So the VMAC II retrofit kit (215SB224) is available in Mack warehouses, and by that I mean they show to have a singular kit. It is really expensive.... The OEM supersession of your ECM is utterly unavailable from Mack or all dealers in North America. Unless you want to upgrade to VMAC II, I'd check out Vander Haag's or eBay. There's also a GoECM website I found online, you can either buy one with a lifetime warranty or send yours in to get rebuilt. I don't know how valid or reliable they are though.

Here you go, I managed to find it in eMedia. sb210032.pdf

You're right, I didn't see one in Impact. It may be the early morning brain fog, but do camelback suspensions usually have a transverse torque rod? I can't remember if they do or not.

Current Controlled Rate Shaping. I have a bulletin specifying more I can try to scan here. It will take me a while to do so, busy busy busy.

If you send me the VIN or last 6 of it, I can see what Impact shows your truck having installed. I don't think I've seen a truck without a torque rod, regardless of suspension setup. That might be a case worth taking to Mack, just don't expect them to care. We don't have the Mack that cared about their image anymore.

The WIF sensor could be going bad, especially if it was the bowl type primary filter and was cleaned with brake clean. I saw similar failures in KW T680's; I was new and was taught to clean the bowl with brake clean by the older guys in the shop, turns out that tends to kill the WIF sensor. Live and learn I guess. If it's the bowl type, I think the entire bowl will need to be replaced, I don't think the sensor is separate. You'd want others to tell you more, I can shotgun ideas at you but it would be little more than educated guesses.

I reverse image searched and saw the earliest it was posted was on Reddit in 2019. No info on where it was taken at all.

We have seen a couple reman injectors bad out of the box, but it's not a regular occurrence. I'd price it out to see which one comes out cheaper, just make sure you use a reputable rebuild shop. Our local shop was cheap enough that even after our system marked the price up, it was cheaper than the injector itself.

Sounds like the transmissions are different, as shown by "due to an extra gear in the transmission." These kinds of things tend to happen when critical jobs are rushed. Most of my PTO experience has been with Allison transmissions or REPTO styles, but you have to be very careful and precise when making sure the transmission and PTO are 100% identical. We had one truck come in with a "non-operable PTO" complaint, which was 100% accurate. However, the PTO installed on the truck was geared clockwise, when the intended setup was counter-clockwise. Someone who the customer wouldn't say had ordered the incorrect PTO to start with. Just some friendly advice: remember that rushing blindly into things with the intention to make the process faster most often leads to making the process take longer. I've learned that in the few years I've been in this business, and would recommend everyone follow the same belief. Slow and steady wins the race!

I'll see quite a few of these hauling to and from the feed mill in a nearby town. If you eat at the Cookout in town, you can see some neat old trucks coming by. Other than that specific place I've been, not too many are seen around here. If I'm not wrong, these Freightshakers had the option for Cummins, Cat, and Detroit from the factory, like the Paccar trucks.

Mackpro is right on it. Usually that issue is caused by a faulty controller. Replace the cabin air filter and inspect/replace the control switch, and you should be fine assuming the blower motor itself is fine.

I know my buddy's 7.3 I mentioned needs the glow plug relay replaced, it refuses to cold start below 55° and seems to start hard in the morning when above 55°. No engine light (bulb works), but I haven't been able to confirm by checking the relay itself yet. I'm 90% sure the relay is the cause, I clued in when I turned the key on back in the winter and noticed the Wait to Start light went out as quick as it does any other time. From my time with the same engine just under the T444E badge in church buses, I feel the controller would cycle the plugs longer than that.

I second FJH, the pins on the leaf spring fronts don't hold up very well at all, regardless of whether they were greased or not. If you've got drum brakes, you might have some trouble there; we've got one of our church buses doing similar with a loud clunk in the rear when stiff braking. The slacks don't adjust properly, and while I haven't had a chance to check, I'm willing to bet the s-cam bushings are wallowed out too.

I've done some work on my buddy's 1996 7.3, and have researched more myself because of it. Straight piping it won't hurt unless he dumps it way too close to the engine, and I have to say that even though his was straight piped when he bought it, the engine is still louder than the exhaust! What will drastically reduce the engine's lifespan is any "tune," over-injectors, or whatever else the dipstick does to make it roll coal. I despise these kids with mommy/daddy money ruining diesels to make it blow smoke, it's asinine and ruins good engines. If he wants to make it at least somewhat capable of modern road speeds and acceleration standards, he needs to have a GOOD intercooler installed. No injectors needed, I wouldn't put a bigger turbo on it, just the intercooler. My friend's friend (also an acquaintance of mine lol) has a similar OBS 7.3, and has only had an intercooler installed as a performance mod. Gets good power, better fuel mileage actually, and the engine just runs better having a cooled turbo. If/when your buddy ruins his 7.3, as long as the truck's in good shape, I'd buy it for $100 and slap a 12 valve in it. Or install a Cat 3126 in it like DEBOSS garage on YT did lol.

