    Mamdani is projected to win the Mayor's race in N.Y.C.  What i dont understand is, as an antisemite, how can he win N.Y.C.? Is there something wrong within the Jewish community in N.Y. C.? I saw footage of a Pro Palestinian rally in the streets of N.Y.C.

    The Jewish population of NYC is reported to be approximately 1.25 million. The Muslim community is reported to be about 900,000. So roughly only 300,000 "Jewish votes" "matter". The other 7,300,000 people in NYC probably don't care about a land border dispute 5,500 miles away as it pertains to who their city mayor is. My guess is they are probably more concerned about social, political, and economic issues within NYC and align more so with Mamdani on those things than any other candidate.

    an·ti-Sem·ite
    /ˌan(t)ēˈseˌmīt,ˌanˌtīˈseˌmīt/
    noun
    noun: antisemite
    1. a person who is hostile to or prejudiced against Jewish people.

    OPINION: I haven't been watching Mumdani's every word and action. With that said I haven't seen or heard of him being hostile or prejudiced toward Jewish people. I don't think being pro Palestinian automatically makes one an antisemite. I think it is possible to be critical of the Israeli government and not be an antisemite. Mumdani said yesterday:

    “Two years ago today, Hamas carried out a horrific war crime, killing more than 1,100 Israelis and kidnapping 250 more. I mourn these lives and pray for the safe return of every hostage still held and for every family whose lives were torn apart by these atrocities”

    Haven’t seen many out where I am in the Massachusetts and Rhode Island area.

    What have you been looking at? 😁. Your in New England. Just about any vocational Mack older than 2007 (maybe newer) will have those axles under it. There has to be a litany of of those trucks still running around up there. You asking about an axle and carrier design with at least an 80 year legacy and have been essentially unchanged over that timeframe. Of course there are pros and cons when comparing them to other axles, however, generally speaking they are probably some of the most robust axles available without getting into specialty stuff. Of course this is a Mack forum so the information may be biased but I have never known anyone to dislike that setup for heavy duty work.....

    the 12V71 would be a beast.

    I always have wondered about them. They are "only" 852 cubic inch, which is essentially the same displacement as a small or big cam 855 Cummins of the day. My guess is probably more horsepower than its contemporary Cummins and Caterpillars but probably equal or less favorable torque curve too. I would have to think they are extraordinarily smooth pulling engines. A 4 stroke V12 has a 6 power strokes for every crank revolution, or every 60 degrees. Versus 3 or every 120 degrees for an inline 6. A 2 stroke V12 is getting all 12 power strokes every time the crank turns, or 1 every 30 degrees. Like I said, I would have to think they are incredibly smooth and probably have a very different feel versus a typical I6. I would like to drive something with one it someday just to see but probably wouldn't want to own one. I have a friend who pulled very over length and overweight precast bridge beams with a steerable jeep in the rear back in the late 70s and early 80s when they were finishing the Interstate system around here. He ran a Kenworth with a 1693 and later a transplanted 855 Cummins of some variety. He ran with a guy who had a 12V71 in something pulling the same loads all the time and he says the two of them were always pulling grades at the same speed and they were about equal in performance. I have no other knowledge of their trucks' specs but that what his story. Have you every run one empty or loaded? If so what was your experience with it?

    My Dart has one and it is listed in the sales lit as one of the engine options.

    Have you ever posted pics of this truck on here? You have mentioned it in several threads and I was wondering what it even looked like. I never heard of them until you mentioned having one a while back. Maybe you could make a new thread in the other makes section.

  5. Not to hijack the thread but does anyone remember the Mack Freedom which was the next iteration of the Renault midliner? I think it was actually called a Renault Midlum. I think only sold for 2 or 3 years in the real early 2000s? My guess is when Volvo took over it was dropped....

  6. I know one thing. Getting assassinated by  a sniper while having a conversation about shooters is beyond crazy. Almost like it was planned to happen that way. I hope they can track down and investigate that kid who he was conversing with when he was killed to see if there was collusion with the shooter.

