Hi all. I have just purchased a new oil cooler for my Cat 312B 1998, s/n 9HR02634. It hasn't come with the 2 unions which the hydraulic pipes attach to, one at the top the other at the bottom. I can't get them off the old one as I replaced that with a non standard one just to keep it going, which is now leaking quite bad, hence the new cooler. Can anyone tell me the part number for these union or give me the size so I can get to. I can't get to the cooler as it is in the bahamas and I am in the UK. Just need to get them to take out with me when I go in a couple of weeks. Thanks in advance for any help. Malcs
