Joey Mack Posted April 11, 2022 Share Posted April 11, 2022 the e-7 is a different set up. I believe the bolt hole are a different size, the jacobs 690 heads, have a larger hole and the bolts are shoulderd to fit in the hole, and they are metric thread, and the adjuster on the e-6 uses a fork to set jake lash based on turbo type, the e-7 uses a .015 feeler gauge, or .017, or .021 depending on the updates that were done to the jake heads,, and I think there is only 3 bolts holding the e-6 engine brake head down, where the e-7 uses 6...... I'm curious.... Jojo 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69518-e6-jakes/#findComment-494959 Share on other sites More sharing options...
