The Yokomo PG-6426A Precision Hard Coated Aluminum Pinion Gear is a key upgrade for hobbyists aiming to sharpen gear engagement and reduce weight. Machined from lightweight aluminum, this 26-tooth pinion prioritises accuracy and long service life.
When matching parts, correct pitch is essential. The PG-6426A meshes cleanly with 64 pitch spur gears to deliver smooth torque transfer and minimise premature wear, making it a practical choice for track or club racing setups.
Aluminium gives a strong but light option for high-rev applications where reducing rotating mass matters. The hard coating increases surface resistance to abrasion, helping the gear hold up under extended running.
For best results, check that the pinion is seated squarely on the motor shaft and that backlash is set correctly with the spur gear. Periodic checks of set screws and mesh will keep performance consistent.
