I do like the information of all the little details; It can get a little blah, blah, blah at times, but I'm learning a lot; More than I did when I was a tank driver in the Army.
8:10 Being harder to climb up on is really a disadvantage when you're trying to climb up to your own, open topped turret. When the enemy infantry is trying to get up there, it might be a bit of an advantage. However, this is an open-field gun, rolling with the heavy armor. (I.E. not a good Urban Assault Gun for obvious reasons: Buildings, with roofs, and possibly upper floors.)
@@SportbikerNZ Some people just don't appreciate that for mobile warfare you need to put an AT device on tracks. Nowadays they use an APC for the role.
@@Train115 wow. Yeah there is still the awesome Patton museum in Ft. Knox Kentucky. Several great AFVs and tanks. When I was 11 my dad had a small trucking company and had government contracts. We were able to get behind the scenes at many secure places on military bases. Knox was 1. They had a lot full of foreign tanks they used for study like penetration testing and identification for tankers Then they used them for targets. I've sat on and in some amazing vehicles. Fun story- he hauled a Mercury space capsule from Johnson Space Center to a museum that was being built It stayed in his warehouse for a year and I played in that thing the whole time. Very cool childhood being around all the military people, vehicles and gear. Thanks for the channel tip. If you can get to Benning you gotta see the 28. Its amazing.
The engines were lc and la for clockwise and anti-clockwise rotation of the crankshaft. The 71 series engines could be produced In either variant by changing the cam, starter p, oil pump and if i am not mistaken the crank and supercharger blower but all other part# were the same (block, pistons, heads, etc). If you have two crankshafts outputting to gears engaging with a common flywheel, they need to have opposite rotations.
to add to this: if the connection between the crankshafts and the common flywheel is a simple cog system, the engines would indeed have to have opposite rotations. if it is a more complex cog system, or a chain/belt system, the engines wouldn't need to have opposite rotations. the advantages of the former are that it is more reliable as there is less parts and the power transfer is more direct, the disadvantages are that there are 2 types of engines and 2 sets of parts. the advantages of the latter is that there is 1 engine type and 1 set of parts. the disatvantages are that it's less reliable due to the number of parts and that the power transfer is not as direct.
A simple thing to keep in mind about the 18" wall. For all practical applications outside of other tanks you're in a tank, you can blow it up. She had the clearance for running across railroad tracks.
Been asking myself that as well, especially when there are far more interesting sounds from the tanks themselves... but it is a sickness here on youtube, have a hard time finding any good tank-clips not ruined by utterly pointless "music".
My great grandfather was an infantry unit during WWII and he once told me a story of when he once saw a Achilles MK-I slam into a M4 A1 Sherman he told me that he had no idea what was going on but he said that the crews in both tanks had a small brawl and were in some serious trouble. There are many more details but that's the basic's.
Reference the engines labelled LC & LA. C is for clockwise & A is for anticlockwise, as they were contra-rotating & thus would have mirror image cams & other parts that weren't interchangeable.
@14.12 You have two engines and certain parts wear differently inside an engine. Therefore they're not identical. For example, if you had to strip the heads down on both motors, you'd need to know which push rods came from which motor and from which cylinder. They'd have the left or right motor marked on them for that reason and you'd lay them out so and even push them in a line through a bit of cardboard so you'd know which cylinder they came from. It's a bit like a self loading rifle, you can't just put another breech block in it because every rifle breech block wears in differently, even where the rifles are all the same model so if you need to replace one you have to machine it first. Similarly you can't just put the push rods (and other bits) in a motor back in any old order you like or you could end up with a real mess on your hands.
@Funk Enstein yeah dude lol i remember posting on the world of tanks forums back when they started making these videos and that was one of the first comments... sigh
if you look at the heads on the engine both manifolds are on the inside which means the left engine rotated the opposite direction of the right at least that's what my grandpa said who was a crew member on one
I don't think anyone in the 40s assumed that teenagers in 2018 would be obsessed with AFVs. WoT is one of very few games that successfully incite learning history, it's impressive
At 14:10 into the video he expresses confusion as to why the two engines were labelled LC and LA. Looking at the handed nature of the pair I would have thought that C stands for Clockwise and A for Anticlockwise, meaning that the engines rotate in opposite directions. Many of the engine parts would have to be different because of this. Just a thought...
