My slide motor /gearbox assembly failed, and the 133612 has been replaced by LCI Replacement 18:1 Venture Motor and Driveshaft with Right Angle Gear Box - LC117292. Beware that the replacement motor failed in less than four months. The gear ratio on it is 18:1, whereas the 133612 is 18:1 from the motor to the gearbox and then 360:1 from the gearbox to the shaft.
