ring, Toric Ring and
wheel hub are clean and free of any oil or other
contaminants. If required, use a solvent like iso-
propyl alcohol, that evaporates quickly, leaves no
residue, and is compatible with the Toric Ring.
CAUTION
Install the Toric Ring into the seal ring and make
sure it is flat. Do not twist the Toric Ring when
installing onto the seal ring. A twisted Toric Ring
will not seal corr
ectly
,
allo
wing leakage of lubri-
cant and pumping of debris past the ring.
Damage to components can result.
2. Install the Toric Ring onto the formed seal ring so
that it rests in the radius of the tail of the seal ring
and is not twisted. Install the Toric Ring onto the
seal ring as follows:
