Engine/Transmission (1998.5 - 2002) Kdp

[JMichelson]

Over the past few weeks I helped a couple of friends tab the KDP’s on their trucks. The first one was a 98 12 valve, the second was a 98 24 valve. On both trucks we used the kit and directions from TST. The directions are very straightforward and easy to understand. Took about four hours on each truck. Time well spent in my opinion. Here’s a couple of things I learned. On the 24 valve, drain the radiator down a little and remove the upper hose. Makes getting the fan shroud out a whole lot easier. You don’t have to take the windshield washer bottle out, just unhook it from the shroud and tie it out of the way. We used a gasket on the cover of the 12 valve. They don’t make a gasket for the 24 valve, so you have to use gasket sealer. I made four guide studs to line up the cover so I didn’t mess up the sealer when installing the cover. The 12 valve was a auto. You need to pull the cover of the flywheel and hold it to get the damper bolts loose. The 24 valve was a manual, just put it in gear with the parking brake set. Here’s what we found. Neither pin had moved, no surprise there. The real eye opener after you get the cover off, was the ability to see the amount of carnage the pin would cause if it did come out. A picture doesn't do it justice. It is a project well worth the time and effort to do. I think both owners slept a little better knowing that their KDP weren’t going anywhere.

i thought cummins fixed that at some point ? if so any way to tell? #'s maybe?

DCreed,

Cummins made a stepped bore in the newer case but no one knows exactly when it began being used and there is no way to tell short of pulling the gear case cover off. If I had a 2000 yr truck I might do the KDP fix, 1999 truck and older I would absolutely do the fix.

Godspeed,
Trent

Its actually a good time to just pull your whole front end off and clean it up good including the radiator. Doing it that way I can get it all done in less than 3 hours with cleaning the radiator out good. Im not bragging about my time but rather pointing out that it is much easier done this way and the radiator gets cleaned out properly. You can also make your own KDP tab easily with an oversized washer and grinder. Be sure to use locktight on that bolt or you will gain nothing.
