    Splitting a JD 644J loader question!!

    This is the service truck I'm presently using to pull it apart. The knuckle boom is rated @ 11K but the swing power isn't designed to move that kind of weight. I believe this is my problem?. Your guy's thoughts??

    Splitting a JD 644J loader question!!

    John the drive line is still coupled in the rear to the trans. I think my problem is POWER!!!. I'm using my crane to lift up the counter weight and swing the rear half of the machine as well. I think it's to much for the crane to do at 1 time. It was suggested to me that I need a vehicle in back...

    Splitting a JD 644J loader question!!

    Bls your right it would be much easier but hind sight is always 20/20. I found this out after I removed the pins and undid a few hydraulic lines. My problem now is space. I have limited space in front as I have a 1070 case tractor that's disabled. So I got to pull it from the rear.

    Well that would certainly make since, but I believe it also has a brake parking on the front half. I read on the frame a notice to not over fill the park brake reservoir

    I just reviewed the upper pivot and lower pivot bearing and seal breakdown in the book and it shows only a bushing in the lower pivot bearing assembly. When I removed the lower pin the bushing fell out!!.

    Splitting a JD 644J loader question!!

    When I had the rear counterweight attached to the crane, I could telescope in and out and wiggle the back half from side to side and view the center section on both top and bottom with at least 2 to 3 inches of clearance. It didn't appear to be on a bind from the center, only the rear wheels...

    I believe most utility excavators have a Photo eye up in the monitor housing that monitors the the inside temp. If that eye is no longer functioning it will allow the temp to climb and not cool down the cab. Also check the condenser to see if the fans are keeping it cooled down. Just my 2 cents.
