    140m DIFF LOCK

    I’m having some trouble with my 140m B9d1908 13415 hrs. Hoping ifor some input from you guys. Something in the drive train(best I can tell) is making the machine not ride as smooth as it should when working along with extremely rough up and down shifts.

    Grade changes when I turn around

Sitech has always thought it was something to do with 2d sensor calibration but recalibration seems to have no affect. Grade is very consistent when it’s missing.

    140m sluggish(hesitating) lift

    What would be the best way to show them this problem so they can get it fixed. A lot of the time the mechanics seem like they are clueless as to how a machine is supposed to operate. Some have the opinion if it moves that means nothing is wrong with it.

    140m sluggish(hesitating) lift

    When it comes to showing cat this problem and getting it fixed. Do you agree it shouldn’t make any difference in the response of the lift cylinders whether I’m using the ripper function or not. In other words the lift response should be the same regardless. Right?

    140m fan noise

    Most of our 140m’s never get hydraulics over 160 degrees..so it’s running pretty warm. If anyone has dealt with this problem let me know please. Thanks

    140m fan noise

    I understand that the fan works on demand speeds up as needed. This whining hydraulic noise isn’t normal. And the high temp isn’t normal.
