EGT Probe Installation

Look at each exhaust stack and determine the best location at which all of the EGT probes can be
mounted at the same distance down from the exhaust ports. The ideal location is 1 1/2", but ease
of installation should prevail. Drill a 13/64" diameter hole in each exhaust stack. Insert the probe
and tighten the hose clamp. As the hose clamp is heated and cooled, it will become loose as it
conforms to the exhaust stack. After the first 10 hours of operation, each hose clamp should be
retightened.
IMPORTANT NOTE: For Cessna 210's or any aircraft using a slip joint in the exhaust system,
install the EGT probes ABOVE OR BELOW THE SLIP JOINT. Installing a EGT probe in the
slip joint can damage the probe.

CHT Probe Installation

A single CHT probe should be placed on the hottest cylinder. In a 6-cylinder engine this would be
one of the center cylinders. On a 4-cylinder engine this would be one of the back cylinders.
If a second CHT probe is to be installed it should be placed on one of the front unobstructed
cylinders. This will allow the UBG-16 to detect shock-cooling automatically.
Most engines have a port just below the lower spark plug for the CHT probe. If your engine has a
primary CHT probe in one of the cylinders, do not remove it. The UBG-16 is not STC'd as a
primary replacement instrument. Select another cylinder for your probe. If you're putting a
CHT probe on every cylinder use our P-102 Gasket CHT Probe for your primary cylinder.

TIT Probe Installation

If you currently have a TIT gauge mounted in the aircraft it may be a primary engine instrument.
If this is the case you will need to install a secondary TIT probe. The TIT probe should be in-
stalled on the inlet of the Turbo-charger one to two inches before the Turbo-charger flange. Drill
a 13/64" diameter hole in the exhaust stack. Insert the probe and tighten the hose clamp. As the
hose clamp is heated and cooled, it will become loose as it conforms to the exhaust stack. After the
first 10 hours of operation, each hose clamp should be retightened.

Sometimes finding a location for a secondary oil temperature probe can be a problem. The P-120,
P-100, P-111, P-112, P-114 and P-128 are all sealed probes appropriate for measuring oil tem-
perature. See the "Probes" section of the price sheet for dimension information.
