    140h grader no voltage on the transmission solenoids

    I'll have to read up on it but I'm pretty sure that these solenoids are pulse width modulated for a smooth clutch engagement. When the ecm detects a fault, (such as disconnecting a solenoid plug to check voltage) it limits the output voltage to 5 volts and stops any current flow. If you have the...

    So what's the actual problem if you don't mind me asking?

    Best way to remove old pads from chains

    We've been getting sets of tracks complete, and what I've noticed is that whoever's done the installation of the new grousers has used an oxy-torch to burn the paint, it makes it easier to get the paint off.

    Difference between sprocket on the front or on the back

    Very interesting! Bit off topic, but looks a dam side easier than Splitting Dozer and excavator tracks we usually needed a 100 ton press and occasionally a 14lb hammer too, for the sticky pins on the D9 and the 374D..

    Difference between sprocket on the front or on the back

    For working with an excavator, having your sprockets at the back is the only way to work and travel. they weren't designed to take shock loading like the idler on the other end, they're raised slightly too so they don't carry the weight of the machine. they also don't like things hitting them...

    Need some feedback about this.

    Hey Craydul, I reckon one of the best tools anyone has is communication. Be frank with the guy about the way you feel. I'm assuming you have a detailed time sheet? if not i would keep a record of the jobs and time you spend on the machines, Especially if you feel like he's taking credit for your...

    Cummins missing & puffing

    Hey Brandon, Might i also recommend that you see if your fuel tank has a drain on it.. Its possible that with 2 weeks of rain that your fuel cap (or some other nefarious reason) has somehow allowed water through and has accumulated to an unsuitable level where your separator cant handle the...

    thats it. I know there's no image for the coupler itself, but if you ask the dealer they should be able to show you one.

    750c series 2 tracking issues

    Hey there trey, I'm no expert on JD, but from what i just read about it, the track motors are driven by individual hydraulic motors and pumps. I would also like to suggest, if the charge pressure checks out, if the control system is electro-hydraulic, swapping the the plugs to the solenoids...

    Best air grease gun and tips.

    190-1670 - that's the one if i'm not mistaken.. has a steel insert, extremely durable. the 2M-2689 has a rubber insert, is smaller, but less durable and not really worth it.

    Cat D400E data link/ ECM problems.

    Its a bit deflating when you sink your teeth into a problem, only to have someone fix it on the other shift. But that's what team work is about. Glad the issue was sorted though.

    Best air grease gun and tips.

    i know its a bit late, and i haven't had the pleasure of a genuine locknlube coupler, we did get a generic coupler with the same design. works great till the face seal tears or wears out. we went through 180kg of moly grease in 3-4 weeks, withpedal pumps. keeping the couplers clean was my pet...
