    Ugh. Trim tab piston replacement.-gctid399925

    So, I have the piston in hand and everything ready to go, but I cannot get the bottom nut off the cylinder. It will not budge. Not even with wrenches. I have soaked it in wd40 and still nothing. WTF. I think im twisting it the right way lol. I have tried both just to loosen but still no avail! Any suggestions? They are Insta trim Boat Levelers.

    Use a longer handled wrench for more leverage. Use a 6pt socket to prevent rounding out the head, nut.

      hmmm. I will try. Problem is I have to use a pipe wrench or so on the cylinder and the nut is approx 3 inches wide. Its supposed to just unscrew, but this isnt budging.

        It's been years since I've owned Boat Levelers, now Insta Trim, but I believe that the threads are conventional RH (left to loosen).

        Try hot water over the area and allow the outer part to expand a tad bit. Watch out where you squeeze with the wrench!

          Yup! Thats it. I will try the hot water tactic. Im sure these are the original cylinders from 1992 ish. Yea. I have been trying to be as gentle as I can, but this is really seized on there!

            I believe that one of the BOC members "Tabman" works for Bennett Trim Tabs. He may be able to provide some advice.

              This is news to me. When I've had to replace Insta-Trim cylinders, I've just ordered the whole thing and replaced it as a unit. Just what exactly is there to replace? Something new going on?

                That is a nut on the bottom. There is a piston with two or three o rings in there. Supposed to be just unscrew the nut and slide out the piston and replace.
