Wow what a looker! Did they put in vinyl floors? I don't think Ive ever seen something like that before.

Old thread but this thing is way to cool. I came across a video about it and let me down a rabbit hole of trains and fire engines. Don't know if it was stated before but the company that made the pump Deaval also made cream separators. Our family retired our Delaval and put it in the museum, now we just wait overnight and let the cream separate by itself.

Points and or a bad fuel pump can do that too. Nice to get it all back together!

I don't think they ever sold Moline's in Australia but I know Olivers and before that Hart Parr's were very popular down there. My great great grandpa sold Hart Parr's and we still got some advertising they sent him. One ad told of a Hart Parr they ran down in Australia for 9 days and 8 nights to break a world plowing record back in the 1920s. Tough machines

There Is a road boss a couple of blocks from me. I see it run a couple of times a year but it doesn't interest me very much, White killed Oliver and Moline back in the 80s and as a big Ag guy I still hate them for it.

Good to know! Had an Mh that surged and bucked horribly when it wasn't under load, maybe the governor just needed to be rebuilt

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

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
