    ASV RC85 Issues

    Yeah it’s slightly low and I was going to add some more. Is pink coolant the same as any pink coolant? Or do I need to get more involved?

    ASV RC85 Issues

    Another dumb question but I can’t find it anywhere in my searching and it’s not in my manuals. Im probably missing it. What is the coolant spec for this machine? It’s got pink coolant in it now but I’d imagine there is a spec.

    ASV RC85 Issues

    Bringing this back from the dead so hopefully it helps someone else. I fixed my issue. Turns out the pressure relief button on the top of the quick disconnect manifold block was stuck in the down position. I had to unscrew it and tap the bottom of it against the machine to get the plunger to...

    ASV RC85 Issues

    Thank you all. The grapple cylinder doesn’t leak down. It stayed up for a week. I was talking to the local Cat dealer and they mentioned the steels in the aux switches can wear and cause the solenoid valve to drift. I’ll check pressures for the drive issue. It’s not terrible and I can...

    ASV RC85 Issues

    F311fr1 I realized in your initial response you mentioned load check valves and relief valves. I replaced the relief valve but can’t see where the check valves are. I don’t see them on the schematic. Is there a load check valve for the low flow auxiliary circuit?

    ASV RC85 Issues

    Well I replaced the relief cartridge and it made no difference. I also got a new grapple and it still falls down immediately. Is there a solenoid valve somewhere that controls pressure in the circuit? I’m sort of at a loss where to go from here.

    ASV RC85 Issues

    I put a gauge on the aux circuit today at the QD fitting. The gauge only went to 3000psi so it would bottom the gauge no problem. However as soon as I let go of the momentary switch pressure would drop right back to zero psi. I didn’t have the right fitting to test the other side but assume...

    ASV RC85 Issues

    You’re the man! Thanks! I’ll verify pilot pressures before ordering anything. I also read about people flushing out the pilots and having that fix the issue so I might try that first before spending any money. thanks again for the info and advice. I really appreciate it.

    ASV RC85 Issues

    Good to know. Thanks that’s great info, really appreciate it. Do you have a hydraulic diagram of the drive controls? The one I have doesn’t show much besides the pilot lines and joystick. Trying to identify this resolver block and how much that might cost.

    ASV RC85 Issues

    Also, if I’m reading that diagram correctly the part number 0201-649 is the relief/check valve I would need to replace to stop leak down?

    ASV RC85 Issues

    Awesome thanks! Yeah I’m not sure the cylinders are leaking. The grapple doesn’t have a lot of hours and I thought it would be unlikely both cylinders would be bad. I do have a neighbor with a skid steer and was going to try the grapple on his machine and see if I can isolate the issue to my...

    ASV RC85 Issues

    Hi All, I’ve been creeping on the forum for a while but this is my first thread. I just bought a 2006 ASV RC85. It has a couple issues that I’d like to address and am hoping some folks on here can offer advice. Issue 1: The drive controls are sometimes slow to respond. What I mean by this...
