At some point the plugs should be replaced if they are hammered. This year we did seals, seal retainers, retainer bolts, washers and plugs. One of our actuators seal retainer bolts were stripped out so we had to size them up. If you have time to inspect them you can get what you need. All of that stuff wears out over time but you can possibly reuse all but the seals.

Re: Naiad lower seal replacement
Can anyone tell me the diameter and tpi for the jack bolt (manual fin removal tool) or the hydraulic fin removal adapter. I have a Naiad 252 system.
Thanks, Stan

Re: Naiad lower seal replacement
I just pulled my fins and seals. I last did this in 2008. I ordered seals from Naiad, $130 for four $5 lip seals; marine pricing.
I have no idea what size the jack bolt is as I had no way to measure it, sorry.Sky Cheney

Re: Naiad lower seal replacement
I am pulling mine out next month. The PO never maintained them so one of them is actually leaking water and grease into the bolt through the actuator. Obviously going to need seals and bearing but I wonder what else is damaged and if someone rebuilds the actuators if removed? I can't imagine I would be so lucky as to just replace bearings and seals. Anyone experienced this before?
