Pyrometer Installation Instruction
For Models R602, R604, R605, R606, R607,
R610, R611, R612, R624 Units
Refer to Installation Diagram
A. Thermocouple Installation:
The Thermocouple mounts into a ¼” pipe thread, or clamp style. If the exhaust
manifold is already drilled and tapped, install the thermocouple at the location. If
none is provided, make a ¾” hole in the exhaust pipe, not more than 6” below the
exhaust manifold-to-exhaust-pipe connection and weld the R680 bushing into the
exhaust pipe (note that the bushing should not be installed backwards – the
thermocouple will only install into one side of the bushing).
Dual Manifold: Install one thermocouple into each exhaust manifold or exhaust
pipe as above.
B. Leadwire Installation:
Single Manifold: The R660 leadwire assembly and the thermocouple are supplied
with screw and ring terminals for assembly convenience. Connect the longer red
leadwire to the red thermocouple wire and the shorter yellow wire to the yellow
thermocouple wire with screws and nuts provided. Cover these connections with
protective sleeves provided. Route the other end of the R660 leadwire assembly to
the pyrometer, making sure that the leadwire is clear of obstructions that might cut or
otherwise damage it. (If it should become necessary to replace any of the terminal
ends – use crimp or clamp types only – NEVER solder terminals to the wires.
Dual Manifold with Single Gauge: Run an R660 from each thermocouple to a
DPDT switch. The switch will then toggle from one engine bank to the other on the
same gauge.
C. Pyrometer Installation:
Pyrometers R605 and R607 require a 2 1/16 ” mounting hole; Pyrometer R602
requires a 2 ¾” mounting hole; Pyrometers R604, R606 and R624 require a 3”
mounting hole. Remove dampening wire(s) across the meter terminals. Mount the
pyrometer through the instrument panel or use mounting bracket at the desired
position. Connect the light wires to the existing instrument light switch (12 VDC).
Single Scale Pyrometers: R602, R604, R606, and R607:
Connect the R660 leadwire to the pyrometer, making sure that the yellow leadwire is
connected to the positive (+) terminal and the red leadwire is connected to the other
