Bryce Inland Posted August 19 Share Posted August 19 I'm looking for some slave pistons to rebuild my jakes. I'm looking for 6 and can't seem to find them anywhere. I have an E7 engine... if that matters. Any help is appreciated!

The Heinz Posted August 19 Share Posted August 19 They are a 680B to be specific. According to the rebuild kit lookup on Cummins (new owner of Jacobs), 018678 would be the number for the whole rebuild kit, Mack's number being 4559-18678. In stock in Mack warehouses. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74481-slave-pistons-on-jake-brakes/#findComment-557300 Share on other sites More sharing options...
