High Grade 42T Center Spur

The XRAY 355054 Center Differential Spur Gear 42T is a purpose-made component for RC drivers who demand precise tooth contact and long service intervals. Built from HUDY steel, it is suitable for replacement or upgrade use in Vintage XB Series centre gearboxes.

Machine Finish for Reliable Mesh

Produced on advanced German machines, the gear is precision ground to promote even contact patterns with differential outdrives. The clear laser "42T" marking aids quick part identification during strip-downs and rebuilds.

Enhanced Core Hardness

Advanced heat treatment enhances material hardness through the core as well as the surface, which cuts down on wear and prolongs usable life compared with standard gears, making it a sound choice for regular running.
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 spur reduce gearbox noise?

Properly set mesh and the precision ground teeth of this gear help reduce noise; ensure backlash is correct and bearings are in good condition for quiet operation.

Should I replace the gear or reheat treat an old one?

Replacing with a new XRAY 355054 is generally quicker and more reliable than attempting to reheat treat worn gears; the new part provides consistent hardness and geometry out of the box.

Any tips for matching this spur to your pinion?

Check tooth counts and use a gear mesh gauge to set a slight clearance for smooth engagement; correct pinion alignment and secure mounting are key to long life.
