The purpose of this bulletin is to identify the oil pump spring usage for the two different pump designs.

Manufacturing of the first design oil pump springs ended December 15, 2003. Manufacturing of the second design oil pump spring began December 16, 2003

The first design oil pump springs (206) and (207) DO NOT have any identification markings. The first design springs (206) and (207) use an inner and outer spring, two springs.

The second design oil pump spring (245) is identified with tapered ends on the spring (245) as shown above. The second design spring (245) is a single spring.

When servicing either (first design or second design) oil pump body, use the new single oil pump spring (245) with tapered ends.
