hydraulic connection

[bludorbronc]

i had trouble hooking up hoses to my auxilary couplers, easier to hook than unhook,my dad being an old farmer, looked at my delima and told me that the female fitting had an o ring behind it and that you take a wrench and unscrew the outer side part of the fitting and that let the inside balls roll back and you inserted the male hose fitting and with wrench or hand screwed the female back tight and it held the hose tight. so the reverse can release the mating hose with no effort. now its easy.

Did you try relieving the pressure in the system before un-hooking? If it didn't have an O ring, it would leak....
Is the fitting worn? they should un-couple and re-couple pretty easily when there is no pressure behind them.

i wiggled to arm back and forth, other than that how do you relieve pressure?

Thats exactly how i do it too... Shut the machine down, then wiggle the right stick then its good to go.

Toggle the switch back and forth like tazza says but just make sure that you turn the ignition is on but not with the engine running, you need to do this to allow the pressure to release past the aux solnoids. Although I did find a few machines and certian attachments (usually grapples) are harder to release than others like a sweeper or brush cat.

The couplers are “Quick Release” and do not require a wrenching. If they do, no matter what type they are, there is something wrong and it's time to change them.

Depending on the model you have, some would release the pressure by holding the key backwards when shutting down engine. The G series had a button in the dash to release the pressure. If you try what andrcurrie says, make sure you turn key on, not start engine, 'activate' hydraulics with dash switch, then toggle the thumb switch. All the above are assuming that your model has electric over hydraulic control. If it's linkage control, do like Tazza says and wiggle the right lever side to side, with the engine off.

And if all the above fails, you can lossen the hose where it meets the couplers and let a few onces of oil escape. That sould only be necessary on vary rare instances though. I'd do this b4 taking the coupler 1/2 apart.
