sdeeter19555 Ok, I've been researching this some...

Getting things apart, no surprises, nothing jumps out as difficult. Tabbing the pin, easy. Putting it together, nothing odd.

Where are the other bolts for the timing case (under the timing cover) that need loctite? Am I correct in assuming I need to spin the crank to access those bolts through the "access" holes in the timing gears?

And, because I watched it done both ways, is the crank seal indexed with the installer from the front or the back of the cover???? I see its punched to the back, installed from the back, but is it indexed from the front or the back? Or doesn't it make a difference?

sdeeter19555 Well, since that is the case; I just ordered the TST KDP kit from Geno's; I'll tackle that whenever it comes in...

I would change the timing cover gasket and front main seal when you get in there. Better than pulling it off later for an oil leak

82f100swb My 92 the PO paid to have tabbed, but it wasn't. It spit it out. My Fummins the parts were purchased, but it was never done, came into my posession with a new timing case... Thats 2/3 when it comes to 12V's I have owned that spit it out. I would not trust it to stay put.

sdeeter19555 Well, I did determine that an inspection camera (even a small one) won't get between the gear and cover...although I did see some things, just nothing useful.

At least it was clean in there...

My understanding with this replacement engine is that it was bought from a yard in Texas that specializes in Cummins, my guess is it was bought as a long block and they bolted all the accessories from the original engine onto it (that's why my turbo looked like it had 400k miles on it).

My point is that maybe they tabbed it before they installed it...not much other reason to be under that cover except for a seal leak. It would be nice to know before I go to the trouble to tear the front of it apart...

I do plan to stamp an aluminum tag with KDP KILLED and a date and install it under one of the cover bolts, for the next guy...

sdeeter19555 Just throwing this out there...to see if anyone has tried this before I waste the time.

I'm thinking the original engine in this truck was probably a KDP failure. The timing case appears to have been removed at some point. What is the likelihood they tabbed the KDP on the replacement engine to prevent a repeated event?

Has anyone taken and inspection camera and tried going in through the oil fill hole? It would take five minutes to remove the oil fill tube, then you theoretically could snake a camera back into the cover? My only thought is if there isn't enough room between the case and the gears to fit a 3/8" camera?

Thoughts? It will be a couple weeks before I'm back at this thing, but I'm scheming now to get my plan together.

monsoon-mech its not a milage thing.. its a "just how tight is the pin on my exact particular truck" thing,

9297oldram I agree do it it's cheaper and alot less work then repairing it if it would fall out.

daword2011 People do it for the peace of mind, there's no way to know when or if it'll ever happen. I've seen trucks with 500k miles that the KDP hasn't moved an bit. And the truck I have had the pin fall out at 70k miles. Personally, if you're ever anywhere near there (rad work, fan clutch, injector pump, front main seal, etc) I would just do it. For the cost of the part, it's worth the peace of mind.
