I have owned a TC33D with 7308 FEL for about two months now. I decided to take the FEL off this weekend just for the experience. Now I'm trying to reattach it and am having a problem. I can't attach one of the hydrolic connectors. I was able to attach all of them except for one (the red one).
Also, just to be clear, when I was detaching the FEL, I did relieve the hydro pressure after turning off the tractor and before disconnecting the hydro connections. I did this by moving the joystick through all of it's positions.
Has anyone else experienced this? Any advice would be appreciated!
Thanks,
Carlton

Don't have a blue tractor, but I have an Orange and a Green one.
I know this: If I take off the backhoe when it is cool and try to put it back on when it is warm, I have exactly the problem you describe.
You need to relieve the pressure in the hydraulic lines and figure out a way to depress the little check valves inside the quick connect fittings without damaging the O rings.
With the male connectors you can push real hard against a metal surface like the loader bucket. With the female fittings you may have to use a flat tipped punch and push against a hard surface.
That should solve the problem. Sometimes you only get a couple drops out but it is enough to get the couplers together ....

The solution is likely as MarkH says. Another explanation that would produce the same result is if the curl pressure was relieved before the lift. Unless the bucket is flat, relieving the lift may reload the curl circuit. I usually put the lift in float and then relieve the curl pressure.

An easier (safer?) way to unload a hydraulic circuit is to let the system itself take the excess fluid.
Sound confusing, here it is in crayon.
If the hose from the top of the 'bucket curl' cylinder is pressurized (the usual culprit because there is weight sitting on it) then connect the hose from the lower end of that cylinder to the valve in it's proper location and move the valve just slightly as if you were trying to curl the bucket up (i.e. pressurize this side a bit). It may take a little practice, but you can move the cylinder just a fraction of an inch and take the weight off that line by pressurizing the other side and forcing it up. This will allow the other side to be connected easily since it not under any pressure.
Best of luck. ....

Now Murf, it's not suppose to be that simple. It's not the way I do it, so it has to be wrong.
Just kiddin, sounds pretty simple. Myself, I just press the end of the culprit hose against the tractor frame.
Besides, once I bend over to hook the hoses up, I need to conserve every breathe ;)

There is another simple solution, but it takes a little planning ahead.
Before you disconnect the 'bucket curl' circuit shut the machine down for a minute and cycle that portion of the control valve, then disconnect that circuit. By allowing the loader to do any settling with the lines connect any fluid that needs to move does so and hopefully neither line will be pressurized when you go to put it back on.
A friend of mine uses a big block of firewood under the cross brace rather than the bucket to rest the loader on, swears it keeps the lines easy to re-connect.
I can relate to the breath thing too, even though I'm not that old last years health problems made it a fact of life. Thank goodness for A/C & HEPA air filters in cabs too...
Best of luck. ....

This happened to me once - line was under pressure because I forgot to flaten bucket before disconnecting. So...I connected the lift cylinders - lifted the bucket under power - rested bracket behind bucket on chunk of wood - shut it off - then connected it fine without a problem. Trust me without doing this - the Hulk could not have connected the lines - I could not budge the ball - not even a micron.
Try to see why the hose is pressurized - usually you can readlily deduce why the pressure is there and if you moved the valves around before disconnecting - it is probably gravity that is getting you. Take the weight off the effected portion as I described above. ....

Try lowering your pto to the lowest level possible- this will take some pressure off of the hydrolics and allow for easy replacement of hose. ....

try loosning the coupler on the red hose of the loader side to relieve the pressure,If that dosent work,you have a bad coupler,,this is a easy fix,,just get a new one!(coupler that is!) ....

I am confident that the situation is unrelated to a mechanical problem - there is probably simply a line under pressure when you are unable to reconnect the quick disconnect. ....
