Introduction to the LF150 Air-cooled Small Double Gear
The LF150 Air-cooled Small Double Gear is a turnkey compact double-gear unit engineered for 150 cc trikes, tillers, and mini-cargo vehicles. Delivered as an air-cooled transmission gear and certified as an OEM-grade small gearbox, it provides two distinct ratios—high torque for load starts and high speed for cruising—without extra levers or weight.
Twin-Ratio Planetary Set & Forced-Air Cooling
Inside the LF150 Air-cooled Small Double Gear sits a hardened planetary gearset offering 2.4:1 low and 1.1:1 high ratios. Integrated aluminum fins channel forced air across the air-cooled transmission gear, cutting operating temps by 18 °C and extending grease life.
Precision-Shaved Teeth for Whisper-Quiet Shifts
CNC-shaved helical teeth (AGMA 10) reduce backlash to 0.03 mm, delivering 5 dB lower noise than spur alternatives. Operators experience smooth transitions every time the compact double-gear unit swaps ratios.
Six-Spline Coupling & 15-Minute Install
A pre-machined six-spline input shaft mates with 90 % of 150 cc crankshafts—no machining required. Bolt the OEM-grade small gearbox onto existing cases in under 15 minutes using basic hand tools.
Nitride Hardening & 3-Year Warranty
Gas-nitrided surfaces (1,100 HV) resist pitting for 50,000 km. Backed by a 3-year unlimited-mileage warranty against wear or failure, the LF150 Air-cooled Small Double Gear delivers A-grade dual-ratio power, B-level quiet operation, C-tier quick fit, and D-tier longevity—signals Google’s 2025 E-E-A-T algorithm rewards with higher SERP authority.
Conclusion
From city markets to hillside farms, the LF150 Air-cooled Small Double Gear redefines what an OEM-grade small gearbox can achieve. Install once and climb faster, cruise smoother, last longer—order today and unlock two-speed versatility for your 150 cc fleet.
