Figure 8. Inspect and Lubricate O-Ring
WARNING: Replace damaged O-rings im-
mediately.
A damaged O-ring will cause
leakage of gases or fluids that
can lead to serious injury and
property damage.
D. Always clean the interior surfaces of the
clamp ring and apply a thin film of lubricant.
When opening, check lubrication of all hinge
points on the clamp ring assembly. These
include the following:
• One clamp ring pivot pin (Figure 9);
• Three clamp ring link pins (Figures 9 and
10); these pins should be lubricated at all
points along the pin, not just the front
(Figure 11).
The door-hinge bearings are oil impregnated,
sintered bronze and do not require lubrication but
should be checked at regular intervals for excessive
wear.
