I have the original fan. A new water pump was donated. The heads of the rivets that hold the blades together hold the fan maybe 1/8" away from the face of the pump pulley. I can't remember if this gap was present with the original pump. I turned in the original pump for the core. I thought I had compared the two to make sure they were the same.
So, the question is, should there be a gap, or should the diameter of the pump fit inside the fan rivets?

My original also had a stamped pulley that was held on by the bolts and my replacement had a one piece cast pulley. I had to grind little divets where the fan rivets touch. You don't want the fan just resting on the rivets but on the flat face. | | | | | Joined: Jan 2011 Posts: 144 Shop Shark | | Shop Shark Joined: Jan 2011 Posts: 144 | Thanks. I didn't think it should be resting on the rivets. Didn't think about just ginding little divets. The rivets hit right on the edge, so it should be pretty simple.
