The only mechanic I've so far found who claims he's very familiar with Hynautic Hydraulic Controls seems to have gone MIA so like a ship at sea with no plumber, the issue of stiff controls has fallen on me. I believe the fluid is good but until yesterday was of the mindset a little filter in the system may be partially clogged thus creating a partial restriction to the fluid flow. The manual shows where a filter supposed to be located but after letting out all the air pressure and removing the nut/cap discovered there is no filter. Anyone ever mess with this system ?
The lil filter usually works on the return line. I do not recall a filter on the control system. I have a few old pubs on this. Please give me a few to find something for you. Also, It's cold and even if it is glycol based, it will flow slower.
I wish it was only when cold out there as the boat's not seen me on those days. Here's from the manual showing a filter location where I've none.
I see your picture is directly from a Dumb-metic manual. Not a good start. Dumb-metic support and publications can't find their asp with either hand or know where a filter is. I'm looking for an older manual when TeleFlex was bending over the Hynautic equipment. This is where this later reservoir/manifold design came from (IMO). I understand the real Hynautic controls used the same R06, 07, 08 as the steering system did with remote terminal block (as the rudder block). I'm just in, please give me the night and morning to find something for you. My Hynautic files got dumped again and I'm still trying to recover all my old files. BTW, Windows 11 and Windows Backup sux.
Kewl. No plans to replace Win 10 at this time. Picked up a Survivor USB and every now an then copy most of the HD to it, which reminds me, not done it in too long.
Just followed up on the other thread you started with. Skippy J may have an idea on the filter (if equipped) is behind that plug and may need some help in removal. I have to also state, on any good day, Hynautic controls are always slow. I hate the Hynautic controls on my best friends Hatt. I'm used to pushing big 1/2" grey Morse cables on my Bert. Are there any Hynautic control boats around that you can compare to? It may just be the way it works that you (and I) don't like.
I'm still ticked they turned XP off. Purchased a new win 11 box with 1 TB solid state drive. Fast as heck. What else do you do with a fast 1 TB drive,,, Load it up.. 5 months later SSD died. F M Relied on the windows system to keep all backed up in a cloud. Double F M I still have junk scattered around a couple of old boxes on da boat and in the shop. I just have to power them up, plug in a Cat5 cable, remote in and search for old folders.
Ages ago I used to take turns running a buddies Striker with same controls. Although there was an annoying delay when switching in-out of gears I believe that was the transmissions; the controls were not at all stiff. I also spoke with someone awhile back who told me his took very little effort.
Yes, very little effort if your not in a hurry. I do have a feeling you are going to find some over tightened tubing fittings restricting the fluid flow.
I'm thinking, since the issue is with all three sets of controls, the problem must be at a common to all location. Thanks for the support.
I had my Hynautic shift controls rebuilt a year or so ago and the difference was dramatic. Not at all saying that you need to rebuild but stating that I have had stiff Hynautic controls and now I have very smooth easy to operate controls. My point is Hynautic can be smooth and easy.
Same for me they are easy and smooth for me. I don't have much if any delay in shifting either. I did have a high idle issue which was resolved with bleeding air out.
Don't get angry at the question...did you confirm your air pressure? My first step would be to loosen the return line and confirm free flow of fluid through the entire network. Then begin chasing back upstream to find the hangup. These stations all work together, so a blockage could exist at any station or even the slaves. The return line is the tell tail to find the culprit. https://manualzz.com/doc/o/erjmx/hy...d-service-troubleshooting?p=6#google_vignette
It's possible that tightness is within a single control, but then the issue wouldn't likely exist within each station unless that "bad station" has a check valve hung up...?
Approximately 25 years old when rebuilt. Wayne Peyton did them. He is in Stuart. I think I sent you a PM with Wayne’s contact info and another guy out of Ft Myers. If not let me know and will be happy to send you both of their contact info.
Your knowledge on this and other mechanical matters far exceeds mine. I think you are saying he could find the problem in one station affecting all the others and if something simple then no need to tear apart and rebuild. I have decided to keep my current boat. So this will be my last (big to me) boat. My boat was built in 1995. I have over the course of my ownership when an issue starts happening with frequency i will just go ahead and replace with new or rebuild. My Hynautics were stiff so I thought they have some marine age on them and had them rebuilt. I am more reliant on others (mechanics) than you so when I get with someone I like and trust I will be proactive and replace or rebuild instead of troubleshoot. Now that I am mostly retired I am doing some of my own mechanical work on cars and toys trying to gain some mechanical independence that hopefully transfers to the boat especially when in the Bahamas and there are few options.
Pressure at 80 psi where I set it several days ago. Wouldn't loosening any lines cause a flood of fluid ?
