OS Piston Pin

[michael Medlin]

Verne, sometimes the rod will get caught in varnish that forms on the wrist pin. Turn it to BDC, take an L-shaped allen wrench and position it behind the rod as close to the piston as possible, and give it a pull. Try to pull it evenly at top and bottom. You may have to spray a little penetrating oil on the wrist pin to get it to break loose. It should come out and go back in at BDC.

  Steve,
  I've got the sleeve out but I can't get the rod off the crank pin to save my life. The piston is at TDC. Troy's all wet about doing it at BDC. The groove machined in the case won't allow the rod to slide off the crank pin. I assume that when you were talking about tapping the backplate on a wood block, you were describing how to get the rear bearing out. My problem is getting the piston and rod off the crank. Just won't go. I get it about 3/4 of the way off and then it's stuck.

    Verne pull the sleeve out then the piston and rod will come out together then you can push the pin out from the other side, just done mine this morning, the Webra has the threaded pin.
