Ask your questions about the diff or the StuG III G project in general, HERE⬇⬇⬇ we'll answer as many as we can in 60 seconds tomorrow 😁
so is the diff useable or not? i just find it crazy that this Stug and it's mechanical parts are in the condition they are. testament to the engineers' skill, even if this vehicle served on the wrong side of history.
Are shimes and bearings easy to purchase ( new parts?)
These guys are amazing..
Would be a absolute privilege to work on this project
How will you determine fastener torque values for re-assembly? Do you have a factory manual?
How many snaps do you take to document the disassembly? Just the diff has so many parts that must be sequenced. Baggies of parts and memory are obviously not enough to reassemble.
Watching the gearbox & differential disassembly has given me a new-found respect for these old vehicles. They are truly works of art.
*Exceptional German engineering.*
I love seeing the marriage of design and manufacturing limitations and factors into 1 unbelievably compact package. Noone could do this without a computer anymore.
Overcomplicated German Engineering
@@demonicsquid7217
Normally youd be right
But part ot the reason why the stug was so effective is because its design was really working with an "absolutly neccisary only" basis
Yes, but did you notice it had broken internals because it wasn't assembled correctly? And the voids and weld patches in the castings are a clear sign of desperation, a manufacturer with better resources would have surely scrapped the part. So it's very possible this transmission assembly survived because it was a lemon from the start.
I find videos like these almost therapeutical, no nonsense bravado, no over the top statements, just plain competence and nice work.
Clickbaity title is in stark contrast to the video. Absolutely unnecessary imo.
Its the Aussie way
What reality tv should have been!
Exactly. Highly skilled, nice dudes. No bs. Just came across this channel and I already love it.
It’s the parking brakes. One lever, both drums. Locked.
And of all the mechanical restoration channels I watch, this one is the most impressive!
Lots of people can take complete vehicles and make them run…only this one builds them out of individual chunks dug out of the ground! LOVE you guys!
And here I was guessing that it locks the differential. 😅
@@Arachnikadiayou're right, it is the differential lock brake.
It's so nice to hear Aluminium! Australia, hip hip hooray! 🇦🇺🇦🇺🇦🇺
You'd have better luck with "Aussie! Aussie! Aussie!" (:
@@ConstantlyDamaged woooosh ... the sound of the point passing over your mind.
@@BTW... Aww, mate, you must be a little confused there. Let me explain it for ya.
In Australia, a common chant-reply is "Aussie Aussie Aussie" which is replied to with "Oi Oi Oi". My comment was merely asserting that "hip hip hooray" would be better replaced with this.
As for aluminum vs aluminium-I have no real opinion. They were both discovered and established in two different parts of the English-speaking world at roughly the same time. They're both valid and correct.
@@ConstantlyDamaged .LOL, and ya still missing the point in a six word comment.
Hint for the slow ones... key word is "hear".
Born and raised in Sydney, lived in 5 States, now Melbourne VIC - I full well know the mindless chant of sport crowds. Worse when from yobbos on the piss and it goes on and on. Worse still.. out of ultra-Nat bigots, based on a "better" lie.
There is no "better" or "luck" about it.
Be damned I want to hear that basal chant.
Jingoistic? Yeah... but no. Thats an exclusively American title. They have an equivalent chant, bellowed by the boorish and thug type... "USA, USA, USA".
I'm sitting here holding my breath, never thought I'd see a ZF SSG 76 with the diff taken down. It was absolutely the right decision to take apart, as the bearing and track ring clearly prove. Nice work and a big thank you.
Sure they could. It would just take some trial and error. Heavy equipment is still not much different from this type of stuff
@@roachwerks3043 what do you mean?
The complexity and tolerances of these machines are a work of art. The boys are so lucky to have the chance to restore and bring life back into these past beasts of war. Great work boys, looking forward to the next instalment next week.
Steve has been such a great addition to the team.
