Passing the pin- that made me laugh!

j_martin

I was given some loctite 2 part "high strength quick set" epoxy with the claim that it was better than JB weld.

Looked up the specs, it's junque compared to JB.

Also found that true with a quick trial.

I agree with the wonders of JB Weld.

That one picture of what you JBed looks like the bolt hole broke out, was that big enough to eject, or um, "pass" the pin?

It was completely spun around the other way, so, yep, I think it could have ‘passed’ right thru there. I’m gonna pull the pan tomorrow morning and peek see what’s in there.

OVERTORQUED

Okay, so I did pull the pan yesterday... well let me rephrase that. I tried to pull the pan, but was unsuccessful at getting it down. Seems that even with a couple pieces of 2 x 4’s wedged up under the motor mounts, I could not get the motor up high enough so that the pan would clear the trans. .

The truck is sitting in my driveway... technically I’m not supposed to be doing any kind of major auto repair and I have limited tools. I think I need to trailer it to the ranch where I work and pull the motor. Since it’s got to come all the way down to where I can put the new camshaft in, I think that makes more sense.

So I will definitely update in the near future whether I find that little sucker in the pan or not. I think I see a tilt front end in that Trucks future!

How about a removable engine cross member? You know, just use some square or rectangular tubing in the middle that bolts in. You first, then I'll copy!

Once the motors out, I’m gonna check that out!

Mknittle build a removable crossmember for that very purpose, during his 2wd to 4x4 swap.
There are pictures of it somewhere in his epic build thread.

Def going to check that out. Anyone seen a tilt front end on these? I'm sure they are out there, was just curious on how they did it compared to the ideas I'm knocking around.

Mine doesn’t have a P pump, so that would be incorrect I believe...

oliver foster

It appears to happen to the P-pumped 12Vs more often than the VE pumped ones, I have noticed. That doesn't mean the VE pumped 12Vs never have the problem.

A buddy of mine and I had a conversation about it a few years ago and threw out the idea that maybe the heavier P-pumped injection pump helps rattle the KDP out more than the lighter VE pump...but that was just throwing out ideas over a beer or three in the shop.

KDP problem can effect any 6bt engine from the 91.5 IC 1st gen ( not the non-IC 1st gen’s as they have a different gear cover with a blind dowel pin boos ) all the way through to around 24v 2000 year engines. Somewhere in the early 2000’s Cummins changed up the gear housing again to a dowel pin blind hole.
Reason it effects the p-pumped engines more than not is the harmonic’s of the p7100. The pump takes quite a bit of torque to just turn over, unlike a VE or VP which is easily turned by hand.

What about the 89? Does that mean I'm safe?

Earlier today, I thought this was a cool new piece of Cummins info..
Now I am not so sure. I just pulled the timing cover off a NON intercooled 12V I have been using for parts for a few years.
I looked right at the dowel pin on the case and tapped it in a 1/4 an inch or so.

This made me remember my Crew Cab bro. out in Maine was rebuilding a '91.0 Non I/Ced motor right now for a cool '78 Crew cab that came from TX. I called and asked him. He said it buttoned that motor up yesterday and the KDP was flush with the front of the timing case on his motor before he tapped in back in.
I will keep my eyes open for this elusive different cover on other NON I/C motors from now on.
