fjh Posted November 9, 2012 Share Posted November 9, 2012 I'd like to know the answer to this one too!RonYup no air no stop! Makes about as much sence as having an air starter but they are out there. But In some apllications where a remote stop is needed this would be an asset . Quote Link to comment Share on other sites More sharing options...
GearheadGrrrl Posted November 9, 2012 Share Posted November 9, 2012 Might be Mack's old air actuated road speed governor from the 1970s and 80s? Quote Link to comment Share on other sites More sharing options...
mackcl96 Posted November 11, 2012 Share Posted November 11, 2012 that RW that you are looking at,, should have the old red cable shut down... I see that the leaver has the ear for the cable,,this truck mostlikly has a kysor alarm systemIn the 90's mack used the air shut down solenoid in the V8s but still had the red pull cable that now will read (secondary engine stop) Quote Thanks for hearing me out.You can have the soap box now---------JIM Link to comment Share on other sites More sharing options...
farmer52 Posted November 11, 2012 Share Posted November 11, 2012 Some older Macks I see have an EMERGENCY shutdown knob in addition to the ENGINE SHUTDOWN. What does it do? Quote Ken PRR Country and Charter member of the "Mack Pack" Link to comment Share on other sites More sharing options...
smorse54 Posted November 13, 2012 Share Posted November 13, 2012 The emergency shutdown cable attaches to this valve that screws into the fuel inlet at injection pump. Quote Link to comment Share on other sites More sharing options...
