QUICK-ON TOOL

[J_J]

Here is a tool for those QD's that are difficult to connect and un-connect.

At 4:09 you can watch the operator use the QUICK-ON tool. Might save some people some frustration.

R U planning to import these?

No, that was for someone to make their own tool, or just purchase one for those that are weak in the hand.

Actually, my QD have the two way sleeve, either push or pull.

If the fluid does expand, I push the male fitting on a hard flat surface and it usually releases the pressure.

Before I figured out the two-way alternative, I would gladly have bought one, but the dealers all seem to be in Deutchland.

My QDs, too, are two-way, as we discussed in another post ...however, the two-ways only work if mounted (bulkhead or bracket), while the tool works for free-standing ones, too (and not so clear how it would work on mounted ones, depending on the clearance).

Incidentally, in the videos some of the sleeves seemed to require a twist or two, no? I had never come across such.

Joel, I don't mean to cast aspersions on J_J's post because the tools are certainly a solution. However, that tool is bound to be very expensive and so big it may not fit into the space needed for loader quick connects. On my tractor with four fittings stacked closely together in a tight spot, that tool would surely be cumbersome. I think the easiest way to ensure your fittings never build up pressure is to buy matching male or female quick connects and put them on the attachment fittings when you remove it. You'll lose a couple of drops of fluid, but that can be minimized by bungeeing/tying the fittings pointed upwards. Remove the fittings and put them into a ziploc bag when not in use.

That tool would be nice on my track loader and tractor when changing grapples and 4 in 1 buckets. At different times I had state and regional records for powerlifting and I still workout with free weights. Still, at times it seems impossible to remove or couple some of those fittings and I'm certainly not weak in the hand. Actually, I must be Horrible Freight's worst nightmare when it comes to hand tools. Generally, I can break their tools without much problem since they are not made from what I'd call quality steel.

I always carry extra hoses with me. I've seem to be really lucky at snagging hoses too. I really love changing them while standing in the middle of a super thick area of thorns with a nice coating of hydraulic fluid all over me. My, my, that makes me so happy and I come up with some words not fit to use in public; but that generally doesn't happen until I get some good blood flowing on everything as well and am trying to clean a wound well enough with rags to SuperGlue it together so I don't have to stop and get stitches.

On skid steers and track loaders you have no hydraulics with the engine off, so it's impossible to relieve the pressure on those fittings like you can on a tractor. It's a safety feature. I've tried to lower the bar and turn the key on and then move the joystick to relieve pressure, but that doesn't work either. I've never had any issue on a tractor. You just shut the engine off and cycle each cylinder several times until the pressures are equalized. You can't do that on the bigger skid steer fittings and they're a real bugger at times.

I don't know anyone who has a problem disconnecting on a CUT. The problem on our CUTs normally comes when we remove the loader or a grapple and leave it sitting out in the sun to build up extreme pressures inside the hoses. Having an open fitting installed ensures that pressure never builds. I'm sure larger 3/4" and 1" fittings on large equipment would be well served with a special squeezing tool just for normal operation.

Reminds me of the way a caulking gun works, could maybe mod one to use on couplers.

Yes, it seems the sleeve has a cutout in it to accept a detent ball which helps lock the sleeve when turned- can be seen during the demo of the display stand use of the tool. Probably some industrial use application?
