Engine/Transmission (1994 - 1998) Another KDP question

[jbowman]

I have searched this site and others regarding the KDP issue. What I haven't been able to get a handle on is the pervasiveness of the problem. Clearly, the manufacturers aren't paying any mind to the problem.



In your opinion, how common is the problem? How often does it occur (percentage-wise)? Is this something that is bound to occur on 10% of the relevant vehicles? Higher? Lower?



Thanks!

My . 02 worth is its more common in trucks that are bombed rather than stock I would say maybe 10%, that might even be a little high. Anyone out there please corrected me if Im wrong..... Rick

In my opinion it only effects 10% or less right now but will eventually effect all, it's just a matter of miles, bombed or not. I'm no longer buying into Cummins story that some pin holes were overbored, there have just been too many failures and pins on the move for that excuse, it was a poor design that Cummins let slip though. Luckily it's easy to prevent, if a person doesn't take care of it it's his own fault when it fails.

Bill is right on the money. Bombed or not the problem is real.

pin question

with every thing that i have read concerning the pin, i was wondering if the pin can be driven back in if it has moved, by using the jig method. or do you have to remove the cover any way. an other thing, i have come crossed a bolt that looks like a molly bolt, but is used to hold the mounting brackets for the mirrors on the older Chevy's 73 to 87, it has a sealing compound on both sides of the washer part. this might eliminate the threading process in the cover. just visualize a heavy duty molly, 3/8DI x 3/4long. what do you think?

Tapping the case for a jig fix is so easy I see no reason to mess with a Molly. Occasionally a jig fix won't work due to the pin being too far out but it's no big deal. You can continue the entire fix and just use a shorter bolt to plug the hole till you have the time and gaskets to remove the cover and pound the pin in, then use the regular length bolt. In the over 40 jig fixes I've done only two had the pin too far out, both were '97s. In the over 200 fixes the NW jigs have performed I've only had reports of 5 with the pin too far out, 3 were '97and one each '96 and '98.

you have done a lot of these fixes and are the best source of knowledge, the reason that i mentioned the molly, was to get away from the metal pieces doing the tapping. this could also be sealed with extra sealant. maybe the downside of the jig might be that the pin is ready to fall out, and the drill touches the pin, and down it goes, you do the threading, and finish the job, start it and ""bingo" goes the pin-- braking the case. what a thought.
