Crown Second Reduction Gear CR090726 – E-4099

Positioned in the second stage of the drive train, the CR090726 reduction gear takes the output from Crown's first reduction stage and steps it down further, building the torque multiplication an electric lift truck needs to move a loaded pallet from a dead stop. Reduction gearing trades rotational speed for torque: the motor spins fast but with comparatively low torque, and each gear stage cuts speed while multiplying torque, so by the time power reaches the drive wheel the truck has the pulling force to get a loaded pallet moving without stalling the motor.

Because this gear carries that torque multiplication under constant load cycling, wear shows up as gear noise, vibration, or slop in the drivetrain that a technician can feel through the truck before it becomes an outright failure. Backlash between worn teeth also shows up as a delay between operator input and truck movement, since the gear has to take up slack before it transmits power cleanly.

At 13.7 pounds, this is a substantial cast gear built for Crown electric lift trucks, sized to handle repeated torque cycling through a full working shift. Replacing a worn second reduction gear restores proper tooth mesh and quiet, consistent power delivery to the drive wheels, correcting both the noise and the response lag a worn gear introduces.
