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 do I check gear mesh after fitting the S4-503D16A?

Fit the S4-503D16A with the matching ring gear and adjust the gearbox to produce a small, even backlash. Rotate the drivetrain to confirm smooth contact across the tooth face.

What maintenance keeps this gear lasting longer?

Regular inspection for tooth wear, correct gear mesh, and keeping bearings in good condition will extend service life. Replace if chipped or excessively worn.
