The SM 5920A is an industrial-grade, complete Self Starter Motor Assembly engineered for high-torque applications in Deutz engines and aerial work platforms. While sharing the same 2.5kW power profile as the SM 5920, this "A" variant features an 11-teeth (11T) pinion gear. Utilizing a robust Bosch Type (B.TYPE) architecture, it is built to handle the heavy cranking loads of the Deutz 223 and 1011/2011 series engines used in global boom lift brands.
