The Heinz

I've never delved too deep into the ESV, so this might be a struggle...

Can anyone help me find a chasis wiring diagram for a 2005 granit Mack cv713?any help would be much appreciated!

What section are you looking at? These are my options per a 2004 VIN I have saved:

Depending on the chemical property's of your water, be sure to use some additive or a filter with additives. This will help both your water pump and cylinder liners..

Seconding this, we only use red 50/50 extended life in our shop, that's what Mack/Volvo specs with these trucks. 

We've had a couple ETECH's with weak injector seals that let fuel mix with oil, if I remember correctly. Been a while since that happened. The only internal leaks we've seen were coolant and oil from a cracked liner. I'm struggling to imagine a cracked block on an ETECH mixing fuel and oil... 

You say you checked, but I just want to say in case this helps someone else or might be your problem, but the most constant boost leak on the MP engines is the blue boots on the hot CAC pipe, the turbo-CAC pipe. Things go bad all the time. 

That tube with the two sensors is called the EGR Mass Flow Tube/Assembly, using those terms with a parts person SHOULD get you the right part the first time. 

If it's an mDrive, and it hasn't had transmission work done previously, it likely will soon. I wish I could be more positive about them, but we see a lot of failures even on brand new trucks with little miles, and I don't want to see anyone, especially a BMT member, get the short end of the stick. If this is the kind of truck you looking into, just be ready for that downtime and cost. If you notice an air leak in the bellhousing area, get that thing into an equipped shop ASAP, or you will have an even bigger bill than before. 

 PRO TIP for any DIYers or anyone with one of these trucks, there's a little metal clip that holds the air line going from the solenoid to the clutch cylinder. We have found that replacing that clip and putting a couple of zip ties on the hose keeps the truck from being as much of a repeat customer. Number 7 down below, part number 1521975. 

The fleet I worked for previously had Anthems around those years that weren't too bad when it comes to the engines. Aftertreatment and mDrives gave us problems, but they were getting close to (if not over) 800k miles before the company sold them off. We had the usual upper timing cover oil leaks and many of those ePRV deletes, but not too many engine problems in all honesty. We had a couple of cam issues, but with how big the fleet was, they were outliers. We had more issues out of the X15's in T680's in all honesty. I would trust some of these other guys' opinions though, that was in the past, and I'm a parts guy at a Mack dealership, where a lot of our work is the worst possible failures. 

I can't confirm this, but using a VIN I have for a '94 CH613 with an E7 gives me condenser number 25084242, which Mack has inventory of. For the AC lines, we end up getting a local hose shop to make them for us. The line from compressor-condenser is 25087831, receiver/drier-condenser 25092566, both of which are available. Can't confirm these fit without your VIN though. 

That or the oil pickup, glad he was able to get it fixed though. 

It's. So. Ugly. With how smushed the nose is, any kind of engine work will require disassembling the cab and dog box just to start. My techs already hate working on VNR's for the same reason. 

Can you post/send me the VIN for that Freedom edition? I'd love to see if frame rails were available from Mack still for giggles at least lol. 

I was just up your way yesterday, I came back from a trip to Knoxville through the Gorge just so I could go back through the area after Helene. Wanted to do that ever since Helene destroyed everything and halted my last vacation... Saw plenty of old Macks out there, a DM800, beautiful white R model in Clinton, TN, several 90's RD's, and even a Superliner still in service pulling machinery to rebuild I40.

Interested in the "starting capacitor". Is it like Maxwells ESM, where all the cranking current comes from the supercapacitor and the rest of the trucks electrical is separate?  

I ran the Maxwell on one truck for many years and loved it. Still have it as the guy who bought the truck didn't care or know what it was.

That essentially makes the trucks batteries all deep cycle service, where no high current loads are placed on them. 

With the Maxwell, as long as the truck batteries were over 10 volt and could supply around 18 amps at that voltage, it would charge and the truck would crank.  10volts is likely way too low for these newer "electronic" engine systems, but would start an older diesel just fine with batteries that low. 

Maxwell came in 2 voltages 12 and 24, but either could be charged off a 12 volt system. 

Then Elon Musk bought the company an suddenly the Maxwell was not long offered for sale! 

I'm not sure, I haven't seen one of the up close and haven't had much of a chance to poke around a lookup to tell. 

I hate to hear the Pinnacle will be leaving, it's the best looking truck in Mack's current lineup in my opinion, but I understand why. The Pinnacle isn't as popular as the Granite or Anthem, at least in my area. I see several, and they're not rare, but I wondered if they were selling well enough for Mack to keep them.

Do they have the 24 volt system like the volvo for faster starting and shifting?

