If it has a DEF tank it has the stainless cups

Check turbo motor effort when hot. And do open and closed test on the turbo. Make sure they go to 0% to 100%. We have seen sticking turbo vains cause weird issuses
-
It should try to start a rolling regen at 100 to 106% . And same with a parked. Was the soot ratio reset at time of DPF filter replacement? Bad turbo could be causing soot build up. Mack usually wants us to remove pipe from turbo to DPF and do a "snap throttle" test to see if the engine smokes bad when reving it up. Remember , if your having high NOX problems, the truck will ask for parked regens to read the NOX levels to see if its clean enough to keep it from 5 MPH derate. If your soot ratio is not high and its asking for regen then its usually NOX related.

Your loosing J1939 com data line from engine ECM to vechicle ECM. It causing Idle to go to 900 rpm. Most common issue is coolant in the engine ECM. Unplug all 3 connectors on the engine ECM and check for rotted pins.

Unless its warranty we always use aftermarket radiators on the 2008 and up trucks. The GU's and the guys using the CHU and CXU for logging seem to go through radiators.

Any one heard anything on this? Heard it from the higher ups this morning.

Volvo/Mack Chicago training center
Mackpro replied to Mack Technician's topic in Engine and Transmission
I talked to some corporate people about the "See through valve cover" today. They were like "How do you know about that?" I did not divulge my source. LOL. Aparently the see through valvecover is coming in the next few months. Sadly today is the first time we have had a major issue with the new common rail engine . However it had nothing to do with fuel system. -
All warranty will pay for a road test is .3 HR.

We had lots of complaints on that year model engine but mostly the 427. Whole engine shakes at idle , but rev it up past 850 rpm and its fine and no low power complaints. Mack had a engine software update to help. Looking in my 'VMAC 3 software and data file part number" bulletin, it looks like they had a service file for " Misfire/white smoke" for your truck. Whats the model and last 6 of your VIN and I can check and see its its been installed.

I have maxxed out my download data amount. Is there a way I can delete some of the old pics and files in some of the old posts that I have attached years ago?

We pull the engine here as it's easier and faster. Usually $12,000 to 15,000 at worst. Depends if metal in oil pump, bearings and oil cooler. There's a lot more to it than just the gears. There is a 5 year 500,000 mile warranty on this repair
-
Yep. If you got the great big Borg Warner cool logic fan clutch, they are junk and are no longer made. They have a Behr fan clutch upgrade kit. The Borg Warner fan clutch is huge, its about half the diameter of the fan blade. We have little issue with the Behr fan clutch. Also, you truck could have the Horton air fan clutch on it. We see alot of the air solinoids go out on those but they set a fault code.
-
Can you read the number on the tag of the turbo? Should be like a 631GC5145M . If not , give me the number and I can pull it up and see if it's the correct one
-
I would say turbo actuator/vanes sticking , which should set a code. Or boost pressure sensor which won't set a code.

2013 Estonia fuller gear problems
Mackpro replied to Jim chanbers's topic in Engine and Transmission
There is a Fuller service bulletin on this on some models. Something about adding an extra spring. -
As mentioned earlier, they make a special lower o-ring for fuel in oil but nothing for the upper o-ring, http://hr.mckenzietank.com/maint/bulletins/42-sb221038.pdf

It was my buddy's CV with a 460

Trying to attach service bulletin

Could be the solinod pack/ magnet o-ring onthe EUP leaking. They make a o-ring kit for this.

That's good to know as I just bought a new Chamberlain garage door opener. I love their app on my phone . I'm 900 miles from home for a couple of weeks and can open and close from my phone and tell if it's open or closed or even how long it's been closed.

2008 MP 8 blowing black smoke, low power
Mackpro replied to br549's topic in Engine and Transmission
The failing turbo could have over sooted the DPF . Might be face plugged. -
We have had to weld a nut on the top of injectors befor and slide hammer them out when stuck in the cup. Mack has a really quick cup removal tool now, works great. On the cam issue, it was a injector roller bad and ate up cam. Thoses were 2010 Tyson MP8's and a few 2013's as well.

A few weeks ago I had a AI engine that was pushing coolant when hot. After trying several things I finally got truck hot and pulled the injectors real fast and then removed the radiator cap. I used a long rubber tipped blow gun and pressureized each cylinder till one started blowing bubbles in the surge tank. Pulled heads and checked head gaskets and liner height. Finally installed re-man Mack heads and all good
