Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How does an idler gear influence drivetrain smoothness?

An idler gear sets the spacing and alignment between drive gears, helping to maintain consistent mesh so power is transferred without binding or uneven wear.

Will the ZB-503I20 fit other Yokomo chassis?

This part is made for the YZ-834B layout. It may fit other models with the same gear spacing but you should compare dimensions before attempting to install.

Any tips for installing and maintaining this gear?

Keep the gear free of debris, check mesh with the spur and pinion, and use a light gear oil or grease appropriate for your drivetrain to extend service life.
