Service Magazine SEPD0890, 28 May 2007, "A New Alternator Drive Pulley with an Improved Wear Sleeve is Used". The article is revised in order to add SMCS codes.

Description of Change: A new pulley and a new wear sleeve are used for the machines that are listed above. The new pulley has a longer wear sleeve. The longer wear sleeve will provide more contact area for the oil seal in order to prevent leakage.

Adaptable To: The 7E-4838 Pulley has been cancelled and replaced by the 300-8569 Pulley. The new 300-8569 Pulley uses a new 300-8567 Sleeve .

The new pulley is made with thicker material. The new pulley requires the use of 0S-1590 Bolts. The new pulley and the new wear sleeve use the 235-2484 Lip Type Seal .

The new 300-8567 Sleeve will only fit on the new 300-8569 Pulley. The former 053-5065 Sleeve will remain as a serviceable item for the 7E-4838 Pulley.
