TB3 Toughbox Classic 3 Motor 12.75:1 Gearbox

Product Availability: This gearbox is the predecessor to the EVO Slim. Once parts supplies for this gearbox are exhausted, it will be retired.

Product Usage:
All AndyMark gearboxes require grease for proper operation and long life. We suggest using our red tacky grease, am-2768. We also encourage that the user powers the gearbox continuously for 30 minutes without grease to allow the gear teeth to wear in. While we do design with short run times in mind, this 'run in' period for smooth gearbox operation, is recommended. Once this is completed, thorough grease of the gear teeth periodically to ensure smooth operation.

This is a version of the popular Toughbox gearbox, but with unique side plates which can accept three (3) motors. These motors can be CIM Style Motors, or the NEO. 

This gearbox is shipped in kit form, not assembled.