Bloody late comment but never mind. My father was a heavy diesel mechanic for decades. Apparently, the old 2-stroke Detroit diesels (GM’s diesel division until about the late 90s) that he used to work on and drive were capable of running both clockwise and counterclockwise and parts had to be ordered accordingly. I suspect that it’s entirely likely that one engine ran one direction and the other the opposite, either both crankshaft spinning towards the center or both spinning outboard. For. Reasons. Just a thought.
In one of the best war comedy movies, Kelly's Heroes, there is a character 'Little Joe'. There was also 'Big Joe'. Was 'Little Joe' a reference to the tank wrench?
If you head over to bus greasemonkey .. these engines GMC diesel engines were used on the greyhound silver side busses of the era.. sturdy and reliable.. and super simple to repair.
Can you give any details on the applique armor used by the British? Zaloga is of the opinion the amour kits were never actually made, I wonder if they were "official" kits, or spare armored welded on in the field.
Found it interesting that The Red army received no more than 52 M10 Wolverine TD's. All through the Lend/Lease Program!. They were attached to the 3rd. Byelorussian Front/5th Guards Tank Army/29th. Tank Corps/1223rd S.P.A.R. Artillery Regiment. Equip with the 76mm M7 gun and a 12.7mm Browning HMG. "see Allied tanks of WWII- By David Porter". Interesting historical note is that Audie Murphy was issued the Medal of Honor for Battle of Colmar Pocket, in a burning Wolverine. Using the 12.7 Mg to rip apart the advancing German infantry, halting there advance.
If I remember correctly on the inline Gm diesel engines( aka Detroit Diesel) .the LC and LA codes designate their arrangement and rotation. The "L" means left hand rotation, and the A and C has to do with what side the intake and exhaust systems are located.(among other things) The Gm 2 strokes were very well designed and versatile and had a long and fruitful existence., and millions are still in use around the world today. But D.D. is now owned by Daimler Benz. Most parts do exchange between the different orientations in the same series and were every bit as universal and exchangeable as the famous small block was, but because of the numerous orientations, some parts end up being mirror images of each other thus are not interchangeable. In a side by side tandem drive situation like this you would normally have the blower and the exhaust on the the outboard side allowing for a closer pairing of the 2 engines.
I wonder if the vehicle markings (mix of US Army style on a British vehicle) reflects sometime in the past this vehicle was repaired, recovered or otherwise separated from its original unit and got reprocessed or in some postwar era, someone tried to paint it a war time look and didn't realized that it was a convert.
That music i believe is on my janes flight sim, or my usa f16 flight sim, many a bombing or rocket run have i made, i fondly remember my thud dropping ordinance for the jolly greens, great memories.😎
Isnt "Little Joe" also what they call the auxiliary generator motor? Thats confusing. And didn't all armor in Normandy get at least one white star in a circle painted on the turret roof as an aerial recognition symbol to help Allied fighter bombers from mistaking them for panzers? The M10 has no roof, which might explain the star on the sides. Or maybe they just screwed it up. All I know is that I built a model M4 Medium years ago, and it had British markings and a star on the roof. I am pretty sure I put the decals on per the instructions, and I seem to recall reading that explanation at the time. It wasnt just an American marking, it was the easiest, most visible Allied marking they could think of. EDit: From Wiki: *Allied star* A five-pointed star, painted white, was used to identify Allied vehicles from 1944. British tanks rarely had stars on the front or sides, normally just one on the rear of the turret. AFVs often carried stars on the sides and rear. Softskins normally carried stars on their sides. The star was normally 8-12in and was stencilled with a point upwards. So stars isnt always American markings, although it may be in this case. I thought the circle was the main difference.
