Description of Change: A new pulley and a new wear sleeve are used for the engines 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.
