Moderator DirtyDT Posted May 9, 2014 Author Moderator Share Posted May 9, 2014 The very top part - the small centre part I have cut off - was. The rest is smooth down to the end of the crank and there is a small lip part way down. Too small to get a slide puller to grip it. Nothing was screwed into the thread as this was for the puller to be threaded into it to remove it. The remaining smooth bore, and the fact that it slightly widens at the lip about 15mm in, is why I was thinking of threading it and putting a long bolt through it to push against the crank. I would get the same effect if I welded a nut to the end of remaining coil. Probing inside it I can feel where the Woodruff key is and if I turn it on its side and fill the hole with plusgas it leaked out at various points where it joins the crank. I can say with 100% certainty that it is a push fit with a Woodruff key to stop it spinning. I haven't attempted to pop it off for a while but I am now tempted just to get it off anyhow - with the exception of damaging the crankcase as this has the engine number on it.

neversaydie Posted May 9, 2014 Share Posted May 9, 2014 I can only suggest threading it and using a high tensile hex head bolt as the jacking screw, put it under tension and soak with plus gas, tap the head of the bolt with hammer, heat the bolt head and le the heat transfer through to the tapered surfaces, more tension. Repeat until successful Link to comment Share on other sites More sharing options...
