Hello My Friend , Although I cant help with the piston buttons , the bearings should be available from WWW.BOCABEARINGS.COM . Could the piston buttons from a newer one fit ???

I don't think the wrist pin pads are sold separately. They are supplied with the wrist pin.

The bearings are a standard size (6901) and available from many sources.

I have a bunch of old OS engines....I will look and see what I can find for you, also have enya, asp, and some others, oh and one as new in box os .40(i think) control line engine it is new in box with paperwork, but most likely 30+yrs old.
Can you take a pic of the parts you are needing?
I agree with the boca bearing thing, as long as you get inner and outer diameters and thickness right you should be fine, I know for electric motors I have ordered 10 bearings cheaper by ordering by dimensions rather then telling them what they are for.
You may want to contact OS and ask them what engine parts are interchangeable for that engine.

The parts listing for the Surpass 26 is here:


The manual is downloadable from this page:


The pads are sold with the piston pin, which is still available from OS. You can order part # OSMG7656 from your local hobby shop or get it at Tower.


The bearings are available from Boca Bearing for $11.88 for the pair.

You can get bearings from www.rc-bearings.com cheaper than Boca. And the service is outstanding.
