Precision Composite Spur for Smooth Drive

The XRAY 364981 Composite Center Differential Spur Gear uses an 81-tooth configuration to maintain even torque flow through the centre diff. Made from a high-performance composite, it offers good resistance to wear while keeping the rotating assembly light. The tooth count is marked for quick recognition when servicing or adjusting gear ratios.
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.

How do I match pinion to this 81T spur?

Select a pinion that gives the desired ratio while allowing correct mesh. Trial fit with shims and check tooth engagement across the face to avoid binding.

What signs show the composite spur needs replacing?

Replace the spur if you notice chipped teeth, uneven wear patterns, persistent whining or slipping under load. These indicate the part can no longer maintain smooth gear mesh.

Any setup tips for best longevity?

Keep gear mesh tight but free, maintain clean bearings, and avoid prolonged overheating from excessive motor load to maximise service life.
