View Full Version : Do these Cummins pictures show the presence or absence of the KDP?

Long story short: I have a project powered by an 8.3. I'm trying to determine if the 8.3's have the same KDP issue that 5.9's do - some engines seem to have it, but I'm not sure if they all do. I finally found a picture of an 8.3 with the timing cover off, as seen in this ebay auction:

http://cgi.ebay.com/ebaymotors/CUMMINS-8-3-LITRE-ENGINE-PARTS-/130532097271?pt=Motors_Car_Truck_Parts_Accessories&hash=item1e6451bcf7#ht_500wt_924

If you know the KDP issue, can you determine from these pictures if this engine has a KDP?

Thanks
Bob

I can't tell from the pictures. Maybe Starnes can chime in and enlighten us.

Did the KDP mod on my dad's 5.9 and I can't see enough from those photos to see if there's a pin or not.

I have a couple factory service manuals for the 8.3. We use them to run some pump jacks, although they have been converted to use spark plugs and run on natural gas from the well head. The physical motor is the same. Give me a day or two if you don't get an answer by then and I will see if my books say anything or show pics. :beer:

Is the front cover and pin location the same as a 5.9? If so, I have a jig and the necessary tools and parts to install a set/stop screw for the kdp without removing the timing cover. Can't tell by the ebay pic.

Tommy, Thanks for posting! I'll likely try to bribe Starnes to come to Boulder and fix it.

Starnes, name your bribe.

Or a brain apparently, since you don't need a star to post a pic.
