Opacmare passerelle - can you manually collapse it

[jfm]

That simplifies it nicely. One pump unit, 4 hoses, 4 vlaves (or 2 reversing valves, but 4 solenoids in any case). Test the sols for continuity with multimeter, test you have 24v at each solenoid, and see if the valves move/have a button to operate manually. Should be easy diagnose.

I like the separate pump architecture that you have. On my boat Fairline buy all the hydraulic parts without pumps, then fit a pump from Phoenix in UK that operates everything. I de-specced this and got separate hydraulic pump/tank/valve units manufacturer by manufacturer for passerelle, hilo, crane and thrusters/stabs/winch. I much prefer this, as when you have a fault you only lose one item

Edit - oops was replying to #18 without having read #19 and #20 sorry. Ignore me.

Happy to hear that the troubleshooting was effective, but I don't think it's worth bothering with a more limited usage.
In my experience, stuck solenoids are one of the mysteries of mechanics: probably more than 10 yrs ago, my port engine refused to start for the same reason.
The problem was temporarily solved by gently (well, almost) hammering the engine starter, while swmbo turned the start key.
Back then, I thought that at the end of the season I should have asked my Cat mechanic to look at it, but eventually I forgot to tell him.
Long story short, it never happened again in all the following years and a thousands or so of hours, with countless engine starts and without ever looking at it again...

two months later,

just to stress what MM mentions above, just fixed mates bezenzoni on his P45 which would extend but not retract (was working fine till last week...)
Removed the two solenoids, wiggled the cables, swapped them over, no luck wouldn't retract, swapped oilpressure pipes, worked fine but wouldn't extend
So hit with a small hammer half a dozen times the shaft where the solenoid fits and wraps around, all working fine now

So if all but one works and swapping cables wont fix it, remove solenoid and hit the axle a bit, wont cost much and wont take more than a few mins (if you've figured out which solenoid does what that is which is something I'd recommend anyhow as well as knowing WHERE the pump and solenoids live in your engineroom or lazarette).

PS. maybe next winter we should setup a tech FAQ for the YBW site by picking bits and pieces from various threads??

I fixed Jez's by working the solenoid valve free.
Here is a pic of a similar valve

If you get a small screwdriver and push the valve where I've pointed with the red arrow, you should be able to ease a sticky valve.
Once it is eased, you can do the same thing from the other side until it moves freely.
Also have a look here:-
Page 4 shows a diagram (section) of the valve and how it works.

Sometimes (over time) these valves get stuck so just easing the plunger that runs between two solenoids can often resolve the problem.
I suggest that hitting it is a last resource!!

thanks Mike,

there was 20odd years of muck on them plus a lot of oil and the lighting was poor. Couldn't see anything on there, just a 13mm spanner head cut on the what must have been a cover under which the sticky plunger lives.
Thanks for the diagram, will help understand a bit more how magnetism and springs work together to lift or lower your passerelle

cheers
