I've got an 18 year old OS 40sf. I'd like to replace the bearings but I'm having trouble removing the drive hub. It's not the standard "flat spots on the crank and hub"type. It appears to be a press fit with a split collar between the crank and hub. Can anyone help with some advise?[]
Cheers

Go to your local auto parts supply, and ask them if they have a battery terminal puller. They may have one they can loan you. Or if not, buy a cheap one. Then use it to pop your drive washer off the tapered split cone.

Tower Hobbies sells a puller for the OS 46SF.

And i have never tried this myself but have seen it done. Taking a piece of aluminum to the crank with a hammer. Myself i have one of the pullers. But i am a tool junky

Thanks a bunch guys.[)] Got her done with a coller around the hub and a 2-jaw puller. She was on tight.[:@] Now it's off to the bearing store.
