Starter Motor 0K601-18-400: Features, Working Principle & Technical Specifications

The 0K601-18-400 is an OEM Mitsubishi-designed gear reduction starter specially manufactured for Kia light commercial diesel vehicles, including K2700, Bongo and Pregio fitted with 2.7L diesel engines.

1. High-Torque Gear Reduction Construction: Adopts robust planetary gear set and delivers stable 2.2kW cranking power. Sufficient torque overcomes high compression pressure of Korean light-duty diesel engines and ensures reliable cold start under low-temperature conditions.
2. Side-Mounted Integrated Electromagnetic Solenoid: The solenoid assembly is fixed on the side of motor housing. It controls two functions simultaneously: pushing the drive pinion to mesh with flywheel ring gear and switching high-current main circuit. Equipped with standard M8 threaded B+ main power terminal and dedicated 50-type control terminal, perfectly matching original Kia wiring harness.
3. 11-Tooth Reinforced Floating Drive Pinion: Hardened gear teeth matched with heavy-duty overrunning clutch, achieving smooth, low-noise meshing and minimizing gear wear under frequent start-stop cycles for delivery vehicles.
4. 3-Hole Standard Mounting Flange: 88mm centering flange with three fixing holes, enabling rigid direct bolt-on installation without modification to engine block.
5. Heavy-Duty Industrial Grade Durability: Thick cast aluminum gear housing, anti-corrosion coated motor casing, high-temperature resistant carbon brushes and reinforced armature assembly. Able to withstand continuous heavy-load operation, vibration and temperature fluctuation for commercial vans.
6. High Interchangeability: Fully interchangeable with OE counterpart 0K60A-18-400, widely stocked as new and remanufactured units across global auto spare parts market.

This starter converts 12V DC electrical energy from vehicle battery into mechanical cranking torque through four sequential operating phases:

1. Solenoid Excitation: When ignition switch turns to START position, low-current control signal energizes internal solenoid coil, generating magnetic force to pull the metal plunger forward.
2. Pinion Axial Engagement: The plunger drives shift fork to slide the 11-tooth pinion outward axially, forming complete meshing contact with engine flywheel ring gear.
3. Engine Cranking Output: After full gear engagement, solenoid closes heavy-duty internal contact points. High electric current flows into DC armature motor; rotation torque is amplified by planetary reduction gears to drive flywheel and crank the 2.7L diesel engine for ignition.
4. Automatic Anti-Reverse Protection: Once engine ignites and rotates faster than pinion speed, built-in overrunning clutch slips to avoid reverse rotation damaging the starter assembly. The solenoid loses power, return spring pulls pinion back to idle position automatically.

This OEM-spec starter is factory calibrated exclusively for Kia light commercial diesel vehicles. Uniform mounting dimensions and electrical interfaces support direct plug-and-play replacement.

The 2.2kW high torque output satisfies heavy-duty starting demands of commercial delivery vans. Mass stock of new and remanufactured spare parts are available worldwide. Complete cross-reference numbers simplify procurement for auto repair workshops and cross-border auto spare merchants.
