This 28-tooth MOD1 pinion has a 5mm bore and uses an oversized M5 set screw in place of the usual smaller grub screw, so it bites harder into the motor shaft and stays put.\u003c\/p\u003e\n\u003cp\u003eThe line runs from 11T all the way to 30T, so you can land on exactly the gear ratio your track, motor and battery want. A tooth either way is the fastest way to trade punch for top speed, or to pull motor temps back down.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e28 tooth MOD1 (1.0 module) pinion gear\u003c\/li\u003e\n\u003cli\u003e5mm bore to suit standard 1\/8 scale electric motor shafts\u003c\/li\u003e\n\u003cli\u003eOversized M5 set screw for a more secure clamp\u003c\/li\u003e\n\u003cli\u003eSteel construction for life behind high-torque brushless power\u003c\/li\u003e\n\u003cli\u003eSold in single-tooth steps from 11T to 30T\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePerformance Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSingle-tooth steps let you fine-tune acceleration against top speed\u003c\/li\u003e\n\u003cli\u003eLarger M5 screw resists stripping and stops the pinion slipping on the shaft\u003c\/li\u003e\n\u003cli\u003eAccurate MOD1 tooth form keeps the mesh smooth and quiet\u003c\/li\u003e\n\u003cli\u003eGear down to drop motor temps, up for speed on open layouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eUsage Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eConfirm your motor has a 5mm shaft before fitting\u003c\/li\u003e\n\u003cli\u003ePair with a MOD1 spur only - never mix with 48 pitch, 32 pitch or MOD1.5\u003c\/li\u003e\n\u003cli\u003eSet the mesh with slight backlash and re-check after the first run\u003c\/li\u003e\n\u003cli\u003eSeat the M5 screw on the shaft flat with a properly fitting hex driver\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Tekno RC\u003c\/li\u003e\n\u003cli\u003eItem No.: TKR4188\u003c\/li\u003e\n\u003cli\u003eType: Pinion gear\u003c\/li\u003e\n\u003cli\u003eTooth Count: 28T\u003c\/li\u003e\n\u003cli\u003eModule\/Pitch: MOD1 (1.0 module)\u003c\/li\u003e\n\u003cli\u003eBore: 5mm\u003c\/li\u003e\n\u003cli\u003eSet Screw: M5\u003c\/li\u003e\n\u003cli\u003eMaterial: Steel\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: Taiwan\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e(1) Tekno RC 28T MOD1 M5 pinion gear\u003c\/li\u003e\n\u003cli\u003e(1) M5 set screw\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp data-fitment-audit=\"true\"\u003e\u003cstrong\u003eCompatible RC vehicles:\u003c\/strong\u003e Fits 1\/8 scale electric buggies, truggies and short course trucks, and any other RC vehicle, running a MOD1 (1.0 module) pinion on a 5mm motor shaft.
