Long story short. Got a temp lay off from the dealer due to this Covid BS. Not a big deal but they revoked my SIS access. I'm in the middle of building a 3406A as a personal project. I've got boxes of o-rings and gaskets that I am not 100% sure where they go now. Does CAT have some kind of online portal that customers can look up part numbers/locations?
