Cat pump noise

[boazcan]

I have a small knocking noise around the pump area that popped up yesterday.

Does anyone recognize the noise as to the possible issue? If so, what should be done?

Thanks.

No idea...sent link to thread to cat tech support:

How many hours on it? I think I'd get it apart before she damages herself and becomes a more costly repair.

2400 hrs. New seals at 1000. Nothing since.
