Hitachi Washing Machine Gearbox, Twin Tub
The washing machine gearbox, which technicians call the transmission or gear case, is the mechanical unit that transfers the motor’s drive to the wash tub, converting fast rotation into the slow, powerful movement that drives the agitator.

Frequently Asked Questions
Q1. How much is a Hitachi washing machine gearbox?
It is SAR 150 including VAT at Cool.sa, and it is in stock.
Q2. Is this a genuine Hitachi part?
No. This is a compatible replacement manufactured to match the dimensions and function of the original gearbox. It is often the only option available for older models whose genuine parts are no longer produced.
Q3. Does it fit any Hitachi washing machine?
Not necessarily. Measurements are the fitment reference for compatible parts, not the model number. Send us the bolt centre distance, shaft length, pulley diameter and body height and we will confirm.
Q4. The motor runs but the tub does not turn, has the gearbox failed?
Not necessarily. Check the belt and brake lever first, as both produce the same symptom and cost a fraction of a gearbox.
Q5. How do I know it is the gearbox and not the belt?
Disconnect power and turn the agitator by hand. If it spins completely freely with no resistance, the gearbox has lost drive. If it has normal resistance, check the belt, brake and motor.
