Serpent Medius X26 Belt Tensioner Shaft 402201 Compatible Part  [SER402201]

Role of the X26 tensioner shaft

The Serpent 402201 belt tensioner shaft is supplied as a steel replacement for belt-driven Serpent Medius X26 kits. It is intended to set and preserve belt tension within the tensioner mechanism so the belt maintains a true path and slack-related drivetrain inefficiencies are reduced in electric on-road vehicles.

Geared towards model builders and service technicians, the shaft sits at the tensioner pivot and works with the pulley and mount to protect belt alignment under load. As an aftermarket element its priority is mechanical fit and material strength rather than cosmetic upgrades.

Fitting advice: locate the shaft into the tensioner bracket and pulley stack following your kit instructions, check for free pulley rotation and proper belt tracking, and confirm tension over full travel. Refer to the kit manual or vendor for torque guidance and clarification on any small included parts.

This shaft serves as a simple steel replacement for the Medius X26 tensioner assembly, aimed at those who value consistent belt tension and dependable drivetrain operation in electric RC kit projects.
