Rear axle

[Drmmr6622]

i am building a off road go kart and i need some advice on my rear end. i have a setup to build a independent suspension. i just need some help finding u joints and other stuff so i can get this thing working. i put up a pic, if that will help u better understand my setup. i currently have a snowmobile engine in there so i need something to handle the power.

How many cc's is it? If more than about 600 then I'd be going CV joints for reliability.

If not, people have had good luck with uni joints from land rovers...

 

[Drmmr6622]

its under 600


and where would i find the u joints at is there a place i can buy them new or just post something on craigslist.

tractor supply sells pto shafts with universal joints. http://www.tractorsupply.com/webapp...45|14402|28212?listingPage=true&Special=false

then get another square tube and then you have a slip joint like a drive shaft. i seen the guys on xtreme 4x4 on spike build driveshafts like this for a budget rock crawler. works very well.

pto shafts from old farm equipment would be cheep
1000 ones would be better than 540, if you want really heavy ones get a shaft for the big 1000 (the big 1000 is just a bigger version of the thousand) the picture are the male end, the pto shaft will have a female end the way to tell the difference is the splines

Hi , I think your gonna be similar to my rear setup , lol , I just got all my shocks yesterday , I`m gonna be using some front forks on the rear also , I`m going to use a Jackshaft , have the ends turned down to 3/4" , then put one of these on each end with a high grade bolt through it and the jackshaft to keep it all together , will use a short 6" axle on the other end for the wheel hub , using pillow blocks on it , I will have to shorten the center section of these steering shafts for the right length , theres a U-Joint on both ends , the center sections are also a slip joint fit to extend or compress , the shafts are off a 1991 Jeep Cherokee , theres 2 different ones used in the Cherokee`s , Aluminum end ones and steel end ones , the steel end ones have a 3/4" hole in the yokes , the Aluminum end ones have a 5/8" hole in the yokes , these are about $ 135 average for one , but in the wrecking yards they can be had Cheap , here in my Pull It Yard I can get 2 of them for # 30.00 , its what I`m going to use , I do only have a 185cc Trike engine though , I still think they should hold up to your engine ,, Bill

Just keep in mind steering shafts aren't designed to spin that fast, so they may wear out quite quickly. Might be alright tho. GL.

Those steering shafts won't hold up to that sled engine. I'm not sure if you are using a single a arm or dual. But for the engine you are using you need to go to a VW axle or a axle from a small car.

Theo, you need to make a thread of all the different buggies/karts you've made, they all look so nice...

I would like to take credit for that build, but it's not mine.

i've seen this cart on youtube

 

[theo]

Also if you look you will see that this guy is using a comet diff. There was several guys using them with the sled engine.

[Drmmr6622]

That is almost the exact same engine as mine.

 

[Drmmr6622]

ok I'm looking at getting vw cv joints and axles but i need to know how i can make the 6 screw pattern into like a solid 1 in axle like in the kart above

 

[theo]

You can buy them, but you have to have deep pockets. To make them you need a weldable hub and then you have to make a disc with the same bolt pattern as the VW CV's.

this website has just what your looking for

Go to your local pick a part junkyard. My local sells complete CV axles for ~$20. Then you just have to have the ends machined to 1" keyed.

Looks like it has a loose nut on the right A-arm
