7040 Piston Pump Seal/Gerotor Pump

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Good morning. Working on replacing the gerotor pump seal and pump drive shaft seal on a 7040. I'm seeing in the parts breakdown that some piston pumps have shaft seals, some don't. A preliminary look at my pump says it could have a seal, but currently doesn't. Should it? I'm also wondering about gerotor pump oring. I'm not talking about the 2 identical orings on the diameter of the gerotor pump, but the oring that sits on the face of the gerotor housing. Thank you
