P90 Brass Gear Reducer 3.2:1 Ratio for M12 Steam & IC Engine Models
Hero Section: Tame the Speed, Multiply the Torque
High-speed engines are thrilling, but sometimes you need raw pulling power. The P90 Gear Reducer is the essential upgrade for your M12 Steam or Internal Combustion Engine. Crafted from solid brass with a stunning vintage aesthetic, this miniature gearbox reduces your engine's output speed by a ratio of 3.2:1, instantly multiplying torque. Whether you are powering a heavy model tractor, a slow-moving pump, or simply want to observe the mechanical motion at a more leisurely pace, the P90 adds both functionality and a touch of golden-age industrial beauty to your setup.
Why Choose the P90 Gear Reducer?
- Torque Multiplication (3.2:1): By stepping down the RPMs, this reducer significantly increases the torque output. This allows your compact M12 engine to drive heavier loads or larger propellers that it otherwise couldn't handle directly.
- Exquisite Brass Craftsmanship: Forget plastic or cheap alloys. The P90 features a shell and internal gears machined entirely from high-quality brass. It’s heavy, durable, and develops a beautiful patina over time, perfectly matching the aesthetic of classic steam and vintage gas engines.
- Dual-Pulley Versatility: The output shaft is equipped with two separate pulleys, giving you flexible options for belt drives. You can power multiple accessories simultaneously or choose the pulley size that best fits your transmission needs.
- The Perfect M12 Companion: Designed specifically as an upgrade part for the M12 engine series, it bolts on and integrates seamlessly. It transforms a standalone engine into a capable power unit ready for work.
Technical Highlights: Precision in Miniature
- Smooth Gear Mesh: The internal brass gears are precision-cut to ensure smooth, quiet operation with minimal backlash. The reduction process is efficient, preserving the power of your engine.
- Standard 5mm Shaft: Featuring a robust 5mm output shaft, it is compatible with a wide range of standard model accessories, couplings, and drive wheels.
- Compact Industrial Design: Measuring just 6.8 x 5.8 cm, it packs a heavy-duty mechanism into a footprint that won't overwhelm your model display.

Usage Scenario: The Heavy Lifter
You have your M12 engine running beautifully, but it spins too fast to drive your model water pump. You install the P90 Reducer. You connect the engine flywheel to the input, and the pump to the P90's output pulley. You fire up the engine. The engine revs happily at high RPM, but the pump turns at a steady, powerful, and rhythmic pace. The brass gears hum quietly. You’ve successfully engineered a functional, balanced mechanical system.
