Popular Post Mackpro Posted January 16, 2023 Popular Post Share Posted January 16, 2023 Mack updated the torque specs for the rocker arm shaft a while back. Some of the older books might have have the old data in them . This is only for the rocker arm shaft on the MP8. Tighten all hold down bolts to 44 ft pounds. Then one at a time, loosen and retighten to 30 foot pounds except the large single bolt in the rear , it stays at 44 for now. Then tighten all 120 degrees ( including big single bolt ) . This is 2 flats on the bolt head . 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70506-problem-starting/page/3/#findComment-521456 Share on other sites More sharing options...

Last September I did 9 sets of injectors/cups in a little more than 2 weeks so that’s burned into my brain. Plus all the years at the dealership where i amassed two 5 gallon buckets of just copper cups when we were doing the change over to stainless cups., never bothered to save the stainless ones . 2 Quote Link to comment https://www.bigmacktrucks.com/topic/70506-problem-starting/page/3/#findComment-521725 Share on other sites More sharing options...

Keep up the good work !

I started when the E7 had just been introduced. The old guys were bitching because they had finally gotten used to the E6 4 valve head engines. Had a really good old guy teach me lots . He was from Long Island and he used to restore Duesenburg cars when he was younger. I remember him rattling off torque specs of those engines. I wish I’d have listened to him more but I was just a 18 year older kid back then . I miss him greatly. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/70506-problem-starting/page/3/#findComment-521798 Share on other sites More sharing options...

Same thing with the injectors . I believe they upped the torque 3-4 pounds 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70506-problem-starting/page/3/#findComment-521818 Share on other sites More sharing options...
