Yamaha RMAX Type II G starter. Short version.
12V, 1.3kW, ten teeth, counter-clockwise. Five numbers. Four have to match the old motor.
Zinc-plated barrel, cast aluminium nose. Two bolt holes, 8 mm, pilot spigot to centre it. Solenoid across the top, stud under a rubber boot. About 1.9 kg.
Rotation. This one turns counter-clockwise. Yamaha used both directions across the unmanned helicopter line. Same flange, opposite spin. Fit the wrong one and the pinion spins free, the sprag never grabs, the engine never cranks.
Fitting. Negative cable off. Two flange bolts out, main stud off, spade off. Both motors on the bench. Flange spacing, tooth count, terminal position. Pinion out by hand. Mesh. Torque. One crank with the ignition off.
Faults. Slow crank plus a good battery: cable or ground. One click: solenoid or relay. Spins and no crank: pinion or sprag. Bench-test the old unit. Half the returns were never the starter.
Packing. One piece, neutral carton, 22x16x14 cm, 1.9 kg. Ningbo or Shanghai, three weeks. One-piece samples fine. Six-month warranty.
