Kubota U30-5 Starter Motor (8T/9T Pinion Teeth)

This high-power 12V starter motor is engineered specifically for Kubota U30-5 excavators. As a reliable aftermarket replacement, its electrical interfaces and mounting flanges are fully compatible with OEM 17123-63016 and 17123-63010. To accurately match various regional D1703 engine configurations, we offer both 8-tooth (8T) and 9-tooth (9T) pinion teeth specifications. The assembly features a high-strength 20CrMo alloy steel pinion gear treated with high-frequency surface quenching. Combined with industrial-grade high-conductivity copper windings, it ensures exceptional impact resistance and stable cold-start torque in harsh environments, making it an optimal solution for B2B heavy machinery maintenance.
