TQ-125

Linkage Installation and Adjustment

General

The linkage kit for the TQ-125 generally consists of the following parts: two rod

ends, a terminal lever, a length of threaded rod, and the associated hardware to

attach these items between the TQ-125 and the prime mover fuel control.

Linkage Compatibility

Match the actuator's direction of rotation with the fuel control's direction of

increased fuel. The TQ-125 has a counterclockwise rotation as viewed from the

shaft end for an increase fuel condition.

The linkage for diesel engine applications should be linear, and matched to the

TQ-125. The TQ-125 has a 60° shaft rotation. Carbureted engines will require a

carburetor compensating (non-linear) linkage. Incorrect linearity matching can

cause stable operation at some fuel settings but oscillation at other fuel settings.

Manually stroke the fuel control linkage from stop to stop as if the actuator were

moving it. The linkage should not bind or have play in it. Lubricate or replace

linkage or fuel control parts as required.

Make sure the actuator is capable of moving the fuel control to maximum and

minimum limits. Let the fuel control limit actuator travel. Set the linkage so the

actuator is just above minimum when the fuel control is at its minimum stop and

so the actuator is just below maximum when the fuel control is at its maximum

stop.

A positive shutdown device, such as a spring, is required to ensure shutdown

upon loss of signal to the TQ-125.

Any unauthorized modifications to or use of this equipment outside

its specified mechanical, electrical, or other operating limits may

cause personal injury and/or property damage, including damage to

the equipment. Any such unauthorized modifications: (i) constitute

"misuse" and/or "negligence" within the meaning of the product

warranty thereby excluding warranty coverage for any resulting

damage, and (ii) invalidate product certifications or listings.
