Reference: Service Magazine; December 26, 1988; Page 6; "New Governor Control Cable Used" on D25C, D30C, D35C, D350C, D35HP, and D400 Trucks.
Description of Change: A new governor control cable assembly is used. The new cable assembly is resistant to high temperatures.
The reference article describes the introduction of the 7X1606 Cable Assembly as a replacement for the 3U5421 Cable Assembly. However, it has been found that on machines with 3406 Engines (D35HP, D40D, D400, and D400D), the 7X1606 Cable Assembly does not allow full governor travel.
Adaptable To: The new 9X4219 Cable Assembly is a direct replacement for the former 3U5421 and 7X1606 Cable Assemblies.
If the new cable assembly is not available:
...The 7X1606 Cable Assembly may continue to be used as a service replacement for the 3U5421 Cable Assembly on machines with 3306 Engines.
...Continue to use the 3U5421 Cable Assembly for service replacement in 3406 Engine applications.
