Yokomo SG-6490 64-Pitch 90T Precision Spur Gear  [SG-6490]

64-Pitch Spur Gear - 90 Teeth

This spur gear is an RC-scale replacement part produced for general drivetrain service, with 90 teeth cut to a 64 pitch specification. The accurate machining reduces backlash and improves how the spur interacts with a matched pinion, helping the drivetrain run more smoothly under normal electric model loads.

When installing this spur, pair it with a 64 pitch pinion to achieve correct tooth engagement. Setup emphasis should be on proper mesh and bearing alignment rather than swapping materials, since the component's purpose is to supply consistent tooth form for predictable tuning and power transfer inside the gearbox or chassis layout.
