Heck The A model didn't come out until the late 1940s. If anything it should have been a Mack E model. Specifically an EH, which was a variant specifically built for the military.

I cleaned up the water pump housing and got it bolted on. The lower water hole was previously rusted out and a helicoil was installed. It seems ok and torqued down to 55ft/lb ok. I was concerned about my water pump and wanted to look at putting bearings in it. It didn't leak but when spun it had a looseness to it and you could hear a faint rumble from old bearings. The Mack manual shows how to rebuild it but takes a special puller to get vanes off the shaft. I played around but figured it would be better just to replace it. I googled and found a 673 version. The 300 is about 1/2" shorter shaft and no keyway for pulley. I am going to call on the reman version and have a known good pump. I'm taking crank hub to shop Sat to press it apart and machine it. Assemble the heads and get them home so I can get them set on. I made a list of silicone hoses to replace all the old lines that hook stuff together. Water manifold, intake, oil cooler, turbo. $100 at Summit racing. I did the same for the 237. Things should really come together this coming week.

So I was watching the movie "Patton" last night. Good movie, but I noticed a few vehicle and equipment mistakes. One being this B model Mack they had hook to a mobile war room. The B model didn't come out until AFTER WW2 from what I know. Still a good movie, just the inaccuracies only guys like us would even catch throws it off a bit.

on a positive note : if You put the igloo in those big cooler water jugs and froze it till next winter ;; you could sell it as a brand new 2026 model. and it's easier portable.

So wifey and I talked again... We both agree to forfiet the Earnest Money we put down on the Igloo Kit. It's the right thing for us to do. I hope March will produce more product for you to recoop your losses.. Jojo

early and I mean very early ; dynatard push tubes were same hollow tubes . the tubes were collapsing from this "new" exhaust brake from Mack. change over was exhaust tubes were solid. by '86 (long after my departure) the tubes must have been installed as solid. !!

If I remember correctly from his signature forum member @R.E.D is from Houston. Maybe if he gets on and see this he can point you toward the work. For some reason I remember him having an early style Granite triaxle dump truck.

I just searched Mack MD electric on facebook and I don't see any pics of one with a Volvo cab?

Well have a swinging time bud when you get to it and best wishes… bob

rockers cam and push tubes!

My 237 had 1/2" stems, as the lash caps for the Jake's will work perfectly on the 300. I never had valves out of 237 so don't know if it had seals? The 300 heads definitely do have seals.

Happy Birthday 🎂

Yes. If I'm not mistaken the CH/CX is 33 and a half inches wide too. Never intended for anything but raw Mack 6 cylinder power.

Heresa old one me stirn the R model mack cya

Happy birthday Heinz... have a great day. Paul

At least your keeping busy Paul..... Paul

I am wondering what the differences in the heads between a dynatard E6 4 valve and non dynatard e6 4 valve? My 1987 R688ST has a late '86 4 valve E6-350 with non dynatard heads and was wondering what it takes to make them accept dynatard components. I thought I had read the exh valve seat depth was deeper and the push rods are different. I would like to clarify that prior to having the machine shop go through my non Dynatard heads. Any help would be greatly appreciated. Thank you.

Thanks Joey, been wide open today, so far this week, and probably tomorrow. I might get to rest Saturday, maybe.

The U.S. Department of Housing and Urban Development on Thursday proposed a rule that would limit public housing mostly to U.S. citizens and green card holders. The rule limits funding for those in public housing and other HUD-related housing to citizens and eligible non-citizens. The rule would require every resident in HUD-funded housing to show proof of citizenship or eligible status. The measure would effectively bar families that include illegal aliens from housing. “Under President Trump’s leadership, the days of illegal aliens, ineligibles, and fraudsters gaming the system and riding the coattails of American taxpayers are over,” says HUD Secretary Scott Turner. “HUD’s proposed rule will guarantee that all residents in HUD-funded housing are eligible tenants. We have zero tolerance for pushing aside hardworking U.S. citizens while enabling illegal aliens to exploit decades-old loopholes.”

has anyone seen any more about the assination attempt on Ilan Ohmar. Seems like that story came and went.