That engine config is crazy, two diesel engines smacked together with a common crank output. Looking at it I thought he must be wrong and it must be a V-12 since you can see the valve train in two rows of 6, but upon looking it up it actually does have two vertical I-6s. Another weird thing is the lack of a valve cover. You usually do not see all the valve work for an engine sitting on top, unprotected like that.
And the LC and LA prefix for parts would be because they are mirror images of each other but rotate in the same direction opposite of aero engines that are not mirrored but rotate in opposite directions.
Many armoured vehicles of the time had two engines more or less separately. The Churchill's flat-12 was two engines put together, the Matilda II and Chaffee had twin engines - and the Australian Sentinel ran on three engines feeding a shared gearbox.
because it's just a self propelled anti tank gun, in British service it was used by the royal artillery corp, they liked the ability to see and observe
@ Storm Morgan: Yes, you have it right: The Archer tank destroyer was build on the chassis of the Valentine infantry tank chassis, mounting an Ordnance QF 17-pounder gun firing rearwards back over the engine compartment. It was well-liked by its crews, being of low silhouette and packing a punch.
ARRRRRRGGGGGGG!!!!! Background music pounding at brain. Disorientation! Aggravating beyond human tolerance! MUST ---- LEAVE ---- UNFINISHED ----- CAN'T WATCH ----- MUST LEAVE NOWWWWWWWW!!!
+Sgt Bones They were removed. The two long thin panels happened to be off for maintenance at the time I was filming, and I decided to leave them off to show the engines.
+TheChieftainWoT Thank you sir for that information. Oddly enough I had to look long and hard through the internet to find a decent picture of the valve covers, almost no footage shows the engines mounted in the vehicle itself, and all photos seemed to be of them in maintenance. I actually found a video of the same engine in a Higgins boat with the valve cover in place. But that was a boat, obviously! So again, thanks for the information. Keep up the good work! Hell on Wheels Sir!
+Sgt Bones I'd put that down to the general disinterest people have for the actual mechanical workings of the tank(s) in general. As Nicholas pointed out in his overview of the M56 Scorpion, people in general are more interested about the gun and combat history, so I suppose the more "niche" (for lack of a better term) interests are not really catared to in the same way, which is a bummer. I love learning everything I can about tanks, down to the nitty gritty. +TheChieftainWoT thanks for your stellar work!
+Friendly Fire Gaming Agree with you completely there, I belong to the niche type of person ever since helping get a Chaffee back to running condition at Ft. Hood Texas, back in the 80's while serving in the Army. And as a model builder I do tend to be interested in more information than most folks when it comes to the interior and inner workings of armored vehicles. That is why I love watching these Chieftain videos, since he always tries to present as much information as possible.
Sgt Bones You lucky sod. Myself I'm from Sweden and have yet to serve with the army or have the opportunity to work on a military vehicle's restoration. But a man can dream, a man can dream...
One quarter (about 6.4mm) of an inch steel is not going to stop a 50 BMG round. Even basic 50 BMG ball ammo will penetrate more than 10mm of rolled homogeneous armor.
I'm sure this has been said before but : It might be an idea to specify US or British gallons - there's a big difference. Like, uk gallon is some 18% bigger
the reason all parts had to be identified as LC or LA is because there was about 45 non interchangeable parts. the engines are mounted so close you cannot mount major components between them. this means blowers, starter motors, fuel pumps and other items that normally mount on the right now must be mounted on the left for the other engine. both engines were right hand rotation though.
Were there actually M4s with the large Turret fitting a 17-pounder? That imagine that would have made on of the finest Tanks in ww2, especially the M4A3 with thr Hvss and a Ford V8.
Not certain who decided to label a British TD as American but they did no research. The 601 TD was never part of the 5th Armored. The 628TD served as the organic tank destroyer battalion for the 5th Armored. As far as I know (might be wrong but don't think so), the 601st was assigned to Infantry Divisions throughout the war.
Yep. Those were first invented in 1899 and steadily improved. GM's Detroit Diesel 6046 was the state of the art when introduced in 1938 for use in streamliner passenger buses.
