Mack Technician

It's not you, Lou, it's the Truck. It's very fixable. 370 is a perfect candidate.

I'm a little suspicious of your friend blowing your doors off with his 2006 CV713 w/same set up? Does he go by the handle Old Red Mack, Nelm, Mackncheese, Big John, Dcrow,  03 Big Red, Mackvette, Mudman, Byrohoe or R.E.D.? If yes, then he's keeping secrets so he can laugh at you when he flies past you coming out of the pit.

Start a free range rabbit farm with those. During winter my New Zealand’s would eat as many dry maple leaves as you put in front of them.

I’m having the same problem.After the starter motor was replaced,the engine just cranks and will not start.Fuses good.Power and ground to VECU and EECU good.Any help would be appreciated.Thanks.

Go back in the chassis, dig around and find the power leads or ground run you did not attach to the starter post. Not everyone is getting fed.

The engine stop running on slow so I have to change the unit pumps. After changing I notice the engine will cut gas after a while when running on slow so I checked for oil gauge and I notice oil mixing with diesel. So I drained and I notice while I use the hand pump diesel drops through the oil drain tap. I changed the unit pumps kits. (The seal) but it won't stop.

I'd pull the fuel transfer pump and leave the lines attached to it. Pump it, free hanging, and observe the seal of the drive gear shaft isn't leaking into the engine. The three spots this engine can leak fuel into the oil is....

1. transfer pump input seal

2. Unit pump lower seal

3. gallery plug for the factory drilling. They drill two galleries through the entire length of the block. On each end of the drilling is a plug, so 4 plugs total. The plug hidden under the timing cover could potentially leak, but that is not usually the case. 

If you did a good job installing the EUP's, and new seals, that narrows it down considerably. Personally, since the pan is empty, and it's easy to do, pull the pan off, lay under it, and have your wife pump the primer while you watch the show from a strategic position. Then you'll know exactly what's going on. Good Luck!...let us know what you find.

2 Pac? Watch out, they might get shot.

Team drivers = 2 pack.....coincidence? 

Yup, and if you listen 10 minutes more you’ll be certain a roller is flat-spotting and you need a camshaft replacement. 

Did you drain the gas out of the gallery that runs between EUPs before you pulled them out? You can get a shot of dilution if you don’t drain it, maybe enough to show up on your oil sample. 

Unless it was a temporary installation, like a seasonal push axle removed during frost-break road limits, it was expected everything was Huck fastened and no reused bolts.

Stared at that pic for a while then recalled the 80's icon they stole that design from.....

MOXIE Addict I bet 

Just cause you cut the can open and lick the brown dried soda out of the bottom doesn’t mean your an addict. Right? I mean everybody does that? 

Speaking of making new addicts..... somewhere in the Midwest the feds (USPS) are bringing a shipment to Maine. Twigs Farmer’s Brewery butterscotch root beer. 

I don’t disagree with necessity. You can eventually get sick and tired of a lifetime parole for which you get no credit for good behavior, like with Dave. 

One time I went in and there was this old fella doing the tests. He looked like he was in great shape for his age, solid built and about retirement age. Talked to him for a while and realized he was one of those disciplined life military guys. Real frank about things, straight talk, no B.S. I asked him “you do this pretty regular, how many do you get?”. He said “I never know with the urine tests, but I had a guy come in a few weeks back, early morning, not a urine test, he pulled the random breathalyzer. He blew positive, a real low number. I said to the guy blowing “what you been drinking, this is suppose to read zero?” He told me “Super Bowl Sunday and his team won”. I threw out the test and zero’ed one for him. You can’t expect this guy to pass clean the morning after a Super Bowl!!”.

VMAC III isn’t even that old.  I can understand dealers not having anyone with VMAC I and II, and older Volvo experience.  But VMAC III? That’s sad.

Nothing like going to a dealer and having some apprentice tech with maybe a year experience telling you what you need. 

These are the guys putting engine harness on gray engines like they’re MP engines. 

“You need a set of injectors and an engine harness.”    Today’s Mack dealer

 

 

It’s a condition physicians are referring to as Rapid Onset Gray Engine Amnesia.

We used the cam from our spare engine last year for that exact thing. Carbide face cracks, wipes the lobe right off the camshaft. Mack doesn't make the endt676 cam any more.

Any time an engine does a hiccup I generally pull valve covers and oil pan. Valve covers will show you if you're having top end issues, oil pan shows you everything else, plus the pieces that may have dropped down.

FYI- if you ever get in an availability “pickle” Berry Cam Service out of Minnesota would likely fix that camshaft core. I had him build a cam for my rod decade back. He is tooled for Mack right up till E-Tech I believe. 

Spent 3 days this week in a training course with our company’s hydraulics trainer. He drops in from Oregon once a year. We’re going over Marijuana/alcohol regulations being enforced back home and abroad. He says no major fall-out from the pot legalization except kids eating THC candy. Anything we can’t figure out we googled, like why can a CDL driver’s BAC (in a personal vehicle) not exceed .04 when the standard is .08, etc. When it came to CDL and THC there wasn’t a lot of solid, available, info on how they are going to handle testing since it lingers in your circulatory system. Is there chatter in the fleets? Are they treating it as “federal DOT” so zero tolerance across the board, period? 

Use 3M weather strip adhesive on the steel stamp covers to keep the gasket from squirting out. Glue it, let it set up for a spell before installing covers, no comebacks with that stuff.

Cast... don’t  use any sealant. If the cast has a cut relief (in ribbon land) make sure there is no oil and completely dry during installation. 

Youch!....get a tar bucket maw, we’re reseal’in the driveway! 

Soak it with brake clean a few rounds, air bath, spray it with WD40, soak, and brass hammer(piston close to TDC).

Pulling the manifold will show a wet hole. Make sure you run it cold for two minutes before pulling the manifold.

Typically......check the timing to make sure you didn’t have a gear slip then buy new tips for all the injectors. Assuming you got a good service life from your injectors, they are essentially spark plugs...when it comes time for one to be replaced the others are usually not far behind. 

If your cold region consider Fred’s warning about bent tubes. It was popular on those to bend tubes, especially if you had a bad injector applying diesel-pus-super-glue to the valve stem. After a cold night sitting that crud glued the stems solid and bent the tube at start-up. Did a bunch of them from the same issue even with good injectors but driver idled too long, cool, before shutting off for cold night storage.

Requires brains, stupidity and a good prayer life?

Ever get the feeling you being watched.....

Not practical up here, even with available grants and enough groundwater to do a well exchange. I calc’ed it on my 1,700 house when we built in 2010 and the payback was past my life expectancy. Not to mention I’d still have to subsidize the system for two months. 

Wood boiler is nice with the “fix my Mack for firewood” barder program.

What does pln stand for?

P= pump 

L= line

N=nozzle

used to represent all the pre (to mid year) 1998 that had a jerk pump fuel system. E-tech was legally a PLN, but not a Jerk system and so no one ever referred to it as PLN.

Wonder if you had to dump waste oil on the ground to get around a tight turn?
