I now have 3 hydraulic systems that will have air in them from being dismantled. The volvo drive trim , benett trim tabs and volvo power steering power steering.

any tips on firing up these systems?

Thanx

I just went through almost the same thing.

The Bennett system is self-bleeding. I simply ran the tabs up/down a few times and all was good.

I have a Volvo AQ290 w/trim, and I did the same thing; ran the drive up/down a few times, added some AFT to the reservoir to keep the level correct, and it has worked fine since then. I didn't have to bleed anything manually.

I can not speak to the steering system.

It's the same process for the steering, keep turning the wheel slowly from left to right back and forth until you no longer hear and feel any steering growl noise, just keep eye on the fluid level in the pump reservoir.

I think you would be smart to tie off the outdrive to the lifting eyes when you first fire the engine in case the steering wants to go to one side. After it stabilizes, you should be able to work out the air in the system like the other systems mentioned. I mention this because a friend of mine broke the steering yoke on his Bravo when it first fired and abbruptly ran to one side - costly oversight! Bill

I was actually going to run it without the drive on. just a shakedown run to check for leaks and stuff . then when all is good hang the drive and water test.

thanks for the info guys

Steering, if you have a 90* drill take belt off PS pump and turn pump with drill and add fluid as needed, I primed my entire hyd steering system this way without even firing the engine, it a slower process but you can start and stop a drill and add fluid easier than firing the engine, much more control IMO.

Steve this is a GREAT idea :yes:

Steve , Jim,

yes that is a great idea for a newer classic. :yes:

but It's not a merc or a chevy.


to get the power steering pump belt off the crank driven water pump and bracket needs to come off , that also means the alt. needs to come off.

Matty,

You could just crank the engine over with the positive wire disconnected from the + side of your ign coil to prime your p/s pump w/o starting it, and you'll be priming the engine with oil at the same time.

Walt,

I have a drill driven oil pump primer I have to run to get the oil thru the motor. then i'll drop in the distr. I don't want to turn the motor alot with out water don't want to fry the impellor in the crank driven HM pump, and don't want to force water thru the motor with out it running.

Yeah' I guess it's better not to, and to be on the safe side but I was figuring 40 seconds of cranking time split between 10 to 20 second burst wouldn't be harmful since the waterpump wouldn't be spinning fast.
Maybe just wet the impeller down with a dribble of wetness and squrt some dishwashing detergent into it?

I still have the fuel system to prime as well it's bone dry . I figured I have 3 schools of thought after I fill the tank and fuel seperator and pull the line off the carb and dumped into a container.

1. pull the starter wire off the solenoid and crank the key til fuel is dumped into the container.

2. with the key "on" run the oil pump primer this way I can check the oil pressure gauge and oil safety switch and pre lube the motor while I prime the fuel system.

3. grip it and rip it hook everything up and crank away


I am leaning towards number 2
