 Topic: WD45hydraulic reservoir
Posted: 04 Mar 2019 at 8:32pm |
|
I have a dump trailer that I pull with my WD45. The tractor does not have enough oil capacity to dump the trailer all the way. I don't want to revamp the trailer with a smaller ram. I added a extra reservoir on the side of the frame and ran a hose to the case drain. The oil does not want to flow into the factory case. It will, but it takes 15 to 20 min. to transfer a couple of qts. I tried mounting the tank higher and connecting to the filler port, then I had oil running out by the clutch. I guess you can't fill over full mark on the dip stick. Any ideas on how to increase hydraulic oil volume?

Does the extra tank have a big vent? MACK

Hard to make a lion out of a house cat. If you are set on using the WD45 on the dump trailer long term I suggest you make up a self contained hyd system on the trailer and use a drive shaft to the pto. Also there are self contained 12 volt units made for dump trailers that are pulled with a pickup.

That's only like a 3/8 pipe fitting in bottom. Time a fitting is screwed onto it there isn't much hole left. I think oil fill thread is bigger but difficult to plumb something in there.

Dad used to have a loader on the WD. The hyd. cylinders have two ports. The "power" side to lift the loader and the other side to use as an oil reservoir and plumbed to the drain hole for the hyd. reservoir on the tractor. Once the cylinders were filled with oil you had as much oil flowing back into the reservoir as you used to lift the loader. The reverse happened when lowering. No need for an additional reservoir. Did I make sense?

I had the same problem, made the suction tube longer on the pump and slightly over filled the reservoir and now it lifts all the way

There is prolly a one-way ram on the dump trailer, like the old trip bucket loaders

Check to see if you have a vent on the extra reservoir you added. If there is none, the reservouir is air-locked and oil cant drain out because no air can get in to fill the empty space when the oil drains out. Also dont way overfill it on the factory dipstick, but you already found that out. Ideally you would have a longer horizontal reservoir mounted at the same height as the torque tube, so you wont overfill and so the pump could suck the oil into it.

Exactly.....these rams have no "reserve". My Dad made a little square box reservoir for the WD.....I think that is 1/2" pipe that screws into the drain plug. Keeping the fluid at the proper level on the dipstick keeps the fluid in the tank at the same level. Been working great since about 1960 when he built the loader. I use it all the time to this day.

Make the reservoir so it uses the belt pulley hole. I've got an aftermarket one that does that. Dad used it as a pattern to make a bigger one. AaronSEIA

In my case Dad had also built a "buzz rig" to fit on the loader arms so he still needed the belt pulley.

use a diverter valve so that you are not filling the lift arm cylinders so allof it is going to the remote

You really need a seperate hydraulic system for the trailer. A pto pump from a truck hoist would work. also the charlynn self contained pumps work excellent as they have the res./valves/and pump in one unit.

I ran an older Woods backhoe with a oil tank, valves and one of these pto pumps. Worked great. The one I had was 10 gpm, but found this on ebay, which is larger, but almost identical in design.

Thanks for all the ideas. I do have a double acting ram, so I think adding another hose would be the easiest. I have the tractor in my shop, so I think I will check out adding the tank to the pulley side.

Wow, that puts out lots of GPM for only 540 RPM. 10 GPM is the norm for most front end loaders. This would work great on older tractors especially if they have live PTO.
