I have damage to the mainshaft of my Lofrans Electric Windlass. I have removed the gypsy and inner clutch cons as well as the rope drum and access plate on the port-side. I thought that the shaft would then simply slide out but the main-gear has a convex gear that fits snugly over the worm-drive and this prevents extraction. I think that I have to pull the worm-drive out but it is pressed into place and I can see no method of attaching a puller to it.

Have you taken off the circlips from the shaft?

I agree with John that it should come out easily and that there is no requirement to remove the worm gear.
