    Re: Leaking trim seals

    Rich

    Changed out my seals & O rings. Ended up changing caps and rods.
    Rods were mushroom out on the end. My caps are made of Aluminum.
    Punch didn't work for me. (screw them up).ended up buy a spanner wrench to put the new ones on.Good to go. this was done on a 250 HPDI. Thanks for the post. Tony

    Also, don't forget to check hydraulic supply places for some of your seal needs. Bought a seal for my SeaStar steering a couple of years ago for $4 at a place in Pflugerville. Pretty standard stuff and much cheaper.

    Bumping this great thread for some additional info.

    (my outboard is a Yamaha TLR90)

    My tilt cylinder is the one that is leaking. Putting the motor on it's manual tilt bracket and removing the pin on the upper side of the tilt cylinder is easy enough. What I haven't found out is - does the mount cylinder at the top of the piston simply unscrew to allow removal of the end cap and of course replacement of the dust seal? In other words - is the end of the tilt piston rod threaded for that top mount?

    My 2nd question is a matter of opinion. My trim seals are not leaking. If it ain't broke, would you fix it? Or should I just leave them alone and wait until they leak?

    Finally - please confirm what fluid I should use to re-fill this assy.

    Thanks in advance.
