The Serpent 402201 belt tensioner shaft is a steel replacement part intended for use in belt-driven Serpent Medius X26 kits. Its purpose is to set and preserve belt tension inside the tensioner unit so the belt runs true and slack-related drivetrain loss is minimised in electric on-road applications.
Targeted at hobbyists and workshop technicians, this shaft fills the tensioner pivot position in the chassis and works with the pulley and mount to maintain belt alignment under load. As an aftermarket component it focuses on mechanical strength and correct fit rather than cosmetic finish.
Installation guidance: place the shaft into the tensioner bracket and pulley assembly following your kit's build order, check pulley freedom and belt tracking, then verify tension over full travel. Treat this as a kit replacement part and consult your manual or vendor for any torque or small hardware details.
A straightforward steel swap for the Medius X26 tensioner, aimed at constructors and tuners who want reliable belt tension and drivetrain consistency in electric RC kit setups.
