The saab freewheel is very different than the Bendix drive. The freewheel transfers all power through the rollers against the smooth outer ring. If the outer ring tries to rotate faster the rollers are pushed back down the slope and thus disengaging. The is no cogs in the freewheel that engage during normal operation. The cogs that you see on the outer ring are only engage when you lockout the freewheel using the lever under the dash. The rollers cannot jam in engaged position and tranfer power back to the engine but may slip when trying to engage if a small ridge is formed on the slope in the groove. The freewheel can be reconditioned by lightly machining the slope to remove the ridge (groove).
