| RE: Carter high volume pump noise? |

| I've seen the pump make a clucking noise. You can localize the noise using a stethescope on top of a pump and the front cover, versus the top of the heads. You could have some wear on the pump arm or the eccentric. Remember that there are also 2 other place where slack can be introduced. They are the pump mounting holes and the front cover holes. The problem I saw was corrected by removing the front cover and re-installing it. A trick I've seen offered on this forum is the way to install the cover. Before you tighten the mounting bolts, temporarily install the spacer on the front of the crank to center the front cover arround the crank. For the problem engine I was helping on, this fixed the noise problem. It was a recent rebuild and the front cover was not centered. By the way, since the cover was not centered on the crank, the front seal would likely have begun to leak because it was noticeably tighter on the top than the bottom. |
