Want more speed from your Evolution series XMODS? Upgrade it. This tutorial describes how to do a basic motor upgrade using the XMODS Evolution Stage 2 Motor Upgrade Kit, replacing the 27,000 Stage 1 motor with the 30,000 Stage 2 motor and a new gear setup.
For this tutorial I'm putting the Stage 2 motor into the XMODS Hummer. Start by removing the body then removing the back tires using the tool provided in the starter kit.
Removing Plastic Strip Holding Motor in Place
Remove the top plastic piece that holds the motor in place. It's the black piece with the 4 cut slots that goes across the top of the motor that is held in place with two screws.
Remove Cover on Spur Gear
Remove the two screws that hold the drivetrain cover in place to gain access to the spur gear.
Remove Motor and Plastic Spacer
Remove the motor and the plastic spacer (motor shim) that was underneath it.
Remove the Wheel Hub Cover and the Spur Gear
Remove the wheel hub cover. One screw holds it in place. Although it might not be apparent in the photos, the wheel hub is just large enough that it prevents you from taking the spur gear off so it must be removed.
Once it is out of the way you can remove the spur gear.
Choose a Gear Setup
At this point you need to decide if you want to go with more top end speed or more torque.
In the kit there are gear setups color-coded with orange or green. The orange setups are for more torque or more punch off the line. The green setups are for more top end speed.
There will be three pieces that you'll use for each setup: a spacer (motor shim), a spur gear, and a pinion gear.
The parts are labeled as to the number of teeth on the pinion gear and the teeth on the spur gear.
The orange setup comes with 2 different spacers, 1 25-tooth spur gear, and 2 different pinion gears (8 tooth and 9 tooth).
The green setup comes with 4 different spacers, 1 23-tooth spur gear, and 4 different pinion gears (9, 10, 11, and 12 tooth).
For each gear setup you match up the pinion gear with the spacer labeled for that size of gear -- in other words, for the orange high torque setup you would use the spacer labeled 9-25 with the 9-tooth pinion gear and the 25-tooth spur gear.
Other parts in the kit are the 30,000 Stage 2 motor, metal motor heat sink (used in Step 10), and a pinion gear removal tool (Used in Step 8).
The different sizes of pinion gear will give you varying degrees of speed and torque. It's a matter of personal choice which size you choose. If one doesn't give enough speed or power, try the next higher number.
In this upgrade we're going for as much top end speed as we can muster so we chose the green 12-23 setup: the 12-tooth pinion gear and the 23-tooth spur gear along with the spacer labeled as 12-23.
Put in New Spur Gear and Spacer in Gear Box
Put the new spur gear in with the small end facing inward and larger backside facing out. Then replace the wheel hub cover that you removed in step 5.
Put the new spacer into the gear box with the label facing down.
Replace the Pinion Gear
If you plan to keep the original motor and only change the gear ratio you'll need to remove the old pinion gear from the motor. Gently pry the pinion gear off the stock motor. (photo 1)
Install the new, larger pinion gear onto either your stock motor or the Stage 2 upgrade motor.
If replacing the stock motor with the Stage 2 motor, first remove the stock motor by removing the leads from the circuit board. Simply unscrew the black and red wires where they attached to the circut board.
Whether you're using the Stage 2 motor with the new pinion gear or you've simply replaced the pinion gear on the stock motor, put the motor into the rear gear box. Instead of replacing the plastic strip you removed in Step 2, hold the motor in place with the metal heat sink that came in the upgrade kit. Be careful not to tighten the motor mount screws too much because it will cause binding and strip the gears.
If you've replaced the motor you'll need to attach the new leads from the motor to the circuit board -- positive to positive and negative to negative.
In this upgrade kit the red lead is positive (+) and the black lead is negative (-). Simply screw the leads into the appropriately labeled spots (where you removed the leads from the old motor).
The upgrade is now done. Put your wheels back on. Put the body back on. Take your newly upgraded XMODS out for a test drive.
