I thought they were all a 1-1/8" female hex. 1-1/8 is approximate as I remember. I think I ground the last one I made a little to fit deeper into the socket.
If yours is square then you might try a 3/4" drive and see if it doesn't fit well enough.
Thanks, Ill give that a try. The thing is way out in the sticks and Ill try a 3/4 when i get back up there.
I really appreciate the help
The tool list in the back of the 3T parts book shows the two hex size drain plug wrench with the change to the larger hex at 3T23647. The female hex is tapered. Here are the two sizes.

Thanks for your help.
It must have been changed out at some time because it is definately a square female plug. I will give a 3/4" drive a try and see if it works.
thanks for taking the time to respond.
Early and late plugs are the same on the 3T, just the female hex size changes. Both are flanged type and use the same 0L1124 gasket. Agreed, the Cat hex wrench is not that great a fit but does do the job.
OM, some members might like the 3/4 square plug part #, look on late D8K's final drive fill caps if you have time and post the part #, I know I got some plugs and replaced the hex plugs on my D8H, made my life easier. Seems like the D8K's I had were all square drive. They had petcocks for engine oil though
I looked up D8Kxxxx to last built and the finals level/fill plugs are the large female hex plug and gasket as the late 3T's. There is a different part number 8B6599 plug with same 0L1124 gasket used for the torque converter housing drain. It would also take a female wrench but I can't tell the shape. Maybe that's the source for 3/4"???
edit: looked up 8B6599 plug (magnetic) and it is a female square wrench pattern.
3/4" drive also appears to be correct.
The ones I bought were regular non magnetic, looked identical to the hex plug just had 3/4 instead. Thought I might have one in the shop but can’t find Edit: Best I can find online is # 0L-0827, not sure though
