Duet (Feb, 2017) Crank Case Right Engine Hero Genuine Parts

Functions

The engine crankcase in a scooter, particularly the right crankcase half, houses several critical components and performs key functions related to the operation of the engine. Here’s what it typically involves:

Components Found in the Right Crankcase:

1. Crankshaft and Bearings: The crankshaft is partly housed in the crankcase, where it converts the linear motion of the piston into rotational motion. Bearings support the crankshaft’s rotation.
2. Transmission Components: In some scooter models, the right crankcase may contain parts of the transmission, such as gears or the variator, especially in CVT (Continuously Variable Transmission) systems.
3. Oil Pump: Some models have an oil pump housed in the crankcase, which is responsible for circulating oil throughout the engine.
4. Kickstart Mechanism: In scooters equipped with a kickstart, parts of this mechanism may be housed in the right side of the crankcase.
5. Cooling System Components: If the engine is liquid-cooled, part of the cooling system like water pump drives might be integrated into this section.

Key Functions:

• Sealing the Engine: The crankcase seals the lower part of the engine, preventing oil leakage and contaminants from entering the engine.
• Housing the Crankshaft: It supports the crankshaft’s rotation and is designed to manage the forces created by the engine’s operation.
• Lubrication: It typically has an oil reservoir or passages to ensure that the engine’s moving parts are properly lubricated.

The right crankcase also plays an important role in maintaining engine balance and ensuring smooth operation by securing engine components in place.
