Recommended threadlocker and sealant
Threadlockers:
• Loctite 262
• Loctite 570 (Eaton E677)
Adhesive and Sealants:
• Dow Corning 780 (Eaton E680)
Chemical adhesives can fulfill more than one function:
1.
Thread locking, which prevents loose screws by vibration or improper torque.
2.
Screw lock and seal, preventing loose screws while ensuring that no lubricant leakage will occur through the
holes.
3.
Sealing between matching surfaces, replacing gaskets made of other materials and reducing the number of
spare parts.
Applying theadlockers onto bolts and plugs
To apply properly:
• Remove all traces of adhesive in the threaded hole.
Clean up threads with a tap and remove cutting ships
with compressed air.
• Clean the screw and its hole with alcohol. Wait for the
alcohol to dry on the screw and apply compressed air into
the hole to dry it completely.
• Apply adhesive (threadlocker) on the screw thread in the
central area that will be housed into the threaded hole,
covering 3 or 4 fully continuous fillets to ensure that no
leakage will occur.
Applying sealant onto the matching surfaces
• The surfaces that will receive the application of sealant
or adhesive must be perfectly clean and free of oil or
oxidation and must not contain particles that could damage
the seal. Thoroughly clean signs of old sealant and dirt
from surfaces.
•
When recommended, apply sealant onto the bolt and plug
contact surface with the transmission case or covers.
•
On the contact surface of transmission cases, apply a
continuous sealant string along the surface and around
the capscrew holes and dowel pins.
• Dow Corning 780 sealant cannot remain exposed to the
air for more than 15 minutes; perform parts assembly
within this time.
WARNING!
Always use safety glasses and
hearing protection when using compressed air.
