The Main Motor Metal Gear is a premium-quality compatible replacement designed for Samsung ML-1640, ML-1660, and ML-1666 monochrome laser printers. This gear is installed on the main drive motor shaft and transfers rotational power to the printer’s gear train, enabling smooth operation of the paper feed mechanism, toner cartridge, developer unit, and fuser assembly.
Continuous printing, excessive mechanical load, paper jams, or normal wear can cause the metal gear to wear, crack, or become damaged. A faulty main motor gear may result in gear slipping, loud grinding noise, paper feed failure, engine errors, or complete printer malfunction.
Replacing the damaged Main Motor Metal Gear restores smooth power transmission, proper gear synchronization, and reliable printer operation without replacing the complete motor assembly.
Manufactured from high-strength hardened metal, this gear offers excellent wear resistance, precision machining, and long service life. It is an ideal spare part for printer technicians, service centers, and printer refurbishment professionals.

Why Replace the Main Motor Gear?
The Main Motor Gear transfers rotational power from the main motor to the printer’s drive system. Over time, continuous operation, paper jams, or excessive load can wear down the gear teeth or cause mechanical damage.
Replacing only the main motor gear is a cost-effective solution that restores smooth printer operation without replacing the complete motor assembly.
