Core Features

17783N is a WAI aftermarket PMGR (Permanent Magnet Gear Reduction) starter, engineered based on Mitsubishi OE design for Suzuki off-road vehicles and Chevrolet Tracker.

Lightweight PMGR Construction: Equipped with permanent magnet structure and integrated planetary gear set. It delivers stable 1.4kW cranking torque with compact size and high efficiency, perfectly fitting the engine bay of Suzuki compact SUVs.
Side-Mounted Integrated Solenoid: The electromagnetic solenoid controls pinion movement and high-current circuit switching simultaneously. It adopts standard M8 threaded B+ main terminal and 50-type control terminal, fully compatible with original vehicle wiring harness.
8-Tooth Reinforced Floating Pinion: Precision hardened pinion matched with heavy-duty overrunning clutch. It realizes smooth, low-noise meshing with flywheel ring gear and reduces gear wear under frequent cold startups.
2-Hole Standard Mounting Flange: Two threaded fixing holes enable rigid direct bolt-on installation without any modification to the engine block.
Robust Long-Service Design: Anti-corrosion coated motor housing, high-temperature resistant carbon brushes, reinforced armature and durable aluminum gear housing. It withstands vibration and temperature fluctuations for daily commuting and off-road driving.
Wide Cross Reference Compatibility: Direct replacement for multiple Suzuki OEM part numbers and Mitsubishi core codes. New and remanufactured units are widely available in the global auto spare parts market.

Working Principle

This starter converts 12V DC electric energy from vehicle battery into mechanical cranking torque through four continuous stages:

Solenoid Excitation: When the ignition switch is turned to START position, low-current control signal energizes the solenoid coil, generating magnetic force to pull the internal plunger forward.
Pinion Axial Engagement: The plunger pushes the shift fork to slide the 8-tooth pinion outward axially and fully mesh with the engine flywheel ring gear.
Engine Cranking Output: After complete gear engagement, the solenoid closes heavy-duty internal contacts. High current flows into the DC armature motor; rotation torque is amplified by planetary gears to drive the flywheel and crank the gasoline engine for ignition.
Automatic Anti-Reverse Protection: Once the engine starts and rotates faster than the pinion, the built-in overrunning clutch slips to prevent reverse rotation damage to the starter. The solenoid cuts power, the return spring pulls the pinion back to idle position automatically.
