Figured it out. Making a wrench to fit the nut on the end of the large cylinder. Still not sure about the smaller ones.

Anyone know where I can order seals for inside the cylinder(s). I don't imagine they are as generic as a simple o ring I can find myself like the seals around the cartridge pump. Ill be ready to button it all back up and get out on the water with my new seats, new floor, and new amp/speakers /radio once I get the seals in the cylinder.

Is this it? Lists several serial numbers. Some are "x" and up? My ser no is 0b129822.

#5 is the repair kit for the large trim cylinder. #16 may be the complete O ring kit for the whole PTT unit. You might check with Crowley or a dealer for more info.

While trying to sort this out, I've discovered that, due to the pattern of the mounting bolts to transfer the cartridge pump to the new motor, the pump was actually spun around 180? inside the unit. Would this cause the trim to not operate properly? How should the pump be oriented? (Ill accompany this post with pics hopefully tomorrow)

I find it odd that I had no problems other than a leakdown before changing the motor. After changing the trim motor it doesn't wanna raise. The only thing tampered with was the cartridge pump and the motor, and new fluid. Replaced the o rings around the cartridge pump, but they looked fine. Took the cylinder apart, they all look fine too. Haven't tested it since replacing pump o rings, but it bothers me I haven't found anything apparently wrong. I'm ready to get back in the water

Does orientation matter?

Do these cartridge pumps ever go bad?
