Webra 1.45 wrist pin removal

[Keith Black]

If you haven't tried this approach I think you'll be surprised how effectively the wing nut will pull the wrist pin.

  Did you try the lever tool approach?  http://www.rcuniverse.com/forum/m_2532705/mpage_2/key_wrist/tm.htm

    I've followed directions from previous posts on removing the wrist pin. In fact I removed it for a previous bearing change. Now I'm unable to remove it. I'm using one of the four millimeter bolts threaded into the pin. I've shimmed the piston against the cylinder with popsicle sticks and pulled hard. I then used a longer 4mm bolt and clamped it in a vise and pulled on the engine quite hard; at least as hard as I dare. I've scraped the carbon from the area aft of the pin. Still no luick. (Yes, the circlip is removed.)

    Anyone have any other ideas I might try?

    Thanks, Dave
