All, Thanks for all of your gracious feedback, approaches, and experiences.
Checked to see if there were multiple set screws, etc. everything looks good from that standpoint. Removal continues to be an issue. I left the puller on the coupler with pressure. Put some penetrating oil in the set screw holes and shaft entry, taped Over holes, and rotated shaft. Said an “our father” Prayer and left for a day. I’ll be back at the boat tomorrow. Next consideration will be cutting and replacing shaft and coupler :(. Launch is approaching fast with access to marinas now open... Wanna go sailing :). /John > On May 20, 2020, at 9:24 AM, Bill Coleman <colt...@gmail.com> wrote: > > > Also, sometimes there is a set screw on top of the set screw for those who > like a belt and suspenders approach. > > Bill Coleman > > From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Paul > Fountain via CnC-List > Sent: Tuesday, May 19, 2020 7:49 PM > To: cnc-list@cnc-list.com > Cc: Paul Fountain; John Christopher > Subject: Re: Stus-List Coupler removal to install Dripless Shaft Seal > > John, > > Done this twice, and it’s getting done now, the first time, used a socket > aligned with the prop shaft and bought some Grade8 bolts long enough to go > then the coupling halves, and kept evenly tightening them to press the shaft > out ... every time the set screw hole got to the top we added penetrating > oil.
