WORKSHOP WEDNESDAY: StuG III transmission disassembly!

[@geoffreyscheuerman2378]

Beautiful engineering in that gearbox, a work of mechanical art. You guys are the best. 👍

[@JeffBilkins]

And then consider how many they built, plus the engines and everything: it was a crazy amount of machining to build an army. Especially when every part seems to be super nice and complicated.

[@geoffreyscheuerman2378]

Indeed​ some 20,000 Stug Iii's were built, the most numerous fully tracked AFV of the war. @@JeffBilkins

I love the fact we’re stripping it on auntie dottys curtains with lumps of wood and a couple of £30 hammers and punches I love Aussy mechanics similar to Brits . Keep up the great work, currently fighting cancer and this makes a fellow mechanic who can no longer do this stuff still feel connected.

Let's be glad they spend their energy on nice engineering and machining and not optimising for winning the war.

Hello Folks...i repaired a lot of different Transmissions, but this one is awesome ! So much is technically done to improve the comfort of shifting ! An Eaton/Fuller Transmission is not as half on parts as the Stug one . But very reliable. So good luck to you for the reasambling...do not change the directions of the Schalträder, even if they have the same size. They only fit in one direktion to funktion in progress. I keep my Fingers cross for both of you !!!!! Kind regards from Germany, Rudi👍🍀🍀🍀🍀

[@Rusty_Gold85]

The Germans were designing this sort of Transmission 80+ years ago? Amazing . Top work Beau and Steve

[@amcconnell6730]

Paper, slide rules, hand operated lathes and mills.

[@hanswurst-h3e]

thats the wartime version. there was a whole line so called "variorex" gearboxes in a number of vehicles, like half tracks and the early p3. That one had a gear pre selector with clutch initiated gearshift, in comparison the zf from this video is cave man tech

[@BenJamInn-q3o]

Everything the Germans did and had was of significantly higher quality.. and only Germany was performing quality control on every piece of equipment

[@BenJamInn-q3o]

Germanys low quality products is equivalent to 10x better than everyone else's best

[@Salamandra40k]

​@@BenJamInn-q3o Except german tanks would sometimes have over 30% failure to show rates on the front lines...because some parts were almost hand-fitted and wouldnt mesh onto other vehicles without fieldwork. Meanwhile, Americans had entire warehouses full of parts that could be assembled into tanks in hours and every single last piece down to the bolts could be interchanged because it was all perfectly machined and standardized. The germans didnt have that capability- period

[@andrewsteele7663]

I am gobsmacked, the detail the Germans went to at that stage of the war is amazing. I'm so looking forward to the next video, Cheers

[@obsidianjane4413]

It was designed before the war when Hitler was lavishing industry with (borrowed) money. That is why it is intricately designed and precision machined. It really was an exercise in "machinist pron". By 1944 however, Germany could not afford the time, cost, and precision machining as demand from the front and bombing of factories meant that they could never build enough.

[@mske903]

was the transmission of the Sherman or T-34 much more simplified?

[@obsidianjane4413]

​@@mske903 Much. Both found more practical solutions that had greater tolerances and lower part counts.

[@BenJamInn-q3o]

​@obsidianjane4413 what borrowed money genius??? I think fools like you should be legally required to do research.. Germanys was never once at any point during the greatest period it ever had under the man who countless times tired to avert abd stop war borrowed money... Germany operated on barter system something Roosevelt tried but failed which resulted in FDR starting WW2. GERMANY NEVER ONCE BORROWED MONEY... ALL THE MONEY THEY HAD WAS THEIRS

[@BenJamInn-q3o]

​@@mske903the anerican transmissions had tolerances so loose that you could stuff dishwasher between the mating surfaces.. Wanna see anerican "quality" look at the trucks and the welds... every US weld looks like a 4 year old made them and every piece has machining marks

[@k.-h.h.7670]

D.R.P. is not an abbreviation for the name of a manufacturer but is the abbreviation for "Deutsches Reichspatent", a German patent issued at times of the German Reich. Many thanks for your great work and best wishes from Germany.

