    Adjust Hydraulic Pressure Relief Valve

    Just an update. I located the pressure relief valve and turned it up gradually for a total of about 1-1/2 turns. The thing is now like a new machine... throwing heavy wet snow 30 feet or more. I have no idea what pressure it is set at so I will likely get that checked out soon. Thanks for all...

    Adjust Hydraulic Pressure Relief Valve

    The machine blows snow just fine until I load it up and I hear that very pronounced "hissing" noise which I am "[I]guessing[I]" is the relief valve opening. I've drawn (or jumped) to this conclusion because when I had the flow tested I got the same "hissing" noise when the pressure maxed out at...

    Adjust Hydraulic Pressure Relief Valve

    Delmer, I guess the best course of action would be to find the high flow valve and locate the relief valve on that circuit. The easiest thing to do would be to turn up the relief valve and see if that fixes the problem... if not, then I need to look further. Cmark, So, flow will drop as...

    I understand. Thanks Tones.

    Adjust Hydraulic Pressure Relief Valve

    Tones, If a pressure relief valve is not supposed to open until 3000 psi and it opens at 2000 psi wouldn't the only cause be either too low a setting or a faulty relief valve. I would think that regardless of leakage or a worn pump that the valve should not open until the system builds pressure...

    Adjust Hydraulic Pressure Relief Valve

    The hoses and couplers are factory so I am guessing they are big enough. The flow was measured by disconnecting the hoses from the hydraulic motor on the blower and putting the feed in one end of the flow meter and the return hose on the other end of the flow meter. When the meter was wide open...

    Adjust Hydraulic Pressure Relief Valve

    Thanks Huntoon. I gave you the flow in "litres" per minute. 90 litres per minute is actually just under 24 U.S. gallons per minute. 24*2785/1714 = 39 horsepower (If I understand correctly). The machine is over 50 h.p.

    Adjust Hydraulic Pressure Relief Valve

    Recently purchased a used JCB 1CX. I attached a snowblower to the high flow circuit of the machine and it does not perform as one would expect. The blower calls for 55 lpm. From the specs I can locate it appears that the displacement rating for the high flow circuit on the machine is 90 lpm @...

    Just an update in case anyone was wondering.... I purchased the new pressure switch ($300 cdn) and installed it. Float circuit has been working fine ever since. Thank You all for your input!!

    Sorry for the late reply. Been on holidays. I ordered a new pressure switch as I am quite confident that is the float problem. I will let you know. On another topic though... Hooked up my snowblower today for the first time and all seems to work well except I cannot lift or tilt with the loader...

    Fred, Your understanding of how that circuit works is exactly the way I see it. Yes it is a 3 position switch and functions as you described it. You are also correct when you say "it is always possible that you have more than one fault", because as it turns out... that is the case. I found at...

    JCB 1CX/208 Newbie

    Thanks for your advice guys. I tend to agree with Fred that the pressure switch creates the loop back needed to hold the relay. However, even though I was able to get the bucket into float mode a couple of times by holding the button down, it is not consistent. I may go press the button now and...

    Here is a wiring Schematic of the float switch. Can you tell me from this how it should work? Maybe the schematic is not for my exact machine....?

    JCB 1CX/208 Newbie

    I only just bought the machine and the float did not work from day 1. Once I swapped out the relay I can get it to work but I have to hold the rocker switch down. When I let it go the rocker switch pops back up and the float turns off. The wiring diagram says the relay is a latching relay. It is...

    JCB 1CX/208 Newbie

    When Pin 87 is energized by pressing the float rocker switch, must it stay energized to hold the contacts closed in the relay or need it only be energized for a second to close the contacts. I ask because pin 87 is only energized if I hold the float switch down, as soon as I take my finger off...
