Description of Change: A new pyrometer and instrument mounting group is available for the above engines. The new pyrometer improves reliability.
Adaptable To: The new 114-2410 Pyrometer and 140-9679 Instrument Mounting Group is available for the above engines back to first production.
NOTE: The new 140-9679 Instrument Mounting Group provides a new 140-2975 Bracket and additional hardware that allows the Engine Information System (EIS) panel to be mounted in any of three positions.
Installation Of The 114-2410 Pyrometer
NOTE: When installing a new 114-2410 Pyrometer it is optional to modify the old harness or purchase a new one. If installing a new harness see the chart for the new pyrometer gauge groups. The new pyrometer gauge groups list the hardware needed to retrofit the new Pyrometer.
The consist of the three pyrometer gauge groups are serviceable and identical except for a harness assembly that is specific to a G3508, G3512 or G3516 Engine.
NOTE: When modifying the existing harness assembly the 140-9680 Gauge group must be ordered. The 140-9680 Gauge Group provides all the necessary hardware to modify the existing harness assembly. The following modifications must be made to an existing harness assembly for compatibility with the instrument panel mounted 18 channel electronic temperature scanner:
1. Locate a cutoff length of 1250 mm (49.0 in) of cable length to extend from the harness assembly to the instrument panel connector.
2. Before cutting, add new labels to each cable with its respective identification letter (A-S) just below the cutoff length.
3. Where necessary, splice the stripped wire ends on to the shorter leads extending them to the cutoff length of 1250 mm (49.0 in). Attach red to red and yellow to yellow using 7X-1067 and 7X-1068 Connectors. Protect individual spliced cables with 200 mm (8.0 in) of 115-8525 Heat Shrink Tubing. Label the end of each spliced cable with its respective identification letter.
4. Trim 10 mm (.4 in) of red and yellow insulation from each wire end and crimp on the 8T-8730 Socket.
5. Assemble each crimped wire end into the 8T-9834 40-Pin Connector Plug Assembly and the 6I-4348 40-Pin Boot.
6. Neatly dress the loose harness wires with 3S-2093 Nylon Strap.
The following steps prepare the existing box assembly to be compatible with the new 114-2410 Pyrometer
1. Remove the old pyrometer and the 18 position switch. Install the hole plugs provided.

2. Drill a 30.5 mm (1.20 in) (C) hole to relocate the red emergency stop push switch (2).
3. Modify the panel bottom to accept the pyrometer harness connector (3).
4. Cut a square in the box for the pyrometer (1).
Installation Of The 140-9679 Instrument Mounting Group
NOTE: If the EIS Panel is remounted, the new 114-2410 Pyrometer MUST be installed to obtain the necessary flexibility. As explained above, a new harness assembly must be installed or the existing harness assembly must be modified. The 140-9680, 140-9681, 140-9682 and 140-9683 Gauge Groups provide the hardware for the 140-9679 Instrument Mounting Group. The 140-9679 Instrument Mounting Group provides the hardware for remounting the EIS panel.

1. Bore six new 3/8Diameter mounting holes (4) in the bracket Assembly. See Illustration 3.
2. Remove and discard the old lower mounting fixtures.
3. Install the bracket assembly in the new location.
Installation Of The Pressure Lines
The following table lists quantities of additional required hardware needed to retrofit various pressure gauge assemblies to the remounted panel.
Illustration 4. Pressure gauge conversion hardware. The above table lists quantities of additional required hardware needed to retrofit various pressure gauge assemblies to the remounted panel.
NOTE: Since the instrument panel is subject to new positioning, see Illustration 4 for the quantities of additional hardware needed to retrofit the various pressure gauge assemblies to the remounted panel.
Illustration 5. View of the upper support bracket that holds the tube assemblies running to the mounting bracket. (5) 7.5 mm (.30 in) (B) hole.
1. Drill a 7.5 mm (.30 in) (B) hole (5) on the upper support bracket to hold the tube assemblies that will run to the mounting bracket. See Illustration 5.
Illustration 6. View of new lines and hoses, mounting clamps and fittings.
2. Install the new 140-2975 Support Bracket to the cam cover plates. See Illustration 6.
3. Install the new lines, hoses, mounting clamps and fittings. See Illustration 6.
NOTE: When ordering the gauge groups, a four page chart will be shipped loose with the parts as a guide for the above procedures.