    Investigators say they found a 30-06 bolt action Mauser hunting rifle in woods nearby. Hmmm. The photos they put of the suspect ascending the stairs presumably to his shooting position doesn’t show a person packing the rifle they describe. I get he was wearing a backpack but I doubt  even a break down Mauser action hunting rifle would fit in a normal school backpack. I’m skeptical the rifle they found in the woods was used in the shooting. I think it was placed there to throw off investigators and prolong the manhunt. Why take it with you while fleeing the campus and risk being seeing shlepping a 30-06 hunting rifle the whole way only to discard it once you get to cover? Hmmmm.

    if he wasn’t packing it in when the photos were taken how did it get up on the roof and who unlocked the doors for him? I doubt the college leaves access to building roofs unlocked for students to go sightseeing. How did he know Charlie would be setting up there and that location would be viable for a shot?

  7. Lots of MS200 manuals and books on Ebay. If I remember correctly the Mack dealer parts system has not supported the midliner trucks for many years. Information on them is all but gone it seems. There is probably a source in France that knows about them and/or can get parts. If you can read/speak the language and do the digging.

    only to hear from driver "it doesn't shift right . big difference in ratios" well next time steal a different Transmisson .

    Yea he should have stollen the correct duplex 🤣. However, he was not wrong. If you look at the ratios between a direct and over gear triplex the difference is not insignificant at all. If your truck had rears geared for one, then swapping to the opposite transmission would readily apparent.

    If it's a double over, wouldn't it need to have the compound in overdrive before the main goes in fifth, and forth to fifth in a double over would be a lot less RPM difference than first through forth. (almost like a split in the compound)  In reality, 3rd over to fourth under is probably a tiny downshift.  Might try third over to fourth direct ?   😳  This is going off forty year old memories, so I might be a little off. 

    Yes I think so. If its a double over (TRT-720) then the main is direct in 4th and 5th main is a real small overdrive. Below is the ratios for a TRT-72 non overdrive triplex with the 5th main direct. The only OD is 5th high split because high split in the auxiliary is 0.85:1.

    Ok,I`ll try that,thanks.Haven`t done a lot of splitting yet.

    It will probably take some practice as it is somewhat counterintuitive. If your in say, 3rd hi split and want the next incremental gear (4th low split), you would, like you said, take the main out of third and let the rpms fall way down to get it into 4th. Then, immediately take the auxiliary out of high split and bring the engine rpms way back up to just under where you were before you shifted the main, and put the auxiliary into low split. Then the next would be a small, "normal" shift of the auxiliary to direct. Then again, a small, "normal" shift of the auxiliary to high split. Then it starts all over again my shifting the main from 4th with a big rpm fall to 5th then immediately following with a shift of the auxiliary, with a big rev match, from high split back to low split. I was always told to never shift both levers at the same time when learning, which is why there is a huge rpm gap when shifting just the main to the next higher gear but I have seen videos of old timers shifting them both at the same time and seemingly never missing a gear. It looks very laborsome shifting both at the same time as one hand pretty much has to be through the steering wheel with your wrist steadying the steering wheel and one palm on each lever. I'm sure it became second nature back in the day to the drivers who drove these things daily fully loaded. As an antique bobtail or hobby truck I think its easiest to leave the auxiliary in direct and shift the main as a normal 5 speed and then when you get to 5th if your on the open road and want top speed you can move the auxiliary to high split for cruising. Below is a good video of a guy shifting one, one lever at a time as I described. I believe he starts out with the main in 2nd as he is just bobtailing......

  11. Someone with experience driving one can chime in but I think what you’re noticing is correct. Once you catch 4th like that you would immediately shift the auxiliary from hi spilt to low split which would bring you back to about 200-250 rpm lower than where you were before (3rd main, auxiliary hi split) you shifted into 4th…if you were loaded.
