Replacement bevel gears for the MP11 differential
The Kyosho IF715 Diff. Bevel Gear Set is a direct replacement pack for the Kyosho MP11 platform, supplied in the 10T/20T tooth pairing shown in the original designation. The following notes concentrate on fitment, straightforward fitting tips, and how fresh bevel gears change drivetrain behavior during setup and tuning.
Compatibility and role: The IF715 set is listed specifically for the MP11 chassis and serves as a spare for worn or damaged bevel gears in the rear differential assembly. Installed gears establish the internal mesh geometry, which affects backlash, torque transfer characteristics, and the drivetrain feel under acceleration and braking in scale RC operation.
Installation guidance: Before fitting, inspect mating faces and the differential carrier, remove old grease and debris, and confirm concentric seating on the diff cross and side gears. Fit the 10T and 20T gears so teeth mesh smoothly without binding, verify free rotation through the full range of suspension travel, and re-check pinion alignment if the diff was taken apart. Apply thread locking where the chassis manual recommends and perform a low-load run-in to confirm correct engagement.
Tuning considerations: Installing a new bevel gear set restores predictable backlash and reduces slop from worn teeth, which can improve corner exit consistency and traction modulation. Small adjustments to diff tightness, gear mesh, or shimming will affect drivability, so make incremental changes and test on the same surface to judge differences. Bearings and diff oil viscosity interact with gear condition, so include those items when carrying out a full drivetrain tune.
For MP11 owners, the IF715 set provides a clear route to restore differential function and regain consistent setup results without changing core chassis geometry.
