Description

  • AndyMark EVO Shifter am14u Family Hex Shaft, StageA 2 Stage - 07.56:1 Ratio, StageB 2 Stage - 06.00:1 Ratio
  • Incorporates two-speed shift-on-the-fly gearbox
  • Allows independent high and low ratio selection
  • Features robust AMPCO 18 Bronze dog gear
  • Offers flexible output shaft configurations
  • Ensures reliability with pneumatic shift method

The AndyMark EVO Shifter am14u Family Hex Shaft, StageA 2 Stage - 07.56:1 Ratio, StageB 2 Stage - 06.00:1 Ratio 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 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 output shaft selection. The gearbox is delivered assembled, though motors are not pre-installed.

Notable enhancements include a robust 1/8" diameter shoulder screw and a dog gear crafted from AMPCO® 18 Bronze, which provides enhanced strength and lubricity compared to previous stainless steel designs. The shift block assembly has been fortified with a larger bearing and threaded steel housing. The input stage employs 32 DP gears and a 15-tooth pinion gear, facilitating a high 85:15 first stage reduction. Users can independently select high and low ratios, with the option to swap between them as needed. Additional encoder options are available, including the US Digital E4T and the CTRE SRX mag encoder.

The gearbox features aggressive weight reduction through machined gears and plates, and the cluster gears are designed for straightforward assembly. An optional third stage offers additional ratio choices. The EVO Shifter can be mounted to an AM14U family chassis or a 2"x1" box tube frame. It utilizes a pneumatic shift method powered by a spring-extend pneumatic cylinder, ensuring reliable operation even if air pressure is lost.

Note: Proper greasing is essential for optimal performance and longevity. It is recommended to run the gearbox for 30 minutes without grease for initial wear-in before applying grease to the spur gears periodically.
