Serpent SER402197 Midshaft Pully 20T X26 Midshaft Pully for Medius X26 steel EP  [SER402197]

Midshaft pully, 20T X26 overview

This midshaft pully is a scale RC drivetrain component intended for use in the Serpent Medius X26 steel EP kit (SER400052). It serves as a midshaft gear element to transmit rotation within the mid-engine drivetrain layout and is specified as a 20-tooth X26 profile suitable for the Medius X26 geometry.

The part focuses on fit and drivetrain behaviour rather than cosmetic change. In practical terms it affects gear mesh alignment, torque transmission between the midshaft and adjacent gears, and can influence drivetrain compliance under load. When replacing or tuning this pully, verify tooth profile alignment and clearances to the spur gear and any idler components to avoid premature wear.

Installation notes: inspect mating bore and keying surfaces for burrs, confirm runout and axial play after assembly, and use the correct hardware torque values specified by the Medius X26 kit documentation. Routine checks after initial runs help confirm stable mesh and bearing loads.

This Serpent midshaft pully is a direct replacement component for the Medius X26 steel EP drivetrain that prioritizes correct tooth profile and durable steel construction to maintain drivetrain reliability and predictable tuning behaviour.
