Just the realisation that someone had to sit down and design this with a pencil and ruler, they had to work out the tolerances that were needed for it all to work, without a computer, without CAD, without a calculator, it just leaves me in awe.
This episode was absofrigginglutly great, I enjoyed every minute of it. One question I have just out of curiosity: Did you happen to get the weight of the assembled main shaft assembly. I'm kind of a nerd on little bits of information like that . These videos really make my day waiting on surgery in my neck . Have a great rest of the year and many more to come.
Do not forget the whole team was directed by the senior staff that is calculating with a pensil and the ubiquitous slide rules. All this is truly impressive when you think about this but it was the same since the industrial period until the arrival of the PC 🖥 computers. Again a great job you did guys 👍👍👍👍👍
I work for ZF in germany and came across this project, because someone asked for drawings of the transmission in an internal forum and its really cool to be part of the same company and see that after 80 years the transmission is still in good condition
My 1969 Aston Martin DBS has lovely ZF power steering and the 5 speed gearbox- same as the Maserati Ghibli. This Stug gearbox looks a bit larger, just a tiny bit! Love ZF products. Cheers
I know nothing about transmissions, but that was a transfixing 22 minutes. Hats off to Beau and Steve for their amazing knowledge and skill. Reassembling such a piece of history is truly mind-blowing. And, a special thanks to Kurt. I don't think he gets enough credit for documenting this so well.
Bearings are made to an international standard according to required tolerances and working requirements. So a bearing made then is still made today. Though some were designed for a very specific need which could be no longer produced.
The last few seconds of the video and the smiles on both faces really sum up this video. Another fantastic Wednesday addition. As always, thanks for sharing this with us.
Well done lads, what beautiful engineering, it still stuns me that they could make equipment like that so robust and to such fine tolerances in the middle of a dam war !! PS wonderful explanation of the parts and assembly 👍 PPS well filmed too Kurt
You say that, but a lot of the later stuff had some real issues with gearboxes & final drives. Towards the end, the available quality of metal drastically decreased.
One of the reasons that Germany suffered so much with AFV production was the insistence on quality engineering, that made replacement parts hard to source as the production line took priority and made repair in the field more harder. You could argue that the Soviet approach of a tank just good enough for the day made sense as the T-34 was turned out in numbers that made the production of the STuG look small.
After spending 37 plus years in machine shops, I have to admire the work they put into a vehicle that could possibly have a very short life span. All the hammer work involved reminds me of a saying we had....." Don't force it....use a bigger hammer".
I love the way you explain everything to us like we are kids. "This goes here and it does this,while this goes there and that does something else"....finaly someone that actualy describes stuff a way that everyone understands it. Sending love from slovakia
Wow! I can’t stop thinking about how this transmission began as a idea to paper to manufacturing to assembly to everything that happened to this transmission to today. Thank you for such another excellent video.
Being in a similar trade for many years, I’ve found that a countertop convection oven does the trick of heating up and expanding the bearings/gears enough to allow them to slide down with ease. Sometimes even saves the bearings and gears from minor damage as a results of trying to drive them on by hand. Still great work and I enjoy your channel!
When it comes to rebuilding jet engines, usually you have a large chest freezer you can chill the main shaft down in along with heating the bearings up before you assemble the whole stack.
My father just used the gas oven in the kitchen to do such things. To unhappiness of my mother. We had no other option. Works great. English: gas oven. Dutch: gasoven. This Etna oven is still on its spot since 1967 and in use.
You can not appreciate in this day and age how they managed to build something as good as that all those years ago , if you think about it things hasn’t moved on that much really apart from maybe f1 gearbox’s but general gearbox’s hasn’t , and great seeing you guys rebuilding it 👍
Il cambio dello Stug III è un vero gioiello di meccanica e pensare che è stato progettato quasi un secolo fa!!!. Bravissimi Steve e Beau nel rimontaggio. Episodio bellissimo.
16:43 guys, you insert it with the round part of the shaft to the spring, then use a slightly crooked pocket screw driver to rotate it to the latched position where the spring falls inside the pin's groove. This might be an early version or defect in the batch, but normally, these have a screw driver slot in the end of the pin, so you can rotate them once inserted into position. So compress the spring, you usually use a piece of flat stock, bent in a U shape. The two ends of the U shaped tool press on the flat of the spring.
I can’t wait for next week when you sync the other side. Just awesome. BEST SHOW ON UA-cam!!!! What’s amazing is somehow, someway , German Mechanics did all of this in the field under adverse weather and conditions, under fire , and under attack, hoping nobody fucks with the parts supply line.
These two guys are amazing, and a pleasure to watch...they do their work with such love and confidence, it is really nice to watch...thank you all for showing their amazing work, and the whole team either!!
As an ex mechanic from the uk .....its really satisfying qatch you guys bring some really heavy duty ....mechanics into bring these vehicles back to.life ......makes fitting clutches into fords look bloody easy ......loving the films ......
Beau and Steve working together on this gear box is pure joy. I could watch this all day long. Thank you, and please videos on all the steps in getting this box back together would be wonderful.
Simply stunning engineering. Steve and Beau are engineering wizards and I could watch and watch again and again. I would love to visit to see the action in the raw. Thanks Kirk for your wonderful workshop Wednesday videos. Cheers from the UK.
Love this show: like watching surgeons working on the intricacies of a living body. Their knowledge of mechanical theory is exceeded only by their several skill sets.
