New Variable Timing Control Box Assemblies (Magneto Interface Boxes) Provide Increased Moisture Resistance{1552}
Usage:
G3606 (3XF),
G3608 (4WF),
G3612 (1YG),
G3616 (4CG) Engines
Description of Change: New variable timing control box assemblies are used in the variable timing gas engine ignition groups on these engines. The new variable timing control box assemblies provide improved sealing for increased resistance to moisture entry.
Adaptable To: The chart identifies the engine model, the new and former variable timing control box assemblies, and the applicable variable timing gas engine ignition groups. The new variable timing control box assemblies are direct replacements for the former variable timing control box assemblies. The former variable timing control box assemblies are canceled.
