Medius X26 Midshaft Pully 20T X26 for Medius X26 - SER402197 Serpent  [SER402197]

Medius X26 midshaft pully — 20T X26 details

This midshaft pully is a scale RC drivetrain component intended for use in the Serpent Medius X26 steel EP kit (SER400052). It functions as the midshaft gear element that transfers rotation within the mid-engine drivetrain arrangement and is manufactured to a 20-tooth X26 profile that matches the Medius X26 geometry.

The part is focused on correct fitment and consistent drivetrain behaviour rather than visual change. In practice it affects gear mesh alignment, torque transfer between the midshaft and surrounding gears, and can change drivetrain compliance under load. When replacing or tuning this pully, check tooth profile alignment and clearances to the spur gear and any idlers to prevent premature wear.

Installation notes: examine the mating bore and keying surfaces for burrs, confirm runout and axial play after assembly, and use the hardware torque values referenced in the Medius X26 kit documentation. Carry out routine checks after initial runs to verify stable mesh and bearing loads.

This Serpent midshaft pully is a direct replacement for the Medius X26 steel EP drivetrain, prioritizing accurate tooth profile and durable steel construction to help maintain gearbox reliability and consistent tuning results.
