Main crankshaft bearing set Standard. Porsche 356A / 356B ❭ 54610190100
- Porsche 356A 1955-59
- Porsche 356B 1959-63
The OE Match Main Crankshaft Bearing Set, Standard is a premium-quality replacement engine bearing kit designed to support the crankshaft and maintain precise rotational alignment in compatible Porsche engines. Manufactured to OE specifications for fit, material quality and durability, this standard-size main bearing set restores the correct bearing clearances between the crankshaft and engine block, ensuring optimum oil pressure, smooth crankshaft rotation and long-term engine reliability.
Fits:
- Porsche 356A 1955-59
- Porsche 356B 1959-63
Diagram Ref No 13
Manufactured from premium tri-metal bearing materials with a precision-machined bearing surface, each bearing shell is engineered to provide exceptional load-carrying capacity, low friction characteristics and excellent resistance to wear under demanding operating conditions. Designed for direct OE-style installation, this standard-size bearing set is ideal for engine rebuilds where the crankshaft journals remain within original factory specifications.
What This Product Does:
- Supports the crankshaft within the engine block.
- Maintains precise crankshaft bearing clearances.
- Allows smooth, low-friction crankshaft rotation.
- Maintains correct engine oil pressure.
- Reduces friction and wear between the crankshaft and engine block.
- Supports reliable engine lubrication.
- Restores factory engine operating tolerances.
- Forms an essential part of the engine bottom-end assembly.
Symptoms Of Wear Or Failure:
- Low engine oil pressure.
- Knocking or rumbling noises from the lower engine.
- Excessive crankshaft movement.
- Metal particles present in the engine oil or oil filter.
- Increased engine vibration.
- Accelerated wear of the crankshaft journals.
- Poor lubrication of internal engine components.
- Engine overheating due to increased friction.
- Loss of engine performance.
- Catastrophic engine failure in severe cases.
Why Replacement Matters:
- The main crankshaft bearings support the crankshaft while maintaining a thin film of pressurised engine oil between the bearing surface and the crankshaft journals. They are subjected to enormous combustion loads, constant rotational forces and continuous lubrication. Over time, normal wear, contamination or insufficient lubrication can damage the bearing surfaces, increasing bearing clearances and reducing oil pressure.
- Worn main bearings can lead to excessive crankshaft movement, reduced lubrication efficiency and accelerated wear of critical engine components. If left unresolved, bearing failure can result in severe crankshaft damage and complete engine failure.
- Replacing worn bearings with the OE Match Main Crankshaft Bearing Set restores the engine's bottom-end integrity, correct bearing clearances and stable oil pressure. Manufactured to OE standards using premium tri-metal bearing construction, this standard-size bearing set provides factory-style fitment, exceptional durability and dependable long-term performance, making it the ideal choice for Porsche engine rebuilds and professional restoration projects.
