  3. ok i have a 2006 mack mr688s (032711) with a concrete boom sitting on it. The truck would act like it was shut off but never cut out, the code is coming from vecu. It was happening once a month then once a week now 2X daily i checked from the batteries to power relays and everything in between and cannot find anything, the starter, alternator, engine grounds, frame grounds, the ground relay on drivers side by air filter behind little black cover its very annoying especially while pumping concrete any other trouble shooting advice would me great thanks!!!

  6. Ok so i have a 2006 mack mr688s vin# 032711 always would pop air out of purge valve every 10-15 seconds all day Air compressor went out so installed reman from mack as well as a new air dryer, governor, and new air line from compressor to dryer still popping off every 10-15 seconds could someone help a brother out on this? i have never had one do this thanks in advance!!!
  7. ok finally was able to press pin out with a mini 2 ton bottle jack, the new pin i was able to push right in almost by hand is that normal? I put some retaining lock tite on it just was wondering? i used a mini 8oz hammer to tap it flush with engine block
  8. Thanks for all the help ended up putting new cam and rollers in working on #6 eup tappet bore pin part# 20706385 are these just pressed in? having a hard time trying to get it to tap out, does anybody know of a certain way to remove pins? Thanks!!
  9. i would not call myself a shade tree guy, i have done 3 inframe's on etec motors that i still own that have over 10000 hours on since they were done. I was just hoping to get a few second opinions from somebody who might work on them daily. I have tools and yes i know about the magnets like i said in previous post i have replaced a cam! The bushings do fail, i was able to get some specs on them from another mack dealer. the gear on cam can get pressed off and on thats not a problem. i was mostly wondering if any one has seen this same problem and just replace roller? The cam just has a few surface scratches, i know that will shorten the life of it. Just was wanting to see if anyone had an issue like this and will it hold up another year or so on just replacing the roller and pin! thanks for the help!!
