Another failed oil cooler seal

[ranchhopper]

After going over my 813 this morning trying to find a cause for the minor rise in coolant temp yesterday I found the problem. I drained out all the black antifreeze this morning and am looking for the P/N for the oil cooler seals I have been all over the old threads and five ton spread sheet and no P/Ns. I got some numbers off the TMs but they were dead ends Im running out of time trying to get this thing back together for a parade tomorrow Im committed to any help would be appreciated.

Thanks I had those written down in my research the O-rings didnt look bad so just to be sure Im going to take the cooler into the radiator shop and have it pressure tested. I dont want to get it all back together just to have a leaking cooler It sucked in a gallon of oil out of the crankcase in less than five hours I would think I would be able to see a crack in the O-ring they were still relatively pliable too I will call memphis equipment or white owl for the seal kit monday.

If you have it apart might as well replace all the seals, cheap insurance. Good luck !

I will replace the seals all new while its apart got everything painted up while the parts are off the truck.
