How hard is it to fit this spur to my model?

Fitting is straightforward for most kits that use 48-pitch spurs: remove the old gear, align the new spur and pinion, then check mesh and secure the gear as per chassis instructions.

Will it make my drivetrain noisier?

A correct gear mesh results in quiet operation. Noise usually comes from poor mesh or damaged teeth, so set the mesh carefully to keep operation smooth and quiet.

When should I replace the spur gear?

Replace the spur if you notice chipped teeth, excessive play, or consistent slipping. Regular checks after heavy runs help avoid mid-session failures.
