The new Bosch commercial starter features:
• Six-pole field windings for increased power with less sensitivity to low battery charge for more reliable starts.
• A planetary gear reduction system to increase torque and provide faster starts.
• O-rings to increase resistance to dust, dirt, and moisture, thereby increasing life.
• A weight of only 21 lbs., 38-percent lighter than comparable units for easier installation in tight engine compartments.
• A two-stage solenoid that prevents damage to the engine ring gear and extends the life of the starter pinion gear.
• Conical solenoid contacts, dual-composite long-life brushes, and an integral magnetic switch that provide quicker starts and increased durability.
• Exclusive Bosch armature winding technology that provides more copper and increases thermal conductivity, as well as increased resistance to heat for extended life.
