I am putting new pins and bushings in my T190 at the bobtach and tilt cylinders. I got them all out without too much challenge, cleaned everything up and I'm now putting the new ones in. Well, as you might guess, three of the four tapered pins went in and tightened up just fine. But, now the tapered pin on the left side at the bottom of the boom arm will not tighten. This is the one that slides into the bobtach elongated hole and has no access to the other end. I used a vise grip on the bolt head and pulled it out into the taper as I turned it. This worked up to about 1/2 inch from the pin seating, but then it just spun. I'm sure I got grease on the tapered surface, so maybe I'll need to take it apart, be more careful with the grease, and start over. But before I do that, does anyone have any ideas on how I might get this pin to seat and not turn with the bolt?
