What would be the designation for a R model 6x6?

RMM

I'm only 29 so I wouldn't know. I'd guess the ESI + would be more popular on a highway tractor where you're logging a lot of miles, whereas local dump trucks and concrete mixers would have the ESI where your oil pan will sit higher from any off-roading threats. That'd be the biggest decision factor if it were me.

Here is my 79. Color is a dull red. Seems like mid to late 70s was when the red color was used on the engines.

That's an ESI+ not an ESI. 2 oil filters for ESI, 3 for ESI+. Different capacity oil pans. ESI + pan is 56 quarts of oil, 25,000 miles between oil changes.

Is your dimmer switch turned down?  Sorry I'm in an ask stupid questions mood! 😎

Dumb question: is your coolant level low?

There's probably a few temp choices when buying a thermostat. Cars are like that, you can choose 175°, 180, 185... No idea what choices Molvo gives you. If you're down south maybe the factory put in a cooler thermostat because you deal with hotter temps than we do up north. 180 is what I like my trucks to run at, but everything I have is '95 and older. My 95 RD pushes 200 a lot. Need to clean the radiator and intercooler.

Whilst Im not questioning how accurate the information is here at a quick glance at Mrs Mack I cant help but notice she only has normal grade 8 bolts at best on her chassis 

 

Grade 8 is right, but Mack frames are assembled at the factory with "body bound" fine thread bolts, which are an oversized bolt in an undersized hole. 

All suspension, crossmembers, steering, cab mounts, fuel tank brackets, etc etc should be body bound bolts. Air valves and relays etc can be whatever the heck you want.  I had an 01 Mack tractor that used "Huck" bolts for the air ride suspension. They're an approved alternative in some cases I assume.

I think it is a Mack color, I've got the same engine the same color on the shelf.

Note that I said gotta disassemble BEFORE it gets to cracking point.

3-5k per rail. So you're looking at 12-20k if it's a double frame, just in rails. Add in 1k in bolts, a few likely broken crossmembers, you're looking at 25k. If your rails are still good like ours were in the last one we did, why take on the extra expense?  Our truck only gets 5-10k miles a year, never in salt, so we're going to get a few decades out of our rails.

I prefer red as it's mine:

No hood scoop yet but it's coming.

 

You have the 56 qt oil pan that comes with the ESI+ package. 25,000 mile oil change interval. And an engine that'll run that long and then some between trips to the dealer.  Standard came with with 1 filter, small oil pan. ESI came with bigger oil pan and 2 filters, ESI+ got the 56 qt oil pan and 3 filters.

Wish I still had the intake plumbing to go with the hood scoop, but that went in the dumpster a long time ago....

😍 is that a real Mack? Or is that a custom??

Cat would be interesting, but I don't care for their engines. Others do, I don't. What made Mack legendary was their engine/trans/rears. They were engineered as a package. To make Mack what it was, you have to go back to that. Cat makes their own engines, I don't see them making their own transmissions and rears to stick in a "Mack". Im a Cummins guy, so I would like that, but Paccar sells a lot of Cummins, I don't think it'd be in Cummins best interest to compete with existing customers. I don't see Mack getting out from under Volvo's thumb. In a decade or two when my current fleet of Mack's starts to wear out I may have to start looking at other brands.... Heresy I know, but I don't know where Mack will be in 20 years, and we don't buy new, we buy 20 years old or older, and Volvo is already dropping etech stuff, so I don't see Volvo being a good support for my needs. I'll need a dealer with good support and that'll likely have a Cummins motor involved.

Thread is a good read, I was perplexed first time I saw a truck that didn't use 15w40 for steering fluid, but older Mack trucks are all I'd driven to that point. Gotta use what the manufacturer tells you to use, doesn't matter if you bought something else in bulk for other trucks.

KsCarbel2 lays out a pretty good argument, I'd agree. If Volvo wanted medium duty they'd just buy a medium duty company to to get into the market. I doubt they'd put any substantial effort into building the Mack brand. I assume they'd do it with their own name, unless they don't want bad PR for a shoddy roll-out.

That's what happens when you have a media in the tank for the democrat party they are very good at lying by omission of key facts CNN is a expert at it. 

 

Something like 85% of journalists are registered Democrats. That about sums it up! It's not news it's propeganda. The same that allowed Hitler and every other fascist rise to power.

Umm, perhaps you're looking at the reflection of the brake pedal, resulting from the camera flash. This AMT-equipped truck has no clutch pedal.

I was looking at the indent as mentioned by phase 1 and milkman.

It would appear that Paccar replaced the Clutch Pedal with a spatula holder for flipping pancakes while you drive. Or it's so you can buy a $0.50 spatula to mount there and pretend you're a real truck driver. 

Zoom in on the lack of a clutch, you'll see what I mean.

Everyone loves a Superliner.

That superliner has too much hood for a single axle.

Not sure, but I have been less than impressed with "rebuilt" air compressors from my dealer for my endt676 engine. I've replaced a couple because my wet tank loads up with a thick oily tar. Throwing rebuilt compressors at it won't make it stop filling with this tar so I gave up and just drain the tank every month or two, drawing as much as half a gallon or more of this crap out.

My 95 rd has the C channel bumper and the uprights, all in stainless. It looks sharp on that Hidden R. My 79 R has the same style bumper minus the chrome and uprights, plus a few scratches and dents.

What style spot mirror brackets are those on the hood? I'm putting together an '88 R triaxle and it'd be nice to have spot mirrors up front.

I had a 2001 etech 400 that would take longer than usual to start because the cam position sensor was bad. 

Did you grease the filter gasket before putting the new filter on?

When did Mack start using that bumper with the uprights? Never noticed it on the original style hood trucks. Only ever on the newer R hoods.
