Helm Replacement

[MTrader34]

Looking to replace the hydraulics helm in my 1981 MT 34. Current one is a leaky Syten H-10 system. I believe I have found a SeaStar replacement combo but don't know if this is a good fit. Any advice welcome

Sounds like a big job. Are you sure you can install some new seals in the present system. I think they are mostly "O" rings.

I rebuilt mine this winter, it is pretty easy with the factory kits. Not sure what the Syten H-10 system is though, I have a Wagner helm pumps. For my helms the factory rebuilt kits include a gasket and all the o-rings for $50, so $100 for both helms, beats thousands to replace with new units. If you don't want to pull and rebuild them there are places that will do it for you.
I would research rebuilding before you replace.

I have leaky O-rings also. Are there any diagrams or videos on replacing the O-rings?

SyTen was the Teleflex introductory model Sea Star system. This from the SeaStar site:

SeaStar Solutions

SYTEN HELMS MANUFACTURED BETWEEN 1978 – 1984, THESE HELM PUMPS ARE NOT FIELD REPAIRABLE. NO SEALS AVAILABLE

A Sea Star helm would be a direct replacement when selecting against the cylinder size and number of turns.

Isn't that a convenient statement. I seriously doubt that they cannot be rebuilt.

They take the same stance on Uniflow valves in older Capilano systems too, but if you have the tenacity to work through it, a uniflow valve is certainly rebuildable and even repairable. I would wager the same can be said for a Syten H-10, even though I've never seen one.
