    D6M trans calibration issue

    I took good notes. 6 wires including the solenoid return. Compared each wire with the others. Hopefully I'll know more tomorrow. Thanks for responding Nige!

    D6M trans calibration issue

    with J1 and J2 unplugged. I checked for continuity between the "hot" wires for each solenoid. I have around 20 ohms. The manual says no less than 5k... yet, I have no active codes. according to that, the harness is shorted. I disconnected the xmsn harness at the rear of the machine and checked...

    D6M trans calibration issue

    SN 3WN1059 Trying to calibrated transmission after rebuild. In certain gears engagement pressure can be set fine. In others the machine will try to move and calibration is stopped by ECM. It seems to shift fine though. I am going to check for a short in the harness after I post this. I've got...

    Cat prv 350l calibration....

    Thats awesome. One of my friends found he could unplug his Cat powered service truck water temp sensor for the ecm and it would never come out of cold mode then he put vise grips on his waste gate hose. Lol That one is a mess now. One all us old Cat guys love to torment but respect very much!

    Cat prv 350l calibration....

    Yes. But not only speed sensor. A very common one is Cat D6 will get a crank but no start condition. No codes. But the machine will have been sitting there long enough to be cold and water temp will show in operating range! The ambiant temp is too cold for the engine to start without switching...

    The Vantage was actually a scope and a volt meter. Was a fantastic tool!

    Cat prv 350l calibration....

    That Vantage was a graphing meter but it was crazy fast and could catch even tiny glitches in the signal. I had an old Volvo A25C with a stupid transmission. I finally tapped into the engine speed sensor in the flywheel housing. The signal looked like a small child got ahold of a ball pint pen...

    Cat prv 350l calibration....

    Good sound advice TVA! I had a snapon Vantage meter when they first came out. It was great for checking sin waves. It was 4000.00 back then. No telling how much now. It of course eventually quit working and all they wanted to do was trade it for a much more expensive one. Lol.

    Cat prv 350l calibration....

    I think i said it earlier but sometimes, jumping between threads i get mixed up. Some machines will talk through one data link during calbrations and another data link during normal operation. If the "normal operation" data link is defective that could explain your problem. Ive had an ECM fail...

    Cat 325L no hydraulic power

    I've only ever had a spool fail to center caused by trash or broken centering spring.

    Cat 325L no hydraulic power

    Arm cylinder hanging sounds like main spool hung due to trash in the system. Maybe arm cylinder coming apart?

    Cat 325L no hydraulic power

    Just remembered... (There's nearly 30 years of tractor knowledge to shuffle through) I once had a trackhoe that had a plugged screen in the pilot passage in the center of the main control valve. It only let the hydraulics of one pump work. "Suckability" you should write service manuals!
