Nicely done. I had to repair a gearbox that was used at Heathrow Airport which was used to jack up the nose wheel on 747s so the tyres could be changed. That box had lost all it's oil and was not checked until it seized. The TIG welding on the bearing diameter was a good move. 👍
Another great addition to the series Donn and brilliant repair and rebuilding up the bearing Cup as welding on alloy cast is inherently difficult with oil contamination. Keep up the great work
@@BIGSMOKE-bl2lq In one of Donns videos he mentions the displacement factor. I dont remember and dont care to look it up, but I was surprised at the weight that can be buoyed to hull volume ratio. To be fair, I highly doubt that a handsome bit of beefing this vehicle will sink it down more than is even perceivable.
@@levidbateman5174 It definitely appears that some reinforcement could be added in the area of those cracks that Donn welded up which appear to be inherent weak spots.
That is looking really way better than what you started out with. The oil changes and the magnet in the drain plug will be a good addition for sure. 👍💪✌
Great work me son !! My 6x and my buddies 8x pretty much had almost every weld cracked,along with cracking in solid flat areas also,every single stub shafts bearing was toast,every sprocket,every link of every chain,zero brakes remaining,tubs had multiple cracks,both engines smoked,tires were mix n match and mostly half would be flat the following day after airing them up even though they had very little tread left,were dry cracked all over,1 of mine was even splitting along the 2 casings joint.. Marks 8x was in much better shape than my 6x but his cost him 25% more for us to rebuild than mine did and neither of them were cheap to do a full off rebuild like you've done here and yes every single gearbox I've ever seen or worked on was thrashed like yours was... People literally believe these things are military grade tanks when, in fact, they're fairly light duty machines that actually do require a fair amount of maintenance and effort by their owners/operators.. I bought my 6x for $800 USD cash many moons ago and had not quite a new Argos cost in it when I finished,but it wasn't a while lot less,and Marks was the same way... Luckily a lot of these parts are now internet sourcible and readily available and cheaper than they were back then when one had to order out of a catalog,send in full payment,wait several long weeks for parts to be shipped,and then up to a couple of weeks for them to arrive... You're doing wonderfully Donn,keep up the excellent effort, and I'll sit back with a frosty adult beverage n relax while you do all the sweating and hard work 😅
Am amazing that this Argo stayed together as long as it did considering all the structural damage that you have repaired in this rebuild. It must have been beat like a red-headed step child from day one.
Reinforcement of the frame will be a good idea. I am worried about the distance between the frame and the pulley. There will be a torque and crack the frame again.
Bad engeneering on the sheet metal "frame", which holds the gearbox.. Thats obviously a stress point, where the crack started.. Can you weld a second layer over? A piece of flat stock or sheet metal...as a "bridge"...
Came here to ask similar - it's either bad design or abuse, but likely bad design. So some form of support around those brackets might be in order? Armchair engineer here! 😁
Hello, when you apply the sealant, as there is no groove, you could have spread it by tapping with your fingers all over the surface for a better seal. Thx you and take care ❤
Looks like those cracks in the gearbox support frame are a design flaw that may reoccur. Maybe adding strengthening plates at those corners could help (or just move any news cracks to another location 😞). Great video, as always. Stay safe out there.
I'm surprised that a man of your skills didn't just build a new gearbox mount with heavier material to avoid the obvious weakness in it's original design. Keep up the amazing work.
I'm in a time crunch with this one - can't spend time re-engineering things I'm not too familiar with (have to consider space constraints in the tub and so on).
As a couple of other people have already commented, that gearbox mounting frame needs to be beefed up to ovoid the same problem happening again in the future. Great work just the same.
Certainly looks like those cracked areas could be reinforced on the inside of that subframe but don’t forget Donn did say this thing was severely abused. Of course that’s just one way to find weak points.
Good work TIGing on that crap aluminum casting. I feel thats one of the hardest welding jobs to do. Casted aluminum is nasty/dirty stuff. Looks like at the very start you weren't hot enough and you got the typical response...filler rod balls up and almost repels the work piece. Next time, unless you're worried about that old bearing, heat it up with a torch before you strike an arc. You'll be amazed at how much easier it is to get the puddle formed and go to work.
Amazing repair work I was hoping to see some stiffening and braces added to the interior frame but you are the with eyes all over it, hope it all works out well
Good work, thats a cool gearbox, not so easy to find a (cheap) replacement one I guess! Your repair will probably work just fine if you keep oil inside the gearbox and not have it go outside😊
Cool project. It is hard to tell what chemical you used to clean the frame before welding but be careful if you are using brake cleaner, read up on phosgene gas, very little brake cleaner plus welding can mean death.
Now that you have the transmission mounted to it's frame, figure out were you can add reinforcement to the frame work to strengthen the mount for the transmission, your going to need to add reinforcement to other places as well, like the main frame.
Yes, absolutely. But I'll have to mount everything and check the clearances first. Otherwise I'll just have to hack everything off again if there are issues to be found.
When did you first realize you are a genius? Was it hard to not look down on your fellow classmates? Thanks for sharing this rebuild, very interesting.
Rich Rebuilds is building an electric one of those, I messaged him to throw away that gearbox and use two electric motors with a joy stick controller. But na. I hated the early gearboxes, they were rough and noisy. The later ones have a gradual turning system, far better.
"I rebuilt it as best as I could" would a 'professional' have done it any different? genuinely don't know, to me it looks like a fully professionally rebuilt item that couldn't have been done any better. even the welding
i don't think anyone notice but when he showed the bearing, spearing, and the little nut that keep the gearbox in place he but tremendous amount of locktight .
half of this work needs to be done immediately after purchase, than the designer thought to leave sharp corners next to the hole on such a loaded part ...

