It is necessary and essential to clean the surface to
be sealed in order to achieve excellent tight seal.
Apply sealing LOCTITE 5205 on the box in order to
form a kerbstone of a few mm. Diameter.
It must be uniform (no crumbs), with no air blisters,
thinner or irregular zones.
Any eventual imperfection shall be correct as soon
as possible.
Avoid using material in excess to seal the joint. Too
much sealing material would drop out on both sides
of the joint and obstruct lubricant passages.
After having completed seal application, the joints
must be immediately assembled (10
− 20 minutes
time).
!
Before assembly, always check that the threads of the
ports and of the screws have no evidence of tear and
wear nor dirt.