My dad used to set up differential ring/pinion by feeding a strip of paper between the gears. This showed the tooth contact pattern and the backlash. If it cut the paper; too tight. If the pattern was not well defined; too loose. Only then would he verify with a dial indicator. He never had a failure. During WWII, he was part of a team that figured out why troops were being killed when the brakes of their 1-1/2 ton trucks locked up going down hill. He figured out that the exhaust was run too close to the brake 'booster.' Rerouting the exhaust solved this. He passed in the early 90s, but I can say with certainty that he would have loved working with this team.
It’s heartening to see that the ubiquitous and humble screwdriver is still the mechanic’s tool of choice for prying, punching, scraping, and wedging. I love to watch these guys work.
If I had ever been seen using a screwdriver thusly...
So I bought a set of punches and a set of prybars.
And razor-thin putty knives. Jesus! First do no harm!
Your courage in pulling this apart is commendable! It would scare me sh*tless!
yes , it would , but putting it back in working order .......Argggg !!
in case you hadnt noticed they have copious camera recordings of the dismantling, thank goodness.
@@vsvnrg3263 there is reassembling and then there is the spacing and tolerances
I've wept bitter tears learning about that
@@vsvnrg3263 Sry mate, I was doing some file transfer, but I accidentally deleted all recordings permanently.
I'd already be working on excuses for why, after reassembly, it appears to have become a single speed with a permanent diff lock and no neutral or reverse.
No piece of metal has enough power to go against the incredible folks from aus armour! I love your work!
All the best from Germany 🇩🇪
Sascha
Love watching these guys work...real joy..
These videos are a world class lesson in how calm, educated minds can come together to solve very complicated problems. The world should pay attention.
Bo’s knowledge and talents in engineering are some of the best ive ever seen. And that mechanic working with him is one hell of a mechanic. Definitely got one of the best teams around on this job. I hate changing drum breaks but they do last a long time.
I was a jet engine mechanic in the Air Force back in the 70s 80s 90s, we had to safety wire just about every bolt on a jet engine. What really impressed me was the safety wire on the bolts.
Some mechanic safety wired those bolts something like 85 years ago. I can imagine him doing that in my mind.
Yes I worked on JT8Ds
I just love Workshop Wednesday, and today's episode was just amazing. I had to stop the video a couple times to wipe dribble and take a breath, I was transfixed. Thank you, Beau & Steve, you both deserve a Lamington at morning tea, or even better a Bee Sting with warm custard. Cheers
No computers or CNC machines when these gearboxes were built. Just beautiful craftsmanship from highly skilled machinists. Just amazing the amount of detail and high quality work. 👍👍👍👍
Beautiful engineering.
I have changed my designation of Wednesday from hump day to workshop day.
Just fantastic work love the skills shown and the ingenuity to overcome issues.
why
im allso very tierd so i probaly miss read it
Just watching this episode made my arthritis kick into overdrive. Getting old is not for sissies , these videos are the only thing during the week that get me by.
Well done, mates. Beau, that is a great removal tool. The Germans loved their planetary gear systems. Great video work.
That was so satisfying to watch and a pleasure to see such a good job well done! Once again I am so happy you decided to inspect and restore that amazing piece of engineering . Thanks guys
What an amazing puzzle to get apart, now to clean it, and then the most challenging part, remembering how it all goes back together!
That’s what blows my mind….
The complexity of the German equipment is mind boggling. It had to be so detrimental in the field. Keep up the fantastic videos!
Es increíble el grado de ingeniería de de esa transmisión de más de 80 años la perfección alemana no se compara increíble trabajo que hacen de restauración excelente 👍👍
EPIC, thanks to all involved!!
Much respect for the skills and experience displayed here when the guys, on encountering a stubborn component, know when it just needs more heat and a bigger hammer, and when it requires a rethink (because there's a hidden circlip or a nut on the back side). So easy to get it wrong and stuff up an otherwise pristine mechanism.
Fascinating to see how these complicated elements work 😁👌👌👌
What am I absolutely mesmerized by watching these bolts? Maybe the history? Maybe as a human, watching 80 yr old bolts give way to these magicians of restorations.
Who last saw all this? Likely under incredible stress. Wow, history!
Thank you, guys.
Thanks for a another great WW. Beau, Steve & Kurt are StuG lifers ✊
*WOW! This was so mesmerizing to watch. Can't wait for the next episode to see all those parts cleaned. :)*
Merci pour cette belle histoire et ces belles images !
