Hey those gasket surfaces are hard to clean with the knock pins in there, as you're probably finding out... And you should get those good and clean to not leak including both sides of the screen. If you want to get them out, stick a close-fitting drill bit in them and then you can use your favorite pliers on them without crushing. A little heat may help too.

Removing the hollow dowels (knock pins) by lubricating first with PB Blaster (or something similar), and then use an appropriate sized EZ-out to rotate them out is also convenient. Regards, Chase

The best part about removing the knock pins is crushing them with pliers then having to wait two weeks to order them through your local Honda dealership....

I made some taper pins to push in before using grips on them.

I make my own knock pins from stainless steel tube turned down for a snug fit and correct length.

You guys are the best, not only do you provide valuable information and insight, but you make me laugh too. Thanks.

I got the darned thing out of the oil pump base but I haven't tried the one in the lower case yet. I put a bit of PBBlaster at the base of the pin, tapped it lightly for a bit, then put a hose clamp on it. I then tapped the clamp knuckle with a brass rod and a small hammer. Out it came. Who said that necessity was the mother of invention?

Now I just want to know how Loud Mouse would have done it. Ed?

Actually I don't remove either of them no matter where they stuck.
If in the case my Carb Cleaner softens them and same if in the pump body.
I then use a wire brush on the case and wire wheel on my bench motor on the pump.
I also take the pump apart and inspect the pump wheels for damage and look at the area where the side of the wheels contact the aluminum pump parts for scaring. ..................lm.

Thanks, LM. That's the best answer yet - don't remove them at all. I'll leave the one in the engine case alone.

When I cleaned up the pump housing and the filter, it appeared that the gaskets had been glued down with what I guess to be a shellac gasket compound. I think that's what was holding the pin in too. Once I cleaned the pin and the hole, the pin slides in and out freely. Was shellac gasket compound the right thing to use on the gaskets and on the pin?
