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
