    My primary goal in such historical analysis is the truth. This case is especially interesting because a proper analysis is new to me and because it appears to be one of those beleaguered "myths".

    It is exciting to know that certain people of the past were capable of such performance against impossible odds, in times, where individuals became but insignificant gears in the machinery of industrial warfare. It is very unfortunate that they gave their best for a perfide regime, but those are some of the finest feats in the recorded military history.

     

     

    Trusting Nazis is no way to get to the truth, numbnuts.

    I wonder what's the point of this obsession with propaganda-driven made-up stats of several individuals leaving the other millions of common German soldiers looking like a useless inept crowd. That applies twice more if those individuals are hardcore nazi from SS. That's not only weird but also rather sick fetish. 

     

     

     

    Yeah, it makes you wonder if the pages of his Jentz books are stuck together.  It would explain why he seems so ignorant, hard to read pages stuck together with...

    Honestly, he's done more damage to my psyche than he knows. I'm beginning to doubt the truth of the Holocaust...

     

    Since he really admires Nazi technology so much, maybe he boned up on the only thing they were both technologically cutting edge on, and good at implementing. Mass Murder and the tools used to do it. It's easier to understand than a torque converter too!

    Definitely unexpected results! Interesting assertion about the reduction gear preventing the Pershing's torque converter from slipping and that the Soviets found it performed well on slopes. In Marine Corps Tank Battles in Korea, Gilbert says, "The M26 was a powerful vehicle, but as the tank crews soon discovered, if it stopped on a steep gradient the transmission would slip, and it was difficult or impossible to get it moving again. Help was needed and Eugene Viveiros, who, with one of the Headquarters Platoon [Sherman] blade tanks, attached himself to the 3rd Platoon, was ready to supply it. He was called upon 'to pat them on the butt end with the blade of the 'dozer tank to shove 'em up and get 'em going again. Once they got traction, then they were all right,' Viveiros explained." Although at least some Army Pershings arrived in Korea in need of repairs or overhaul, these USMC tanks were in decent working order (despite a shipborne flooding mishap en route), so this wasn't a maintenance issue: in a discussion on the state of Korean Pershings over on TankNet Ken Estes said, "...the USMC [Pershings] were drawn from depots, with no miles...all the USMC WWII flame tanks and postwar M26s went from storage through the depot line before being shipped to the units."

     

    Any idea what "average technical speed" means? Too bad the off-road test was cancelled; didn't General Fedorenko know that people would be arguing about these things on the Internet 80 years later??

     

     

    Maybe the hills of Korea were more extreme than what the Soviets used? It's an interesting question. Did the Marines lose any M26s to the well deck being flooded on the way to Korea?

    The transmission is also excellent! 

     

     

    The whole powertrain, (transmission, differential and final drives) seems to have been overbuilt, or very well designed for its weight class. The powertrain changed very little through its life, and rarely seems problematic on tanks being restored. Most of the time, if it had fluid, remained sealed, and didn't take a round through it, they need little more than cosmetic attention when a Sherman is being restored. This includes the one installed in the M4A3E8 tank used as a bulldozer, to knock down a large section of Oakland California in the 60s. It needed pain job, and they changed the fluid, and replaced some rusty bolts, that's it. 

     

    They also came apart in a easy, and were easy to work on. Everything used roller or ball bearings, probably all in sizes still available, and other than just the size, everything seems to have been easy to service. 

     

    The only major mechanical change during the war, was going from single to double anchor brakes, and I think the newer brakes could be retrofitted to the older unit. Compared to the weak junk the Nazi's produced it was really an amazing achievement in engineering.

    Soviet evaluation of Pershing in summer 1945 gives some light to the previously discussed terrain speed of Panther and Pershing. The result didn't favour Panther... 

    http://www.tankarchives.ca/2018/03/pershing-heavy-by-necessity.html

     

    This is the measured average speed in comparison with other tanks on the same terrain track. Pershing was the fastest of them in this test mainly thanks to its torque converter. 

     

    T26E3 - 18,9 km/h

    T-44 - 17,5 km/h

    M4A4 - 16,5 km/h

    Panther - 15,8 km/h

    IS-3 - 14,6 km/h

     

    Fuel consumption on the same track however showed that the torque converter made it also very thirsty, basically same as Panther. 

    IS-3 - 373 l/100 km

    T-44 - 378 l/100 km

    M4A4 - 503 l/100 km

    T26E3 - 585 l/ 100 km

    Panther - 595 l/100 km

     

     

    What's extra damning is the M4A4 does better tan the Panther!    The Nazi could only dream of having a motor so complicated, yet reliable!

    “76mm gun M1A1 and M1A2: an analysis of US anti-tank capabilities during WW2” 

     

    It’s a “historical piece”, but an interesting read nonetheless.
    @Jeeps_Guns_Tanks, there’s some schematics for the M93 HVAP, M62 APC, and M42 HE at the very end, if you don’t already have them. 

     

    Awesome. I do not have that report, or the schematics for those shells, at least at that quality.

    How does the engine make sure each of the cylinder banks are timed correctly? I assume the gear system that connects each bank to the main shaft could help, but I’m not 100% sure. 

     

    There is a giant firing order chart in one of the manuals, and I think you set the timing on each motor the traditional way, by twisting the distributer. I need to read through that section again.
