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!!

also should i do bushings, rings, liners rod and main bearings? idk i dont want to go broke but i want it right. Besides a visually inspection what else should i look at or check? or use plasticgauge? also i did a cam and bushings about 10 years ago and my buddy worked at mack in the next town and he let me use there pulling tool i remember #6 being a pain. But my friends gone where can i get that tool? Any help i sure do appreciate

do i have to remove head to replace pin? i cant find any info on pins in the mack book i have

Can i replace the pin? should i turn the engine around and examine cam shaft?

no pin so im i sol whats the right way to go in this

oh ok that seems to make more sense duh thanks

sorry it took so long been covered up, so i blew air in the injector hole the only place i heard air was coming out of return line at fuel tank. But the eup roller has several flat spots should i be concerned or drop a new roller in and see how she does?

Mackpro can i put the air into the injector hole ?

ok thanks did not check roller will do that also no smoke, just bought about a month ago and it drove it 400 miles like that i will also do the air test and report back

im not getting a code put new 6 injectors and 6 reman eup pumps in a 2000 mr688s 350hp. i still have a miss did cut out test #6 is not changing. is there a mechanically test to perform to eup to see if thats it or the injector? Thanks for any help!!

Thanks, Steeler that did that job!!!!😅

I forgot to ask is this the one on the engine or inside truck?

ok Thanks i will give it a try

ok thanks did you run a new wire straight from ecu if so i could use the pin# for the ground if you have it Thanks Again!!

I have 2006 Mack mr688s (032711) with blink code 4-2, im assuming it has something to do with fan clutch because its staying engaged. I just put a new clutch on about a month ago, anybody have a schematic or advise? Thanks!!

no it was dry and clean

any ideas what might of caused this

well i found the problem burnt ecu and harness

also MackPro do they make def delete kits for this truck?

Mackpro would you have a diagram to that kick panel fuses to identify them

thanks, i check that cable and fuse all good. i pull engine hours it does not read just two dashes any idea where to go next or is this going to be dealer only problem
