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, thoroughly grease the gear teeth periodically to ensure smooth operation. Product Overview: This is the Toughbox Mini. It is similar to the Toughbox, but it is slightly smaller in profile and is 1/2 pound lighter. The Toughbox Mini uses the same interior parts as our standard Toughbox, and is shipped un-assembled. Toughbox Mini accepts two (or one) 2.5 inch CIM Motors (not included). Hardware is included with the gearbox for attaching two of these motors. Specifications:
