P90 Brass Gear Reducer 3.2:1 Ratio Gearbox for M12 Steam & IC Engine Models
Hero Section: Tame the Speed, Master the Torque
High RPMs are thrilling, but true mechanical work requires torque. The P90 Gear Reducer is the essential upgrade that transforms your M12 Steam or Internal Combustion Engine from a high-speed spinner into a heavy-duty workhorse. Crafted entirely from solid brass, this miniature gearbox reduces speed by a ratio of 3.2:1, instantly multiplying the pulling power. With its vintage industrial aesthetic and precision engineering, it’s not just a functional component—it’s a golden jewel that elevates the visual appeal of your entire mechanical setup.
Why Choose the P90 Gear Reducer?
- Torque Multiplication (3.2:1): By stepping down the engine speed, this reducer significantly increases torque. This allows your compact engine to drive heavier loads, such as model tractors, water pumps, or generators, which it couldn't handle with direct drive.
- Solid Brass Craftsmanship: Forget plastic or cheap plating. The P90 features a shell and internal gears machined from high-quality brass. It feels heavy in the hand, offers excellent durability, and develops a stunning patina over time that complements vintage-style engines perfectly.
- Dual-Pulley Versatility: The output shaft is equipped with two separate pulleys. This smart design gives you flexibility in belt alignment and allows you to drive multiple accessories simultaneously or choose the best ratio for your specific application.
- The Perfect M12 Upgrade: While compatible with various custom builds, it is designed as the ultimate companion for the M12 engine series. It enriches the gameplay by adding mechanical complexity and expanding the range of experiments you can perform.
Technical Highlights: Precision in Miniature
- Smooth Transmission: The internal brass gears are precision-cut to ensure smooth meshing and quiet operation. The reduction process is efficient, minimizing friction loss.
- Standard 5mm Shaft: Featuring a robust 5mm output shaft, the reducer is compatible with a vast array of standard model couplings, drive wheels, and accessories, making integration easy.
- Compact Industrial Design: Measuring just 6.8 x 5.8 cm, it packs a heavy-duty mechanism into a compact footprint that enhances, rather than overwhelms, your model display.

Usage Scenario: The Power Plant
You have your M12 engine running smoothly, but it spins too fast to turn your model Ferris wheel or pump. You bolt on the P90 Reducer. Connecting the engine flywheel to the input, you watch as the frantic speed of the engine is converted into a slow, powerful, rhythmic rotation at the output. The brass gears hum quietly, and your model comes to life with a new sense of purpose and realism.
