The Heinz

The bulldog likely hadn't been installed yet, the truck looks like it was delivered incomplete considering there's tape over 1/4 of the truck's body. Although they probably did delete it to make it .0000001% more aerodynamic.

Looks identical to me. Is this the NEW STANDARD that Mack says is coming soon? Something wicked is on its way for sure, and not the cool wicked.

You're welcome Vlad, I never mind helping out when I can.

Old number 14QK382P2, new number 24434811.

According to a 1991 RW7 VIN I have, old number 227QS310BM, new number 7843-1S6026. See picture below for what I see.

The 2017+ engines are so picky about fuel filters that there still isn't a good aftermarket for them. Donaldson seems to be the only one they'll take, anything else and you'll have fuel pressure faults galore. I don't even sell the Donaldson ones anymore, they end up more expensive than the OEM, and they're in a location that's harder for me to reach than the OEM. No brainer.

The mDrive is a problematic setup in general. Brand new trucks have come in with burnt clutches, and like 67RModel said, they don't seem to hold up to the abuse a dump truck sees. The few dumps I've seen with mDrives ended up having a lot of transmission issues throughout their life. They're extremely fickle with their air supply, so you HAVE to be on top of your air dryer maintenance and draining tanks. If hardly ANY water gets into that control housing, you stand a high chance of paying for a brand new transmission with control housing. I can't recommend those transmissions to anyone who isn't a massive fleet with near-endless money. I'm not too impressed with the engines either. The pre-common rail engines weren't too bad, but we've seen a lot of injector failures with the new common rail engines, along with camshafts deleting their own lobes. Hope no one needs one of those camshafts, because they're now made out of unobtanium; more than 200 VOR orders ahead of ours! Nobody makes a good product anymore.

I searched my old emails and found a case where someone ordering a new truck wanted to up the HP after it left the factory. Our foreman had this to say, and he wasn't trying to turn away the work: "As emissions standards get tighter and tighter our ability to do HP increases is limited. It is decided on a case by case basis. I’ll let you know what happens next week. If they do allow an increase it is usually a charge of between $2000-$3000 for a software change."

Tuners on these trucks are not very reliable at all, so I wouldn't advise you to go that route. I don't know if the cams/injectors are different between the ratings, but I do know the "right" way to accomplish an uprate would be expensive (and maybe impossible) to accomplish through Mack's channels. I'm think I remember seeing a notice that Mack would no longer send out uprate updates for whatever reason. Maybe others will have better information than me, all I have to go off of is what the dealerships will regurgitate.

Where exactly in Mack's systems would I find books? I want to look into the books that make looking up old Macks easier, I've had so many old Mack's over my counter recently that I know I'd make good use out of it.

I checked to see if Mack even made the bumper, which they don't, but also couldn't find any direct cross aftermarkets either.

I haven't heard of a system causing that much trouble, that's rough.

Truck came with an E7 350, it's mechanical except for the Econovance governor, Joey can tell you more if you need. Truck also came with the T2050 like you believe.

Did you replace the PM sensor already? I'm not sure if that's your problem, or how to actually diagnose it. I know that they usually throw a code when they fail. Part number for that should be 24307015 if you want to research it.

That will work perfect, they're the company Mack sends injection pumps and such to for reman, I don't see why they wouldn't be a good choice. I'll let me guy know, thanks for all the info ya'll! These trucks are very much so out of my league!
