Replacement spur gear for LAZER ZX7.5

This Kyosho LA427-76 spur gear is an RC-scale replacement part specified as 48P with 76 teeth, intended for use with LAZER ZX7.5 compatible setups. The note covers fitment, drivetrain role, and practical guidance for installation and tuning while avoiding unverified claims.

A 76-tooth spur alters the overall gear ratio and mesh behavior. Installers should verify pinion-to-spur engagement and axial alignment to prevent premature wear; correct mesh and secure fastening are the main factors affecting noise and efficiency.

When fitting this spur gear: confirm shaft fit and that the pinion gear matches 48-pitch specifications, check the gearbox still has proper bearing support, and inspect nearby parts like the gearbox housing and any shims used to set mesh. Small adjustments to mesh and shim thickness will produce predictable changes in acceleration and top speed.

Maintenance advice: inspect teeth for chipping or uneven wear, keep gear faces free of debris, and ensure any set screws or fasteners are torqued appropriately for your chassis to avoid slippage during use.
Remark :
Due to limited stock availability, please notice that some Kyosho 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.

What does the 48P-76T designation mean for this gear?

48P denotes the 48 pitch tooth spacing standard and 76T is the tooth count. Together they define the gear ratio and ensure the correct mesh with matching 48-pitch pinions.

Can I use Kyosho LA427-76 on a LAZER ZX7.5?

The part is identified for LAZER ZX7.5 use; fit it where the chassis calls for a 48P spur of this tooth count and confirm pinion compatibility before running.

How do I set mesh for quieter operation?

Set a small, even gap across the tooth faces, check for endplay on the shaft, confirm bearing support, and tighten set screws to prevent movement under load.

What wear signs mean the spur needs replacing?

Replace the spur if you find chipped or deformed teeth, pronounced uneven wear, increased drivetrain noise, or slipping when the model is under load.
