    Deere 800C - loss of hydraulic power

    We're experiencing a strange problem with my 800C. After working it for a bit and it warms up, it starts to slow down on all hydraulic functions, including swing and travel, until after an hour or so it's so slow it only makes sense to stop digging. It's as if something is wrong with the pilot...

    Intermittent hydraulic power loss - JD 450CLC

    We're chasing an annoying problem on my 450CLC. It tends to work fine in the morning with full power to all hydraulic functions. However, it will sometimes without warning lose hydraulic power and all functions, including crawling, and will slow down as if somehow the hydraulic or pilot system...

    Aluminium hydraulic oil cooler for deere 800c / hitachi zx800

    Does anyone on here know of any aftermarket company that makes a bolt-in cooler for the 800C/ZX800? I had to replace the one in my machine late last year with a new OEM replacement, which cost over $10,000 and that has started to leak already. The problem is that these coolers are made from mild...

    Deere 450 CLC - Diesel in Radiator?!

    On checking over my Deere 450 CLC this morning my maintenance guy found the radiator had diesel in it, and the overflow bottle also had a bit of fuel in it as well. There is no fuel in the crankcase. The machine runs fine and there is no strange noises or loss of power. We've already pulled the...

    Hydraulic Pump Noise on Deere 450CLC

    I have an issue that has me stumped. My 450CLC has developed a squeal whenever the hydraulic system is under load. The machine is a 2006 model. It still has full power on all functions, it just makes a god awful noise when the oil temperature comes up and we start working the machine. It tracks...

    What's a safe operating temperature for Hydraulic oil?

    What kind of temperatures do you see on your excavators' hydraulic oil? When pushed hard, my 800 runs above 70 degrees Celcius, which I think is around 160 degrees Fahrenheit, and will go up to 78, which my operator thinks is a bit hot. Is this a safe temperature for the hydraulic oil? We only...

    Anyone heard of AMEC Buckets???

    I just bought a used stick for my 800C and it came with an "AMEC" bucket. I have never heard of them and can't find anything on the Internet. It is an very heavy duty bucket with 2" plating on the side and very thick wear bars on the bottom. It is also quite a bit taller than my Central Fab...

    Deere 800C Engine Control Motor problem

    We're having real problem with my 2006 800C. The problem is that the engine idles at very low RPM (like 500rpm) and will not speed up, as the EC Motor (step motor) will not operate the throttle cable to speed up the engine. The cable is fine and operates easily and smoothly and when manually...

    Add-A-Boot for Deere 800C

    Any of you guys on here know anyone that's using an Add-a-Boot on a larger (75-90 ton) machine? (Not the Add-a-Stick, but the fixed stick extension "boot") I have a job coming up where I need to excavate shot rock to a depth of around 34feet below the water table. I have a Deere 800CLC that has...
