Does anyone know how to disassemble the double-wide Spinlock xa clutches used for the halyards on the Hunter 25.5? Service kits that include new levers, cams, baseplates and side plates are available from Defender and Mauri Pro Sailing. But it is not clear to me how to disassemble the clutch itself. Does anyone have experience disasssembling double-wide Spinlock xa clutch?
