Differential bevel gear set for MP11
The Kyosho IF715 Diff. Bevel Gear Set is an RC-scale replacement gear set intended for the Kyosho MP11 platform, matching the 10T/20T tooth configuration noted in the original part name. This article focuses on practical compatibility notes, installation considerations, and how the gear set affects drivetrain behavior during setup and tuning sessions.
Compatibility and role: this bevel gear set is explicitly identified for use with the MP11 chassis, serving as a direct spare for worn or damaged bevel gears in the rear differential assembly. In use it defines the meshing geometry inside the differential, which influences backlash, torque transfer characteristics, and the feel of the drivetrain under acceleration and deceleration in RC scale operation.
Installation guidance: inspect the mating faces and the corresponding differential carrier before fitting, clean old grease and debris, and verify concentric seating on the diff cross and side gears. Fit the 10T and 20T gears so teeth mesh smoothly without binding, check for free rotation across the full range of suspension travel, and re-check pinion alignment if the differential was disassembled. Use proper thread locking where the chassis manual specifies and run-in at low load to confirm correct engagement.
Tuning considerations: swapping to a fresh bevel gear set restores predictable backlash and reduces slop from worn teeth, which can improve consistency in corner exit and traction modulation. When adjusting diff tightness, small changes in gear mesh and shimming can affect drivability; make incremental changes and test on the same surface to evaluate performance differences. Bearings and diff oil viscosity interact with gear condition, so consider those items during a full drivetrain tune.
For MP11 owners the IF715 set provides a straightforward pathway to restore differential function, facilitating reliable setup and repeatable tuning outcomes without altering core chassis geometry.
