This was awesome content Peter. Thanks to Total Innovation for letting you see behind the scenes as it's always a pleasure to see craftsman at work and their cool tools!
Just a random idea: You could make threads in two of the bolt holes on the cover so they would accept a slightly larger bolt for pushing it out. Before inserting the bolts, you would screw in two lock screws with a long hex tool to prevent any damage to the bolt threads on the housing.

This deepdive into what it takes to produce some of these one off parts are so interesting. How many doors that has been opened because of this technology must be too many to count. 3D printing and so forth has made you and I being able to make new parts for 1/100th of the prices just 20-30years ago. You had to be Jay Leno rich to restore certain cars. Wonder where this industry will be in 10-15 years?. God bless from your neighbor to the east Peter. Lots of love.
Jävlar vad snyggt det blev. Och j vad duktig du är. Så roligt att titta på dina videos, jag är lite dålig på engelska så lite svårt att hänga med i alla fackuttryck. Men jag lär mej.😊 Lycka till med allt och att det håller nu.
Volkswagen käfer has the same problem on the standard transaxle. For racing ive used sort of the same billet covers. Some guys used metal cages around the pinion covers. 😊
@PeterBjorck 22.20 its typical for 4x4 diffs. You install a bronze or other bushing material pad and tighten it just a but. but the bolts for it must be a big one or a set of bolts
Use a finer pitch brass for next gen- easier to adjust, might introduce one more and get them spaced around the pinion engagement point, if it flexes it would still flex "vertically".
The bronze bushing isn't a bad idea but maybe find something ball-tipped instead to reduce the possibility of shavings? The only other way I can see to reduce deflection is to have a "roller" pinion 180° from the input shaft - requiring a complete gearbox redesign.
Das Scannen des Originals führte aufgrund der seismischen und akustischen Aktivitäten der Umgebung zu zahlreichen Interferenzkorrelationsdaten, die zwar nicht zum ruhenden Werkstück gehören, jedoch bei der Nutzung des Werkstücks im Fahrzeug relevant sind. Die Umrechnung von Interferenzdaten der Werkstücklage während des Scannens in die Werkstücklage im Betrieb ist allerdings sehr komplex. Der Hard-Software-Interferenzwandlungsprozess würde erheblich erleichtert, wenn um den Werkstückträger, die Aluminiumsäule, symmetrisch drei Beschleunigungsaufnehmer mit einer Auflösung von 32 Bit positioniert würden. Um die Scan-Kamera optimal an die seismische Neutralisierung anzupassen, ist es notwendig, die Messsäule zuvor mit Planckmasse quantisert von, einer Werkstoff-Referenzmasse des zu scannenden Objekts zu belasten, um damit die Kamera zu kalibrieren. Eine longitudinal neutralisierte Kamera, die mit drei Lasermikrofonen von mindestens Sennheiser-Qualität ausgestattet ist, um das aktuelle Umgebungs-Schallfeld zu neutralisieren, kann durch die Erfassung des UV-Licht-Wärmeeintrages in den Werkstoff über den Infrarotmesskanal des Scanners die maximal mögliche optische Goldionen-Grün-Abbildungs-Präzision erzielen. Das Werkstück wurde mit einer großen, bearbeitungsbedingten Oberfläche hergestellt. Da der Werkstoff dazu neigt, elementaren Wasserstoff H1 einzulagern, was die Festigkeit stark reduziert, wäre eine Hochdruck-Tieftemperatur-adiabatisch entmagnetisierte Wasserstoffextraktionshärtung in einer flüssigen, werkstoffisotopalen Edelgasmischung vermutlich die beste Methode. Anschließend lässt sich das Material in DOD 20 Wasser mit einer superperfekten Eloxalschicht versehen, um es erneut vor dem Eindringen von elementarem Wasserstoff zu schützen. Das präzise einstellbare Notgleitlager am Lastzentralpunkt des Tellerrades wies keine ungewöhnlichen Belastungsspuren auf. ¥€$ Gute Arbeit Herr Bjorck, Gruß Reiner Markenfreund £équi$€¥ Michael Frithjof Müller
Pretty cool. I'm guessing back in the old days they would have just made the the cover thicker? It would be fun to see how a greybeard would manually pick up the critical dimensions and produce a part on a Bridgeport.
Winters diff has a brass adjustable plug that rides on the back side of the ring gear that eliminates flexing you need to copy that to keep the pinion from flexing still going to flex thew the baring to much leverage
I mean, this all seems to be assuming the cause of failure was mechanical. This is certainly an upgrade in strength, but my concern is that ring and pinion failures often have a lot to do with oil starvation, cavitation, and the resulting heat weakening the material. I'm not necessarily saying that IS what's happening here, and higher strength holding things in place better will certainly improve load handling either way, but if you want a diff to be bulletproof, it's definitely a good idea to make sure your oil is staying in good condition and getting where it needs to. Also, it looks like you might have spaced those bearing landings apart a bit more in the redesign? Excellent choice if so. Don't know the application, and that often wouldn't be possible, but if it was and you did, that'll definitely help keep things in line better.
Hi Peter. Do you have any suggestions for an affordable 3D scanner to be able to 3D print various items? Also, did you add the runout measurement on the pinion? That would help you visualize the more exact location of input stress location.

