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 Motors or other motors attached to the AM Planetary gearbox.
This gearbox is shipped in kit form, not assembled.

This box is actually too tough
I heard that Kim Wilson personally called AndyMark and asked them to retire this product.
"Why not have the different ratio, materials, and shaft size/type options available for purchase, since the kit comes unassembled?"
motor covers one bolt hole
Once 3 CIM motors are mounted, one of the 4 bolt holes used to hold the toughbox together and for mounting is partially covered making it impossible to put a bolt in it. Otherwise it is working very well for us.
"Three Motor Toughbox"
"It's a good gear box, not hard to assemble, but if you plan on mounting it to an AM14U it is difficult and you have to make a bracket for it or turn it. Other than that it is a good gear box."
