[0:00] Hey guys, Ryan here at SuperATV. I’m going to take a quick minute to show you guys how to install the SuperATV Rapid Engagement Front Differential. Step on down here and take a closer look.
As you can see, I have already removed all the factory internals of this differential, so now it’s time to install the SuperATV parts. Take your ring gear and put it down into your differential. Make sure it’s sitting in there all the way.
[0:25] Take your pinion and slide it in. Then take your spanner nut and thread it in there. This nut here need to be torqued anywhere between 121 foot-pounds and 142 foot-pounds. So we would take our spanner nut tool and thread it in, and then remove your tool.
[1:19] Now we are going to shim the differential. The factory front differential came with three. SuperATV provides four, just in case your tolerances are not where they’re supposed to be. So we are going to start out with three shims. Install them on the top, then take your cover and slide your cover over them.
We want to start by putting two bolts into the differential cover, just to hold the cover in place while you check the tolerances. After you get your cover on, remove the bolt from the back of your pinon.
[2:18] Install the backlash tool and, when that is set up, a dial indicator. We want to make sure your dial indicator is zeroed and check your backlash. You want to make sure it is between .05 millimeters and .36 millimeters, which this one is, just in tolerance.
Shimming the front differential is a very crucial part of the whole process. If you don’t have the specialty tools then we recommend taking it to a dealership to have them install it.
