    700H trouble code

    I just looked at the number and it shows that potentiameter to be used in several spots on this machine. I will try to swap the sensor with another one and see if I get a different fault code.

    700H trouble code

    I have a customer with a 700H S#915091. This dozer sits in the middle of a ranch and rats have done some major damage. I removed harness and repaired it and reinstalled. Now I am showing a F358(B1 Decel Sensor) I checked voltage in TCU to find 1900mv at idle and 2700mv at WOT. The kicker is if I...

    I'm still getting to the forward low section of the calibration can I get the 4 failed codes for both pumps. At this point I am wondering if this is more of a computer issue.

    2000 650h lgp

    My email is krauseb24@gmail.com. I double checked and null and pcp adjustment. Everything seemed right. In the DIAG screen both the pumps show 0 millivolts all other functions show values. These were measurments taken at wide open throttle. On the left pump millivolts Speed 2 and forward was...

    2000 650h lgp

    Checked fspd and rspd and set them to med. I adjusted the motors to 3400 rpm. I tryed calibration and it failed with a f3a7. I tryed it again and it went through the low track spd part and the tcu said save and froze. I pushed and held all the buttons but nothing changed. I cut the key and...

    2000 650h lgp

    Both my motor speeds we're about 1800 RPM with the pump fully stroked and in Speed 3 the codes I got the first 3 attempts at a calibration are F3D7, F3E7, F3N1, F3M1. I got these before I got to the track speed part. The last part I got F3C8 and F3D8. I increased motor speeds to 2300 RPM...

    2000 650h lgp

    Okay got back to the Dozer. Check the PCP and they were all in spec. Now during the motor adjustment the manual gives 2 specs. Both say to use a test harness that will supply 5 volts to the PCP. My question is do I ignore the lower-spec and go with the Higher One with Speed 3 and wide open...

    Alright guys here's the story. A friend of mine asked me to work on his bulldozer and I agreed. I am a tractor mechanic and have never work on a bulldozer before. So we bought the service manual and the operation and test manual. He felt a pretty bad vibration and heard a loud pop. He knows when...
