Race-orientated POM idler for SAKURA FF EVO

The 3Racing SAK-F84 17T POM idler is manufactured for the KIT-FFEVO platform with material selection optimised for low friction and repeatable contact patterns. Its moulded profile aids predictable engagement during competitive running.

Technical 17T profile and material choice

The 17-tooth geometry is chosen to balance torque transmission and rotational inertia. POM provides solid wear resistance and consistent coefficient of friction, helping maintain stable mesh under varying loads and temperatures.

Integration and setup notes for FFEVO

Designed for direct fitment into the FFEVO idler station, the SAK-F84 requires conventional mesh and alignment checks. For competitive setups, verify backlash under load, use minimal plastic-safe lubricant, and inspect for wear patterns after initial break-in runs.

What mesh tolerance is recommended for race setups?

Aim for a small, even backlash that avoids binding while keeping contact area centred on the tooth flank. Check mesh at race temperature to compensate for thermal expansion.

Does material choice affect tuning options?

Yes. POM gives predictable friction and wear characteristics, allowing tighter setup windows and consistent lap times compared to softer plastics.

How should I monitor wear during a meet?

Inspect tooth profiles between heats, look for asymmetrical wear or glazing, and rotate spares to maintain consistent behaviour. Replace if you detect uneven contact or tooth damage.
