Man I like Kris Harbour videos. He always owns up to the problems he runs into. In this case He spec'ed a 20:1 gearbox that did NOT use thrust bearings. The manufacturer didn't use them because the they intended the motor to drive the fast end and reduce to a slow speed for a conveyor belt. He's using it in reverse and because it uses helical gears, that changes the anticipated direction of thrust on an intermediate shaft. Lesson leared (ha!).... drive direction matters when using helical gearboxes.
