Tamiya M05 48Pitch 33T Spur Gear for Tuning by Factory Pro O-AP0002  [FP-O-AP0002]

Overview and fitment

This Factory Pro O-AP0002 spur gear is an aftermarket replacement made for Tamiya M-series small touring chassis. The 33-tooth 48Pitch profile matches standard 48Pitch pinions and spurs and is intended to change final drive ratio and mesh behavior in tight gearbox layouts.

Compatibility targets the M05 family and closely related M06/M07/M08 variants that share the 48Pitch standard; confirm gearbox clearance and the pinion tooth count on your car before fitting. Treat this item as a direct spur replacement rather than a multi-piece service assembly.

Installation tips: slide the spur onto the gearbox hub, set backlash and axial play, and check for smooth engagement through steering and suspension travel. Run short, low-load test sessions to spot any binding or premature wear and correct mesh before longer runs.

Tuning notes: swapping in a 33T spur alters the overall ratio compared with other spur sizes, which changes acceleration versus top speed. Combine spur changes with pinion swaps and motor/ESC adjustments as part of an incremental tuning plan for track or club running.