OK, fair to say this thing was built too lightly in the first place - add more steel! 😁
Definitely needs a few braces and stiffening in places all over
Add more steel so it sinks in the water

@@BIGSMOKE-bl2lq this thing will haul lots of people a bit more steel is not going too make it sink ,,
As best you could?! I think you built it better than it was factory! Cool unit, the way they made that frame definitely leaves a lot to be desired.
Donn you do good work , your a gifted technician

Man I tell ya. Transmissions are far beyond my paygrade. I am just not good enough. So great job man.
Great job. Do you feel like the cracked areas could have used some reinforcement?
Reinforcement of the frame will be a good idea. I am worried about the distance between the frame and the pulley. There will be a torque and crack the frame again.
I think I might have reinforced the cracks, but my welding is a deal less practiced. Besides, if it does give grief, guess who fixes it!
Gearbox rebuild looks good to me should last a long time keep it up
Excellent work 👍👍👍. Thank you for sharing. Be safe 🇨🇦
I could watch you repair and build stuff all day💪
Интересный способ востовления посадочного место под подшипник. Я думал что с нало варить потом просачивается будет. А тут раз баз и готово. 👍
Awesome job on the trans Donn great skills welding and mechanical 😮
Rolling along gracefully Donn, looking good so far. Thanks for sharing with us. Stay safe and continue having fun around there. Fred.
This gearbox is very interesting, very compact! It is gearbox+differential+break!!!
Yes, exactly.
Super wie immer
Your work Is the best, a lot of strength and congratulations.
Damn! when do you sleep! Thanks for sharing.
You did a great , welding around an old bearing to build up the casing , excellent ! The steel mounting is to light , needs a beef up . Cheers
I agree with add more steel especially around the gearbox frame where you can fit it without interference
Cheers from Aus
It's really very interesting to see how this funny vehicle is designed 🤩👍

Hello, when you apply the sealant, as there is no groove, you could have spread it by tapping with your fingers all over the surface for a better seal.

