The Burren

Bringing back some of the old dog's good humor...

The last post from Mack Technician 8-15-2020

"Pleased we're seeing a drop in COVID cases here since King Ever's mask mandate. Last week only 1 in 10 engine oil samples came back COV19 positive. The week before it was 4 positive tests, even though the machines aren't showing a single symptom."

I was trying to find the post that got him banned, just wondering what it was. All I found were jokes like these and repair instructions. This is the last one he wrote before he got banned. Check out who liked the post. 

Digging up bones I guess.

Thanks for the info.  What rears were in that ch?  I’m going to have to assume that a current 435HP motor with 4.10 will be able to do what I need without working too hard.  Nonetheless I am concerned a bit about fuel consumption on the highway.   What were the rears in the Pete?

I’m tossing around thee idea of adding a tri-axle and I’m stuck on the trans.

I live in Eastern SC which is called Low Country because its flat.  Sandy and flat.  This truck will probably be doing dirt and stone but it may end up (god forbid) as an asphalt truck.  

What are the pros and cons of the 8LL/ Allison?

I test drove the Allison and it was amazing off the line.  Will this change when loaded?  How about fuel mileage running highway speeds (70mph)?  The Allison has 425HP 4.30 rear and the 8LL is 435HP 4.10 rears.  My 05 Granite is 370hp with 4.64 rears and seeing 70+mph means you’re watching the fuel gauge drop in real time.

I’d like to avoid wasting money 

 Thanks

Yes, but it is a dump truck so I dont calculate fuel mileage.  On average I'm probably saving an 1/8 of a tank or better a day.  

I’m getting 6 driving like I stole it

The only thing a guy can add to that level of engine performance is disappointment!

I have a 2007 Cv713 with a Moffet and a Knuckle bloom attached and a 18 foot flat bed sometimes loaded with up to 20,000 in weight. How can I add some more power to my truck? I’ve seen the heavy duty Diesel tuner for $1700 but I see you guys talking about the 12B how do I update my software? Currently have 235,xxx miles on mine I work for a company who is willing to pay for the upgrades if it’s reasonable so I’m taking some time to look into this. 

I bought an 05 and put in an E7 exhaust, 5” GR pipes, injectors from K&S and a borg warner S467 with a billet wheel.

What color is your engine? Mach Tech can probably help you out for some beer.

What's the specs on the turbo you got? Looks like it will flow a ton better and keep egt's in check

 Mack Tech pointed me to this thread 

I ended up using his same turbo which I believe was a borg warner S467 with a billet wheel.

Its a little bigger than the s300 and definitely spools earlier and flows nicely.

Im no expert but the larger exhaust manifold and GR pipes in conjunction with the turbo and injectors from K&S have really made this truck a pleasure to drive

Lol, while you have it stripped for kingpins you better add an extra leaf to the front right spring to support that turbo, we don’t want to create a lean!!

Careful about running with no pyro, it’s your insurance policy against a blue turbo. 

Old Milwaukee.

Ha, Old Milwaukee.. no surprise there;)

I remember drinking many a Milwaukees Best...

A year supply headed your way!

10-4 on the pyro!

K&S injectors installed

YTS Turbo in

exhaust manifold on

New rocker shaft bolts

Dual 4” pipes replaced with 5” Grand Rock exhaust and M-132 muffler mounted 

Doing king pins tomorrow morning

Still need a pyro, but for now I’m just going to plug it up.

All in all coming along AWESOME!

Who’s thread is this again?

I’m sending you a beer.

Got it. Ill call the dealer Monday and try to get the new rocker arm bolts. Thanks!

WHAT? No broken studs? Those two old ones are going to start bothering you....better crank on em! 😉

Did you take Mackpro's cue on replacement of the rocker arm bolts? They have a history of snapping and killing the camshaft. Be easy to R&R one at a time.  

Wait a min.. where was that Cue on rocker arm bolts...

Forgot to take an actual picture of the pipes... but they looked perfect, and HUGE compared to the stock ones.

Here's the exhaust I got for 200.00

My 70 mile 1 way trip is going to be so much nicer now. 

Don't know where big John got that extra 5

Headed to pick up my pipes. I hope the numbers I used were correct

Ok, so ive been saving my nickles to do the 5 inch exhaust(my local truck pro can get them, has already quoted), exhaust manifold, K&S injectors and 400 turbo, but i just read something that concerns me, if my local dealer has the "Grey Motor Amnesia", does that mean that installing the parts wont help? Or just that it would run better if it had the dealer tune it after?

