Tamiya 53407 0.4 Aluminum Pinion Gear Set 38T/39T OP-407 - Precision Pinions  [53407]

Fine-Tune Your Drive Ratio with Tamiya Pinions

The Tamiya 53407 Aluminum Pinion Gear Set is ideal for hobbyists wanting to tweak performance. The pair of 38-tooth and 39-tooth pinions lets you change gear ratios to favour acceleration or top speed. Machined from aluminium, these pinions are built to balance light weight with reliable strength for fast runs.

Core Characteristics of the Pinion Set

• Material: Constructed from lightweight aluminium to reduce rotating mass while keeping strength.
• Compatibility: Works well with a range of Tamiya chassis, including TA04 and TB-01, and any chassis that accepts 0.4 M pitch pinions.
• Pitch: Uses a 0.4 M (48P metric) pitch for accurate meshing with matching spur gears.

Fitting and Mesh Advice

Fitting the Tamiya pinions is straightforward. Ensure the motor is firmly mounted before sliding on the pinion, then secure it using the supplied grub screws and allen wrench. Set a small clearance in the gear mesh so the pinion and spur run smoothly without binding, and inspect the mesh regularly for wear.
