2nd Gen Non-Engine/Transmission Cummins KDP fix

[Kalaehina]

Did anyone have a Cummins dealer do their KDP fix on your engine? Do they do this? I think I'm hearing "that" sound from my engine, been for a while and now all this KDP talk has started to concern me, but I don't have the time or resources and full confidence to do this job. There's a Cummins dealer 5 minutes away from my house and if they did it that would be perfect, I know it would probably be costly, but can't be nearly as expensive as what could happen right? Thanks in advance.

Yes they do. My friend blew his out through the side at 102,000 and the cummins/peterbuilt/kenworth dealer did it for him. But they did it in their own sweet time. Never knew the kdp to make any sounds until it let go and then most of the time the driver still doesn't know until the oil leak shows up on the ground. The jig is so easy that anyone can do it. Even if you have to pull the gear case cover to knock it back in and tab it, it is easy, should be able to do in in a saturday on the weekend, very easy. Good luck.

I don't think the Cummins fix is nearly as good as either the washer tab or the jig.

A local member had the TAB Fix done at a "stealer" around here. I think they charged him $200-$250.

So is this something my stealer should know about? Would they know what I'm talking about if I called them? And is it Cummins or dealer? Or really no difference?

I would guess most dealers have no idea what the KDP issue is. The service manager at the local delaer here is a TDR member, therefore he knew of the KDP issue.

Form letter from Cummins on the KDP

"The timing pin diameter from the supplier and the hole drilled for the pin, are designed to be 'press fit' dimensions. In some rare cases, the supplied timing pin dimension and the drilled hole dimension, may not provide the correct 'press fit'. During assembly line manufacturing, it is impossible to determine the amount of 'press fit' between the pin and the drilled hole, once the pin is installed into the bore.



A few of the pins have not had the correct 'press fit' in the drilled hole and have worked out of the hole. This does cause extensive damage to the gears and gear cover. The percentage of failure is very, very low and did not justify a major recall campaign of all engines. If an unexpected failure should occur during the warranty period of the engine, the repair will be handled under normal warranty practices.



Early in 1998 the gear cover was changed to a 'blind hole' design, which would not let the dowel pin move out of the bore. If you have a great fear of this pin coming out, we suggest discussing this issue with your local Dodge dealer or Cummins distributor, to determine the appropriate action in each situation.



The pin itself can be replaced if desired or Locktite can be used to hold it in place, without having to replace the pin or gear housing assembly.



Inspection and securing of the timing pin:



1. Remove the damper, pulley and gear cover from front of engine.



2. Tap on the dowel pin with a flat punch to insure that it is seated in the bore.



3. Clean all the oil from area with solvent and dry completely.



4. Apply some wicking type Locktite on the dowel pin and housing and let the Locktite cure.



5. Reinstall the cover with a new seal and gasket.



6. Reinstall damper and pulley.



We hope this helps you understand the dowel issue better. "

OK think I'm going with the jig method, stayed up all night researching this topic, not as intimidating as it seemed.
