BronsonA2150 Posted 9 hours ago Share Posted 9 hours ago Wanting to do overhead and set/check jakes on 94 Mack with e7. Are there marks or anything on the flywheel to spot the engine?

Joey Mack Posted 8 hours ago Share Posted 8 hours ago Yes there are.. but you need to run the rack the Mack way.. not the overlap way.. when you are up on #1, the #2 exhaust rocker will be rocked... It takes 2 full rotations to do the proper adjustment, once you get it up on #1.. P.S. do not loosen the rockers before starting.. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75845-procedure-for-setting-1-at-tdc-for-overhead-94-e7/#findComment-580564 Share on other sites More sharing options...
fjh Posted 7 hours ago Share Posted 7 hours ago Use the firing order valve set marks at on the flywheel thru the peek hole on the bottom of the engine housing! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75845-procedure-for-setting-1-at-tdc-for-overhead-94-e7/#findComment-580577 Share on other sites More sharing options...
