Monarch is owned by another outfit now but someone there is checking for me.

Monarch is owned by another outfit now but someone there is checking for me.

Monarch is now Dynamic Jack, this is a 1 year old pump, that is on a twin ram dump trailer. The return dumps into a hole,they made in the reservoir, it leaked,because there was a cover installed on top, with no clearance. It cracked the reservoir. I will try to locate a replacement, this should work for your trailer. Here is the model number.

I think the axle notch is still a weak link and just buy a separate tank or make one

I think the axle notch is still a weak link...

Why is that and what do you think would make it more solid?

I have seen some torflex axles welded just to the sides of the frames so the bed can be lowered to the ground inside of the "U" of the frame, of some trailers.

Kind of like these.

I figured that the bracing and connecting it to the 3x5x1/4" box would have made it stronger than it ever was. Although much more difficult to change down the road.

I have torque axles on my 14k GN trailer and when it is loaded close to weight rating the connected axel has a flex to it, similar to round spring axles, I could be wrong but I would think that that flex would bend the axle at the notch in the axle housing, only on light weight trailers 1500 lb spindles have I seen weld on

They are probably using something like this which is different then what yours and mine is Timbren Axle-Less Trailer Suspension System with Hubs - 4 on 4 - Regular Tires - 2,000 lbs Timbren Trailer Suspension A20RS440

If you look at the dexter axle video Dexter Torflex® Suspension Axles - YouTube
you can see the axle flex

 

[jwmorris]

In the dexter video you linked to the "axle" is only about a foot in length and the flex is inside the tube as it is designed, or am I missing something?

I could add some more angle bracing to the 3x5 but I still can't see that it is needed.

in the video it is cross sectional so you can see how its made, I would think that the torque from the ends flexing spreads the load through the hole axle which I would think would twist or distort at the notch, I could be wrong and maybe the weight you plan on hauling would not be enough to distort the axel. If nothing else I would box in that notch.

Old used freon or propane tanks are good for hydraulic tanks.

Be careful with the residue and make sure they are vented.

With the bracing he added on each side of the notch, I don't think it will move.
