Hynautic Hydrauliс Controls

Check back to the other thread.
☺

Sorry it's 954-895-487nine. The filter is usually a S/S mesh screen if I remember correctly.

He'd work on them for me, but I send him a ton of business every year for the past 20 years. None of us have worked on Hynautics in 20 years, they're practically extinct down here just like detroits. That being said he mentioned that you mentioned all of your stations are stiff, I've usually found a stainless screen in the bottom of the resevoir but in the fitting that screws onto the bottom of the resevoir. But, it all of the stations are stiff, the commonality is at the motors and gears. They may have a filter in each actuator as well or in a block where all the lines go into may also have a filter. Are all of the stations working? Are they all equally stiff? Both gears and throttles? How long have they been stiff? It's been 20 years since I messed with Hynautic also so trying to go by memory. You know it's probably more cost effective to rip out all of the hynautic and go with electronic controls for the helm and tower and do away with the other stations, when you consider everyone's hourly rate and hunting down and ordering hynautic parts. Because by the time you're done screwing around with the Hynautic to get everything right, you'll have spent as much. It's obsolete and any parts needed in the future will be impossible to obtain........

The filters are inside the system, nothing more than metal screens, you will not see them unless you start dissassembling things. They're not external filters that screw on. Trust me when I tell you this, electronic controls are very reliable these days and I'd rip out those antiquated controls quicker than quick and replace them, you're going to spend a lot of money trying to fix them.

Everything on your Hynautic system is 30+ years old and very very prone to failure at this point. You have 100's of feet of hydraulic hose that is past it's lifespan......if that breaks anywhere, and I mean anywhere, you just lost everything. Maybe even lost it stuck in gear!!!!! You can figure out a way to get things moving if you lose electronic controls, shift gears manually in ER, etc...... Hynautic is so passed it's lifespan you can't really even find replacement parts to keep it up and running. I've been down this road a bunch of times on yachts and it's time to just retrofit, otherwise you end up spending a ton of money and still have old junk that's ready to fail........and end up retrofitting electronic controls 1-2 years down the road after you've already dumped that same money on fixing the hynautic, then a year later fixing something else on it, and etc.

I'm pretty sure that this is possible also with Kobelt levers, because I've seen a sistership of my boat (which was normally powered by MAN mechanical engines, controlled by cable levers) where the first owner wanted electronic throttles instead, and the builder fitted the Kobelt, taking also the opportunity to install the backup cables+levers inside a cockpit locker, in order to make the boat maneuverable in emergency without having to stay inside the e/r.

Anyhow, I'm not surprised to hear that you managed to fix your Hynautic controls, because a boating mate of mine has them on his boat of the early 90s, and so far he only had a minor problem a few years ago, that a mechanic with specific experience managed to fix perfectly.
In fact, as he told me, most if not all the parts subject to wear are just generic hydraulic bits, relatively easy to source.

I don't think it would have been even possible to control your new powerplant with anything else than an electronic system.
I mean, the C18 are controlled by an electronic governor, and there's nowhere to attach a mechanical cable to drive it.
Can't remember what g/box you had mated with them, but the same logic goes for many modern gearboxes: they are controlled by electronic solenoids, so you couldn't operate them with a mechanical cable even if you wanted to.

I remember a customer that had ZF electronic (later Mathers) controls with a helm door that opened with Morse cable control heads. All required was to place the mechanical cable ends on the servo levers in the engine room. Always thought that was a cool backup.
I do have some experience with lightning damaged controls.
It takes a real direct blast to wipe them out. But when it does, usually nothing else is working anyway.
Been on boats (Volvo, Cat, MAN) where the ECM has fried and the electronic controls have been fine.

One GB customer had Cat electronic engines and the clutches where mechanical slaved from a Mathers like box. Nice lightning strike 3 boats down. Now, no way to rig or operate the throttles past idle. Clutches still worked fine.
Teleflex made this system and there was a lil micro board in-bedded in the I/O cable that fried. I lost lots of scalp hairs over this repair.
Oh, new I/O electronic cables from e-bay..
Same boat, that smart Naiad controller,, was the most expensive thing to fix from this near strike.

Now as a reminder; Mechanical Detroits don't need no stinking electricity to run and go..
