This Arrowmax AM-MTX-T2202A is a 19-tooth pulley made from 7075 hard aluminum intended for RC-scale drivetrains, specifically for Mugen MTX-5 platforms. It serves as a direct replacement or upgrade item where the original pulley geometry and tooth count match, and is used to refine gear engagement and drivetrain feel in small electric models.
In typical installation the pulley replaces the existing unit on the MTX-5 gearbox output or intermediate shafts. Check shaft fit and alignment before final assembly, verify set screws or retention hardware are secure, and confirm smooth rotation after installation to avoid binding. The part's role is focused on drivetrain tuning rather than altering fundamental gear ratios.
Compatible with Mugen MTX-5 spares and related MTX chassis components that accept a 19T pulley with the same mounting interface, intended for RC electric car drivetrain use.
