# NEO & Other 500 Motors

{% hint style="info" %}

## Follow these instructions if you are using a Neo Brushless V1.1, Flacon 500, Kraken, or CIM Motors. Use the below information to determine the correct [MAXPlanetary Input Coupler](https://www.revrobotics.com/maxplanetary-input-couplers) for your motor. 

* NEO Brushless V1.1, CIM, or other motors with an 8mm output shaft - MAXPlanetary 8mm Keyed Input Coupler Kit (REV-21-2108) 
* Falcon 500 or other motors with a 14T output shaft - MAXPlanetary 14T Spline Input Coupler (REV-21-2124) 
* Kraken or other motors with a 15T output shaft - MAXPlanetary 15T Spline Input Coupler (REV-21-2138)

## NEO Multi-Stage Assembly Instructions

For assembly you will need a 5/32" Allen Wrench.

{% hint style="success" %}
If your robot requires shaft retention in the gearbox, follow the [Shaft Retention Assembly ](/ion-build/build-guides/maxplanetary-gearbox-assembly/shaft-retention-assembly.md)instructions now before proceeding.

{% hint style="warning" %}
When building your gearbox make sure the highest gear reduction is closest to the motor.&#x20;

### Greasing Guide

MAXPlanetary Gearbox Cartridges are pre-lubricated and sealed. If during maintenance you find that a cartridge needs more grease, we recommend using a Molybdenum Grease to apply more lubrication such as [Synthetic NLGI #2 Molybdenum Grease](https://www.amazon.com/Schaeffer-Manufacturing-02742-029S-Synthetic-Grease/dp/B00JF2LBQ6?th=1) or [MOLYKOTE® G-2008 Synthetic Tool Gear Grease](https://www.mmtoolparts.com/dewalt-grease-n017298).
