Engine/Transmission (1998.5 - 2002) 99 KDP fix or not?

[Oliver88]

Ok, I've read lots of old threads on when the KDP fix was supposed to not be needed anymore. I wanted to feel safe so I called TST Products to order the kit. The lady (I should have gotten her name) told me that 99 models DID NOT need the KDP fix. I know there is some debate over when the problem was fixed. Is there any way I can find out if my truck needs it or not? My truck was built in St. Louis if this helps.

Thanks,

Greg

I have a '99...

as well. I have heard on here that Cummins mixed the old gear cases and the new gear cases all the way through 1999 trucks. This means that it is the luck of the draw as to whether a particular 1999 or older truck got the old style or new style case. The old style is what was used on the 12 valve trucks and those are the ones that are most prevelant to KDP. Supposedly, the new style gear cases will not allow the Dowel to work out; the case is stepped. The new style gear case retained the same part number as the old style case, so that won't help you.



The only way to know for sure is to pull the cover off the front and take a look. If you do this, you just as well be prepared to tab or jig it when you pull the cover... you have done all the hard work by this time.



Now to make you nervous; I have heard on here of a '99 having the KDP problem and it was just as ugly as the 12 valves when it happens to them.



I have not done this on mine, but if I get a chance this summer, I might see if I can find a "jig" party and do mine... in all honesty, this probably will not happen as it is going to be a very busy summer.

I pretty much second what Rashwor said. This has been brought up before and you might want to do some searching. I would just get on the Jig list and knock it out. Taking my time and bs-ing took me under an hour - start to finish. That's cheap peace of mind if you ask me.

Good luck

I was having a piers cam installed when I got a call from AUTO WURKS Diesel and was told that my 99 had the killer pin. It was almost out when found. Just call me lucky . I did not think that the 99 had the dam pin but they showed me other wise. Best of luck.

KDP Jig

Get on the Jig List! I did mine at a bomb party & I'm glad I did. I sleep great knowing the KDP has been put to bed. Now the VP44, 47RE, and the#53 Block are another thing. PM "illflem" & he can get you on the "Jig" list! Good luck.

I recently purchased the TST KDP tab kit. They also knew I had a '98. 5 24v engine prior to placing my order. In fact, their installation instructions that accompany this kit have procedures listed for both the 12v and 24v engines. I also purchased a gear case gasket from Cummins Northwest... I would rather go this route as opposed to using RTV.

I purchased the gear case gasket from Cummins Nortwest for around $20. to $21. including sales tax (if memory serves). BTW, the gasket was in stock.



I purchased my KDP kit from TST although, since two items were back ordered, a follow-up Email found out just what those two items were (a tube of Mopar gray RTV and a small tube of Loctite 271 I believe). As I possessed both items, I ordered the partial kit minus the aforementioned items for a correspondingly reduced price. The full kit price is $49. 95 (if memory serves) which includes shipping.



The TST KDP kit includes:



a steel tear drop shaped tab (about 1/8" thick)



a longer replacement, flanged-head (Metric) bolt (bolts through the tab)



a tube of Mopar gray RTV



a small tube of Loctite 271 (I believe... it could be Loctite 242 as well... both would work in this particular application)



and a high quality set of color illustrated, 12v/24v installation instructions.



The highlights can be seen in the latest issue of the TDR
