hydraulic tilt goes up but will not come back down

[webjack101]

I have just put in new brushes in the hydraulic pump motor which is the lift mech. for a 40 HP Mariner engine on a pontoon boat . But I can't figure out how to bleed the system . With pump & actuator on the bench , cylinder will only exstend and will not come back down . Has anyone out there deal with this sort of problem before or does anyone have any suggestions on what to do next, thanks.

Howdy, Jack.<br /><br />Whoever can help you is a lot more likely to be on the Outboard Engines Forum. I will move this there.<br /><br />Good luck.
