The AndyMark EVO Shifter Short Hex Shaft, StageA 3 - 05.45:1 Ratio 1.14:1, StageB 3 - 12.41:1 Ratio 1.14:1 represents a significant advancement in shifting transmission gearboxes. This two-speed, shift-on-the-fly gearbox incorporates an enhanced 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.

The EVO Shifter introduces several improvements over previous models, including a more robust dog gear with increased material strength and a new shoulder screw design. The dog gear is crafted from AMPCO® 18 Bronze, providing enhanced lubricity for smoother shifting. Additionally, the shift block assembly has been fortified with a larger bearing and threaded steel housing. The input stage features 32 DP gears and a 15-tooth pinion gear, facilitating a high first-stage reduction. Users can independently select high and low ratios, with the option to swap ratios as needed. The gearbox also supports various encoder options, enhancing its adaptability.

The gearbox is designed with aggressive weight reduction features and allows for easy disassembly and reassembly without concern for gear orientation. It can be mounted to an AM14U family chassis or a 2"x1" box tube frame using existing mounting plate holes. The EVO Shifter employs a pneumatic shift method, utilizing a spring-extend pneumatic cylinder for shifting, which can be executed while a robot is in motion.

Note: Ensure proper greasing of the gearbox for optimal performance and longevity, and follow recommended procedures for pinion installation to maintain safety and functionality.
