Stronger Fan Blades Used On 1693 Truck Engines In White Autocar Trucks
Usage:
Description of Change: Some arrangements of 1693 Truck Engines in White Autocar Trucks use a 9L3994 Fan Assembly. This fan is close to the drive pulley for the air conditioner. It is possible that this can cause too much stress in the fan blades at some engine speeds and cause a blade to break off.
To correct this, a new fan with stronger blades is used. A spacer is also used to move the new fan farther away from the air conditioner pulley.
Adaptable To: The new parts, used together, are direct replacements for the former parts on all 1693 Truck Engines in White Autocar Trucks that use the 9L3994 Fan Assembly.
