small 12V hydraulic power unit question

[davidh]

I have a Honda 4x4 with a v-plow mounted on it. I made a pair of single acting hydraulic cylinders using 1" hydraulic tubing and aluminum pistons, to control the V-shape without needing to get off the machine and change pin / rod locations manually when plowing snow.
I was stumped about what to use for a pump for operation of it and finally my mind settled on maybe using a pump / motor assembly from a car convertible top operator.
there are lots of them for sale on evilbay but I don't need to buy something that won't work.
does anyone have experience with these type of pump / motor units ? and / or an opinion on what im trying to do ?

I could be wrong, but I doubt that those pumps would put out enough pressure to raise the plow, but it might be strong enough to change the V configuration. The weight of a convertible top is negligible.

Another larger dia. ram or cyl could give the required lift, but not knowing much about these pumps I would still suspect the lift function would be slow.

If I remember correctly, a convertible top hydraulic unit will put out around 300 psi. If your Honda has a power takeoff you could use a power steering pump. A Toyota pump comes to mind, it has a separate tank.

You could try a tilt and trim power unit from I/O marine engine. I can remember if there double acting but should work. They have a small plastic reservoir with vertical pump/motor.

How about using a used or new porta-power type unit. It could be disconnected in Spring & used for many other things. I'm thinking in terms of a plow lift. I don't think it would work for the V adjustment since it is basically a hand pumped ram-powering unit.

I agree with jim that a power steering pump would be inexpensive and could be driven by a belt pulley or a 12volt motor---Dave

The pump on my V-plow is a Parker 108AEC19-BLL-1V-13-13-YZ.

They were used on Volvo Penta for tilt and trim.

It's rated for cold weather use and the internal relief is set at 1300 psi.

There hydraulic winch pump too. You will find this on off road cars.

If it must be hydraulic, you can check here: http://www.surpluscenter.com/hydraulics/

But, you may want to look into linear electric actuators. I believe there are some available for 12V systems, but it might be a good idea to run them off a separate onboard battery, as they can draw quite a bit of current under load.

My ATV only has a straight plow, so I just move it up and down with the winch.
