Precision Machined Aluminium Idler for YD-2 Chassis

The Yokomo Y2-503IAA aluminium idler gear is manufactured to tighten gear mesh and resist wear on YD-2 chassis. Its precise machining and hard coat surface protect the gear profile, helping to preserve drivetrain geometry over many running sessions. This makes it a sensible upgrade for those wanting more consistent handling lap after lap.

Suitability and Benefits

Compatible with a range of YD-2 models, this idler is a practical choice for hobbyists who rotate parts between cars. The rigid aluminium body reduces drivetrain play and contributes to a more reliable transfer of power, which can improve corner entry stability and throttle control.
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.

Will the Y2-503IAA need special tools to fit?

Fitting usually requires standard hobby tools and a torque check. Ensure fasteners are secure and that the idler turns freely without binding.

How should I check gear mesh after installation?

Set a slight backlash and rotate the drivetrain to inspect contact across the tooth face. Make small adjustments with shims or motor mount position to achieve even contact.

Are there recommended lubricants for the idler?

Use a light gear grease or silicone-based lubricant on the mating surfaces to reduce friction without attracting excessive dirt.
