ReferenceSpecial Instruction, REHS4743, "Installation of the 346-1467 Mounting Kit "

Over time, the O-rings that help isolate the electronic portions of the actuators are deteriorated by high temperatures. The deterioration of the O-rings enable vibration to affect the performance of the actuators.

The new 346-1467 Mounting Kit is available for replacement of the mounting hardware for the electronic portions of the actuators. The kit is for use with the following components:

• 313-6079 Throttle

• 304-9395 Bypass Actuator and Mounting Gp

• 304-9396 Actuator Gp

• 304-9398 Actuator

For installation instructions, refer to the Special Instruction that is referenced above.
