Stubborn Clutch
So that OTHER season of boat work has begun and I need to work on my clutches. They seem quite old and have been slipping, with 2 of the 6 barely operational. If I can’t repair/adjust then at least I have a template as a starting point for new ones.
I digress......I plan(ned) to remove them and was eventually able to access the backing plate and screws from below. All screws are removed and it does not want to leave. The darn thing won’t budge. I scored around the edge thinking they may have used adhesive sealant as they did on the screws. Is it possible they adhered it to the cabin top with adhesive as well? Can I damage the cabin top applying too much pressure? Any tips on getting it to release?

Re: Stubborn Clutch
Pictures?
If it were me, I would try to hammer a putty knife under the clutch. And be prepared to clean up or live with any scrape marks.
Use a putty knife where the tang comes to the end of the handle. And tap gently. At a very shallow angle. And gently. And maybe grind or file the corners of the knife rounded. So no gouges from them.
If it’s adhesive you’ll get them up.
If more fasteners you will feel them.

Re: Stubborn Clutch
What brand and model clutches? Some can be disassembled and repaired in situ... our older Spinlocks, for instance.

Re: Stubborn Clutch
If it's glued down with, say, 5200 or similar, you can soften it with heat from an electric heat gun. I wouldn't use a torch in case of ancillary damage. Just patiently heat the metal body of the clutch until you can gently pry it off.

Re: Stubborn Clutch
Another vote for heat.
Heat the clutch a bit then REALLY heat the putty knife up. Maybe even over the stove.
Slide a very hot putty knife blade under and see what happens. It will get rid of the adhesive or bump into more mounting hardware.

Re: Stubborn Clutch
I cut 5200 with a sharp blade on my Fein multimaster. Just apply a little tension to the hardware so the 5200 flexes a tiny bit, then slip the knife under it cutting the 5200. Very fast and easy.

Re: Stubborn Clutch
@JimCate: there are no labels/markings on them at all, perhaps worn off by time. Disassembly in situ isn't possible. The rods that run through them back out right into the teak grab rail at the companionway. Seems they can be re-installed from the other side...if I can get the thing off.
@defelsent, Benz, Chotu, fourlyons: Thanks for the tips, I was hesitant to use hammers, heat and knives, and will add gentle persuasion to them.
I'll let you know how it goes.

Re: Stubborn Clutch
Thanks for the tips. Some heat and (mechanical persuasion) did the trick. Nowe to figure out why they don't work well....

Re: Stubborn Clutch
Take pictures or video as you take them apart. There's a few little pieces that fall apart when you pull the pins.
They are easy to take apart and put together though. I just replaced the insert in our main halyard clutch. I should have taken a pic of the worn rope grab, the teeth were worn in a rounded manner, matching the halyard. It surprised me how worn it actually was.