Hey peter this is beautiful work from your friend Christian with the addition of your bronze flex button of course, how long did it take for the part to be made start to finish
Damn, that janky looking measuring arm is almost NASA level accurate, tolerances for each individual axis must be way less than ± 5 microns. That's about ± 0.2 thou in freedom units.
Heloo Peter. I have one idee. The 850r come back. And i have 850 tdi with original lether and have a oriniginal whood of panel . My idee have a little . From sweeden. My car tooday v70r.

Wow that cnc machine is awesome.
World would be a better place if there were more people like Peter. I wish you the best in whatever you are up to Peter.
Takk for den beste underholdningen på youtube, Peter!
Very nice to be able to see the entire process. Cheers
I really do like this kind of content thanks for sharing it with us 👍
Very good CNC machine work, kudos for the workpiece! Thanks for the video Peter and go on with more!
As always, impressive work Peter and Total Innovation

I thought the same thing. Jack bolts would be nice instead of slots for caveman style prying on such a beautiful and functional work of art.
This is artwork! Beautiful.
Love this show
Simply counterbore the bolt which catches it won’t weaken the casing in any way.

Tack för den bästaunderhållningen på youtube💯, Peter!
Super interesting video. For someone that has no clue how any of this is done it’s nice to watch.
Always something to learn with you, Peter. Thank you, fascinating process and very clever machines and people to make them sing.

Great content as allways! Fun to see Christian also, friends from childhood building togehter 👍🏻 Östansjö FTW
Grym video som alltid!
Very well innovated Peter. Lovely too see how you make use of hightech to improve your car! 😊
Nice video Peter! I do a lot of stuff like this. Love that machine.
Always quality content from this channel. Thumbs up
Great video. Thanks to all involved.
Super intresting!!! Total innovation guy was really professional !
Well done!! Absolutely love watching your videos keep up the great work much love from Canada
Awesome idea and execution from TI. Thanks for sharing 👍
Hi PeterBjork. you can Drill two opposite Release Screws to the Flange or just Threaded Holes, to the Diff. Cover.

