  • Leaking Steering Pin

    Is there any new knowledge regarding this problem?

    I removed my gimbal ring three times within two weeks now. The upper steering bearing was leaking about 1 drop every 3 seconds.

    On my first try I just replaced the O-ring with a new one. The old one was visibly flattened on the inside. This reduced leaking only a little.

    Then I replaced upper and lower steering bearings and stud (and O-ring again). I also shimmed the bearing with those plastic washers as described in the workshop manual. But it was again leaking a bit.

    I removed the gimbal ring a third time to check everything and replaced the O-ring once more. It looked dry for two days, but after two hours of driving it is leaking about 1 drop every 5 minutes again.

    Now I will haul out the boat a 4th time and try again.

    This time a am considering using a different (slightly thicker) O-ring instead of genuine Volvo Penta. The original seems to be 45x3.5mm and is very soft. It is much softer than usual NBR70 material.

    Did anyone already experiment with different O-ring sizes and materials?

        When you reinstalled did you lube the o-ring?