[@shakesc]

Great to wake up to workshop Wednesday

[@Ekatjam]

My father was a machinist in Germany and received his accreditation shortly after the war. The state (East Germany) issued a passport-like book that showed how he performed and his qualifications. True to German standards, the last section is his grade on political matters. He still laughs that he was a highly qualified machinist, but a poor political one. Ironically, he would come to America and machined parts for the camera system on the U-2 spy plane.

[@naradaian]

What incredible workmanship whilst under mad bombing. Absolutely no compromise

[@BenJamInn-q3o]

And absolutely nothing in Hitlers Germany was ever built with "slave labor" as EVERY WORKER EVEN HEWS WERE PAID AND WELL FED

[@Th.G.M.]

I am fascinated watching this transmission chapter being worked on. What elaborate and finely machined parts could be fabricated back then about 80 years ago. Would love to see more!

[@babuzzard6470]

And under wartime conditions.

[@Epitome63]

Very interesting and amazing German engineering and precision.

[@VonRyansExpress-v3r]

What an incredible piece of engineering - fascinating to see it disassembled, looks to be in superb condition . . .

[@DavePocklington]

The amount of work and superb craftmanship of the German gear is astounding. No wonder they never churned out the numbers needed for the war effort. I remember reading an interview with a German mechanic who had been captured on the Eastern front. They made him work on Russian vehicles. He was amazed by the way Russians think when presented with a problem. They always went for the easiest and most simple solution. Without thought for future consequences. For instance he mentioned a case where they were asked to fit a small spotlight on the front of a truck, near the windscreen. Their solution to having to wire it up to the electrics was to crack the corner of the windscreen. No laminated glass in 1943 Russia. Then run the wire through the small hole to connect up to the wires in the dashboard. No thought was given to the minus 40 degree cold that would come through the hole straight at the driver.

[@mikeandhev]

Great presentation by everyone.

[@Ganiscol]

5:09 - As per the British Merchandise Act of 1887, imported (machine) goods needed to be labeled with the country of origin. This must have been some generic part that used to be exported to the UK as well before the war. So, either old stock or it was labeled as such because the drawing said it has to be labeled as such and they just kept doing it. 😅

[@vsvnrg3263]

that writing is in english for the same reason that germany never attacked sweden. sweden was a source of bearings for uk and the only source for germany. if germany had attacked sweden, sweden would have totally destroyed its bearing factories leaving germany with no source of bearings. uk could get bearings from usa.

[@Henning_S.]

​@@vsvnrg3263but Germany also had its own ball bearing factories...

[@vsvnrg3263]

DRP is not the manufacturer, it basically just means "Patented" (Deutsches Reichs Patent) The real manufacturer is probably ZF

[@frenchroast1355]

It still amazes me that so much engineering, tooling, and design goes into something that could be ruined in seconds by solid shot.

[@stephencox4224]

Hint when you want to clean sensitive parts with a glass bead blasting cabinet use sugar not glass beads because you will never have any potentially damaging glass beads hiding inside ready to wreak havoc. The reason you use sugar is it simply requires a hot wash to dissolve and remove the sugar wheras I have seen a nunber of engine components damaged due to improper cleaning after glass bead blasting. The only time I use glass beads in a gearbox is if they have brass synchro rings and glass bead blasting them brings them back to life allowing them to actually brake the required gears to enable a clean non graunchy gearchange without buying either expensive or unavailable synchro cones.

I've worked on a few ZF gearboxes from the 1960's for the Maserati Ghibli and Aston Martin DBS. I thought that those gears were huge...until tonight! Wow, auto mechanics are trembling at the site of the size of these gears. Your narration is excellent- that Stug gearbox is a work of art. Just the ally casting of the case halves- I would have loved to have seen the factory that made them. Hope your viewers appreciate just how physically demanding this job is- just the weight and size of everything! Torque values must be enormous on those shafts. Great work, thank you.
