yvonne; review this, I will follow with details.

Dale G. Basgall yvonne; nut 1 needs to be removed, the bolt head 12 is a 9/16" and use a box end wrench on it. Do not try to rotate the bolt head with the wrench it is threaded into the aluminum collar. Take a deep 9/16" socket with a long extension and rotate the nut off while holding the bolt from turning. The other bolt is the same but in the other collar. Do not turn the bolts until the nuts are off. Remove them and then there is one more bolt to remove 7.

The pump will then slide off after removing it's mounting bolts into the steel frame and the oil lines.
