Stuck Woodruff Key


Recommended Posts

Most of the time they will come loose by tapping between the key and shaft with a chisel. Or some times tapping down on the ends of the key with a flat punch. I would put some PB Blaster on it first and the vibrating of the hitting should penetrate it down into the slot. hope it helps and good luck

Been doing the PB blaster and taping with a chisle and not budging it off and on for about 2 hours, will put the old impeller back on try the the tap technique.

Thanks.

Got it finally. Dremel tool, cut length wise (up and down) and then tapped in on the sides and it broke free. Now to replace the upper seals, put the new gaskets and impeller on and I should be good to until the next beast rears its head.
