GASKET REPLACEMENT
Four gaskets seal the gauge from moisture, dirt, and debris.
Condensation may form inside the gauge if the gauge has been out
in extremely wet weather or in high humidity, or if it is used in the
cold and stored in a warm building. In this case, remove the topshell
and allow the gauge to dry. If necessary, use a hairdryer (on low
heat) to remove any built-up moisture. If moisture continues to be a
problem or debris is present inside the gauge base, the gaskets may
need replacing.
To replace the control panel gasket, loosen the four screws in the
corners of the panel, and remove the panel from the gauge topshell.
Use care in removing the panel and ribbon cable. Gently peel the
old gasket from the panel and replace with a new gasket. Replace
the connectors and the control panel.
To replace the two post gaskets and the topshell gasket, remove the
screws that hold the topshell to the gauge base. Gently peel the
gaskets away from the topshell and gauge base and replace. Tighten
topshell screws to 6 in-lb.
If replacing the post gaskets, slide them over the source rod. A light
coating of talcum powder on the inside of the new post gasket will
aid in reassembly.