Great entertainment as always
It's looking good, glad to see that you're back!
Such a good series

Totally agree, there seemed to be plenty of space in the crack areas where a stiffening plate could have been a useful addition.
@@rl3898 Check out the next video in the series.
What gearbox is it?
it will be good great work as always and English is spot on
Hello u could make another plate for support (reinforce) gearbox and weld it on where was cracked, u have still space for it.
Well done and thank you for sharing! 😀
Hi Donn,
Your work is awesome, your attention to detail impeccable.
Take care.

The frame connecting gearbox and engine looked really flimsy. I wonder where it would make sense to add reinforcements?
Certainly looks like those cracked areas could be reinforced on the inside of that subframe but don’t forget Donn did say this thing was severely abused.
Of course that’s just one way to find weak points.
@@Crewsy Yes, and as others have pointed out, weight is more of a factor than in most of his other builds.
Based on the cracks, I'd put the reinforcement between the gearbox and the wheel axles. I.e. the chain pulls a lot harder than the CVT.
Awesome,i learn everythink ,thank you so much 👍👍👍👍
What a greAt video. You make it look so easy
brilliant, great to watch.

Epic re-man, man!
Nice work and great video. 👍
great work, and yea I enjoy watching your welding, very nice..... :)
Good job Donn
Seus trabalhos são ótimos parabéns
Top job number one
MM77 Approved 👍🏼👍🏼
Nice work as always 👏👏
The ol' allen wrench cheater bar is guaranteed to give at least an extra Abom™
I am surprised you didn't reinforce the motor/trans mount where it cracked. 😟
Love your videos, Donn!! ❤

Nice
I like it alot!
Nice job man. Some of these things it looks like you have done them 1000x before : - )
TIG WELDING!!! 😁😁😁MORE!!!!!!!😄😄😄
If there is a space, it will be good to reinforce the frame where it was cracked.
That TransSteel 2200 obviously didn't do the aluminum welding so did you get a new/additional TIG?
Love it keep it up as always 💘
Made in Canada 🇨🇦 👍👍
Cool project. It is hard to tell what chemical you used to clean the frame before welding but be careful if you are using brake cleaner, read up on phosgene gas, very little brake cleaner plus welding can mean death.

Super!
I keep waiting for each video to watch I really like your service you should just post faster
Looking good. What size wire and gas mixtures you use on mig welding?
1mm wire + Argon mix gas
As always 👍👍👍👍

I’m surprised you didn’t CNC plasma cut a brand new mount.
"I rebuilt it as best as I could"
would a 'professional' have done it any different? genuinely don't know, to me it looks like a fully professionally rebuilt item that couldn't have been done any better. even the welding
Either it's built cheaply and breaks easily or that machine was really abused to end up in that condition. Good job fixing it!
I can guarantee that it was super abused - it was a service machine in a company and many people used it.
@@DonnDIY That would explain it. I've rebuilt a few of those Argos but not in such depth as you. You are a true tradesman!
That gearbox will outlast the whole vehicle
👍👍👍!!!
i don't think anyone notice but when he showed the bearing, spearing, and the little nut that keep the gearbox in place he but tremendous amount of locktight .
i meant gearbox in gear oops my bad
The bean counters had a lot to say in the making of this final product…save money on using thinner metals and less welds…
🤘🤠
👍👍👍
I wouldn"t have used Coppergrease, bad experience with water if prefer ceramic grease it won"t get sticky over time
👍
❤❤❤
👍👍
That cracked bracket desperately needs some reinforcing plates, or it'll eventually crack again.
You're right.👍
👍💪
Hay
👏👏👏👍
half of this work needs to be done immediately after purchase, than the designer thought to leave sharp corners next to the hole on such a loaded part ...
it would be better if you would drill a hole at the end of the crack, before welding.
great job!!!
Where is your homemade one?
In the barn.
I do not believe a Scandinavian person designed that gearbox!
