Help! I took my first stab at purging a Hynautic steering system with poor results. The system I have bleeds only at the cylinder. I followed the Hynautic directions step by step but ended up going through three quarts of fluid and still no steering. My inclination is to say I opened the bleeders too much which actually allowed too much fluid to exit the system and allow air in from the reservoir. Should I have just barely opened the bleeder to allow a trickle and been more patient? Is a stronger flow needed to purge air? Am I going down the wrong road completely? Also is SeaStar fluid the right choice is there a generic fluid that works as well Thanks in advance

One thing is, you should not be doing this alone. Someone should be turning the wheel at your request and adding fluid while you wait for the bubbles to end. You may be allowing air to re-enter if I understand what you are doing. Ron Rogers

Dave, How interesting. I recently renewed my Hynautic steering system. Sent the helm pumps and tiller ram to an outfit in the Carolinas to be professionally rebuilt. Replaced all copper tubing with new hydraulic hose. Fresh from top to bottom. Now, and this is important, do you have a 3 hose system? Gary at Marine Control Services, the man who rebuilt my equipment says any ATF fluid can be used and any type can be mixed in. Before attempting to bleed, drain the reservoir, pull the filter and carefully clean it. Make certain it's clean or replace it. If this filter doesn't allow fluid to pass , you will never be able to bleed the system. Don't ask me how I know. Bleeding takes a long time. First, add the fluid and pressurize. Bleed at the tiller ram on both sides. Make sure the reservoir doesn't get too low or you'll just get more air trapped in the system. When you're not getting any sputtering at the ram, you're ready for the second step. Make sure the reservoir is nearly full and has around 30 psi. Back off the two nuts on the pressure relief valve and go to the highest station. Turn the wheel, say starboard, 50 turns or so-slowly, 2-3seconds per rotation. Go to next lower helm and do the same. In my case I would then go to the auto pilot and repeat. Now, go topside again and turn 50 rotations to port. Next lower helm, the same. Auto pilot. The same. Let her rest for 8 hours and repeat. That should take care of it. Regards.

Hi Dave. Go to the Seastar website, then to the Capilano section, then to the PDF format piece on filling and purging the system. I believe t will tell you all you need to know. Cheers Glenn Williams "Stirling" Universal 41 Port Phillip. Australia.
