Dielectric GreaseDielectric Grease
Dielectric grease is a nonconductive, insulating com-
pound applied to electrical connectors. When applied
correctly, a high-quality dielectric grease displaces
debris and moisture in the connector. The proper appli-
cation of dielectric grease lls any gaps between pins
or in the connector which prevents debris and moisture
from creating corrosion of the electrical components.
Equipment damage can occur if using
low-quality, incompatible dielectric grease.
If not applied or incorrectly applied, corrosion can result
that causes rapid increase in resistance, intermittent
connections, overheating, and a variety of electrical
problems. Numerous electrical issues throughout the
machine can be avoided by the proper application and
use of dielectric grease.
Figure 5-37. Correct Application of Dielectric
Grease
To correctly apply dielectric grease:
• Apply a thin, visible, uniform coat using ONLY high-
quality dielectric grease (Dow Corning 4 or equivalent)
across the MALE connector as shown in Figure 5-37.
• Coating too thin may not ll the gaps between
pins.
• Coating too thick may prevent proper
connection or force pins or seals out. (Figure
5-38)
• Plug in the male connector.
DO NOT force connector to lock if too
much grease has been applied.
Excessive grease application does
not allow a proper connection by preventing the
plugs from locking into place, and can cause damage
to the connector seals.
