Dump trailer fluid check

[Ronsway]

I have a small single axle 4X8 dump trailer. The pump, hydraulics, and battery are under the bed. How do you check the hydraulic fluid? To get to the pump and tank I have to raise the bed. Normally you want all hydraulics relaxed to check fluid level. There is a dip stick on the cap for the reservior with a low and full mark. I am not sure where the bed should be to check. All the way up or up just enough to reach. Also do you check it with cap threaded all the down or just resting.

Many of those have a translucent plastic tank. Does yours?

Does the bed go all the way up without starving for fluid? If so I’d leave it alone.

The pump, tank, & valve are one unit. Tank is metal. It does go up (without load). My concern is that it has been sitting for several years. I just don't want to get it loaded and then not be able to dump.

put it fully up, then check the level, when its up, it will be at its lowest point., how exactly do you plan to fill it in the down position anyway?

The problem is those electric pumps don’t have much reserve. If you overfill the tank when the bed is up it will at minimum blow fluid everywhere when it comes back down. It could explode the tank if it doesn’t vent fast enough.

I own one, as long as your above the low line your fine.

Now you see my problem....

It takes the same amount of fluid to dump loaded or empty. If it doesn’t run out empty and it doesn’t leak it will be fine.

What about when you check it - do you leave the cap set on top of the treads or thread down?
