Close the release or dump valve while bleeding the system. You are correct that the middle fitting is the suction line make sure that it(or any of the fittings) is not loose. Especially where it mounts to the pump. I would usually remove one of the larger fittings to get a wrench on it since really no space.
Hydro Gear Pump problems after servicing
I have a Hydro Gear BDP-10L-117P on a Lesco walk behind mower. It was leaking fluid at the trunnion seal so I decided I would replace the seal. I got a seal kit and took it apart and replaced all the seals in the pump. Put it all back together and now the wheel will not turn. I tried to bleed the system many times by opening the release valve and moving the controls back and forth. When I look in the fluid tank the fluid going back in looks foamy and has bubbles. So I assume air is getting into the system somewhere. Where exactly can air get in? There is one suction hose going to the pump in between the two hoses going to the motor. How do I check to find where air is getting in? Any advise would be great cause i dont want to spent $500 on a new pump.

Any chance you put the top charge pump on incorrectly? Its the small oval housing ontop of the head and if installed wrong your pump will not work.I tightened the suction line really tight and I cleaned the fitting out. Is it possible for air to enter between the top mounting plate and the lower housing of the pump? There is a gasket there that I replaced. This is driving my crazy, i checked all the fittings and cleaned everything and it still doesnt work.
Sorry I didn't get back to you sooner but it will be fine, glad that worked for youDo you think that did any damadge to the pump by having the cover on backwards??????????? I hope not. Thanks for the help.!!
