Description

  • AndyMark EVO Shifter am14u Family Hex Shaft, StageA 3 Stage - 05.45:1 Ratio 1.14:1, StageB 3 Stage - 06.86:1 Ratio 1.14:2
  • Features two-speed, shift-on-the-fly design
  • Ensures seamless shifting with improved 4-tooth method
  • Accommodates two CIM/NEO motors for flexibility
  • Offers strong AMPCO® 18 Bronze dog gear
  • Mounts on AM14U chassis or 2"x1" box tube frame

The AndyMark EVO Shifter am14u Family Hex Shaft, StageA 3 Stage - 05.45:1 Ratio 1.14:1, StageB 3 Stage - 06.86:1 Ratio 1.14:2 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 seamless transitions between speeds. It accommodates motor inputs from 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, even if included in the order.

The EVO Shifter incorporates several enhancements over previous models, including a robust 1/8" diameter shoulder screw and a dog gear made from AMPCO® 18 Bronze, which provides added lubricity for smoother shifting. The shift block assembly is reinforced with a larger bearing and threaded steel housing, contributing to the gearbox's durability. The input stage features 32 DP gears and a 15-tooth pinion gear, facilitating a high 85:15 first stage reduction. Users have the autonomy to select their high and low ratios independently, with the option to swap ratios as needed.

The gearbox is equipped with aggressive weight reduction features and can be mounted to an AM14U family chassis or a 2"x1" box tube frame. It employs a pneumatic shift method, utilizing a spring-extend pneumatic cylinder for reliable performance during acceleration, pushing, or deceleration. The gearbox requires periodic greasing for optimal operation and longevity, with Red Tacky Grease recommended for use. Additionally, the gearbox offers a 3:1 encoder ratio on two-stage versions, enhancing its adaptability for various applications.

Note: Ensure proper installation of the pinion gear using Red Loctite 271 and follow safety guidelines when handling the gearbox components.
