Sherman Tank Site News, POST 11: New post, and new Manuals to download.

Sherman Tank Site News, POST 11: New post, and new Manuals to download, more updates to come.

Spring and summer are always my busy season at the day job, so the amount of time I’ve had to really spend on the site has been a little limited.  I have been collecting data for further Sherman posts, and part of that is technical and field manuals.  I’ve collected a bunch of new ones and they are all available on the downloads page

I also just put up new post on the A-65 V12, Chrysler’s unadopted monster Tank motor. 

As the summer comes to a close, I should have more time to dedicate to the site again,  so watch for more posts, more often in the coming months. I am also considering setting up some form of donation page, things are a little tight right now, and It would be nice to offset some of the costs, and or have a little money to pic up a couple of pricey manuals.

Check out this cool video of Nicholas Moran AKA the Chieftan, talk about why the Sherman was the best COMBAT TANK of WWII.

Thanks for checking out the site, and any feedback given!

Watch David Fletcher talk about the Vc Firefly

#68 The Chrysler Engine that could have been: The A-65 V12, Chrysler’s home designed tank motor.

The Chrysler Engine that could have been: The A-65 V12, if the war had gone on, there could have been some hotrod Shermans.

Chrysler Corporation had a big impact on the war, and US Tank production. They produced the first, and the model for the others, Tank Arsenal CDA.  They also came up with the A-57 multibank tank motor, that powered a significant number of Sherman tanks. They produced this fantastically complicated, but also reliable motor in a very quickly, and even though the US Army and Marine Corps thumbed their noses at it,  it was well liked by the British.

Chrysler on their own dime came up with a water cooled, V12, tank motor, and offered it to the Army.  It took them about a year to come up with three trial motors.  These 1568 cubic motors started out at 650 horsepower at 2600 RPM and 1485 pounds of torque at 1600 RPM on the test stand.  They came in around 3840 pounds, but there was a proposed all aluminum version that have dropped nearly 1000 pounds.  Designing and producing the prototypes, cost a grand total of 358,000 bucks, that’s over 5 million in today’s dollars. During the dyno testing period, they had a few problems with the fan drives, but these were solved with improved oiling and rolling bearings, and these seemed to have solved the problems.

They used an M4A4 as a test vehicle, and had to stretch it another 9 and 1/2 inches to fit the new motor. Installed and ready to roll the thing came in at 69,170 ponds, and a stock M4A4 came in at 69,640 pounds!  Installed, the early versions had 549 horsepower, but they upped the compression ratio and got it to 580, and it was improved even more with some carburetion changes. They made the compression change by swapping and a cam change during the in vehicle testing phase. Further testing led to the intake and carb changes.  All the while the motor was being swapped in and out, and driving tests done.

The automotive tests were very successful, and that was using the stock powertrain of the Sherman, though with so much power, they decided a gear change would help. By swapping the original 3:53:1 gears for 3:05:1 gears, they A65 was still able to beat an M4A43 in a drag race!  The engine was so promising, it’s an interesting mystery why the Army never developed it further.  Much like the GAA, there was much more performance potential in this motor, and the Army never took it any further.

I suspect what ultimately killed this motor, was the same thing that killed the GAA, the Army was looking at air cooled motors for the future, because you can save a lot of weight, if there is not liquid cooling system needed.

Special thanks goes out to Chris R, one of our readers and a source contributor, sent me a nice little history on the motor.  Thanks again Chris, sorry it took so long!!

US Army M4 crew, probably somewhere in the ETO or MTO. The crew are wearing a  HBT coverall that was not all that popular. Later they would would wear the same things the infantry did.  Being color you can see the black on OD green camo used, and a red air ID panel on the back of the tank. The top hat was not standard issue.

An M4A2 75 large hatch tank, this is one of the rare dry ammo rack large hatch tanks. It must have been going pretty fast when it hit that mud, note the tanker bar on the left about to fall off.

This is an M4 Sherman in Italy that hit a large Anti tank mine, or maybe a pair of them in the same hole.  The tank is a DV tank, with an M34 gun mount.

This picture was taken during the staging in the UK just before 6 June 1944. Note the left-hand tank has the characteristic arm for mounting a dozer blade (barely visible running along the suspension); the hydraulic jack and blade are missing. 741st Tank Battalion after action reports indicate that among the eight dozer tanks they had scheduled to land in Wave 2, one of them, commanded by LT Kotz, did not have a blade attached. The 741st’s tanks on Omaha Beach came in three flavors. B and C companies had DD tanks. Co. A had M4A1 tanks and the tank dozers (six of their own and two from the 610 Engineer Company) were M4A3s, if I am not mistaken. If these are 741st tanks, then the photo was taken at the Portland ‘hards’ in the UK, where they out-loaded. Also note the M8 armored ammunition trailer. Each of the eight LCTs carrying Co. A embarked two standard tanks and a dozer tank. They also carried an engineer gap assault team and towed an LCM behind. Off the Normandy coast, the engineers boarded their LCM and followed the LCT ashore, where the dozer tank was supposed to support and work under the direction of the gap assault team leader. Also, on the way in, the two standard tanks were to fire over the LCT’s bow ramp, providing suppressive fire as they neared the beach. The ammo trailers were there to ensure they had plenty to shoot. One pair of Co. A’s tanks reported firing 450 rounds of 75mm on D-Day. Love your site. Caption Info, thanks to Chuck Herrick.

