Sometimes the rope seals can clamp things pretty tight. If it will turn some with a wrench on the crank bolt you could consider pulling it. Fourth gear, clutch down, go slowly, ease up the clutch. Goes without saying that anything unusual, noise or vibration and so forth, the clutch goes back down NOW.
If it is the ropes a short pull will loosen it up.