Good one. even Pretty. Keep it warm. Thanks for the Study.
Siemens 840D is my favorite system :-)
That turned out really really nice. 🤩
Put 2 or 3 equally spaced m8 threaded bolt holes between the diff cover fixture bolts, you can then wind in some bolts to jack the cover off 👍
Jösses vilket maskineri👌Man blir tagen av vilken utveckling 😳😂👍Tack för film.
On competition land rovers they weld a block on the diff housing to bolt a large bronze slipper to support the crownwheel.
Amazing work of Total Innovation & you Peter =)
the power skill hand and mind...good job bro...coming to drag thailand 1 day bro...
Hexagon, Leica Geosystems is a Hexagon company. They have always innovated before their time. It's good see they're still going.
@PeterBjorck 22.20 its typical for 4x4 diffs.
You install a bronze or other bushing material pad and tighten it just a but.
but the bolts for it must be a big one or a set of bolts
thanks for showing the workflow 🙏
First time I caught a fresh video!
Great to see you moving ahead with the project should be a lot stronger next season 😀
I noticed the Holinger X12 sequential shift transmissions use a 300mm/12" diameter ring gear!
same issue with the 90 degree gearing inside Opel Calibra transfer box, stronger lid helps it hold togeher.
Engineering skills +
Wow, wow, WoW. Call it the WoW signal LOL.
What a fascinating vid. Like Project Binky but without the 3 year wait between episodes.
Use a finer pitch brass for next gen- easier to adjust, might introduce one more and get them spaced around the pinion engagement point, if it flexes it would still flex "vertically".
Very interesting, thanks Mr Bjorck
That crown wheel is SPECTACULARLY broken!
The bronze bushing isn't a bad idea but maybe find something ball-tipped instead to reduce the possibility of shavings? The only other way I can see to reduce deflection is to have a "roller" pinion 180° from the input shaft - requiring a complete gearbox redesign.
Wow so interesting, thank you for sharing this modern technology.
Nice design! Hopefully now the gearbox casing doesn't become the weakest link.

It looks beautiful. I wonder if/when 3d printing in metal will be good enough (cheap enough?) to be a better process than milling.
Love Spinner machines 😍
Realy cool machine👌
Speed nerds. Love it
very cool that laser painting 3d modeling.
Loved this, thanks!
Really nice video! I enjoyed it very much 😻
Pretty cool. I'm guessing back in the old days they would have just made the the cover thicker? It would be fun to see how a greybeard would manually pick up the critical dimensions and produce a part on a Bridgeport.
Probably drill a hole in centre first and then work from there, all those measurements are on the original to copy apart from the added thickness
Good work, I thought you would have use larger bearings in the new design, definitely going to be stronger either way
Winters diff has a brass adjustable plug that rides on the back side of the ring gear that eliminates flexing you need to copy that to keep the pinion from flexing still going to flex thew the baring to much leverage
It looks like enough material to sink the bolts in with a bit shorter heads so all bolts thr same and clear the exhaust system
you can get short head capscrews to clear the exhaust.
Takk, interessant å se 👍
Bra jobbat
i look out for the next video 😎
That's a conical group of gears (ring & pinion) providing axle ratio... not a diff.
That wavetrack is the differential
You might want to speak to Dobson, or Rick @reperformance about that diff cover-up looks like the sort of thing they're interested in.
Good call vogs

These guys must have a huge cnc machine.
They swedish vikings.. If they dont have they build😂
Think haw much fun you could have with cnc.

Peter - are you going to do any more desert racing hill climbs?

What was the % increase in stiffness with the new design. My apologies if I missed it in the video.
Love it👍😎

Hoppas allt är väl, Peter!
Nice,, 👍🌟👍

Snyggt Peter! Men när du ändå är igång kanske ett större lager kunde vara nått o fundera på om det är i lagret som deformeringen sker?
Them machine marks are like carbon fibre to me, i love looking at it until you lose focus 😂
Damn, that janky looking measuring arm is almost NASA level accurate, tolerances for each individual axis must be way less than ± 5 microns. That's about ± 0.2 thou in freedom units.
Superb. 6 second car next year?
is that original casting full of voids or inclusions because it looks like it?
Heloo Peter. I have one idee. The 850r come back. And i have 850 tdi with original lether and have a oriniginal whood of panel . My idee have a little . From sweeden. My car tooday v70r.
Lagerbrons = Bearing bronze in English. (Bor i England sedan länge, och är "hobby svarv-/fräs-operatör".
Maybe drill a hole in the bronze screw and press a round steel ball in it to prevent bronze shaving in the diff oil.
Crazy how everyone is English fluent in Sweden
👌👍👍👍👍👍👍👍
Ser ut att vara dyra grejer 😀
😍
The bolt that you grind down for the exhaust why not cunter sink that hole so the heead of the bolt have clearance fkr the exhaust
Excited @ 18:21? 😂
Nu vet jag att jag blivit gubbe 😂😂👍