Just curious, if there was a way to convince the engine brain that the engine had boost, say 10 lbs or some low number like that, by fooling the boost sensor/manifold pressure sensor electronically, would that allow more fueling earlier? Maybe allow the actual boost to build quicker, minimizing the low end lag? Maybe a resistor or something in the circuit? Im not interested in rolling coal, just thinking aloud

Called 3 places today asking for quotes for the front and rear pipes:  

1. Carolina International Trucks, Florence SC

2. FleetPride, Wilmington NC

3. Truck Pro, Charleston SC

**Carolina International Trucks — called back within 15 mins best price by far 843-468-9560

Fleetpride out of Wilmington NC came back with a quote of 

$305.00 FRONT

$325.00 REAR. PLUS FREIGHT CHARGES 

TruckPro never called back

1. Gray engine amnesia is real and plaguing Mack dealerships across the USA. No guarantees your dealership has an experienced mechanic who will negotiate software changes well. Some guys have had to travel. Dealerships aren’t able to tie down the millennials and may not treat physically older mechanics as valuable. It’s case by case from what guys are expressing to me. When I was foreman in our shop I had a customer tell one of my older mechanics he should be greeting at Walmart. I’d love to have stuffed a fist in that guy’s pie hole, however the mechanic told him off before he said that...so? When folks are paying $120 an hour they want a young punk. Makes older, knowledgeable, guys under appreciated. 

 Talk to your dealership and make them liable via promise..... “Hey, if I buy this Mack and become a new customer what can you do for me? Can you change my horsepower and update software on Gray engines?”. If they say “yes”, ask to talk to the mechanic directly, verify it, and get that mechanics name. 

2. Fuel service places keep those injector upgrades private. They have to play around with tip swapping to find a new fit for each horsepower bracket. let them do it, don’t try it yourself, let them be liable so if it’s wrong the replacements are free. If you crack a tip out in the field and need a tip replacement Mike (K&S) will tell your vendor what tips to use. Your vendor will have access to the replacement tips directly from Bosch. Mike vends them cheap, good OEM quality.

 

10-4.

Hey Mack Technician— thank you for the quick response.

  Questions:

1.  When you wrote

“Can’t recommend these trucks for purchase except to say I’d buy one because I have my previous coworker at the dealership who can still drop files into them and provide all other internal support and I’m very familiar with them”

are you saying that the regular user (me) WON’T necessarily be able to get an updated flash file downloaded if my rig is running old software?  

2. I can’t find the post which lists the upgraded injector part numbers to buy.. Am I mis-remembering what I read?

Thanks for the recc. re. Josh Stewart.  I’ll give them a call Monday.  I’d love exact part numbers for the proper manifold turbo and injectors if you have them handy.  These parts (assuming they are a direct plug n play replacement) are something I would be able to install easily if it will make the truck that much better =

Thanks—

UPDATE— is the 631GC5153M4 SA400 WithOut wasteGate what I’m looking for for my AI400 motor?

Awesome information, thanks to all you experts for taking the time to share.  I’m getting ready to switch gears and buy my first dump truck. I took the advice of a buddy and decided on a low mileage 2004 CV713 with AI-400 12.0L MACK 400 HP and MAXITORQUE 9 SPDS trans. I’m going to be running mostly dirt sand and stone at ~70K in hot temps.  So my question is, should I avoid this engine?  I don’t mind spending some additional money and upgrading a manifold, injectors, and turbo, but the part numbers from Grand Rock don’t bring any results on their search page so I’m assuming that it was a one and done single run custom job?  The truck was a specialized oil field truck and has a new 17’ steel body, PTO and cylinder and looks clean in pictures. I’m flying out this Friday 9/27 to take a drive and check it out and if everything looks good I was going to hand the man a check and drive it home.  Any advice would be very welcome—

1. is this engine a dog without doing the conversions described in this thread?

2.  What exactly is the minimum I’d need to do to make it run properly?

The last 6 of the VIN 008206

The truck is listed here on MV Planet Trucks.

http://www.mvplanettrucks.com/admin/view2.php?ccode=156893884865881&startitem=&startpage=&endpage=&current=&category=&make=&model=&year=#

My cashiers check is in hand and I have a Friday flight, but for $60K if this engine is going to irritate me for the next 3 years I can hold off.  I have a little time to look for the right truck if this engine isn’t it..

As an aside, I could have gotten a 2016 Western Star for ~$80,000.00 locally.  It’s listed here but sold now.

Please someone tell me that even though its newer that this old 2004 Granite is still a better truck, otherwise I’m going to be kicking myself —

Thanks—
