[NSRCA-discussion] OS 120 Ax bearing replacement

[Grow Pattern]

John,
          You can clean the wrist pin while it is in the engine by threading a loop of Dental-floss around it and puling back and forth on each end at the same time.

Quick and easy once you have done the threading but :-)

Regards,

Eric.

  If con rod is stuck on wrist pin, you can try laying engine on it;s head, and filling piston with laquer
  thinner to help disolve goo on wrist pin.  After a days soak, it might move further.

    I don't know about that motor, but on many motors you have to remove the sleeve so you can get the piston/con rod assembly to move enough toward the back of the motor to get the con rod off the crankshaft.

      Has anyone replaced the bearings in their OS 120 Ax? What's the trick? I've done plenty of bearings but this one is different. After removing everything, including the sleeve, I can't slide the rod far enough back to get it off the crankpin. The pin boss in the piston is too narrow to allow the rod to slide far enough. If anyone has done this already I'd appreciate any insight. Thanks!
