Serpent 440112 Rear transmission case for Mini Spyder MT rear drivetrain  [SER440112]

Rear transmission case for Mini Spyder MT

This is a rear transmission case intended as an RC-scale replacement for the Serpent Mini Spyder Monster truck RTR EP (SER440001). It serves as the chassis-mounted housing that locates the rear drivetrain components and supports the spur and pinion alignment in rear assemblies.

Compatibility is stated with the Mini Spyder MT designation in the product name and the SER440001 RTR chassis reference; confirm fit against your chassis before installation. The part replaces a damaged rear case or can be used to refresh an aging drivetrain housing to maintain correct gear mesh and alignment.

Installation notes: remove the existing rear case and transfer original hardware and any bearings into the replacement housing, ensure mating faces are clean, and verify gear alignment under slow manual rotation before reassembly. Avoid over-tightening fasteners to prevent distortion of mounting faces which can cause premature gear wear.

Tuning and service role: this component is primarily a structural part that affects gear alignment and drivetrain stiffness; using a correct-fitting rear case helps ensure consistent gear mesh which supports predictable power delivery and reduces irregular wear during routine use.