Yep, they're a 24 volt truck.

Heinz- You say there is not an 11 liter (D-11) anymore for the Volvo. This may mean they are dumping the MP-7 altogether. Since Volvos are basicly highway throw away trucks the D-11 may be able to be dropped before the MP-7. There are a lot of MP-7's in Granites and trash trucks that may need support for a longer period.

I don't know for sure, I got this from an internal email chain. I wouldn't put it past them to discontinue the MP7 if it's not able to keep up with emissions. Emissions and fuel economy (arguably part of emissions according to some) are what drives the truck market now. 

Hino is a weird one to me. Parts of them are reliable, but their emissions system absolutely isn't. The scandal at least benefits the owners, because just about all of the bad egg parts on their truck are covered under warranty programs. From what I know, the pre-emissions Hinos are solid, and I believe it. Even the post-scandal trucks are pretty decent, considering they went with Cummins B6.7's as the powerplant.

J Neiweem,  We were told that an updated CHU (now a PI) was under consideration.    I have no other info.  

Next,  we were told that they will be offering more Cummins choices.  This is sort of related to the MP7 having issues meeting the 2025 emissions.  Although,  I think it may be the high HP versions of the MP7 (395 & 415 hp).    With the Cummins, comes the option of the Eaton "Endurant" Automated Manual Trans.   I've driven them but they hesitate between shifts more noticeably than the Mack m-Drive.  

Those Endurant transmissions are interesting at the least... At the moment, the only parts lookup I have access to is a PDF I found online, they aren't in InfoRanger or anything. They don't seem to be very reliable either, we see a lot of issues with the MTM that ends up in it being replaced.

So,  I just retired from the Quality Group at the Mack Macungie plant.  Part of the groups function is reviewing new projects.  So, that said,  I first worked on the new Pioneer and the improved Anthem in Oct of 2023.  They needed completed truck cabs to send for the NHTSB crash testing.   The last one was a few days before I retired on January 10th 2025.  I know exactly what the new Anthem looks like, but ..... sorry,  I signed non-disclosure papers on the project.   I can say it rides real nice.  And,  both the Pioneer and the refreshed Anthem get an advertised 11% better fuel mileage (relative to how much lead is in your foot).   If you are still driving for a living,  get your annual fuel bill out and figure out what 11% is.

Are the Mack Pioneer and the Volvo VNL the same? Only sort of.   The Mack maintained the dash layout that is more setup for the working man (switches closer to reach), and slightly nicer trim levels.  It also maintains the engine programing that gives the truck better throttle response, leaving MPG up to the driver (there is times you need power like getting on a busy interstate).    They share many many body and frame parts, which can help save costs and keep the company competitive.    As for the new look, well I didn't like the look of the original Anthem when it came out, but it grew on me.  Same with the new trucks.

What I know about the Granite Axle back and both axle forward models (Pinnacle & Granite),  They are marked for updates but I don't have dates.   The update are part of the latest emission standards which has fuel mileage requirements.   As for the axle forwards, I was told Volvo does not offer an Axle forward so they don't fully understand why people want them.   Maybe they should watch the training videos Mack has on the different axle configurations and the why of them.  A rather boring video but good info.

The last Anthem sleeper rolled off the assembly line a week of two ago.  The last Old style Anthem day cab will roll off later this year.

 

Can you tell me what you think of the new improved mDrive and clutch? The information we were given stated the control housing on the transmission had been upgraded and the passthrough harness weak link eliminated, so we're all wondering if it actually would be better. 

I don't know anyone that has the ability to do that, or at least one that wouldn't overcharge the snot out of your wallet, in NC. There's a diesel shop in Knoxville, TN that might be able to help you if you're willing to go that route. They're called City Diesel, and I've been told very good things about them and what they're able to do. 

It also just occurred to me that you'll want to swap flywheels and pilot bearings, but I think you already knew that anyways. Early morning fog, just wanted to make sure you don't do extra work because of me! The pilot bearing for the Eaton Autoshift is 20512915. 

If I had the VIN's I can cross them no problem. Just had the same issue with a customer's truck that had rolled over a while back, so they installed an engine and cab from a different truck, leading to us ordering the wrong flywheel for the engine, and then the correct one was wrong for the Allison in the chassis, because the engine was specced with a Maxitorque! We had to chop the ears off the Allison to fit it, voiding warranty with customer's approval of course (they did the same when piecing this Frankenmess together).

where is the Heinz when you need him! ?? 😅

I'm here, usually. Lurking in the shadows...

The part number for the valve off a '98 T2180 is 25501019, Mack has them in stock.
