That's the first homemade portal boxes ive ever seen and they look awesome. I hope the forty chain is strong enough for the final drive if its not fifty will be. And thats one thing i like about the polaris quads especially the older ones is that the parts are pretty standard size lots of one inch shafts and i think some of the u joints are the same size as power take off (pto) parts

Thanks! I was originally going to use 520 chain as that seemed like the logical choice. I had a problem sourcing the 520 sprockets I wanted but they did have 420 size in stock. I thought about it and I think the chain has less torque transferred through it with the 3-1 gear reduction. The top 12 tooth sprocket is pulling a 36 tooth sprocket. A sprocket is just a lever. Bigger the driven sprocket, the more leverage. Thanks for the info about the Polaris.

Your original build for this kart inspired me to build my own version. I literally just came back on YT to s find a method to make portal hubs, and found your video!!

That’s crazy! Thanks for the comment. Good luck with your build.

If you used meshed gears instead of chain it should be stronger and no worries of the chain breaking. Nice job though. Only video ive seen that shows the building of portal axels.

That is pretty spectacular! Also very simple to build if you have a lathe & a mill ( I have both). You sir are very ingenious. I am very impressed. Thank you. Thank you very much.

Интересно, как будет работать привод, когда на одной оси крестовина и шрус? Ещё и расчёт на большой ход рычага. Я думаю, что будкт большое биение, на одной оси должно установлено, либо только крестовины, либо только шрусы.

Start with purchasing an inexpensive mig welder and a 4 1/2” grinder. You can build what you dream of.

i didnt see you using a lathe, did you find tubing that fit the bearings that perfectly ? if so what tubing and bearings? i want to scale up and use on a midsize 4x4 . wonder if industrial chain will take the torque..
@kartbuilds6979 ай бұрын
I used a lathe. Roller chain with tensioner(designed to take reverse load also) will work. The trick is to size it correctly. To big and it’s extra parasitic drag. Too small and it fails. Mine were one size too small.

So basically, you used two CV Alex per side, both cut at different points and modified differently. One cut to accept the wheel hub and Hilliard clutch on the bottom, and one keyed to accept the jack shaft sprocket in the top?
@kartbuilds6978 ай бұрын
Top axle is a hardened cv shaft. I drilled a 3/8 hole using a concrete drill bit to fasten the sprocket. The bottom axle is a 1” gokart axle with 1/4 keyway.

I saw this before .they used to make them on old land rovers . What about if I use a tranferbox chain .. for my rig .would that be stronger ? Cause I went into skf website and I got lost in there 😂😂😂 .

That is a possibility. I sized my chain one size too small and they eventually broke.

Why did you use heims on bottom instead of ball joint to match the top?whats holding the lower shaft on the back side?could you explain how your going to seal it up a lil better?
@kartbuilds697 Жыл бұрын
The lower shaft has a small stop welded on the end. Watch video at 8:27 seconds to see it. It’s hard to see it just looks like a bunch of weld. The lower axle and upper cv shaft will have a cover plate over bearing with rtv silicone to seal unit. If I used a lower ball joint I was afraid it would interfere with lower axle cover. Thanks for the interest.

Unfortunately it’s not for sale at the moment. I’m outfitting it for rock crawling the Rubicon trail. The 3-1 gear reduction in the portal boxes makes it a crawler. Top speed from 50mph to 15 mph.