M4A3 or A2 76w Sherman somewhere in Europe 1945, that almost looks like Soviet numbering on the side of the turret.

Soviet M4A2 75’s crew play an accordion and pal around. This tank is another rare large hatch hull with dry ammo racks, you can make out the armor over the ammo racks on t he side of the hull. Most, it not all of these tanks went to Russia. Also note the drivers side head light and guard are nearly ripped off.

Convoy of tanks, trucks and jeeps from the100th ID, and 781st TB, the photo isn’t detailed enough to get a specific make on the Shermans. 
Шерман-1
This M4A1 76w is from A Company, 20th Tank Battalion , 20 Armored Division. They are on the outskirts of Cailly, France on February 24th, they had arrived in country a few days before and had not seen combat yet. The crew is unpacking and taking inventory of all the gear issued with the tank, they probably received the tank with the back deck covered in the boxes. 
Looking for info
A group of Doughs gathered around the rear of an M4A3 76w, probably somewhere in Germany in 1945. Note how much stuff they have strapped to the back deck. 
Okinawa_1st_TB_USMC_4-45 (1)
1st Marine Tank Battalion, Okinawa 1945. notice all the extra stuff on the tank. The Marston matting on the hatch is to keep the Japanese infantry from putting a satchel charge or worse right on top of the periscope, a fairly weak spot. They also had magnetic mines they could put on the side of the tank on I bet  the matting on the side helped prevent that. Wood and concrete was also used. It must be the angle, but the pistol port almost looks like it’s missing.

A French M4A3 76w or M4A2 76w of second company of the 501st Tank Regiment. The French used almost all versions of the Sherman, so without seeing the engine deck, I can’t tell for sure what model it is.

M4 Sherman tank named Bell of Little rock, and a Lt R Hoffman looking it over, January of 1944, oddly I can’t find out what unit this tank was with. 
Шерман-с-песком (1)
This seems to be concrete going over sandbags. The tank is either an M4A1 76w or an M4A3 76W. If you have any other info on this image let me know.
NARA_-_196225 (1) burma
M4A4s on the Burma road. How cool is it to see M4A4 tanks on the Burma road? These M4A4s were probably fairly late production A4s, that had been used in the US for training then overhauled and shipped to the UK. Some M4A4 tanks ended up back in US hands in the CBI when a composite US/Chinese tank unit needed some mediums.  Not the lead tank has some kind of windscreen up for the driver and how heavily loaded the tanks are.

Behind a destroyed British Sherman M4 near Caen in Normandy, a fascist  soldier, of the criminal, Waffen SS watches the enemy line. Date: 1944 The Tank if either an Ic or Vc Firefly, probably the latter since it was the most common Firefly type.
M4A2 76w Lend Lease tank
Our Soviet allies(at the time) using a Lend Lease M4A2 76w. I have no idea what unit these Russian Soldiers are from, but if someone does, let me know. I bet they killed a lot of Nazis to get to there, there being somewhere in Germany 1945
Soviet_Lend-Lease_M3_Lee_Grant_And_German_Soldiers-2
Soviet Lend Lease M3 Lee knocked out. The Germans on it seem to be using it like a jungle gym, though something less wholesome could be going on since some of the fascist, criminal, invaders are in various states of dress.

This British M3 Grant Crew is setting up to spend the night in the desert, in egypt, in 1942. I do not understand why two of them are naked. Note the .30 1919 on the roof, and the canvas mantlet cover on the 75mm.

Clearly tanks and bridges are not fond of each other. This M4A3 76w HVSS tank seems to have been a tad much for this one. It was also a German bridge, so it was probably complicated, just adequate for the Job, and prone to failure. =D

Another shot of the prototype Lee at Aberdeen Proving ground.

Another Lend Lease M4A2 76w being used by the Soviets. These tanks were well liked by the Russian crews, they felt they were very lavishly equipped. They were not fond of the .45 ACP round or the submachine guns that used them, and that these tanks came with. 
20090625-vena
Even more Russian M4A2 76w tanks, the Russian crews called them ‘Emchas’ and they were unhappy to have to give them up when the war ended. In some case they didn’t, and converted them to tractors. 
Soviet_sherman1
Even more even more Russian M4A2 76w tanks, of the various engine types the Sherman could come with, the only ones the Russian would accept were the diesel based  M4A2 tanks.

French M4A2 coming off an LST, this one is with the 12e RCC, 2e Division Blindee. This was a very famous French Armored Division commanded by the General Philippe LeClerc. This photo was taken on 2 August 1944, on Utah beach. Vive la France!

#30 Sherman Model Specifications: Data, and Lots of It.

Sherman Model Specification Sheets: Detailed Data Sheets For Each Model.

These were a pain in the rear to make, the ones in the back of my copy of Hunnicutt are very bad, so I have reproduced some in Word, and then print them out as PDFs, then take a screen shot of the PDF for this post. I have now hosted all the PDF files, if you want something with copy and pasteable text. I’ve got a system not for these and it’s semi easy to do, so I will keep adding them. I also added at least one, and up to five images with each spec sheet, of the Sherman the spec sheet is for. You can click to enlarge all these images, the sizes very.
