Parts list for the pressure relief valve on the D7E shows a part number of 5S1211 for the cover. The 47A service manual depicts the servicing of an earlier part number, probably the one with a 9M6366 cover (or, so I assume - anyway, it is not the procedure for part that I have installed). The 9M and the 5S are complete redesigns. The part that I have installed is of the 5S1211 "group", which the service manual doesn't cover. I need to replace the guts of my valve, and the parts manual lists CAT Form FE55040, " Instructions for Installing Pressure Relief Valve ". Does anyone have this document in electronic form that they can share?
Maybe put up your serial number which will help narrowing down an answer for you. Message Old Magnet. I think he may be able to help here. If you haven't already joined the ACMOC I would recommend you do. Lot's of info and good people there with copious experience in the old Cats. Here's a pic of my D7E 47A.

Ah, yes... A CAT made for men - stick shift! The serial number is in my signature, but I guess that it doesn't show up on a phone screen. It's 47A3316, circa 1965-66. And, what is ACMOC?
