The crankshaft stud is one of the most important internal components in an engine. It is used to secure and support the crankshaft within the engine block, allowing it to rotate smoothly while reducing friction between it and the engine's metal frame.

✅ Main function:
- Installing the crankshaft inside the block:
- Maintains balance and alignment of the shaft while rotating at high speeds.
- Facilitating rotational movement:
- Reduces friction and allows the crank to rotate smoothly to transmit the motion of the pistons.
- High pressure tolerance:
- Absorbs the thrust and pressure forces generated by the combustion of fuel inside the combustion chambers.
⚙️ Mechanism of action:
- The spike is usually in the form of two metal halves that fit inside the crankshaft.
- It is charged by oil pressure through passages inside the crankshaft to provide constant lubrication during operation.
- Varies depending on shaft dimensions or wear condition (sizes: STD - 0.25 - 0.50...).
