MACK wrote: Series3 had heavier front axel, different brakes, few changes in hydraulic pump, hydraulic and PD oil together, dry air cleaner, belt drive power steering pump, and a few other miner changes.        MACK

Several of those were options.  I did not list the options, just the way you can tell the difference between the Series.  There are several other options, and from the looks of it they were available on all D17's.  The one that really surprised me was the Foot Accelerator, which was an option for the Industrial version.  I would think it could be put on any series if you had the parts.
