Yes it's finally arrived at the Sportsboat and Rib forum, the famous or should I say infamous Clevis Pin removal. For those of you who are not familiar with the PIN FROM HELL..
Most Mercruiser steering is power ram type. The end of the ram is connected to the tiller by a small clevis pin though the cast iron mould into the aluminium tiller arm and then again through the cast mould. Picture below....it's the one the right in the middle of the picture
I've nearly finished the cosmetics and repairs to my old girl and thought I would just finish off one last job before bolting all the bits back on....... WRONG..
The clevis pins have a very nasty habit of becoming welded by rust into the cast mount at the end of the ram. I soaked it on penetraing oil and rigged up a G clamp to squeeze it out. So I put small nuts either side of the pin head (top) and a piece of strong metal over the nuts, thia gave a little room for the pin to move when the G clamp lifts the pin from underneath. Wrong again.....I moved the pin as seen in the above photo by 3mm but then broke the G clamp.....
It's been suggested I heat the pin etc and cool it down quickly, so I tried that but was concerned the aluminium tiller would transnit too much heat to the seal in the transom shield so didn't get it too hot.
Any ideas?? I'm going to try to drill it out but not sure if its high tensile steel or stainless and what strength it is??
