Serpent 440112 Replacement Rear Case for Mini Spyder MT (SER440001)  [SER440112]

Rear case description and purpose

This rear transmission case is supplied as a replacement for the Serpent Mini Spyder Monster truck RTR EP (SER440001). It secures to the chassis and positions rear drivetrain components to ensure correct spur and pinion engagement within the rear assembly.

The part is identified with the Mini Spyder MT name and the SER440001 RTR chassis reference; always confirm compatibility with your chassis before fitting. It is intended to replace a damaged rear case or refresh an older housing to restore proper gear mesh and alignment.

Assembly guidance: remove the existing rear case and move original fasteners and bearings into the replacement unit, ensure mating surfaces are clean, and check gear alignment by rotating the drivetrain slowly before completing assembly. Avoid over-tightening screws to prevent distortion of faces that can lead to premature gear wear.

Compatibility considerations: this structural component impacts gear alignment and drivetrain stiffness. A correct rear case keeps gear mesh consistent, helping to prevent irregular wear and supporting reliable power transfer.
