Is there anything to stop somone just using chemical metal and a a small strip of metal from the garage to tab the pin in place and replace relevent seals rather than paying for the kit, or is it particularly special?

the kit is a tab to keep it in. just research how it is installed so you understand exactly how it needs to be. it's not like your casting an engine block in your bathroom. just a simple little thing to prevent a very bad failure. i would think any backyard mechanic with metal cutting tools could fabricate it

I agree, if you look it up and see what the kit consist of, you could fabricate your own. just becareful and make sure its something that wont fall apart on you.. (that would kinda ruin the point of the whole kit...)

well use some loctite and make sure its good and snug. but ya thats the thing. if you can do it you could probably fix it much cheaper than 65. idk how much the gasket costs though

I used a coat hanger as shown in my thread in the sticky.

Also guys dont forget the timing case bolts. I had one or two finger tight, they do just as much damage.

Just make sure whatever you put in there doesn't add new ways for things to come apart. That's why I like peening. The new trucks use a tapered hole in the case for the same effect.

Never heard of the timing slipping. I have heard if the pin is not in there there is enough slop in the holes for the case to move around and the gears could come in contact with case.

No noises to warn me that something was wrong. Cruisin down the highway at 65 and a pop and it was dead. Broke about 3 teeth out of the cam gear and a couple out of pump gear and snapped the cam.

hm i coulda swore i saw that somewhere but i don't do cummins so i can't give a definite answer on it. i'm guessing gears hitting the case could wake you up a bit though

There's no problem losing the KDP as long as it doesn't get caught in the gears on the way out and the case bolts stay tight. The problem is the case bolts come loose too, as bobby mentioned. The first indication you had a problem in that area would probably be an Exxon Valdez-sized oil leak from the crankshaft seal.
