[NSRCA-discussion] OS 120 Ax bearing replacement

[Bob Richards]

Try paint stripper. There used to be a product called ZBest engine cleaner, which was nothing more than repackaged paint stripper. This is the gelled type of stripper that contains methylene chloride.  It will remove all the varnish and goo in a few minutes.

  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!