@@billwilson3609 Thanks for the answer, Bill. My confusion may be because two cycle doesn't mean the same as two stroke? Here you can see perfectly the arrangement of valves, rockers, pushers and springs. That is, it is a four stroke engine, because the two-stroke engines do not have the elements quoted. If you can clarify this...
@@Ferr1963 It's either one since it makes power on every down stroke. The ring-ding 2 stroke engines use two ports with reed valves on the cylinder walls where the top port sends in the air/fuel mix when the piston has the exhaust port blocked then is closed by the reed valve when the exhaust port is exposed to allow the burnt fumes to escape. The bus engine uses valves operated by a cam to open and close the reed valves for greater efficiency. You can Google Detroit Diesel engines to see if any webpages have cut-away drawings of that engine. They stayed in production for a long time plus were made as V-4's and V-8's.
@@billwilson3609 Thanks again for the clarification, Bill. Very educational. I'm going to look at those engines with a lot of interest, because my only experience with two stroke engines was with those of motorcycles, which are much simpler. Best regards.
an old M10 hull is on a bombing and missile range out in the far reaches of 29 palms. I blew it up a few times. Theres not a lot left of it. Theres a lot of unappreciated relics being used as targetry :(

True ,I wondered if they rotated in opposite directions hence c (clockwise) and a (anticlockwise) ?

A bit late to add this, but the reason why the engines were labelled differently is the intake and exhaust are reversed on one.
Yes, These Detroit Diesels rotate in opposite directions.
The M36 Jackson/Slugger would be cool to see.
I bet a good crew would have the driver help the gunner turn the turret by turning the vehicle and also keeping the glasius to the front.
Nick: Those look to be left and right hand engines. Maybe so they can nest tightly together? (Thus the "LC" and "LA" designations)
I'm guessing clockwise and anti clockwise.

ARRRRRRGGGGGGG!!!!! Background music pounding at brain. Disorientation! Aggravating beyond human tolerance! MUST ---- LEAVE ---- UNFINISHED ----- CAN'T WATCH ----- MUST LEAVE NOWWWWWWWW!!!
thanks for the great content
Anyone know if the engine seriously had no valve covers, or were these just removed to show more detail for this video?
+Sgt Bones They were removed. The two long thin panels happened to be off for maintenance at the time I was filming, and I decided to leave them off to show the engines.
+TheChieftainWoT Thank you sir for that information. Oddly enough I had to look long and hard through the internet to find a decent picture of the valve covers, almost no footage shows the engines mounted in the vehicle itself, and all photos seemed to be of them in maintenance. I actually found a video of the same engine in a Higgins boat with the valve cover in place. But that was a boat, obviously! So again, thanks for the information. Keep up the good work! Hell on Wheels Sir!
+Sgt Bones I'd put that down to the general disinterest people have for the actual mechanical workings of the tank(s) in general. As Nicholas pointed out in his overview of the M56 Scorpion, people in general are more interested about the gun and combat history, so I suppose the more "niche" (for lack of a better term) interests are not really catared to in the same way, which is a bummer. I love learning everything I can about tanks, down to the nitty gritty. +TheChieftainWoT thanks for your stellar work!
+Friendly Fire Gaming Agree with you completely there, I belong to the niche type of person ever since helping get a Chaffee back to running condition at Ft. Hood Texas, back in the 80's while serving in the Army. And as a model builder I do tend to be interested in more information than most folks when it comes to the interior and inner workings of armored vehicles. That is why I love watching these Chieftain videos, since he always tries to present as much information as possible.
Sgt Bones You lucky sod. Myself I'm from Sweden and have yet to serve with the army or have the opportunity to work on a military vehicle's restoration. But a man can dream, a man can dream...
Can you explain why the sides look the way they do?
One quarter (about 6.4mm) of an inch steel is not going to stop a 50 BMG round. Even basic 50 BMG ball ammo will penetrate more than 10mm of rolled homogeneous armor.
Little Joe? Wasn't that the name of the tank driver in Kelly's Heroes?
+Coffeehound No, Little Joe was an infantry men in Kelly's Heroes.
