Plow Hydraulic Unit, can I turn it up?

[Matt Bachand]

--------------------------------------------------------------------------------

When Cleaning out frozen water outta my resevoir I noticed what appears to be a set-screw on my hydraulic pump inside the resevoir. It must control the flow rate of the fluid, making plow movement faster?

Has anyone tampered with this? I have a backup unit, so perhaps I'll try it on the backup and see if it makes the plow movement faster. I'll post a pic in a few.

The screw is the shorter one, closest to elmo's hand next to the long shaft that goes into the starter like motor.

I know this is Off topic, but I want to share with this group, and value opinions of this group, moreso than the strangers elsewhere (where I also posted) Also may be interesting to those who live where their trucks never rust.

Where else did you post?

In the Plowing Category. Barely any traffic there.

Im not sure on your plow but on the western plows there is a set screw that just adjusts the relief valve. It shouldnt move faster just make it lift more or blow seals out.

I think i'll leave it alone then. Case closed.

Is it electric or belt driven? My dad used to be big into snow plowing and the meyer plower had a belt driven pump that was super slow. He said any power steering pump would run it and lift it in about 1 second.

Nope electric. That gizmo sits inside the resevoice directly underneath a huge coffee can sized electric motor. Resembles a starter motor. Completlely separate of the truck.

My dads western had a winding go bad in the motor. He took it to a place that rebuilds electric motors and they removed the bad winding and said the it will work faster now. Maybe they make faster motors for yours. Im not sure on yours but the wester plow turn nice, there not real slow. Raising it up is a little slow.

The only way so speed it up would be get a faster motor or smaller cylindrers.

You don't need a faster motor, you need a pump that will put out more volume. I could probably get you a higher volume pump, measured in cc/rev.

See if you can find a manual online.

Western has their's on line.

On western's there are three settings.

The Quil that is the flow control for how fast the blade drops.
Overal pressure relief, IIRC is fixed and in the pump
The trip relief, for the blade tilt. This adjust the pressure when it will give way if you hit something off center. (tilts the blade, prevents blowing the tilt hoses)

The quil is the only one to mess with.
Changing the pressure ones will cause early trips or blown hoses on the tilt cylinders etc.

Thinner oil is the only thing that will make it lift faster.

Yeah, that and a pump that puts out more volume, been there done it, makes a world of difference.

 

[Michaeljp86]

You could try synthetic oil, probably wont help a whole lot

Matt, didn't I see you on Plowsite? If not, check it out. Some of the same people from here and the other place. Someone will know in the Fisher forum.

Couple other plow forums are LetstalkSnow, my fav, and a new one Letsplow.

 

[Matt Bachand]

Great, more addictive forums... Just what I needed. Thanks for the info guys, I just chewed up a few hours over at plowsite...

I have a hydraulic pump mounted under the hood of my farm truck to operate my bale deck I feed the cows with. It's activated by an electric clutch like an air cond. comp. They come in 3;5;7;&9 gal/min. It would fit where the vac pump was.

Pics please! I could go central hydraulics for the plow!

This isn't the one I have, mine is a gresen. I don't have any pictures of it but will try to get some later.

It can also have a serpentine pulley put on it, it costs more though.

They can be set up with cables to a three way spool valve or an electric over hydraulic control valve which is what I have.
