Reduced Mass and Accuracy with XRAY 305987

The XRAY 305987 Narrow Pinion Gear is crafted from aircraft duraluminum to lower rotating weight while retaining strength. It achieves around a 25% weight reduction over standard pinions and its narrow 1.5mm slimmer profile helps reduce rotational drag for crisper acceleration.

Craftsmanship and Surface Hardening

Produced on a specially adapted gear machine, every pinion is made to tight tolerances for excellent concentricity. Chamfered edges, a run-in period, and a hardcoat finish are applied to extend life and preserve smooth, low-noise operation when used with XRAY spur gears.

Compatibility, Setup and Handling

The XRAY 305987 is compatible with many spur gear choices and integrates cleanly with XRAY gear sets for quiet running. It is suitable for both competitive upgrades and regular maintenance, delivering reliable performance once correctly installed.
Remark :
Due to limited stock availability, please notice that some XRAY 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 this pinion work on vintage 1/10 models?

It may fit many older 1/10 models but verify shaft diameter and spline compatibility before purchasing to avoid fitment issues.

How do I check the pinion's concentricity?

Mount the pinion and spin the shaft by hand while observing runout; minimal wobble indicates correct concentricity. A dial indicator gives a precise measurement if available.

Should I change spur gear material when upgrading to this pinion?

Not necessarily; the XRAY 305987 pairs well with quality spur gears, but matching durability and finish between pinion and spur can improve longevity and noise characteristics.

Is the hardcoat finish repairable if damaged?

Minor surface marks can be smoothed, but significant coating damage usually requires replacement to restore optimal wear resistance and gear engagement.
