Replacement 19T pulley for MTX-5 setups

The Arrowmax AM-MTX-T2202A is a 19-tooth pulley manufactured from 7075 hard aluminium, specified for RC drivetrains and matched to MUGEN MTX-5 style installations. It serves as a direct swap or an upgrade where the pulley geometry and tooth count match, offering tighter gear engagement and a more consistent drive feel on electric models.

Installation usually involves swapping this pulley onto the MTX-5 gearbox output or intermediate shafts. Verify shaft clearance and alignment before tightening, ensure grub screws or pins are secure, and confirm smooth rotation after assembly to prevent binding. The component is intended for tuning the drivetrain rather than modifying basic gear ratios.

Fit and compatibility notes

Compatible with Mugen MTX-5 parts that accept a 19-tooth pulley with the same mounting interface, suitable for competition or club-level electric RC cars.

Do I need special tools to fit this pulley?

Basic hand tools are sufficient for most installs, but a torque driver for grub screws and a dial gauge for checking shaft runout can help achieve the best result.

Is there any balancing required?

Most 7075 pulleys are well balanced from the factory; if you run at very high RPMs you can check balance on a simple balancer and correct minor eccentricity if needed.

Will this change my gear ratio?

No, the tooth count remains 19T so primary ratio is unchanged; the part is for durability and engagement quality rather than altering final drive ratios.

How should I inspect it after first runs?

Check for even tooth wear, confirm set screws have not loosened, and listen for unusual noise; re-torque hardware after the initial break-in run.
