Description

  • AndyMark EVO Shifter Short Hex Shaft, StageA 3 Stage - 09.54:1 Ratio 2:1, StageB 3 Stage - 21.72:1 Ratio 2:1
  • Incorporates two-speed, shift-on-the-fly gearbox
  • Utilizes improved 4-tooth dog shifting method
  • Compatible with CIM or NEO motors
  • Features robust AMPCO 18 Bronze gear
  • Employs pneumatic shift method for smooth transitions

The AndyMark EVO Shifter Short Hex Shaft, StageA 3 Stage - 09.54:1 Ratio 2:1, StageB 3 Stage - 21.72:1 Ratio 2:1 represents a significant advancement in shifting transmission gearboxes. This two-speed, shift-on-the-fly gearbox incorporates an enhanced 4-tooth dog shifting method, allowing for smooth and efficient 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 performance. The gearbox is shipped assembled, though motors are not installed.

Significant improvements have been made over previous models, including a robust 1/8" diameter shoulder screw and a dog gear made from AMPCO® 18 Bronze, which provides added lubricity and strength. The gearbox features a super-strong shift block assembly with a larger bearing and threaded steel housing, enhancing durability. The input stage utilizes 32 DP gears and a 15-tooth pinion gear, achieving a high 85:15 first stage reduction. Users can independently select high and low ratios, and the gearbox supports various encoder options, including the US Digital E4T.

The EVO Shifter employs a pneumatic shift method, powered by a spring-extend pneumatic cylinder, allowing for gear shifts even during acceleration or deceleration. The gearbox is designed with aggressive weight reduction features and can be mounted to an AM14U family chassis or a 2"x1" box tube frame using existing mounting plate holes. The optional third stage provides an additional C ratio choice, further enhancing its versatility.

Note: Ensure proper greasing and break-in procedures are followed for optimal performance and longevity of the gearbox.
