Main bearings are precision internal engine components located between the crankshaft main journals and the engine crankcase. Their purpose is to support the crankshaft while allowing it to rotate smoothly on a controlled film of pressurised engine oil. Correct bearing clearances are essential for maintaining lubrication, controlling crankshaft movement, reducing friction, and protecting the crankshaft and crankcase from excessive wear.

Main bearings are precision internal engine components located between the crankshaft main journals and the engine crankcase. Their purpose is to support the crankshaft while allowing it to rotate smoothly on a controlled film of pressurised engine oil. Correct bearing clearances are essential for maintaining lubrication, controlling crankshaft movement, reducing friction, and protecting the crankshaft and crankcase from excessive wear.
What This Product Does:
- Supports the crankshaft within the engine crankcase.
- Provides a precision running surface for the crankshaft main journals.
- Allows the crankshaft to rotate smoothly on a lubricating oil film.
- Helps maintain correct crankshaft alignment.
- Controls radial crankshaft movement.
- Helps control crankshaft end float where applicable.
- Reduces direct metal-to-metal contact and friction.
- Supports correct engine oil clearances and lubrication.
- Protects crankshaft journals against excessive wear.
- Withstands substantial combustion and rotational loads.
- Replaces worn or damaged main bearings during an engine rebuild.
- Is intended for compatible Porsche 356C and Porsche 912 engine applications.
Symptoms Of Wear Or Failure:
- Low engine oil pressure.
- Oil pressure becoming particularly low when the engine is hot.
- Deep knocking or rumbling noises from the lower engine.
- Excessive crankshaft movement or end float.
- Metallic particles or bearing material in the engine oil.
- Metallic debris in the oil filter or strainer.
- Excessive main bearing clearance during engine inspection.
- Scoring or abnormal wear of the crankshaft journals.
- Scratched, pitted, or discoloured bearing surfaces.
- Evidence of bearing overheating or oil starvation.
- Uneven or accelerated crankshaft journal wear.
- Serious internal engine damage in advanced cases.
Why Replacement Matters:
- Main bearings are fundamental to the reliability of the engine because they support and locate the crankshaft every time the engine operates. Combustion forces place considerable loads on the crankshaft, and the bearings must maintain a precise lubricated clearance while allowing smooth rotation.
- As main bearings wear, the clearance between the bearing surface and crankshaft journal can increase. Excessive clearance can reduce oil pressure, increase crankshaft movement, and accelerate wear of both the bearings and crankshaft journals. This can eventually result in knocking, poor lubrication, and deterioration of other internal engine components.
- Severe bearing wear can cause the protective oil film to break down, resulting in direct metal-to-metal contact. This may generate excessive heat, score or damage the crankshaft, contaminate the lubrication system with bearing material, and potentially cause major engine failure.
- Correct bearing sizing is especially important when rebuilding a classic Porsche 356C or Porsche 912 engine. Previous crankshaft grinding or crankcase machining can change the required bearing dimensions, meaning a standard-size bearing set may no longer provide the correct running clearance.
- Replacing worn components with the correctly sized OE Match Main Bearing Set – 61610013895A, 61610013895AO1, 616100138100A, or 61610013890A – for Porsche 356C / 912 helps restore correct crankshaft support, oil clearance, lubrication, and dependable engine performance.

About Engine Bearings / Shells
OEMatch Engine Bearings / Shells — Durability, Sealing, Performance
OEMatch engine bearings / shells for Porsche models are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable. Shell bearings support crankshaft and connecting rod rotation, maintain oil clearance and distribute combustion loads to protect internal components.
Available Types- Big end (connecting rod) bearings
- Thrust bearings
- Main and journal bearing shells
Understanding OEMatch Engine Bearings / Shells
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original engine bearings / shells.
OE (Original Equipment) refers to parts matching original specifications for the engine bearings / shells and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM engine bearings / shells engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.

Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM engine bearings / shells engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch provides a wide selection of Porsche parts, including engine items, and maintains thousands of part numbers and cross-references to support rebuilds and restorations.
- Restores correct oil clearance and lubrication
- Reduces knocking and vibration from worn journals
- Prevents crankshaft scoring and internal wear
- Oil starvation or sustained low oil pressure
- Contaminated or degraded engine oil introducing abrasive particles
- Incorrect clearance, poor installation or worn mating journals
The Importance of Replacing with OEMatch Engine Bearings / Shells
Replacing worn shell bearings during an engine rebuild or repair protects the crankshaft and block from scoring, restores reliable oil pressure and film strength, and supports consistent operation across varying loads and temperatures in Porsche engines. Timely replacement reduces the risk of secondary damage and helps preserve engine life.
Advantages
- Tri‑metal and bi‑metal alloy options for thermal stability
- Precision-machined tolerances to maintain oil film and clearance
- Suitable for a wide range of air-cooled and water-cooled Porsche engines
Support & Advice
Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
