Did he pass on or has he just not been on in over a year? Ive messaged him but have never got a response. Sucks I joined too late I never got to meet him

Im pretty sure the Air compressor is driven from the injection pump so it will have to be removed. I'd say if you take the governor off without the rest of the pump the rack might be Impossible to retime

Compression test and injector test. You can send them off to someone who knows what their doing but if your cheep and stubborn like I am I'd rig up a tester yourself. There are several articles about how to turn an old hydraulic pump jack into one or you can buy one off amazon for a reasonable price. When testing you're looking for 1. Spray pattern, I have a great video that explains what your looking for here: Next your looking for injector cracking pressures, its best to find a book describing what these pressures are but if you can't its more important that there within about a 5 to 10 pound difference between injectors (the less difference the better) Not too sure what brand of injector Mack uses but I would imagine its the same brand as the pump, there may still be kits available and you could rebuild them yourself if you have the proper specs and your wife doesn't mind the smell of diesel fuel in the clean house. Injectors might not be the problem but their old and its something to look into on older diesels, well balanced injectors make a world of difference.

Who's really the stupid ones here? We can make oil from natural gas and gasoline from coal. I mean its almost never stated how the Nazi's got there gasoline for there airplanes, the answer is coal! If we have enough to burn underneath a town for 70 years than there's no reason for us not to be refining into gasoline if crude oil is sooo hard to find.

I know someone on here was telling about an 80s Mack with an automatic, there rare for sure! I know that the UPS truck's had some weird transmission trickery but Im not sure if it was an automatic or not.

I guess its running good...

Im a big Cat guy so this is awesome! I have a couple of questions though: Could you get a Mack transmission with any engine or only with Mack engines? Also Ive never seen a Cat engine in an Ultraliner. Ive seen some cummins and a couple of Detroits but never a Cat, are they rare or did they just never put them in em?

More gears is typically better but here are some links to the ratio charts so you can compare: https://thompsonmachinery.com/content/uploads/2017/04/10speed-Eaton.pdf xhttps://www.eaton.com/content/dam/eaton/products/transmissions/vehicle-transmissions/8ll/eaton-fuller-on-off-highway-transmissions-brochure-trsl0116-en-us.pdf Id say you can't go wrong with a ten speed but they both look like they have about a 34% slope per gear.

One of the coolest sounding Diesel engines in my opinion!

Pictures can tell a thousand words but they hide about half of them. Full inspection would be necessary for that kind of money but at the same time why would anyone pay that much? recently a guy on here payed 10grand for one (I can't remember the poster) and if you dump another 20-30 into a resto you'd have pretty much the same thing. It just doesn't paper out in my head.

It's seems I have the opposite happen here, people use a gun to take the plug on and off, you can definitely tell who changes their own oil by who doesn't have wet spots on there driveway from a stripped out plug

Ok I really don't mean to beat a dead horse here but I found this thread here: https://www.bigmacktrucks.com/topic/28092-t2090/ specifically this part: I know it's probably up to the whoever's paying for the transmission rebuild but it still makes me wonder which pattern is better for the transmission in the long run. If the old pattern transmission and the new pattern transmission are mechanically and internally the same than I'd say shift it in the new pattern If it goes smoother, 4th low always sucked to get into anyways.

Weld and brace the frame back up and keep going, that's what my neighbor did and his pickup split in half. If its done right it'll be better than new.

I thought you couldn't order a real Mack truck since December 18th of 2000. Jokes aside no I haven't heard anything but maybe there some shortage that's causing it. I also heard somewhere that def was being phased out by 2024, anyone know anything about that?

Whats sucks is now that cash for clunkers ran its course a whole generation of cars is now gone and some models almost went extinct. Cheep 80s and 90s cars are not as common as they used to be. Its sad that I never got to experience some of these cars that are now gone from the roads

https://www.boekeandsons.com/Inventory/?/listing/for-sale/214992953/1985-mack-mh613-cabover-trucks-w-slash-sleeper-heavy-duty-trucks?accountcrmid=10904325&settingscrmid=10904325&dlr=1 I think it's a fair price if the truck looks as good as the pictures show, same sight has a 1980 Freightliner cabover with a Detroit for 20 grand more (who in there right mind would buy that). How did these ride with the taper leaf suspension? Is it hard to convert them to air ride?

Those newer carbs that Kohler uses are POS in my opinion. I couldn't ever get them to run very good but they are very cheep, $12 on amazon for a new one. I don't have very good luck with carbs anyways.

I tell ya if I got a hold of one of those new Volvo engines I'd take great pleasure blowing it to bits.

Is that picture in the Mack museum? I wonder how it escaped and why they didn't keep it and use it for an advertising campaign. Its just odd And I didn't realize that Mack had made so few trucks in 86 years, Henry ford build a million in 2 or 3 years

I wonder what "The One Millionth Mack" means

Does it have a Bendix? Ours always pukes oil into the tanks but we haven't had much problems with it building air

Yep the code talkers could never be broken. My mom taught her first years as a teacher down on the Navajo reservation in Arizona, she took classes from one of the original WW2 code talkers. But Navajo isn't taught to kids much down there anymore so it's likely the language will disappear soon.

I'd work for ya If I lived closer Joey. You learn to be a good grease monkey having to grease at least 100 grease zerks a day cutting in the summer and fall.

They're in just about the same boat as us with China taking all of their industry away and regulation taking the rest. After the bubble burst in the 1990s Japan has never really gone back to their former glory.

Looks like it doesn't have a Mack rear end, wonder what transmission it has. Can you tell by the vin?
