This is the rear drive belt intended for use on BD7-2015 scale touring cars when a forward motor conversion is installed. It serves as the replacement belt that routes power to the rear drivetrain once the motor location is converted to the front of the chassis.
Compatibility is focused on the BD7-2015 platform variants listed for this part, specifically MRTC-BD715B, MRTC-BD715O, and MRTC-BD715S. Confirm your chassis code matches one of these before fitting the belt.
Installation notes: fit the belt following the existing pulley path on the converted drivetrain, ensure pulleys are aligned, and set belt tension to remove slack without causing excessive drag. Check belt seating on each pulley and inspect for signs of uneven wear after the first few runs.
Tuning role: the belt links motor output to the rear geartrain and affects drivetrain responsiveness and smoothness. Proper tension and pulley alignment reduce slop and drivetrain losses, while a worn or stretched belt can introduce play and inconsistent power delivery. Routine inspection and replacement when wear appears keep handling consistent.
