Engine/Transmission (1998.5 - 2002) Cylinder Cut-Out Test

[Greenleaf]

My boss asked me to have a cylinder cut-out test performed... ... ... ... ... .



On and ISB... ... ... ... ...



Is this possible? With the VP-44. I have injector problems time to time he said it's easiest to do with the cut-out test.



He also told me that the way to adjust heavy truck brakes is to drive it in reverse and hit the brakes... ... ... ... ... ... ...



He has 31 years as a heavy maint. mechanic in the Air Force.

I'm pretty sure Cummins and Dodge dealers can shut each injector off individually on ISB's.

yes... you can command the vp44 to cut out each cylinder 1 by 1

yeah, it can be done just like the bigger cummins engines, but you will need the cummins program. (pretty cool to get an M11 to run on 1 cylinder!!!)

i tried to get an isx to run on one cylinder, but it was too cold and died. haha. it was great. i've known how to adjust air brakes since i was 17

The snap on scanner can do it also. That is how i tracked down my bad injector. You cut the cylinders one at a time. When you cut the cylinder, the engine will develop a stumble if that particular cylinder is good. When the engine runs the same with a particular cylinder on or off, you know you found the bad one.

Some air brake slack adjusters on heavy trucks are automatically adjusting, and various methods are used. On most of the automatic slack adjusters, it is not necessary to back up to get the brakes to adjust.



With the old manually adjusted air brake slack adjusters, you have to adjust them up with a 9/16" wrench, then back them off a half turn. Make sure that the locking collar pops back out too, or the slack adjuster will back itself off.



Now, if you are referring to your Dodge, and you have drum brakes in the rear (90's and 92's have drum brakes in the rear), that's a different story. The brakes will automatically adjust as a normal function of backing up and going forward, which slightly rotates the brake shoe assembly. If you routinely back out of driveways, parking spaces, etc. , you should not have to worry about it, unless the adjustment screw is rusted tight. If that occurs, the brakes will wear down to the point that you push the ends of your wheel cylinders out.
