Inside the Chieftain's Hatch: Achilles Part 1

I love how The Chieftain takes the time to have detailed discussions about the tank in the comments. Very nice of him to do that for the fans.

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.)

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.

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.

[@armadussteel2489]

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.

[@U6kCtBuN]

then both the drivers were punished to listen to the abhorrent music loop for approximately 60 minutes

[@dmorrison7774]

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.

[@ravenouself4181]

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.

[@GARDENER42]

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.

[@joeroberts9502]

@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.

[@Evilroco]

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

[@juliet_whiskey6625]

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.

[@AmazingAce]

9:57 Little Joe was also the nickname of the generator that could power the turret and electronics when the engine was off in M5A1 Stuarts. Confusing.

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.

[@TheLookingOne]

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?

[@hawssie1]

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.

[@andrewmatters5436]

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...

[@zee_6801]

[@scottdaviesvk2sdx319]

A bit late to add this, but the reason why the engines were labelled differently is the intake and exhaust are reversed on one.

[@parkerguy3601]

Yes, These Detroit Diesels rotate in opposite directions.

[@numberpirate]

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.

[@numberpirate]

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.

[@MrOlgrumpy]

The engines rotate opposite to each other,valve covers are removed in this shot,

[@akmzd6938]

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.

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.

[@JudsonHall]

LA / LC ... Looking at the valve springs they are counter-rotating ...

[@myfavoritemartian1]

Nick: Those look to be left and right hand engines. Maybe so they can nest tightly together? (Thus the "LC" and "LA" designations)

[@jld772]

I'm guessing clockwise and anti clockwise.

[@seanmacuaiteir437]

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....

[@9thSapper]

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.

[@MrOlgrumpy]

Engines were opposite rotation,-"handed"

[@Christian---]

Finally Chieftain!

[@justforever96]

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.

[@SgtBones]

+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.

[@Handles-Suck-YouTube]

+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!
