Mark a position on the exhaust
manifold to locate the pyrometer
sensor. Stuff a small shop towel
or rag four to five inches into the
exhaust manifold through the
turbo mounting flange to prevent
chips from entering the manifold
while drilling and tapping.
Drill through the manifold at
the location previously marked.
Use a
7 ⁄
16
” drill, keeping the drill
perpendicular to the manifold
surface.
Tap the drilled hole with a 1 ⁄
4
” NPT
pipe tap. check the thread depth
as you tap by periodically removing
the tap and screwing the sensor
fitting into the tapped hole. The
sensor should thread in three to
three-and-a-half turns hand-tight.
Remove as many loose chips as
possible from the exhaust manifold
using a shop vacuum, small brush,
or fingers. Remove the rag using
a welding rod or coat hanger bent
into a hook.
CAuTIOn: Make sure exhaust
manifold is free of foreign
matter prior to reinstallation
of the turbo!
Install the sensor in the manifold.
Anti-seize on the threads is
recommended. Inspect the gaskets
for the oil drain and the turbine
inlet and replace if necessary.
Reinstall the turbo following factory
service recommendations.
TURBINE OUTLET TEMPERATURE:
Locate a position in the turbine
outlet pipe that is accessible with
a drill. Drill a
5 ⁄
16
” hole in the pipe.
Weld the 1 ⁄
4
” NPT bung provided to
the pipe centered over the hole.
Install the pyrometer sensor into
the bung.
Cummins B5.9L/C8.3L diesel
with factory turbo: TURBINE
INLET TEMPERATURE: The
cummins engines use a divided
exhaust manifold and turbo.
The pyrometer sensor must
be installed to sample exhaust
temperature in one of the two
exhaust passages. Typically the
exhaust temperature will not differ
appreciably between the two
passages.
Select the location that will simplify
the routing of the sensor wiring.
Disconnect both the compressor
inlet and outlet hose joint
connections. Loosen the V-band
at the turbo outlet, the four bolts
and nuts at the turbine inlet and
the two bolts in the oil drain flange.
Remove the turbo from the engine.
Mark a position on the exhaust
manifold to locate the pyrometer
sensor. (See Figure 2). Stuff a
small shop towel or rag four to five
inches into the selected exhaust
manifold passage through the
turbo mounting flange, to prevent
chips from entering the manifold
while drilling and tapping.
Drill through the manifold at
the location previously marked.
Use a
7 ⁄
16
” drill, keeping the drill
perpendicular to the manifold
surface.
