Replacing forestay under a Harken "0" Furling system

[joelucca]

Hi, I have a 20 year old Harkin Furler, Model "0" on my Columbia 8.7. This system has worked without fault since I had it installed 20 years ago. However, I want to replace my headstay and haven't a clue how to disassemble this unit and put it back to together. I still have the installation manual. I would love to hire a rigger to do this, but there are none in Lewes, Delaware, where my boat is docked. Any insights on this topic (including a rigger) would be appreciated.

Thanks,
Joe
