r686st Posted April 14, 2020 Share Posted April 14, 2020 I have a 2000 Mack Ch613 that I am replacing the engine in currently. It has a E7-460 Etech with 690B Jacobs Engine Brake and I need some information. Thanks for your help! Injector torque? Jake brake housing to rocker arms torque? Jake brake lash settings?

fjh Posted April 15, 2020 Share Posted April 15, 2020 Just A note to Tech's literature here !His last pic shows the actuator pin side view ! The little mushroom end had a a tendency to break from time to time you should always check these when setting the valves and jakes replace the screw if broken and good luck finding the broken bits! 😒 1 Quote Link to comment https://www.bigmacktrucks.com/topic/62053-torque-specs-and-lash-settings/#findComment-448826 Share on other sites More sharing options...
