nelsontrucking01 Posted February 24, 2018 Share Posted February 24, 2018 Does anyone happen to have a diagram for the 97 rb690s? I have called our mack dealer and they have informed me that their computers will not go back that far. Their computers only go back to 2000. This is an EM7---Mechanical engine and needing the diagram to figure somethings out with this truck. Thanks for the help in advance! Quote Link to comment Share on other sites More sharing options...
