I am replacing the seals in my Hill MK4 hand pump. The area around the white circular air filter is covered with a black greasy substance that I assume is silicone grease. I am trying to find a solvent that will remove the gunk without harming any of the aluminum and brass components. Does anybody know of such a solvent?
I am really careful with cleanliness and lubrication of this pump. I bought it new and have kept it pristine and have not over done the silicon grease. I was severely disapointed to dismantle the pump and discover all the black crud inside. The stuff looks like semi liquid black grease. This is the first time it has been taken apart. I don't think I have actually used this pump enough to need a rebuild. It simply quit pumping. I assume that was because of the round white air filter being plugged. Is this normal?
Any suggestion?
Thanks in advance
