I have picked up an 87 case trencher with only a front grader blade and rear D100XR backhoe. The backhoe is making a loud noise when only lowering the boom. The sound seems to be coming from a 2 port valve that is bolted to the cover on the swing gear. I have looked any many other pictures of this backhoe and have not seen one picture with this same valve. Attached is the picture and I hope someone on here will be able to tell me what it is, thank you.
