Re: Hynautic steering does not work
From your description, it sounds like you have a pretty substantial leak in the system somewhere. Having to constantly top off your reservoir is not normal.
Check to see if you have a by-pass valve plumbed into the hydraulic run, and verify that it hasn't been inadvertently turned to allow the hydraulic fluid to bypass your steering ram(s.)
To do this right, you need to crawl around and look for the telltale ATF stains. Trace them back as far as you can to try and find their origin. If you are lucky, then it'll be as blutoyz said a loose bleed nipple. It you are a little less lucky, it could be a loose union at one of your connections.
Moving a little further down the complexity/expense scale:
- Abraded or failed hydraulic line/hose.
- Steering ram seals leaking (will require removal and overhaul.)
- Steering pump seals leaking (also a remove/repair job, but wouldn't explain the overall loss of fluid.)
After doing the inspection, the next step is to refill and bleed the system. Just like the brakes in your car, any air in the system will keep it from operating right. If you've ever bled the brakes on your car, you can do this one as well. The only difference is that the steering ram has bleed screws on both ends, so you turn the helm to one side and bleed the compressed end of the ram, then go hard the other way and bleed that end of the ram. You'll need to do this back and forth drill multiple times, so having a helper at the helm is a real time saver.
