Inside the Chieftain's Hatch: AEC Armoured Car, MkII, Pt 1

[Error: In this case, red bolts = "Mechanic use only". I guess you had to remember which bolts were reverse-thread!] The Associated Equipment Company decided to make a wheeled tank. The initial version with a Valentine turret and 2pr gun was replaced in production by the Mk II, with a 6pr. This example is located in Bastogne Barracks, and is part of the Belgian military's War Heritage Institute collection.
This is the first batch where I have invested in bringing along a cameraman/editor, goes by FixItInPost, and as you can imagine, he doesn't work for free. Any financial support you can throw in below would be greatly appreciated. This was a test case to see if it's economically viable.

The coloured nuts (usually red) are to indicate that they are not to be undone by the user. This is because they are holding the two halves of the split rim together and undoing them is not how you take the wheel off the vehicle. It is how you split the wheel into two halves for changing a tyre without having to use tyre levers and a huge clamp.There is a potential danger in undoing them if the inner tube is pressurised so they are coloured as a warning to leave them alone. Other things that should be left alone may also have paint applied to the fastenings such as the drive flange bolts.

1) Lotsa stowage - just what you need for a recon unit in the desert. 2) AEC built the iconic London double decker busses. I would think that with all that milage behind them, the armored car engine would be well proven with any bugs fixed. 3) Some history "Mark I: AEC 190 diesel engine, Valentine Mark I/III turret with a 2-pounder, coaxial Besa 8 mm , Bren AA, crew of three, 125 built. Mark II: AEC 195 diesel (158 hp) engine, 12.7 t, heavier turret, QF 6-pdr (57 mm/2.24 in), coaxial Besa 8 mm (0.31 in), Bren, crew of four. Mark III: Same engine, ROQF 75 mm (2.95 in) main gun and the secondary armament as previous versions. Designated Close Support Armoured Car. AEC AA variant: Tested with a Crusader AA turret for operations in Europe, but never produced" "AECs were mostly used in the latter part of the campaign, until the end of the Tunisian campaign, by British forces and the British Indian Army, in complement to US-built Staghounds. These vehicles also participated in the operations in Italy, while most Mark 3s served in Western Europe, Northern France and the Low Countries, until 1945. The AEC remained very influential, and was kept into service until 1958, when it was replaced gradually by the Alvis Saladin. The Lebanese army purchased some vehicles, that were used until 1976" " The authorised org for an Armoured Car Regiment (WE III/236/2 of Nov43) was based on RHQ, HQ Squadron and four Squadrons. Each of the four Squadrons was built around five Troops, each of two Daimler armoured cars and two Daimler scout cars. Also in the Squadron was a Support Troop (a small rifle element for dismounted duties), a Heavy Troop (two AEC armoured cars or two halftracks mounting 75-mm guns), with both of these Troops also having a scout car. Squadron HQ was to have four armoured cars (one Daimler and three Staghounds) and a scout car. The outline given in the FOW blurb suggests a shift to six pairs of scout cars and three pairs of armoured cars, the latter also with a scout car per pair. Assuming all other elements of the Squadron were left unaltered, that would need 15 scout cars and 6 armoured cars, against a WE of 10 scout cars and 10 armoured cars."

I was able to meet up with my Grandparents yesterday because they were in my part of the country, we met up at Bovington and it was fascinating to be able to go around there with somebody who spent his entire life, working with metal. Fabricating and repairing anything from horse-shoes to cement mixers. He especially has had experience dealing with tracked vehicles and conveyor belts of various forms. He really appreciated me being able to point out where the tracks were tensioned on lots of different tanks! He also made a very interesting point about the M48 drive sprocket. He says that the track doesn’t engage around that much of the sprocket maybe as opposed to some of the other tanks, similar to a Caterpillar Bulldozer. He says that this is a good thing because less engagement allows for more stretching in the track before it starts to cause a problem with the sprocket binding up. This made me realise that there is a lot more that goes into something such as track design than we might take for granted

[@johnfisk811]

This AEC turret with the QF 75mm ROF gun was also fitted to the Staghound armoured cars in place of the as built American one with the 37mm gun. With that and leftover ex Grant 37mm guns the last Humber and Guy armoured cars were made with the 37mm guns in place of the 15mm BESA. Trivia but, when the new Sudanese government went shopping for ‘tanks’, AEC wanted to do them Staghounds with the AEC turret and the QF 75mm but the ROF had stopped making them so they cut the mantlets etc. off scrap Sherman’s and welded them to the AEC turrets with the M4 75mm gun and did the deal with the Sudanese buyers. Allegedly they provided the buyers with one bill at tank prices for the Sudanese treasury and another for the actual price to the buyers who then pocketed the difference. Allegedly. The AEC turret and QF 75m gun was still being used in Lebanon into the present century on Staghounds. May still be for all I know.

