    My boat's starboard side trim cylinder is leaking and Volvo does not have seal kit for rebuilding it. They sell the whole kit and it is expensive, $1850.

    Before putting up a white flag, I want to hack it, by using sealing kit from OMC or something.

    Can someone show me how to disassemble this cylinder?

    Thanks

    Ryan

    A human assembled it, look for a snap ring, lock ring, etc. Does anything unscrew from the other end

    Do you happen to know where I can buy the trim cylinder rebuild kit? I went to Volvo Penta shop in Houston and they don't sell rebuild kit for trim cylinders.

    Thanks @Bt Doctur

    Most cylinders unscrew the cap from the rod end, Do you have a model type of the drive?

    Ryan, it would be helpful if you were to post the year and model of your engine and stern drive.

    There is a man in Canada who may have the rebuild kits for these.

    Keep an eye on E-Bay sales if you would like to simply replace them.
    FYI..... due to most sellers not using the correct terminology, I would vary your search key words.

    Volvo Penta ram cylinders.
    Volvo Penta hydraulic cylinders.
    Volvo Penta trim and tilt cylinders. ... etc.

    Yes, Bill and I go back many years regarding Volvo Penta.
    I tried calling him earlier this morning... no answer.

    I would contact him and see if he can help you when the parts come in.
