Bleed ITS steering system
Installed rebuilt engine a few months ago. I am having trouble getting the air out of the system. It is the mercury ITS system. The only thing we have not tried is to bleed the system with the engine running, I cannot find anything about how to do this. Should I try to bleed it with the engine running, if so how should I go about doing that? |
Fill power steering pump start motor turn one direction shut off engine fill pump again do the other direction repeat till leavel is Steady let it sit for a bit small bubbles will get bigger. If you have someone to add fluid might help try not to run it out when you start proses. |
or you can pull the belt from the ps pump and spin it with a drill
|
service manual bleeds it and say is bold DO NOT START ENGINES fyi.... whats your email? I can send you the manual I have it pdf.

Just some clarification I should have put in the initial post. We did the initial bleeding without running the engine when it was connected. Once we ran the motor it seems to still have air trapped that will not work its way out. The system also has Automatic transmission fluid in it should I change it out for power steering fluid? That is what was in it before the motor swap. What is happening now is the fluid is foaming due to the excess air and overflowing the reservoir when running the engine. |

does it have remote reservoir ? |
What pump do you have, where does the return from the helm connect, does the remote reservoir have 1 or 2 ports ( fittings )
|
The pump looks like stock PS pump. The reservoir has 2 lines one to the pump and the other looks like it goes to the cooler. |
Is the cap to fill it on the pump? |
No on the remote reservoir. |
Post a picture of reservoir and pump |

Thanks to 30Outlaw for giving me a copy of the manual. We will try to bleed it tomorrow according to the manual. I know this was not done like the manual shows when we installed the engine. I will let you know how it goes. |
Can I get a copy of this procedure , I need to do this also when the engines go in.....

Update: we got the system bled down, but after a few turns it started foaming again. We managed to find a small leak on one of the cylinders that is leaking when you turn one direction and seems to be sucking air when turning back. Have to order kits and rebuild the cylinders. Thanks for all the help!!! |
I did mine today, talked to Doug at Master Tech drive service and he told me the easiest way, so here goes.......connect 2 clear plastic hoses from the bleeder block to to the reservoir tank and top off tank with fluid, then pinch off the return line from the helm this will force the fluid from the tank out the bleeder and back to the tank, then open the bleeders 1/2 turn and start to rotate the wheel in one direction while keeping the tank full.........dont let the hose ends in the tank to become uncovered with fluid, keep turning the wheel one way till all the air is out, then rotate the wheel in the other direction ( keep the tank full ) until all the air it out. then rotate the wheel back and forth till you see no air coming from the bleeder, then tighten the bleeders and remove the hoses, then take the clamp off the return line slowly because it will pull some fluid from the tan, then climb out and check the drives for movement, you shouldn't be able to move the drives at all, if they move you still have air in the system, then get your azz back in the boat and do it again..........:D.........The end
