Mack Technician Posted April 17, 2018 Share Posted April 17, 2018 (edited) Get the final revision manual and buy the proper tools. In chassis or out? what HP? What mileage? What failure?

nice b Posted April 18, 2018 Author Share Posted April 18, 2018 Will be doing an inframe, 427, not sure on the miles yet, lots of blowby and oil consumption Quote Link to comment https://www.bigmacktrucks.com/topic/53133-2003-etec/#findComment-396991 Share on other sites More sharing options...
Mack Technician Posted April 18, 2018 Share Posted April 18, 2018 Cake walk. Mack Publishes a great manual and the etech is nice to work on. Sometimes you have to pull the compressor oil pan(plate) to get torque wrench on buttress bolt.

turckster Posted April 19, 2018 Share Posted April 19, 2018 Just a pointer when replacing mains. #2,3,5&6 share the same uppers and lowers. #4&7 share the same lowers but have different uppers--can't mix them because of tang location. #1 has the same lowers as 2,3,5&6 but a different upper. I have seen people put the wrong upper shell in #1. The wrong one will fit in #1 but you will loose all thrust plus the oil feed is in a different location on #1.