I hate you guys! I'm waiting the whole week for the new part of workshop wednesday, and you guys are, just gouging my eyes out with only 22 minutes of pure pleasure!!!! 😍 I love it!!!!!
To say Beau and Steve are members of a a very exclusive club is an understatement! How many people have completely rebuilt one of those transmissions 80 years? Give the Bard his credit for capturing the event, Kurt!
We’ll not really. Remember they knew nothing about these until they dismantled it and along with drawings and specifications it was an on the job learning process. Any competent fitter, anywhere in the world, could have done the same job.
I'm constantly amazed at the incredible skill of the designers, machinist and engineers who put in so much effort and resources to make such engineering masterpiece, all the while with bombs dropping day+night. All to carry some big gun around that at the late stage if the war, when this was made, probably lasted a few minutes in combat before being blown away. Seems an utter pointless waste of endeavour and resources, let alone lives. Beautiful work guys!
German engineering at its best, amazing to think that in 1943 with the massive demands of the eastern front, north Africa and Italy they were still creating these masterpieces with such precision and attention to detail.
Such a pleasant experience watching and listening to a bunch of Queenslanders doing great work on classic vehicles......Unlike the new Jaguar car and its mind numbing advert.
@@Gary-Seven-and-Isis-in-1968 a bit more than you I bet. You don’t know my work background and as what you said I’ll bet you have very limited engineering knowledge.
@@tridbant Dunno Grandad, you're trolling me here. I'm sure with your 113 subscribers you're bound to be better than these guys with their lousy 212,000 subscribers. Especially when it comes to fixing a Moped or two 🤡. Troll Harder.
@ hahahah what are you talking about. Cheeky bugger, never owned a moped in my life. Where on earth am I denigrating the tradesmen on the show. What I’m saying is, don’t imply that tradesmen and manufacturers were more competent then than they are today. Don’t denigrate the untold thousands of fitters around the world who could have, including me, have done the exact same job as they did. As for trolling correcting what people say is not trolling.
Anyone else be left with a big pile of “spare bits” after doing that? 😂😂😂 Or is that just me. How do you guys remember where it all goes and what connects to what? Amazing job a work of art. 👏👏👏
Amazing job, guys! What a difference cleaning all the parts makes. They look like they just came off the assembly line. 22 minutes goes by so fast. More please.
It's interesting to imagine the last person who worked on that engine when it was first assembled, and all that was going on at that moment in the world. And here you are now re-assembling it now, just as they/he did then. Little mind bending when you consider it.
When I was a young mech, I prided myself in knowing more about manual gearboxes than my peers. Thanks to Steve and Beau, I now know it was a good thing I didn't brag!!! Great stuff.
Well done. I dont know much about transmissions but it looks challenging to reassemble. And of course it clearly took a lot of smarts to design and build.
Amazing engineering feat and design considering the Germans didn't have CAD software, but only slide rules. Fantastic rebuild, enjoyed every moment of the transmissions assembly.
Truly good mechanics>>>just great to watch>>>Mech tip for tight fitting parts/ bearings heat them in oil lil over 120f and they will slip in ezer. Heat is the key to less hammer work :) A little heat goes along ways.
Not many of us get to see the inside of any gearbox let alone this monster. Great. Glad to see you liberally applying the hammer during the fit up. I was always concerned I might be doing damage!
Working on machines can be at times a frustrating thing to do but taking apart a 70 year old machine with jello lubricant and then cleaning and ramanning some of the parts then reassembling it is just flat out amazing as said before hats to Steve and Bo and as always thanks to Kurt for documanting these thing it's a full time job I'm sure.
that knowing smile they gave each other at the end! says it all really. It doesn't get much better than this boys, great work EVERYONE at aus armour. I'm sure there is a lot that goes on we don't see and people don't call out, but good god this is amazing stuff.
I've gotten use to you guys wacking away with hammers. But as an aircraft mechanic, it's the quality of the lockwire that made me cringe the most 😆 All jokes aside, you guy's are doing a fine job on this one.
Just the realisation that someone had to sit down and design this with a pencil and ruler, they had to work out the tolerances that were needed for it all to work, without a computer, without CAD, without a calculator, it just leaves me in awe.
More likely a whole team of designers/engineers
Madness really. Not to mention that it would have been manufactured (or at least finished to tolerance) by hand, not machines.

You wouldn't think you'd describe a gearbox as beautiful but it really is a thing of beauty made with the precision of a swiss watch
I was just going to comment the same thing. I have no idea how it would work but it really is a piece of engineering beauty.
Very precious metal

That transmission, what a work of mechanical art. And all the new bearings being still available. Magic!
And that's why they lost the war over engineering.
Bearings are made to an international standard according to required tolerances and working requirements. So a bearing made then is still made today. Though some were designed for a very specific need which could be no longer produced.
@@tridbant That said if there was a part that used weird, funky and non standard bearings it'd be a German or British tank.
@@hannahranga yes, I mentioned non standard ones.
Thanks Steve & Beau, that was a truly absorbing video, Cheers
Its amazing to think about how much work goes into putting 1 tank onto 1 battlefield for it to possibly just hit a mine and its all over.
price of people believing in populism and grandiose reality.
The last few seconds of the video and the smiles on both faces really sum up this video. Another fantastic Wednesday addition. As always, thanks for sharing this with us.

maybe even double down with those wine bottle ice packs over the main shaft
When it comes to rebuilding jet engines, usually you have a large chest freezer you can chill the main shaft down in along with heating the bearings up before you assemble the whole stack.
