    Cat 308bsr hydraulics locked out electrically I think

    It turns out this Fault Code is a open circuit on the Potentiometer located at the knuckle of the boom/stick. The plug was loose. I cleaned it up and reconnected the plug and it cleared the fault code. Apparently these Japanese grey iron units have this as a safety feature to lock the movement...

    Cat 308bsr hydraulics locked out electrically I think

    Here is a pic of the console with error message. Any help on this error message would be greatly appreciated. When you first start the machine I have green lights on the console and then the error message comes on and all the lights go out on the console except for the E-22. It appears to lock out.

    Cat 308bsr hydraulics locked out electrically I think

    Hello all, I have a 308Bsr Excavator and I am getting a E-22 error on the digital display. Can anyone tell me what this error is? The machine's stick/boom will not function. Bucket Curls, machine swivels and moves but has no stick/boom movement. I understand this is a grey machine from Japan and...

    1987 D6H hydraulics getting hot and all the gauges don't work

    6FC-00369 I would really like to check the high pressure at the hydraulic control valve to see if it is set to low. Can anyone tell me how to do that? Where and how do you check the low pressure?

    1987 D6H hydraulics getting hot and all the gauges don't work

    I am being told by the local Cat dealer that this unit does not have a hydraulic oil cooler. I will search around the radiator but was told that this serial numbered unit did not come with one and the oil is cooled thru the hydraulic oil resovoir. What is a typical hydraulic oil operating range...

    1987 D6H hydraulics getting hot and all the gauges don't work

    Last night I ran it for a few hours again and strapped a Fluke digital thermometer right on the pressure line to the top of the hydraulic control valves. Was running between 150 and 165 degrees. If you stop, raise and lower the blade a dozen or more times in a row, you can get the temperature to...

    1987 D6H hydraulics getting hot and all the gauges don't work

    I pulled the floor cover in the cab and found loose and wet clamps on the suction side of the pump. Bought and installed heavy duty stainless clamps and the air bubbles in the oil seemed to clear up. I am still having an issue with the hydraulics getting hot. This is weird, I can pull the cap...

    1987 D6H hydraulics getting hot and all the gauges don't work

    I found a broken wire (power) to all the gauges. They all work now. I torqued the pass thru bolts to 85 ft lbs per Caterpillar's recommendation and ran for awhile. I cleaned the vent on the hydraulic tank thinking it might be plugged. Leak stopped but oil still getting very hot. I took the cap...

    1987 D6H hydraulics getting hot and all the gauges don't work

    All, Can anyone help me try to figure out what is going on with a D6H that I just purchased. It shifts fine. The hydraulics all work fine but when the machine gets hot it start pouring oil out of the spool valve. Can't tell exactly where. I have taken the spool valve out and replaced all the...
