Our Premium Heavy‑Duty 24V 5.5kW Starter Motor (Part Number: 22851149 / VOE22851149) is a high‑torque cranking assembly designed for heavy‑duty VOLVO diesel engines in cold‑climate and high‑compression operating conditions. Optimized for VOLVO D6D, D7D and D7E engines, this starter features a 12‑tooth clockwise‑rotation pinion gear. It engages reliably with the flywheel ring gear to provide fast engine startup for construction and mining machinery under harsh working environments.
High‑Power Pure‑Copper Field Coils: Heavy‑gauge pure copper windings deliver strong cranking torque while effectively dissipating heat during extended starting cycles.
Heavy‑Duty Overrunning Sprag Clutch: Precision internal clutch disengages automatically after engine ignition, preventing armature damage caused by over‑speeding.
Sealed Weather‑Resistant Solenoid: Fully sealed magnetic switch resists moisture, mud splash and quarry dust, avoiding starting‑circuit failure and click‑only faults.
Precision Reinforced Bearing Assembly: Heavy‑duty needle and ball bearings absorb engagement‑impact vibration, preventing housing cracking and extending service life.
