The most reliable tried, and true gearbox for FIRST Robotics Competition teams. This gearbox has been proven on the field of competition for ten years.
The Toughbox Mini uses the same interior parts as our bulletproof Toughbox. Shipped in an unassembled kit of parts, you save. Hardware is included with the gearbox for attaching two NEO, or CIM style motors.
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.

AndyMark is doing great this year
I really think this is the best service year yet from AndyMark. Everything ships quickly.
"poor fit on round parts of output shaft"
"The output drive shaft did not want to go in either bearing (shaft too large or bearings too small). The shaft also would not fit into the 500key hub purchased at the same time. I wound up running the gearbox and using it as its own lathe to file down the shaft. I also had to file down the back shaft diameter (though less) in order to fit the encoder kit. A retainer clip similar to the am-0033 but 1/2" i.d. would be great to help keep the key inside a hub without needing a shaft collar."
