Apply Silicone Gasket Material
Liquid gasket material used by Meritor:
•
Loctite FAG 3
•
Neutral Silicon, Dow Corning 768 or Rhodia
567/666
•
Three Bond 1134
•
Loctite 515
WARNING
Small amounts of acid vapor are present when
applying some gasket materials. To prevent
possible serious personal injury, make sure
there is good ventilation in the work area. If
liquid gasket material gets in your eyes, flush
eyes with water for 15 minutes. Have eyes
checked by doctor.
CAUTION
The amount of liquid gasket material applied must
not exceed 0.125 in. (3.18 mm) diameter bead. Too
much gasket material can block lubrication
passages and result in damage to component.
1. Remove all old gasket material from both surfaces.
2. Clean the surfaces where liquid gasket material will
be applied. Remove all oil, grease, dirt and moisture.
3. Thoroughly dry both surfaces.
4. Apply according to the following procedures:
•
Three Bond 1134 or Loctite 515: Apply
approximately a 0.125 inch (3.18 mm) diameter
continuous bead of liquid gasket material around one
surface.
•
Loctite FAG 3: Apply to one surface with a paint
brush.
Also apply all gasket material around edge of all
fastener holes on that surface. Figure 3.8.

5. Assemble components quickly to permit gasket
material to compress evenly between parts.
6. Tighten fasteners with required torque. See Torque
Chart, Section 6.
DUO-CONE Oil Seal:
Mount and Install
NOTE
•
Always follow correct procedures when
mounting and installing DUO-CONE oil seals.

errors made during mounting or installation of
oil seal components.

Never let oil touch Toric ring or lodging ramps
before both oil seal rings are installed in their
mounting position.
