Service Magazine SEPD1259, 29 March 2011, "An Improved Fan Motor is Available For Certain Articulated Trucks". Disregard the existing article. Refer to the following information.

Description of Change: A new fan motor for the radiator package at the rear of the cab is now used. The new fan motor offers improved service life over earlier fan motors.

Adaptable To: A 293-6517 Gear Motor Gp for the radiator package at the rear of the cab is now used. The new gear motor incorporates a case drain. The 293-6517 Gear Motor Gp can be used as a replacement part for the earlier 240-6746 Gear Motor Gp and 320-6603 Gear Motor Gp .

The 293-6517 Gear Motor Gp is not a direct replacement to the earlier fan motors, because the 240-6746 Gear Motor Gp did not have a case drain and the orientation of the 320-6603 Gear Motor Gp which has a case drain is different.
