4788 upper helm steering seal leak-gctid806664

[Guest]

Has anyone replaced the seal kit on the upper helm. The unit is a hynautic H-50

Not much information on YouTube.

Thanks Dave

Lots of info on here though. Do a search and will give a step by step rebuild with diagrams. I might be able to pull up a old post for you.

I rebuilt my upper helm on my 4588 same thing H50 got parts from Amazon about $35 for "O" rings. It came with instructions, still kind of a messy proposition but not complicated. If the helm pump has other issues Teleflex is the parent company of Hynautic.

Rebuilt upper and lower on my 4588. Initial noted red fluid stain all over my new pilot house carpeting! Fortunately it was a special "pet friendly" product and the stains came up with no problem. I figured if the lower is crapped out, might as well do both.

Used the kits from Amazon as referred to in previous post. Had a local general tech do the job. I have now rebuilt the piston/actuator and the helm seals. No issues as of yet.
