hydraulic engine trim question

so I got my hrdraulics sorted thanks to this forum, now I got another problem. The hydraulic trim for the engine right works fine but I need to put the pump inside the boat tidily. Ok so to do that I need to put the hydraulic hoses through some holes, this intern means I need to disconect the hoses. So because the weight of the engine is on the ram underneathe the engine the pressure in the hoses will be the same, how do I disconnect the hoses without hydraulic fluid pissing all over the place????? I did try to take the weight off too with a wedge and that did not seem to work.
The other question I got is that if I was to not really care too much about the fluid and let it piss out and relief the pressure if air gets in does it flush air through the ram and into the pump so I can bleed from the pump?

P.S I am really taking advantage of this forum its sweet all the knowledge of the world resides in this forum booya

trim ya engine right in.
disconnect hoses from pump( you will loose some fluid but don't worry about it)
mount pump where u want it
re connect hoses
refill pump with fluid (dont put filler bung / dip stick back in yet)
trim right up as far as she will go it may take a while as the air is bleeding out of the system.
trim right back down
trim right back up
right back down
check fluid level top up again if necessary
put bung back in
clean up mess you have made
job done

The Merc Oildyne pump

is "self-bleeding" as mentioned above by Burty, I have two in my boat, one for the engine and on for the Stainless Marine jack, I have dissasembled them several times and never had any problems with air in the system, just run the engine all the way down like burty said.
And keep an eye on the oil-level while running the system again when assembled, make sure the pump don`t use up all the oil in the oiltank so it sucks air and you`ll be fine, it will foam alot in the tank when running it up and down, but that is just the trapped air coming out of the system....Good luck!

prolly a black plastic headed screw on top of the resevoir maybe between where the hoses go, when it comes out it will have a pointy thing on the end this is the dip stick

Here you go..

thought a picture would help...As Burty said, a black-plastic screw between the oil-lines..I used a cleaned ut Ketchup-bottle with ATF-oil and an 6mm pneumatic-hose/line attached to it,to squise the oil trou since Mine is located all the way in the back towards the transom-hard to get to..Hope it helps..

...........

In the specs from Oildyne it says use ATF oil or any clean hydraulic oil with viscosity range of 150-300SSU att 100deg. F....

I went with the ATF...work just fine.
