Killer dowell pin

[Rustymule]

I just received the KDP jig for my 97 Dodge. we are going to do two of them on Sunday. Another buddy of mine owns a 92, Is there a problem with the dowel pin on these trucks, or is it a waste of time. I haven't heard of problems on early trucks. Thanks, Rusty Mule.

I'm not a expert on this but yes its a problem on these also seems notied if more then 250hp made more so. No i havent done mine!Yet!

From what has been posted in other threads. The first gen takes a different KDP jig also. The one you have for the 2nd gen won't work from what I have seen posted a while back. Do a search on KDP in the 1st gen section. There was some good threads not to long ago on this issue.

 

[Desperado]

I used a jig for the 2nd gen on a '91 1st gen, it does work as I ran the drill bit through the case I felt a little tick then as I ran the tap through it tapped harder then on my 2nd gen, so IMO it works. I'm not an expert though.

Hey guys,

I'm learning TONS of stuff on here... The KDP is one that worrys me. I have a 1996 3500 with 202,000 miles. I looked, hoping that the KDP had the update. No such luck. Where do I get a hold of this jig? I know a few people with these trucks and probably haven't had it done.



thanx

on the cpff jig there is enuff slop in the holes that you can use the same jig on both 1st and 2nd gen. [cover bolts holding jig in place have different spacing tween 1st and 2nd] since pin is in slightly different location between 1st and 2nd the retaining set screw doesnt hit it directly, but is making contact towards the side of the pin. harolds jig is specif to 1st or 2nd gen and makes direct contact with the pin. either method is good enuff to retain the dowell pin. with the set screw against it it aint goin anywhere.



harold bowers makes these kdp jigs for 1st and 2nd gens. he is getting 29. 95 for the basic jig which has jig, 2 bushings, 2 bits, 3 set screws, and depth stop. the deluxe jig kit has jig, 2 bushings, 2 bits, depthstop, air regulator/presurizer device to keep shavings out of engine, t handle allen wrench, t handle ratcheting wrench, tap, 10set screws, red locktite, detailed instructions, stickers to apply to let future owner know rig had the kdp fix done. basicly everything cept the drill, the fanhub wrench, the aircompressor, and the guy to do the job. it goes for 69. 95



one advantage harolds jig has over the cpff is the angle of the hole, if the pin has backed out somewhat you can still tap it back into place w/ a punch. no need to remover the cover

Thanks

I'll get in contact with him to buy a kit. I have been told I was next in line for one of kits going around for the last few months.

I used CPFF KDP Jig on my 93 no problems, everything worked fine. It is a good feeling that the pin cannot go anywhere.

WHAT is this KDP thing all about? I have no idea is it something I need to do? to my service truck Im building?

thanks

It is a dowl pin located at the broken place on the timing cover (pic posted above). For some reason it likes to work its way out of the hole and fall into the timing gears. The bad part is it takes out a timing cover most of the time when it does come out.

 

[Joseph Donnelly]

The pin can come out. The hole for the pin is deeper than on second gen, but does not have a restriction collar like Cummins went to in 1999l.



Also the bolts inside the gear case that hold it to the block can come out; they don't have any factory sealer on them to help retain them like post-1996 engines usually do.

JStoll,

Take a look at the following.

So what do you have to do to get a kit so I can do this repair?

I'm a little nervous having 202,000 miles on my truck!

I just finished using the "Harold's" style jig this weekend and must say it was extremely easy task. Like what was said earlier, once the hole is drilled you can see the KDP and place a punch on it to drive it in if it has moved any.

Did you buy the jig?? Where did you get it????

I got tired of waiting on some JIG PIG'S! managed to borrow it from a guy in N. Virginia. Muddymess posted above all the info on the jig including Harold's e mail and phone. His jig worked just fine for me. Only problem I had was getting the plug started on a 45 degree angle. Solved that real fast by re-installing the jig and then started the plug into the threads. All and all took about 1 1/2 hours to do.

The bolts were loose on my truck that hold the gear case on. The KDP was in but I reached in adn that one bolt was backing out by hand. This may have been what caused my problems For such a good engine, it was awful bad engineering that they would have quality ruined by something that simple. Oh well... If you haven't fixed it yet, you'd better fix it rather than being sorry. Used engines arent cheap.
