I have a hydraulic leak in my main helm station steering system. How does one get into the back side of the helm station to access wiring and hydraulic systems?

It's a pita. The gauge panel comes off. I relocated the gauges and converted to an access panel. Should be another panel in aft closet ceiling.

Lift the dash up.

I assume you both are suggesting that black gauge panel lifts up. I figured the same and tried it - It came up about two inches and offered decent resistance after that, so I assumed that I would be unwiring everything on the gauge cluster if I pulled further.
The panel in the aft closet ceiling is where all of the hydraulic fluid had been leaking all over my clothes washer all winter... That particular hole will need to get substantially larger to be of any use at all, maybe that will be tomorrow's project. Even if I made that hole large enough to stand up into I don't think I could move while I was in there. It is also quite a way up to the hydraulic lines.

It's a mess up in there.🤣
I was a bit surprised the wall behind the main console in the main salon didn't easily open up with access to that area. It looks like there is some 3/4" ply in the way there though - plus all the copper hydraulic lines run up behind that salon wall.
Thanks for any further suggestions.
 
Mine was a rats nest too. Once organized, you can stand on a ladder in the closet and do what's needed. Barely.
You could last option cut a hole from the salon, then trim it out and hang a picture.
 
Managed to pry the gauge cluster panel up just enough to get my arm down the back. Not a great situation, but better than not getting an arm in there at all.

The oil and transmission pressure gauges are stopping it from lifting any further, if they were 18" longer there would probably be access.
I did manage to get a look at the back of the helm pump, and it looked like one of the fittings coming out of it was quite wet. So I managed to wrestle a wrench in there and tighten up that fitting. Hopefully that solved it for now.

The larger issue will be getting the panel to lift in a useful manner, then I can tidy up all the abandoned wiring.
Anyone know what hoses are used for those pressure gauges? My other alternative is to go electronic on those gauges and not have oil run throughout the vessel. One of those gauges may also have a slight leak as well. Tightened it up a bit too, but it may be leaking out of the gauge, can't really see.

Thanks all.
 
My oil pressure gauges were electric but my gear pressure gauges had a length of flexible hose like yours from the hard copper. It might be easier to remove them and have a hydraulic shop make up new ones at the length you want.

So, I have wrenched this fitting as much as I can. The leak has slowed, but it is still there.

I think it may actually be coming from the fitting that is in the helm pump. That fitting had no more room to tighten it, it wouldn't budge. Is that fitting removable (I didn't try to loosen it yet?)
I did try and loosen the hose fitting and quite a bit of oil started pouring out, I know some of that will be from the helm pump itself, but if I let the pressurized air out of the reservoir will it push less oil out?
I'd like to remove both fittings and take a look at them without soaking the washing machine below any more than it already has been ;) Then on reassembly I'd use some thread sealant on the small fitting which would help reseal it if I can get it undone.
Thanks for all the help so far.
 
Once the air pressure is released the oil will not spurt out, just some oil from gravity. There may be an o ring inside the steering block behind that fitting that can be replaced.

Patience....
Tighten it up and watch your pressure gauge a few days.
Just because you made a tension adjustment and you think it is still leaking does not mean squab.
It could still be fluid dripping from the previous leak.
Patience.
Clean up what you can and wait, watch that pressure gauge.

Yea, raspberry the guy that put that rats nest together.
 
It was definitely still leaking today, I put a clean oil absorber sheet around the fittings in question last night and they were wet with oil this morning.

So I pulled it all apart again today and put some thread sealing compound on the threads of the fitting that goes into the steering pump. I only dropped that part into the laundry room 6 times before I got it threaded on. Pretty slippery with dripping oil and sealing compound.

I only broke both engine start switches and a few wires in order to get my arm in far enough to use a wrench, sigh. One step (maybe) forward and one of two back. This happens everywhere I go on the boat.

This access MUST be improved, it is unworkable - no wonder nobody bothered trying to fix all this stuff.

The flybridge has a set of mechanical gauges sitting right beside a set of electronic gauges for each engine. Why replace the broken ones with ones that work? Just put new ones in beside them and leave all the other crap behind. Sigh.

I am hopeful that means that there are electronic senders for all these gauges already and that I can simply replace these mechanical ones with electronic ones and get rid of all the oil pressure hoses that are stopping me from opening the gauge panel.
 
I hope you used a hydraulic sealant like locktite 567 not standard white teflon paste or tape.

It's a hydraulic system so you need to use the good stuff. And by the way that stuff is a bit pricy.
 
Yep, I have hydraulic thread sealant. :)

Most all of my boat projects are centered around making things more easily accessible for when they need to be fixed next time.
