The Heinz

We had an older MR trash truck come in needing a DPF, and of course the OEM DPF was unavailable at the time. We put an aftermarket in after the customer approved, only for it to come back a few weeks later with the same issues as previous. Found out the filter media had broken apart from the DPF housing, and was causing issues by being able to move around. Hate that going OEM seems like the only option, lots of money in Volvo's pocket.

I have very little experience on their quality, but their parts are EXPENSIVE. And hard to look up. We're not an actual Autocar dealer, but I've had to order parts for them frequently and man, is that website frustrating! Really slow, I mean REALLY slow!

Reading his write-up, it sounds like his EGR fault was preventing a regen, which it will, with an aftermarket EGR valve. I'm not a tech, but I stopped finding aftermarket NOx sensors because they would always come back a week or so later, and I would bet EGR valves are the same way. I've only ever sold OEM EGR valves because no one in my networks even carries aftermarket valves.

It's a 1998 CH613. E7-427 VMAC II (mechanical injection pump w/ econovance) and Jacobs 680B engine brake, T2180 18spd Mack transmission, and Eaton S404 rears 4.11R. Has air ride rear suspension, and a section in Impact for a "NAMEPLATE, CUSTOM BUILD." Seems someone ordered it special?

Those are the cameras for the digital mirrors, because Mack was already known for having rock-solid electronics. Can't wait for a massive recall about it to come out, only for there to be no inventory. Happens every time.

Build date 3/1/2001. E7 460 ETECH LSR, did come with the 13spd Eaton factory, 3.70r Eaton S405P rears. I don't know any history other than that.

Even though Volvo owns Mack, Mack has a LOT more support for their older trucks than Volvo. Early 2000's Volvos are getting the axe already, don't ask me to get a power steering pump for one! I've been having a lot of success getting parts for these slightly older Mack's, and if the parts are unavailable, PAI usually has it. As much as I hate modern Mack, they are trying to keep the older ones alive it seems.

I had the same issue with my pickup, still having it actually. Previous owner put water in and I never knew until I checked recently. I pulled the lower radiator hose and flushed it using a garden hose until it was completely clear. Did the same with the heater core, which we knew would eventually clog being the highest point in the cooling system on my truck. It eventually plugged so solid that no heat at all would come out of the vents, so that ended in a heater core replacement. I plan to keep flushing like that every once and a while, because I know it's still nasty in there, but I've been afraid of running anything through it other than water. Think Cascade powder is good to use?

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!

eMedia Center in Dealer Portal is where that is normally found, but it looks like eMedia is down for maintenance at the moment. I'd keep checking throughout the day.

The Mack museum confirmed the truck has a Cl258 clutch, but I'm having the darndest time finding a number I can order for that. The M4106-15200VBS Steve gave was a good lead, but I can't cross it to anything I can get. Anyone have an idea about a Spicer number or something?
