Product brief: 20T X26 midshaft pully for Medius X26

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

The component concentrates on fit and drivetrain performance rather than cosmetic effect. In application it alters gear mesh alignment, torque transmission between the midshaft and neighbouring gears, and can affect compliance of the drivetrain under load. When replacing or tuning this pully, verify tooth profile alignment and clearances to the spur gear and any idler parts to prevent premature wear.

Installation advice: inspect mating bore and keying surfaces for burs, confirm runout and axial play after assembly, and use the torque values specified in the Medius X26 kit documentation. Conduct routine checks after initial running to ensure stable mesh and bearing loads.

Specifications

  • Item: Midshaft Pully 20T X26
  • Material: Steel
  • Model Number: SER402197
  • Compatibility: Medius X26 steel EP (SER400052)

This Serpent midshaft pully is a direct replacement for the Medius X26 steel EP drivetrain, engineered to maintain accurate tooth profile and robust steel construction for reliable drivetrain behaviour and tuning consistency.

How can I confirm fitment before final assembly?

Trial-fit the pully into the midshaft assembly, check for correct seating on the key, and verify clearance to the spur and idler gears prior to tightening fasteners.

Does material choice affect long-term wear?

Yes. Steel provides greater wear resistance and resists deformation under torque, which helps maintain mesh over longer running periods compared with softer materials.

Are any adjustments typically required after swapping the pully?

After installation, check mesh and bearing preload, correct any axial play, and re-inspect after the first runs to ensure nothing has shifted.

What signs indicate the pully needs service?

Look for uneven tooth wear, visible nicks, increased noise or backlash, and any unusual bearing play; these indicate service or replacement is needed.

How should I protect the pully from premature wear?

Keep the drivetrain clean, avoid abrasive contaminants, check gear alignment regularly, and ensure bearings remain properly lubricated and seated.

Where do I find the original part references?

Refer to the Medius X26 kit manual or the product listing referenced by your vendor for the recommended fasteners and torque settings when fitting the pully.