Red painted nuts are ones the crew have no permision to touch, White painted nuts are ones the crew are allowed to touch. White wheel nuts because the crew might need to change a punctured tyre/wheel. Red because you would be getting into mechanical components that only a Vehicle Mechanic is trained to work on. Red also warns that the red nuts hole together a divided wheel and they should only be ondone if all the pressure in the inner tube is released. White / red paint has nothing to do with Right hand or Left hand threads (reverse threads) The white painted nuts are on both sides of the wheel, and indeed the threads are Right handed on one side aand left handed on the other but BOTH are painted white. They are stamped with R and L on one flat to say which thgread they are.

The rod you originally called a tie rod is actually the drag link, that's what connects the steering box to the wheel. The rod that ties the two wheels together is the tie rod.

[@jayffemt]

[@nightshade4873]

As a studying Mechanic, and someone who went through a bit of mechanical engineering, i'd add my two cents that the splined portion of the crankshaft is called a "slip-yoke", as you said it is meant to compensate for the movements of the suspension, and furthermore, from what i can see, there is no Panhard Rod or any form of Linkages in which to prevent the suspension from moving forward or sideways/roll, so it seems to me that the only thing holding the Solid Axles in place is the stiffness of their Leaf Springs. to add, i am quite surprised that it uses a Frame to support the armoured chassis, i thought that it being an Armoured Car that it is constructed as a box with the components placed internally of the chassis with the undercarriage being open, though granted accessibility to those components would likely be limited and would also eat up significant internal volume.

[@patriot-renegade]

I believe Ian V. Hogg said of the AEC in “Allied Armor of WWII” "...the result was an armoured car armed as well as the contemporary cruiser tank. (Another way of looking at it, of course, was to observe that the cruiser tank was armed with nothing better than that found on armoured cars . . .)

For a WW2 armored car, the armor is great. Saladin doesn't seem to be any thicker finally (whether that means less protected is a different argument) and it's not like it's carrying a greater gun. Kind of shocked they didn't build more of them, to be honest.

[@herman7661]

The reason for bolting the armour rather than riveting may have been because the factory did not have riveters (skilled workers who can rivet things together) available. Britain, at that time, was building warships and mechantmen as fast as they could and welding ships was still a bit in its infancy, in the UK, at that time. The riveters were all employed building ships.

[@steveholmes11]

It's a commercial vehicle manufacturer. If you're building a bus or truck you'll be bolting bits on, for rapid replacement when servicing.

[@ResaFMkII]

AEC certainly has a unique aesthetic. It looks great from some angles but just plain odd from others!

[@whatnow9653]

It's aesthetic was intentional, it was so ugly the enemy could not force themselves to look directly at it without induceing physical pain. This also saved 5 Shillings trupence on camouflage paint over the total production run, allowing management to give each other a bonus of £1,000,000. Fun fact, if the allies had not won the war, all involved, including the tea lady would have been hung for crimes against humanity. They later went on to manage the design the Austin 1100 and 1600 for which they also continued to give each other bonuses right up to and including the day of bankruptcy.

[@vojtechhykys1466]

The reason why it is bolted instead of riveted is that rivets have a nasty habbit of tearring off and bouncing around the the inside when they are hit with HE. You can see that on many prewar and early war tanks, before we figured out welding. The Soviets were the first ones to start doing it, since they had goten the first hand experience with the Japanese.

I've always loved this vehicle. So glad it's being covered in a video.

[@hypergolic8468]

I'd suggest the unusual construction was as welding in the UK was a relatively new technology (yet to be applied on a massive scale) when this was built. We were still building riveted ships when the US was welding Liberty ships and the Germans welding submarines. Bolting the frame together with a weld, a pragmatic approach for both assembly and longevity.

[@quentintin1]

welding was a relative new technology at all when WWII kicked, especially electric welding, equipment was expensive and you required skilled workers to do good welds, whereas bolting can be done by any shmoe with a spanner not to mention that converting from bolted construction to welded isn't a straight 1:1, especially if you want to do structural & ballistic elements so it's additional work on the design side to make a proper welded thing

[@rotwang2000]

Just because it's an older tech doesn't mean it's necessarily bad. The old chestnut that rivets and bolts will pop out whenever a vehicle is hit, ricocheting inside is not entirely wrong, but it happened a lot less than most people seem to think. Proper rivets and bolts will not create projectiles inside the vehicle. Remember they were also used in boilers and heavy machinery and usually worked fine without becoming a general hazard.

[@slateslavens]

belt and suspenders for the win!

[@greendoodily]

Also, I would speculate that the reason that they used bolts rather than rivets is because peacetime AEC made buses, lorries, etc., so probably didn’t have any experience with riveting.

[@gleggett3817]

more to do with finite number of welders available. If you can get away with bolts and rivets, that leaves the welders available for other industries (eg warship) or components.

