This Delrin main gear serves as a direct replacement for Kyosho Inferno MP7.5 drivers needing a spare 46-tooth spur for routine service or setup swaps. The component is chosen for Delrin's steady wear profile and consistent meshing, supplied as 1 pcs to match the existing gearbox configuration.
Installation involves swapping the spur assembly inside the gearbox; set gear mesh and check backlash during reassembly and roll the drivetrain by hand to ensure smooth engagement before applying power. In tuning terms, this gear helps maintain dependable drivetrain behaviour when you change pinion sizes or adjust spur positioning.
