MP11 differential bevel gear guide
The Kyosho IF715 Diff. Bevel Gear Set provides replacement bevel gears for the Kyosho MP11 platform and keeps the 10T/20T tooth configuration indicated in the item code. The following sections outline fit notes, recommended fitting checks, and the practical impact of renewed bevel gears on drivetrain behavior during setup and use.
Compatibility and role: This bevel gear set is identified for use on the MP11 chassis as a direct spare for worn or failed rear differential bevels. When installed the gears establish the meshing geometry inside the diff and thus influence backlash, torque transfer characteristics, and the drivetrain response during acceleration and deceleration in scale RC running.
Installation guidance: Prior to fitting, inspect the mating faces and differential carrier, clean away old grease and debris, and verify that the diff cross and side gears seat concentrically. Fit the 10T and 20T gears ensuring smooth tooth engagement without binding, check for free rotation across the suspension travel, and re-check pinion and spur alignment if the diff was dismantled. Use thread lock where specified by the chassis manual and perform a cautious low-load run-in to confirm correct engagement.
Tuning considerations: Installing a fresh bevel gear set restores consistent backlash and reduces play from worn teeth, which can improve repeatability in corner exits and traction modulation. Small changes in diff tightness, gear mesh, or shimming can alter drivability, so make measured adjustments and test to evaluate effects. Also consider bearing condition and diff oil viscosity as part of a complete drivetrain tune.
For those running the MP11, the IF715 set is a direct solution to regain reliable differential performance and predictable tuning outcomes.
