Engine/Transmission (1994 - 1998) need emergency dowel pin advice

[Texas Diesel]

Situation:



Removed timing case cover to R&R the KDP. Pin was walking out but still in the case ( ), tapped pin back in the case as far as it would go. Plan was to stake the hole so the pin couldnt back out any more.



Problem:



The pin is very slightly inside of flush, no room to stake. I thought the pin was normally down in the hole



Truck needs to be back in service by Monday .



Any comments appreciated.

I'd clean the hole as thoroughly as possible, and the pin, and use the strongest Loctite available - that's what it's for...



Dunno how hard those pins are, but you MIGHT also be able to use a small punch to roughen, or "knurl" the pin's surface for a tighter fit as well...

Why don't you make a tab (that will cover the dowel) using a short piece of metal and bolting it down using the bolt on the right side of dowel pin?

When I opened up my little Cummins, I had a great looking tab made and was hot to install it. However, after driving the pin back in, I used a short punch and working around the perimeter of the dowel hole, drifted the soft aluminum over the edge of dowel pin.



I suspect this alone would have been a permanent repair, but as a little added insurance, I used brake cleaner to clean things and applied green penetrating Loctite to the dowel. I also removed, cleaned and Loctited all the bolts I could access while I was at it.



I didn't use the tab, my logic being that it would be one additional thing to come loose and wreck havoc in the near-by gears.



Good luck with which ever method you use.

Ronnie's approach should do the job nicely. Looking back, the KDP on mine had not moved at all. I would have just cleaned the area and used the green wicking Loctite. Now, every time I drive, I wonder if the bolt and tab are working loose. (all those pistons and rods and valves and thingys going up and down and round and round so fast . . . )

Solution:



I drove the pin back as far as possible, peened the hole over, made a tab based on Joe's email directions and put it all back with blue loctite.



The crack in the block side gasket was 'fixed' with black silicone worked in, so far no leaks.



Thanks for all your input.