The president of my IPMS (International Plastic Modelers Society) mentioned your YT channel in the last newsletter, mentioning what a discovery it is.
I agree totally. You are a joy to watch, especially seeing all of the talent involved....
The joke about the Daryl tool was on point 🤣
Real restoration ,nice to Look.👍
Unbelievable, how much precision and effort went into the machines, that might have survived just days or hours after having been delivered to the frontlines
The transmission and differential - pure engineering and mechanical masterpieces. So fascinating to watch and try to comprehend.
I knew when I heard that wonderful jingle that my AUS amour fix was coming to end. Another job well done you boys down under. Bravo.
Thank you for videoing these so that we may be able to see them. Such a fascinating time to live in, when we see folks restore old machines halfway around the world. Great history. Thank you.
Amazing engineering. I am an engineer myself. I just marvel at the complexity and quality of the engineering. And this was done 80 years ago. And seeing the tanks being blown up by the hundreds these days in the Ukraine makes me realize how incredibly hard it is to get a good tank to the front make them work exceptionally well and still knowing they are shot to pieces…in the end.
It was great to follow your work, very interesting, to have a look at the workmanship!❤
I echo all the comments about the mechanical wizardry showcased within this gear box and the tremendous capabilities of the crew turning wrenches in the disassembly process. That said, I have to compliment the cameraman and video crew that allows me, 1/2 world away to follow this restoration in painstaking detail. The camera angles and being at the right place at the right time is exceptional. I’ve always dreamed of visiting Australia…….if I make it there, Aus Armor and Artillery is on the very top of the must see list. Thanks gentleman!!!
Nice Job guys!
I find this so mind absorbing watching you guys take this old machinery apart. Working on a farm in my youth with my dad he very often had machinery apart, this takes me right back to those times. 😊
The engineering and close tolerances on this differential is nearly just as mind boggling as the gearbox last week! I have a new appreciation for the Stug.
Bloody awesome you blokes, I can’t get enough of you working on the various projects that you have!! Best wishes from Tasmania
how well these tanks are engineered. amazes me all the time again.
Fantastic camera work
You guys are awesome. This is going to sound weird, but it makes me happy to know there are people in the world working at this level to restore old mechanical things.
Awesome guys, looks good inside apart from the cracked bearing 👍👍😁
When it’s all said and done, these are some real works of precision engineering, their boys weren’t going onto the battlefield in anything less than magnificent machines. It’s so sad that all that engineering couldn’t have been put to a more humane application. Truly amazing
Unbelievable work,good on you guys
I'm guessing those smaller inboard brake hubs maybe the park brake
Thanks for sharing
Since 1993 I’ve restored over 25 vintage Military Vehicles and I never went into armored vehicles, just too much required to properly restore them as we’ve seen in these videos. The toughest I had was an old Mighty Mite.
Blimey! It looked like it took every toy in the box for that strip down. Great work guys! What a piece of engineering. 👍
So complex!! What engineering.
My goodness these are complicated, involved, superbly designed and constructed parts!
I love the Daryl socket, with the lost tooth. That was obviously an off the cuff remark, that hit home straight away! I wish I was able to be there to aid these guys with the stripdown. It looks like a 3d puzzle that I would enjoy! Thanks for some really good shots of the disassembly, keep up the good work and see you next time for more of what I love. From UK.
I absolutely love the StuG III series! fascinating tech excavation!
Very interesting video Kurt and thank you for sharing. Well done to Beau and Steve on this complex overhaul of history. German ingenuity and quality showing through its 80 odd years of survival in this case.
Thanks guys love your informative workshop videos
Great to see Bo using the slide hammer to pull the bearing out. Great work and good video guys.
Fricken brilliant fellas. 🙂
The stick welded patches on the case look amazingly well done! The whole thing is really amazing,,Keep Crackin' boys! Love,,,Dubs
Steve looks so small next to Bo! I can't imagine what the insides of one of these on a T-34 looks like. Probably cotter pins, bacon grease and pot metal ball bearings! Fantastic work here by the team. As per the usual, I can't wait for the next Workshop Wensdaaaaaaaaaaaaaaaaay!
