New Guy with New Toys

I have some before and after pictures from the work i did to my kart today. I am planning on stretching the passneger area back to make it longer, and making the rear area wider so I feel comfortable about running a solid live axle. Cutting off all that I did cut the weight down some, but there is still some more reductions to be found.

That's looking a bit better, not so much clutter. Be aware though, you may have to add back on to it for engine mount, etc

Well i found were all the weight was coming from, it was that ****ed differential hanging off the back of this thing. I took some measurements and I am going to post them here (they are mostly for my benefit but if anyone has any comments then feel free).

Full Kart Length - 61 inches
Width - 14 1/2 inches
Spindle Length - 7 1/4 or 7 1/2 inches (probably gonna change these out)
Front end width (spindle end to spindle end) - 47 3/4 inches
Width in necked down area behind Passenger - 8 3/4 inches
Passenger Area Length - 41 inches
Rear length - 21 inches

Now I just need to find out how long of an axle I need, what size wheels and tires, sprocket size, and a few other things and this thing might be moving under its own power before Fall time.

Wait up; total length = 61"
Passenger Area Length = 41 inches
Rear length = 21 inches
In my day 41 + 21 = 62

I would think, since your front end is 47 3/4" you would go for a 4' axle. Are you not using the original wheels?

Woops, you caught me, rear lenght is 20 inches. so a 48 inch rear axle? i might reuse the original rear wheels as they are keyed, but the fronts will be replaced because they actually go with boat trailer hubs (5 lug but not sure of the lug spacing). Although if it does come down to it (money) I might just reuse all the wheels and just go with smaller tires. Since you suggest a 48 inch axle, where at on the axle should I put the bearing hangers? Like how far in from the end of the axle?

Ah, now we come to the part where you have to add back on. If you mount your bearings on the original frame, your axle will bend on the first bump. Your bearings should be as close to the end of the axle as possible so, to answer your question; it depends on where your wheels sit. Once you've figured that out you'll then need to build the rear frame to suit.

So, to recap: source an axle,
slide the bearings in the hangers onto the axle
fit wheels to axle
set bearings 2" - 3" in from the edge of the inflated tyre
build a frame over the hangers & attach to main frame.

Have I made your day?

I actually figured I was going to have to build on to the rear of it, I just didnt know where the bearings were suposed to go
