Description

  • AndyMark EVO Shifter Short Keyed Shaft, StageA 2 - 18.71:1 Ratio, StageB 2 - 05.45:1 Ratio
  • Advances shifting gearbox design
  • Supports CIM or NEO motors
  • Utilizes strong AMPCO® 18 Bronze
  • Features aggressive weight reduction
  • Allows independent gear ratio selection

The AndyMark EVO Shifter Short Keyed Shaft, StageA 2 - 18.71:1 Ratio, StageB 2 - 05.45:1 Ratio represents a significant advancement in shifting transmission gearboxes. This two-speed, shift-on-the-fly gearbox is designed with an improved 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 the use of AMPCO® 18 Bronze for the dog gear, which provides enhanced strength and lubricity. The shift block assembly has been reinforced 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 have the freedom to 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, utilizing a spring-extend pneumatic cylinder for reliable performance even under dynamic conditions. The gearbox is designed with aggressive weight reduction features, making it suitable for mounting on an AM14U family chassis or a 2"x1" box tube frame. The robust construction includes 4140 steel output shafts and pocketed aluminum side plates, ensuring durability and efficiency.

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 before applying Red Tacky Grease periodically.
