The AndyMark EVO Slim 4.77:1 Ratio, 3.875in Shaft Length is a high-performance, lightweight gearbox designed for competition robots. It offers a robust solution for creating efficient drive trains, sharing many components with the EVO Shifter, including weight-relieving features, steel gears, and aluminum plates. This gearbox is provided in kit form and is capable of accommodating up to three motors, although motors are not included.

The gearbox utilizes a 15 Tooth 32DP pinion gear, which is included and does not require a key. For those who prefer not to install the pinion themselves, motors with pre-installed pinions are available. The installation of the pinion on a NEO motor requires a 3-ton arbor press due to the interference fit, while the CIM motor may require either a slip fit or a press fit. In both cases, the application of red Loctite 271 is recommended to ensure secure attachment.

The EVO Slim for CIM is compatible with either the E4T Optical Encoder Kit or the SRX Mag Encoder, necessitating a 3D printed mount plate. Future versions will include appropriate holes in the motor plates to accommodate the Encoder Mount Pad. When using the SRX Mag Encoder, additional mounting hardware is required.

Note: Ensure proper installation procedures are followed to maintain safety and performance standards.
