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

20T X26 midshaft pully — technical summary

This midshaft pully is a scale RC drivetrain component created for the Serpent Medius X26 steel EP kit (SER400052). It is the midshaft gear item that transmits rotation across the mid-engine drivetrain layout and is produced in a 20-tooth X26 profile to match the Medius X26 geometry.

The component emphasises accurate fit and consistent drivetrain response rather than appearance. Practically, it affects gear mesh alignment, torque transmission between the midshaft and neighbouring gears, and can alter compliance under load. When swapping or tuning this pully, check tooth profile alignment and clearance to the spur and any idlers to prevent premature wear.

Installation guidance: inspect mating bore and keying surfaces for burrs, confirm runout and axial play after assembly, and apply the correct hardware torque values specified by the Medius X26 kit documentation. Run initial checks after installation to ensure stable mesh and bearing loads.

This Serpent midshaft pully fits the Medius X26 steel EP drivetrain and focuses on correct tooth geometry and steel durability to help keep drivetrain performance predictable during tuning.
