Unfortunately, while removing my injection pump, I dropped the keyway into the gear case. I'm going to fish around a bit more to see if I can get it out easily, but I know I'm likely looking at timing gear cover removal. The two things I'm wondering about are:

 

- Whether or not it's necessary to replace the crank seal while you're in there

- What gasket maker people prefer to use when reinstalling the timing cover

 

I've searched quite a bit but have not found any solid answers.

 

What do you guys think?

KDP problem is from 1989 to 2001 model year Cummins engines.

Is there a link to the KDP?  Now my knees are knocking!  Is there a fix that prevents catastrophic failure?

 

Thanks

Several vendors, including sponsor DAP have KDP fix kits. This kit is from Geno's and has good instructions and is one of the cheaper kits.

Why buy a kit? Just buy a fender washer, a tube of grey silicone, and front crank seal. 

 

Take the fender washer and shape it on a grinder so it like a teardrop. Pull the bolt and install the custom tab. Install a new crank seal and re-seal your cover. Your done. 

So my question is.  Is it possible to look with a borescope and see if the plate is in place?  Go in through the breather hole. Thanks

O.K.  Thanks for that.  I appreciate it.  Now I'm new to this so I have to ask, can you remove the breather and look down in there with a bore scope or something to get a peek and see if it has been done?  I bought this second hand and I don't know what has been done.

 

Thanks

That would work excellent on a cold engine when all the oil has ran to the pan. This is an updated gearcase...

The pump gear was off by one tooth.

That is a first for me to see the pump gear off by a tooth. I know people mention that it not possible to lift the gear high enough to skip a tooth. 

I'm pretty sure he had the cover off looking for the keyway when the teeth got misaligned.  People used to bump their cam by one tooth, giving about 5* advancement on the valves and VP.  They used to swear by it.

So am I looking at more meat around the dowel pin, or just the end of the hole smaller?  Is there a casting number somewhere on the cover that allows us to tell from the outside?  Date Cut off?  Nothing that organized I assume.

I skipped a tooth when I reinstalled the gear into the case with the timing cover off. I don't see any way for that gear to skip a tooth with the cover on, VP shaft present or not.

An earlier post would confirm the cover being off if IIRC>

Look at the 2 earlier pics and you can see a difference in the covers. I never gave mine a second thought after first hearing about it.
