I don't think your picture is of a 7140, Mike, it looks to me like the old previous style, as it has levers, my 7140 had no levers.  If yours were the type with no levers, there would be a zerk in the place you cannot see in the picture, if I remember right.  I haven't even seen the connectors on a 7140 for over 6 years, but I sure remember them being on the connector.
