Upgrade for X12: DP64 93T Machine Cut Spur Gear - Yokomo YOKR126493S  [YOKR126493S]

93T DP64 Machine-Cut Spur for X12 Applications

The DP64 93-tooth machine-cut spur from Yokomo is an upgrade for the X12 chassis, offering a larger tooth count choice for those tuning gear ratios. Using a 93T spur shifts the balance toward greater top speed potential and more granular gear steps, which may reduce low-end punch relative to smaller spurs.

Machine-cut construction ensures a consistent tooth geometry that helps sustain stable mesh with the pinion gear, leading to cleaner engagement under load compared with rougher-cut spurs. This advantage shows during extended runs or when swapping pinion sizes frequently.

Installation guidance: secure the spur in the gearbox carrier following X12 assembly practice, verify centreing and axial clearance, and set motor pinion mesh while rotating the drivetrain to ensure smooth operation. Confirm the spur clears the chassis and nearby parts before tightening hardware fully.

Role in tuning and upkeep: install a 93T spur to dial in top-end speed and refine ratio increments when experimenting with pinion choices. Keep the gear clean of debris, inspect teeth for damage, and maintain bearings and pinion condition to protect mesh accuracy.
