I was wondering if anyone could give some much needed advice-
I have installed my new autopilot
system, and am finishing with
the hydraulic arm/pump. The arm is the one the boat
came with (seemed to work
fine with the old unit) and I'm installng the new rpu160 pump
So, I mounted the unit as per the instructions, and connected the two
couplings to the arm, and the center one to an expansion tank above the pump
So, according to the instructions, it appears I'm suppsed to bleed the system by letting it draw oil
from the tank, and loosen the couplings
at the hydraulic arm to allow the air to escape.
Unfortunately I tried to do this, and no fluid was drawn into the
arm/tubes. So I figured that maybe I needed to get some fluid in first
and it might draw it through better. So I closed the arm,
disconnected a coupling on the pump side, and let it draw the fluid right out of the bottle. At this point it happily pulled the fluid into the hose and
hydraulic arm. Si I connected it back up and tried to move the wheel
cause more suction on the other side and fill the whole system.
Unfortunately, I couldn't move the wheel
much, as I then realized the pump
isn't letting any oil
pass throgh it when you turn the wheel. I must
be missing something, but the old pump I had would pass the oil from one side to the other, and draw or deposit into the tank as needed.
Has anyone installed one of there before? I'm wondering if there is some bolt
or screw I need to remove to let it work
properly? Does the unit need to be powered on for some reason? (obviously that won't work as I need to be able to steer the boat
with the autopilot
off!). Or have I bought the wrong unit? (I hope not!). Or is something else afoot here?
I'm open to all suggestions! Thanks for reading this!
Any advice would be much appreciated here.