I realize the team has experience with the mechanics of these vehicles however it amazing to me the complexity of this gearbox and differential. regardless of the video documentation putting these components back together is a monumental task. I love this channel and hats off to the team of craftsman that work at the museum !
I hope you guys enjoy your work, because you do a fantastic job. The complexity of this, and other parts of the drivetrain for these old vehicles, is just amazing. As a hobby modeller, I build mainly German vehicles from WW2, and I appreciate the fact that these videos are just not fun to watch, but are very informative as well. Keep up the good work guys, and we look forward to the next episode of Stug Life!
WOW What a great job it is so interesting to see the parts coming apart and see all the heavy bearing and gears. Great job good luck with cleaning all the parts 👍👍👍👍👌👌👌👌👌
The boys are mechanical artists & magicians & it's a pleasure to watch them work their magic restoring vehicles.
Nice work, will be interesting to see it go back together...
I love what you guys do. The engineering that went behind making all this is outstanding. But what comes to my mind is what the jews,russians and many other prisoners went through to put all that together. How many died to make sure hitler had that transmission to be put into his war machines. How many dead hands those parts went through before final assembly. Honor those who were forced to make what you guys are taking apart and reassembling to bring back to life. We shall never forget.
Interesting to watch. And thanks for the video
As always, great job. Love watching the work that it takes to get these parts apart and back together again and just marvel at the engineering to put them together in the first place.
Ein Wunderwerk 👍👍👍
Why am i so entertained by this? ☺
Good interesting video. Steve and Bo are a good team. Thanks Kurt
I really love Aussie Workshop Wednesday and enjoy the narration and videos of all restoration!
The engineering on these parts is astounding! we are looking at wartime production, yet still it is all beautifully crafted.
Great work, thanks for sharing your adventures 👍💨💨
You know these guys love their job,they got the full financial backing to get any tool they want and a good shop,and to get to restore historical vehicles and getting paid to do it,unbelievable job :)
This is fascinating. I was happy just rebuilding a TH400.😀Level of complexity and machining detail here is amazing.
Great video, really interesting! Those two bakes operated by a single lever are a parking brake.👍
Outstanding video and presentation.
Love this channel❤❤❤
engineering at its finest ,amazing achievement for its time.
Good job!
Simply Amazing !!!
it's difficult to comprehend. The design process, no cad. the machining no cnc. and made in vast numbers.
They may not have had CAD/CAM, but you better believe they were standing on the shoulders of Joseph Whitworth. Metrology was a strong point of German engineering.
I was watching a prog last night on the Forth Bridge. No cad just logs and a slide rule. Then I thought of the Spitfire, Concorde, E type jag and all the other engineering beauties that never saw a computer. Just someone with a pencil!
Of course about 20% of the WWII labor force was made up of forced labor from Jews, other Eastern Europeans, including children. When Jewish forced laborers could no longer work they were sent to extermination camps. So people died to make this transmission and diff.
Yeah, ALL done with Slide Rules and highly skilled Turners and Millers. Bloody awesome !
@@GilbertdeClare0704 easy to see how such skills are lost with new technologies. keeping these tanks alive, passes on some degree of that knowledge. The clutch on this beast for a example. same as they use on automatic scooters. wow, not using plated.
Loved this episode. Great mechanics! Salute !
A fascinating watch as usual. Thanks guys.
Amazing German engineering,from 80 years ago. How can a nation so advanced in the world, building at such high levels. Loose the war against it! Thank you for all your efforts!
How many patents are in the works for Beau's tools? "The Daryl. Missing a tooth." Coffee nearly came out of my nose!
I was thinking the same thing!
Excellent work, as always. Many thanks for your Great Job !!!
Unbelievable complexity
Watching these two work like a well oiled machine is amazing.
Just brilliant work.
Amazing engineering that went into those vehicles. No wonder that they had trouble producing as many as they wanted to.
All this time I am watching this channel with a book on my shelf going unnoticed. I look at it and its Sturmgeschütz & its Variants by Walter J. Spielberger. I had no idea on the details...for those interested.
