How To Build IRS Chain Drive Spool (No Lathe) For Crosskart/Buggy High HP Engines

How to build a chain drive spool/rear diff for crosskart. This drive spool was designed for my R1 crosskart (KJ Raycing style chassis) This is my 5th design.
Made a few prototypes after working the bugs out. i came up with this design. Made for buggies with bike engines that have 100+ hp. Has held up to the 180 hp R1. Uses R1 sprocket pattern so you dont have to get custom sprockets.
Next video i show how to mount to a crosskart!! STAY TUNED!

Welcome!

Dude im thinking of using a Subaru differential with cv axles as my rear drive, ill get a custome mount so the sproket can bolt to the differentials input and ya hopefully call it a day

[@Xkarts200]

I just looked into a subaru differential. That sounds like a really good idea. I didn't know they were that small. What kind of buggy r u building??

[@VAN-Geaux]

Is it practical to drill the grease fitting and weld hole prior to installing the bearings? seems like those metal pieces will destroy the bearings.. Possibly...

[@Xkarts200]

@VAN-Geaux yes that sounds like a good idea.

[@kevinwest8487]

just curious, why do you put grease in there when those look like sealed bearings?

[@Xkarts200]

To keep it cool and something to fill the space so it doesn't get full of water or something.

[@yournamehere15]

Will the right and left caliper work? Or does it need to be right side?

[@Xkarts200]

@@yournamehere15 either will work. The only difference is where the bleed screw is

[@Joe-sw3sv]

What is the total width ? Wheel flange to wheel flange ?

[@Xkarts200]

Its about 57 to 60 in

[@patrickcarney3110]

What year/range carrier did you use off the 800 Ranger?