Not sure if this was covered further down in the comments, but the exposed splines on the driveshaft or propshaft is what is known as a CV (constant vocity) joint & is intended to allow the suspension to freely travel up and down without binding. This is extremely common on offroad vehicles and 4x4s & is actually a pretty effective and simple design.

[@SedatedandRestrained]

[@The_Modeling_Underdog]

It's not ugly. It has "character". Or something along those lines. Our buses in Buenos Aires were still using red painted nuts in the late 1990s, early 200's to indicate a split rim. Many a mechanic at the time went full "off with his head" when changing a tire, undoing the wrong nuts and the whole thing just disassembling itself in a loud air blast with any of the components maiming or straight KIAing the guy.

Certainly more flexible than the various portee vehicle/gun mergers.

That is exactly what the propshaft splines are for. Standard on any vehicle with a live axle, unless it uses a torque tube, which maintains a fixed distance. Although i suppose you could make one that telescoped if you wanted to. Don't need them on an independent suspension since the differential is fixed in place. Although i wouldn't be surprised if they still used them or some other sort of joint to give a little bit of flex to the system for chassis flex or heat expansion or whatever. Binding is bad in a driveline. I think the armored car makes perfect sense. You want faster and cheaper scout and recon vehicles, tanks are very maintenance intensive and unreliable, anything tracked is. As long as you don't need the off-road capability and don't plan on going into heavy combat, a wheeled vehicle with enough armor and armament to safely retreat from opposition is way more efficient and effective.

[@2217Video]

Being that it is a British vehicle, the term is "wing" or "mudguard", not "fender". In British English, a "fender" is the padded thing covered in rope netting that stops ships getting damaged when they rub against another ship or the dock.

CHEIFTAIN ! You missed one interesting technicality of the AEC. As you rightly say, it was based on the Matador. In putting the engine in the back it meant the gearbox was also arse-about-face, not wanting to redesign the transfer box, they gave 4x2 drive to the front steering axle and when 4x4 was selected the rear axle joined the party. Therefore, the only known front wheel drive armoured car !

Lefthanded lug nuts on the left side is still comon practice or heavy commercial trucks. The main frame rails on the armored car are also the same as heavy trucks.

Towing points are these holes in the ends of "side beams". This funny car can tow!

You may find it ugly but I've a soft spot for armoured car aesthetics & have been severely tempted to buy one on a couple of occasions. The Ferret & Humber MkII being my favourites.

[@FinsburyPhil]

It's got a sort of Mk.I Matilda hull, Churchill turret vibe going on.

We have an AEC Matador at the Gunfire museum in Brasschaat ;-)

One of the benefits of having vehicles like this - is that while the enemy is shooting at them - they are not shooting at you. .

red bolts = user no touchy. The outer ring is because it's a split rim. The 'inner' ring is the axle hub. Easy way to keep a soldier from touching something they shouldn't whilst in the field. Also, the 'steering arm' is a pitman arm, which is attached by a drag link/center link to an idler arm. Which in turn is attached to the steering knuckle by another tie rod. Automotive stuff has 6 different names for the same part. You know, just to keep things interesting.

Air Brakes are spring loaded and when you Loose Pressure the Brakes Are Applied! The Air Pressure keeps the springs form activating the Brakes!! Hence the nickname of Safety Brakes!!! (This is why you sometimes see a semi-truck sitting still right after it hooks up to a trailer with its compressor running, it is building up the pressure in the trailer's air flask....)

Opposing thread is usually opposite sides of the vehicle as they thought the wheels would fly off into the sun if they didn't oppose the thread to the rolling direction. Red painted threads on commonwealth vehicles indicate the threads that are not to be undone while removing the wheel from the hub. this is in a time where very few people owned a car let alone the young men enlisting in the military enough of them obviously blew themselves up undoing the bolts holding the 2 piece rims together while still inflated that this became necessary.

I always liked the look of the AEC Armoured Car. Kind of reminds me of a big strong rugby player or the like.

I think this is designed with the ruthless logic of a bus manufacturer: "We are not fancy automotive engineers, Herr Porsche, nor do we wish to create a legacy. We have put together a vehicle for blowing stuff up."

6:40 Note the notch on the female half of the splined portion of the driveshaft. It's likely that this example is missing a dust boot it would have normally had back in the day.

A lot of US heavy vehicles had left-handed threaded wheel nuts on one side until the 1960s came a long when people realised it was a bit of a waste of effort to do this. The most common marking was for a number of dots or an "L" stamped into the end of a left-handed threaded bolt, along with a very firm instruction to keep the nuts to the corner of the vehicle they were removed from. In general the use of a mixture of left-hand and right-hand threads for wheel nuts was a grade-one pain in the chair polisher for any number of reasons, including a mixture on the same wheel (talk about confusing)

It's...'purposeful'. Yeah, that's the ticket! As for 'it', I must have been born with it; I've been that way all my life!

The splines on the driveshafts are normal expansion joints. All cars and trucks with driveshafts have them, they're commonly protected with rubber boots these days.
