Introduction

The Orangatang motor liners on your Unlimited kit or complete are designed to have a snug fit on the motors for smooth and efficient operation.
In manufacturing, a light application of lubricant aids in installation while also helping the motor liners roll quietly.
Over time, you may notice a slight increase in noise as this lubrication dries and wears.
This won’t negatively impact your ride, but a bit of simple periodic maintenance can keep you rolling in silence.

Liner Removal

Using the hex key on your skate tool, remove the four bolts attaching the metal plate to your motor.
With the bolts removed, gently pry the plate off the motor.
Usually, you can slide the motor liner off of the motor by pulling the board and the motor liner in opposite directions.
If the motor liner is particularly dry, it can be a little difficult to remove.
Placing the board on its side and stabilizing the opposite wheel with your feet can give you good leverage to lovingly coax a stubborn liner off its motor home.
This process can also be used to replace your old motor liners with new ones.

Clean any excess dirt or debris from your motor and motor liner.
Apply a light layer of silicone-based spray or grease to the inside surface of the motor liner.
If you don’t have a silicone-based lubricant, you can also use a bit of dry bar soap.
Don’t just use any old lube you have laying around. Examples of what NOT to use include WD-40, lithium-based grease, 3-in-ONE, olive oil, etc.

Align the grooves with the motor and slide the motor liner on until it seats firmly against the inner metal plate.
Carefully clean up any excess lubricant, especially on the outer surface of the motor liner where it could pose a safety hazard while riding.
Re-install the outer metal plate, taking care to not overtighten the hex bolts.
Take your board for a spin. You should hear a reduction in noise as everything settles in.
Be proud of the smooth and silent ride you’ve taken the time to maintain!
