Medius Midshaft Pully for Tuning - Arrowmax AM-910033  [AM-910033]

Overview of the Medius midshaft pully and installation

The Arrowmax AM-910033 Medius Pully Midshaft B is an RC midshaft pully offered as a replacement or upgrade for driveline systems. The content is composed to help modelers evaluate fitment, installation and tuning without promotional language.

Design and purpose: This Medius pully is intended to sit in the midshaft position and maintain correct belt or gear alignment. It enables fine-tuning of gear mesh and chassis setup while leaving core gearbox components untouched.

Installation notes: Check bore sizing, shaft clearance and screw compatibility before fitting. Confirm axial alignment and ensure adjacent components have sufficient clearance, tightening fixings in a way that avoids lateral bearing preload.

Tuning guidance: Apply small incremental adjustments to pully position or shims and then spin the driveline slowly by hand to confirm smooth engagement. Re-check for any binding or unusual resistance after changes.

For those replacing a midshaft pully or trialling Medius components, the AM-910033 offers a straightforward way to manage gear alignment and refine driveline behaviour without major chassis changes.
