  • Configured with two or three interior stages

The AndyMark EVO Shifter am14u Family Hex Shaft, StageA 3 Stage - 06.86:1 Ratio 1.14:1, StageB 3 Stage - 18.71:1 Ratio 1.14:1 represents a significant advancement in shifting transmission gearboxes. This two-speed, shift-on-the-fly gearbox incorporates a refined 4-tooth dog shifting mechanism, allowing for seamless transitions between gears. It is compatible with two CIM or NEO motors and can be configured with either two or three interior stages, offering flexibility in output shaft selection. The gearbox is delivered assembled, though motors are not pre-installed.

Enhancements in this model include a robust dog gear with four dogs on each face, crafted from AMPCO® 18 Bronze, which provides increased strength and lubricity compared to previous stainless steel designs. The shift block assembly has been fortified with a larger bearing and threaded steel housing, ensuring durability. The input stage utilizes 32 DP gears and a 15-tooth pinion gear, achieving a high first stage reduction of 85:15. Users have the autonomy to select their preferred high and low ratios, with the option to interchange them as needed.

The gearbox features aggressive weight reduction techniques and is designed for easy assembly, with cluster gears that are identical on both sides. It can be mounted to an AM14U family chassis or a 2"x1" box tube frame. The pneumatic shift method employs a spring-extend pneumatic cylinder, enabling shifts even during acceleration or deceleration. The gearbox's weight ranges from 2.9 to 3.5 pounds, depending on the stage configuration.

Note: Proper greasing is essential for optimal operation and longevity of the gearbox. It is recommended to run the gearbox for 30 minutes without grease for initial wear-in, followed by periodic application of grease to the spur gears.
