Found the leak now can't get to it...

Has anyone seen this setup but with a security head instead of a nut and a washer?  Mine has a goofy thing I can't get off, its completely round, with two notches out of it.  Kind of makes replacing the seal difficult.  I will try and get a picture but anyone with experience with how to get it off please let me know!

I use a punch and a hammer. IIRC it's backward threads.

Sounds like it's supposed to use the same kind of tool as a front strut mount. Wouldn't happen to be the same size would it?

You're asking for trouble if you plan to remove that shaft without taking the lid off the pump.

I know it holds things in place inside the pump, just need to replace the o-ring.  By the way both of the threads with the safety lock are reverse.
