International Harvester 885xl 4x4 yr 1982

[885XL]

Hi all,looking for some guidance on the two quick release spools on rear of my tractor,when spool lever inside cab is operated to open and shut a door on a topper,the quick release spool on left had side just holds oil pressure,even if the lever in cab with tractor turned off,is lifted up and down,but if I undo the quick release coupling the Hydraulic arms will drop lower ,then tighten coupling back up,I can insert the mowers Hydraulic pipe easy as the one on the right hand side.any help would be great.

Photos please

Hi thankyou for looking in,I’ll take pictures tomorrow of the rear of tractor tomorrow after work.

Worn couplings on tractor or topper ??

How many spools are on the tractor? If there are 2, are you sure you have them hooked up properly.
I think they used to be side by side on the old internationals, not directly above and below like a Ford.
For inserting pipes, push the spool lever forward into float, as there may be pressure in the pipe you are inserting.

Wrong connections used or worn couplings.

Good evening to you all,thankyou for replying to my problems,I’ve taken two photos,one showing 2 x yellow arrows pointing out 2x New quick release couplings,and the other picture showing the two feed pipes feeding the quick release couplings,but the nut,,blue arrow,,is this like a relief valve?as I’ve said undo the quick release on the left hand side,it’s like all pressure is out,tighten back up,start tractor up again,and wow tractor sounds great,like it’s not working! ?.

Have you got a loader fitted? In your second photo by the blue arrow one oultet from the spool looks to have some sort of a Tee setup brazed in and a pipe leading somehwere? What is that? Also what is the pipe looping up behind the QRC plate?

Has it only got the one spool lever in cab? If so does it move back, centralise, move forward and then forward a little bit more into a detent and stay there? That would be a float position

Hi,the tee has always been there,nothing to do with main problems,I have one spool in cab,I can plug in hedge trimmer in the right hand quick release with the spool lever in the up position locked,and trimmers return plug in the return quick release which is in centre of the two LH and RH quick releases.and that is how the loader works as well,it’s the left hand quick release coupling that’s the problem,with spanner undo from pipe behind plate it’s fitted to oil will weep out,do it back up again,start tractor,can’t put Hydraulic pipe back in it? Pressure! ? I’m wondering if it’s something to do with lever in cab not working properly,,spool lever that is.hope this makes sense to you.thankyou.

Looks like you have one double acting spool. Moving lever back will pressurise one coupling and moving it forward the other. It should move forward a bit more into a float setting (like a dump) if it’s got one. Otherwise only way to de pressurise is switch engine off and wiggle lever both ways.

As an experiment, with nothing connected you shoukd feel and hear the tractor labouring when you find the two positions on the lever as it will be blowing the reilef valve and pumping back to tank as the oil has no where to go.

Have you ever used it to tip a trailer?

Is the fitting that is giving the problem, the one that goes to the front of the spool block with the tee fitting? Thinking it may be back pressure from something.
Does the pipe go in with the tractor stopped and the lever all the way forward in float?
What then happens when you start it up?

Hi,I’ll check which pipe it is tomorrow,with tractor turned off ,wiggle lever in cab up and down,still has pressure,after a couple of hrs,it will allow me to insert Hydraulic pipe leaving tractor turned off.you mentioned back pressure that’s what I’m thinking ,,but how.would it be because I’ve never used it?only the right hand one.thankyou.

Thank you for looking in,ok I will try your experiment later tomorrow,thankyou,used a trailer, yes but remembering placing trailer pipe in the right hand quick release coupling,,so obviously lever in cab fully up(fully down pressure left hand quick release coupling) but remember pushing lever down too bring trailer bed down from tipped was making tractor sound like it’s working? Hope you can make sense of this,thankyou.

If the tractor was labouring when trailer was coming back down then either you’re not finding the float position or it hasn’t got one.

I think all spool slices on XLs had float position, so 4 positions. so starting from the stop position.
1 up and 2 down. if the control rods are out of adjustment then some of the positions would be lost.
in their day very good tractors , had 4 xl's in the early eighties.

Hi,I’ve tried your experiment,started tractor up,No Hydraulic pipes plugged in,pulled up spool lever in cab,pressure on,tractor labouring,pushed spool lever fully down,pressure on,tractor labouring,left lever in middle tractor running ok.If i had air in the Hydraulic system how would I get air out of it?ny ideas would be appreciated.

as mentioned above, sounds like you have no float, maybe the rod is out of adjustment. There is a detent, so you will have to push it forward past the “click” point and It should stay forward.

I don’t understand your reply above. The fitting is pressurised every time you push the lever forward, this is the labouring of the engine you hear.
When you pull the lever to operate the right spool, pressure should be released from the left, and it is connected to the return.

When I mentioned back pressure, I meant pressure from the pipe on the tee fitting.
As mentioned before, where does this pipe go to?
You mentioned this has nothing to do with the problem, but if you have never used the left hand fitting, then how do you know.

Hi,this is the problem,pressure is staying in the left hand coupling,tractor turned off,in cab spool lever pulled up and down a few times,to release pressure,pull out the right hand quick release,that’s good,push it back in again great done,obviously still no pressure in spools,go to the left hand side pull out pipe,the plug in,no way,still pressure inside? Hope you’re able to understand now,thankyou for your time.

If you stop the tractor, push the lever fully forward and leave it there, can you remove and reinsert the pipe into the coupling? (Don’t start the tractor)

Does the implement pipe have pressure on it? i.e is it holding a ram up, or something against a spring.
To make sure it’s not an issue with the implement or pipes, have you tried swapping the pipes round?