I don't want to go too far down the political rabbit hole, but I feel I need to say my piece real quick. If there's any conspiracy behind this, I wager that his political opponents could have manipulated and/or paid this individual to attempt this. However, given the absolute lack of skill and proper kit, I doubt this was a conspiracy. I've seen the aftermath pictures of this individual, and he absolutely appeared the type to think he had the ability to "do the world a favor" as he probably thought. He looked like he would have been bullied relentlessly (I've heard rumors he was) in school, as hateful as that sounds. If there's any conspiracy, it would be how inept Trump's security team was. I see the pictures of the lady cowering behind Trump and the other Secret Service; she should have never made it out of an office. Given the head of Secret Service appears to be a DEI pick, and previous attempts to take Trump's Secret Service protection away, I could see that being an under-table interaction. I also don't believe the sniper that ended the shooter was at fault, he seems to have noticed right before the shots were fired, and dialed his gun in and took the shot. If the reports are to be believed, he supposedly shot the kid in the head. Nice shot. Sorry if I come across as a bit hateful, but as someone not much older than the perp, the shooter threw all kindhearted feelings out the window when he took the shot that killed a husband as he protected his family. That piece of trash deserves all the bullet holes he received, and more.

I only have a 300HP and 460 HP VIN to compare, but the turbos are the same, nozzles different. GRANTED, the VINS I'm using are a 2000 and 2001 truck. The EUP's are identical as well. When it comes to lifters, what are the better ones to use, steel or ceramic? The latest and greatest supersession is ceramic tipped if that means anything.

Do you have an air leak on the transmission anywhere or in the bellhousing area? mDrive's are air operated, so if you have any kind of leak at all, it won't shift correctly. When's the last time you changed the air dryer cartridge? We see progressive failure all the time due to the air dryer not being serviced.

Anything made during and after Covid times has been exceptionally unreliable, it isn't just Volvo running things down, it's everywhere. Recalls have always been existed, but we're seeing a ton of warranty work everywhere. That being said, Chrysler never had a good reputation when it came to electrical systems, and I say that as a MOPAR fan. I've had sensors fail on my 2016 Ram 1500, so why would I trust my truck to tell me what my oil level was? Their spokespeople can say what they want, the main goal of removing the dipstick was to make people have it serviced at their dealerships. The 8HP70 transmission in my truck has been reliable for over 200k miles, but it is a sealed unit just like this new Hurricane engine, and is so much of a pain to service that it's best for me to have my transmission shop service it for me. This engine is also apparently really difficult to work on; I was told that replacing the thermostat was an absolute pain, and while I have no proof other than what I've heard online, I believe them. Looking up a picture of the engine, it's difficult to find any of the major parts I would look for while inspecting it at a car lot. I'll pass on this engine, not like I could afford anything newer than a 1996 Honda Civic at this point anyways.

I've gone down the old off-highway truck rabbit trail lately, and have fallen in love with Pacific trucks that ruled the woods of BC. I don't know if you have ever dealt with any Pacifics, but they have absolutely won my heart from watching the old film videos of those trucks hauling loads of logs taller than my house.

Yeah, Volvo hasn't been kind to Mack, neither has emissions requirements. Emissions hasn't been kind to anyone.

I've seen some UPS Anthems lately, but the UPS center in our area went away from them as fast as they could retire their fleet of CXU's. They were constantly having problem after problem, many ended up in our shop. I know a guy that works with them moving their equipment around, and he said they hated their Macks.

Impact had Big Cam II listed, I didn't know if that made a difference or not, my bad! Learning something new every day here.

I'm no expert, but I don't know if I'd recommend tuning and deleting an MP8. Believe me, I despise emissions even if I make a lot of money off of it, but deleting a semi truck that is liable to be pulled and inspected by DOT or God forbid EPA, you'd have rather kept the garbage. Also know it would void any warranty your truck would have, and dealers likely wouldn't touch the truck at all. Even if you're just trying to tune the engine for more power, understand the transmission is intended for a certain power rating, and going above that can lead to issues down the line. Ask the 6.7 Cummins tuners when they throw a tune on the engine and start adding power; it usually ends in a Billet transmission rebuild. There's probably more reasons not to mess with tuners on these trucks, but I wouldn't know as I am not a super experienced tech. Everything I mentioned is what I've observed and learned from talking with others about the topic.

1982 Mack R767ST, build date 3/3/1982. Cummins Big Cam 350, Eaton RT11609A. Original color may be white? Impact has a "CAB IN WHITE" listing, which is as much as I could find about paint. If you want more information, like previous owners and all, you might be able to call the Mack Museum with the VIN and get more than I can help with. An R700 with a Cummins and Eaton, sounds like a really cool combo in all honesty. As far as I'm aware, the Big Cam 350s were very good engines, but I know from experience they sound really good!

I'll try to look this up Monday once I get to work, online VIN search only shows it as a 1982 Mack R.