I'm sure this has been said before but : It might be an idea to specify US or British gallons - there's a big difference. Like, uk gallon is some 18% bigger
yes make inside the tanks video, all ways loaded with good information his videos are.
Is that engine missing its rocker covers?
The "Chieftain`s" videos are so much better then Richard "The Challenger" Cutland.
I know its so annoying that challenger gets bovington. his tog vid showed NOTHING of the inside exept into the hatch. no view of the engine deck....
the reason all parts had to be identified as LC or LA is because there was about 45 non interchangeable parts. the engines are mounted so close you cannot mount major components between them. this means blowers, starter motors, fuel pumps and other items that normally mount on the right now must be mounted on the left for the other engine. both engines were right hand rotation though.
Engines were opposite rotation,-"handed"
about time we get a new video.
Were there actually M4s with the large Turret fitting a 17-pounder?
That imagine that would have made on of the finest Tanks in ww2, especially the M4A3 with thr Hvss and a Ford V8.
No there was not
I can remember when I was young my Uncle showed me pictures of HIM in one of those. Might be the rine
Achilles was a Greek hero with a very big flaw in his invulnerability, what a jinx name!
At about 00:40 in this video:
*Don't forget to hold your breath!*
😊😊😊
Hi. Would mechanics do the maintenance he talked about or would the crew be expected to handle it?
why climb the wall when you can blast it or crush it??
Yanuchi Uchiha
Loud and a waste of limited ammunition
How much POL does a abrams need for comparison?
Like to see these guns compared and explained .
Do the engines spin the same direction or opposite? If they don’t spin the same way then a lot more parts would not be interchangeable.
Opposite rotation
Not certain who decided to label a British TD as American but they did no research. The 601 TD was never part of the 5th Armored. The 628TD served as the organic tank destroyer battalion for the 5th Armored. As far as I know (might be wrong but don't think so), the 601st was assigned to Infantry Divisions throughout the war.
Where is T55A part 2? Has it been posted yet or am I missing something? thx
Where is that museum you're at?
Bovington Tank Museum
do the Shermans
13:20 two cycle diesel?
Yep. Those were first invented in 1899 and steadily improved. GM's Detroit Diesel 6046 was the state of the art when introduced in 1938 for use in streamliner passenger buses.
@@billwilson3609 Thanks for the answer, Bill. My confusion may be because two cycle doesn't mean the same as two stroke? Here you can see perfectly the arrangement of valves, rockers, pushers and springs. That is, it is a four stroke engine, because the two-stroke engines do not have the elements quoted. If you can clarify this...
@@Ferr1963 It's either one since it makes power on every down stroke. The ring-ding 2 stroke engines use two ports with reed valves on the cylinder walls where the top port sends in the air/fuel mix when the piston has the exhaust port blocked then is closed by the reed valve when the exhaust port is exposed to allow the burnt fumes to escape. The bus engine uses valves operated by a cam to open and close the reed valves for greater efficiency. You can Google Detroit Diesel engines to see if any webpages have cut-away drawings of that engine. They stayed in production for a long time plus were made as V-4's and V-8's.
@@billwilson3609 Thanks again for the clarification, Bill. Very educational. I'm going to look at those engines with a lot of interest, because my only experience with two stroke engines was with those of motorcycles, which are much simpler. Best regards.
Finally Chieftain!
If you have a 90mm gun, you can make a lot of walls shorter than 18".
an old M10 hull is on a bombing and missile range out in the far reaches of 29 palms. I blew it up a few times. Theres not a lot left of it.
Theres a lot of unappreciated relics being used as targetry :(
Where?
Isnt that a IIC? That dont look like a IC turret to me
17 Pounder, but what was the caliber/diameter of the projectile???
76,2mm or 3 inches
Bloody hell was that superman spinning that turret haha!
Why do they have the rocker arm covers off that diesel? no way. Those rockers remain exposed during operation?!
I would honestly to know who thought naming a tank destroyer Achilles given the prominence of the term Achilles Hell it is like naming a plane Icarus and being surprised when it crashes
It's fine, Paris had already fallen when this was named.
