5. Operating Instructions
The Sparkleiot 6-Speed Gearbox with V16 Engine Model is designed to demonstrate the mechanical principles of a multi-speed transmission and a V-configuration engine. Once assembled, the model can be operated manually or integrated with compatible MOC Power Functions.
5.1 Manual Operation
The gearbox features a shifting mechanism that allows you to manually change between its 6 speeds. Locate the gear selector lever on the top of the gearbox. Moving this lever will engage different gear ratios, which can be observed through the exposed gears.
The V16 engine model includes pistons that will move in conjunction with the rotation of the crankshaft. You can manually rotate the input shaft of the engine or gearbox to observe the internal workings.
5.2 Integration with Power Functions
This model is designed to be compatible with MOC Power Functions (sold separately). A power motor can be connected to the input shaft of the gearbox or engine to automate its operation.
To connect a power motor:
- Identify the designated connection points for a power motor on the model.
- Securely attach your compatible power motor to these points.
- Ensure the motor is correctly aligned to drive the input shaft.
- Activate the power motor to observe the gearbox shifting and engine pistons moving.
