7075 aluminium 1st gear by Arrowmax for MRX5

Arrowmax supplies this 1st gear for Mugen MRX5 applications under part number AM-MRX5-A0001. The gear is produced from 7075 aluminium with a hardened surface and is intended as a direct replacement for the transmission first stage where wear or tooth damage has occurred.

Replace a worn 1st gear when you detect play or rounded tooth profiles; a new gear restores proper engagement and keeps torque transfer smooth through the gearbox. This is a one-piece gear designed to fit with the MRX5 gearbox components and standard spur and pinion configurations for that chassis.

During installation, confirm correct gear mesh and backlash with the motor pinion and spur, check that bearings are seated, and ensure the gear spins freely before final reassembly. Do not overtighten clamps or grub screws to avoid distorting the mounting. Applying a light gear lubricant to the face will ease initial wear-in.

Can I use aftermarket pinions with this gear?

Yes, the gear works with standard spur and pinion setups used on MRX5 chassis; confirm tooth count and shaft spacing when fitting aftermarket pinions.

Does 7075 aluminium need special care?

7075 is robust but still benefits from clean running conditions and occasional inspection; remove grit, check mating parts, and apply light lubricant to reduce friction.

What are quick fit checks before running?

Confirm proper mesh and backlash, ensure bearings fit squarely, tighten fasteners to recommended torque without overclamping, and spin the gears slowly to verify smooth engagement.
