I took the front cover off my 2002 24v today. After taking everything off the front and once the cover was off I did a good inspection of everything in the case. My 02 did not have the updated timing case, it had the older version. There was no step in the hole to prevent the dowel pin from coming out. Also found a bolt holding the case to the block lose. Tabbed the pin, pulled out each bolt one at a time and used red loctite on them. Torqued everything down to besure nothing will back out. Steamed the radiator, installed a new crank seal, new upper and lower radiator hoses, and belt tensioner. All said and done, it took exactly 3 hrs from start to finish to do the job. Been getting faster at the KDP job the more me and a buddy do them. Checked for leaks before leaving his shop and after I got home. Everything is good!

Got a few pics for those who never have done a KDP to look at. I think any newbie with a little mechanical knowledge could do this on their own. I've done a few now and wouldn't mind doing more for others.

The parts all off the truck

 

Nice job Matt. Maybe Iker will put this in the wiki section?

 

Thanks Tim!

 

No Kidding. Definately WIKI material.

Why did you put on a new tensioner? Was the old one bad, or just because you had access?

Did you take the auxiliary battery cable off?

Thanks for the info Matt.

Great write up!!

 

I wish I got a shot of the whole engine bay with everything apart. I did unbolt the battery cable on the top of the rad and moved it out of the way. The old tensioner was getting bad. Bearing was going out in it. Put the new one on and I'm going to find a bearing for the old one and keep it as a spare.

To note, the overflow tank comes off pretty easy, the washer fluid tank is a little hard to get off the shroud. Had to jam a long screwdriver in between it and the shroud. You'll see what I mean when you get to that part.

To get my fan lose, I used my extremly cheap snap on Cummins fan wrench and a large pipe wrench on the pulley to break it lose. It's lefthand threaded on the fan nut.

 

so how many 24v trucks are running around with the kdp as a issue? i thought this was only a issue on the 12v trucks?

 

It's hit or miss. Some trucks have an updated case that has a lip in it to keep the pin from falling out and some don't. Only way to tell is to open it up and look. There was a thread on one of the forums, can't remember if it was here or another one... but anyways the poster had an 02 24v without the updated case, his KDP fell out and cracked the case. I've read of a few 01's with the issue too. Now some owners have opened up their case and found they have the version where the pin cannot fall out. It's not only limited to 12v trucks.

 

tougher question..
is to possible to inspect these through the vent cover after its been removed. such as when changing out the VP44?

I'm asking because, I would like to know if I have a problem without taking everything apart..

I bought my truck used to it might have been fixed before me..

I would imagine if you have a bore scope you probably could check and see through the hole.

 

Thank you for posting that ! I have literally got into arguements on here with guys that say that all 24Vs have the updated cover. Excellent article BTW.

 

Thanks DR. I didn't believe it at first until I did a little research, definately evenyone with a 12v and 24v should check their trucks. Alot of owners seem to think it's a 12v only problem.

 

One thing, though it is too late for yours, you should probably use Loctite Blue ( 242) as you would never, ever get those small bolts out with Red.

 

I've used red loctite in the past on the inside bolts that hold the case to the block. It's recomended to use red on them. The outer bolts that hold the cover on just get torqued to spec. I've used red in alot of applications and never have a problem breaking large or small bolt lose. I don't understand why Cummins never used drilled bolts with safety wire inside the timing case. It would keep them from backing out and falling into the gears. The primemovers I work on, all the internal bolts are wired to prevent them from backing out and falling into gears

 

My cover is leaking and I need to get it fixed and the kdp checked on the truck in my sig.

both diesel shops I have had do work for me tell me the "head has to be pulled" and it is a full day job, I tell them it's not but they don't believe me

I've been trying to find someone in Texas to fix mine but I hate to pay more than what the jobs really worth

wish you were in Tx
