Information
Main, thrust & nose bearing Set - STANDARD.
This 15-piece set (12 main bearing shells + 2 thrust bearings + 1 Nose bearing) supports the crankshaft along the crankcase, maintaining ideal oil-film clearance, pressure, and alignment throughout the engine’s life. Manufactured to OEM geometry, the set guarantees perfect crush fit, consistent wall thickness, and stable lubrication under the high temperatures and loads typical of Porsche’s flat-six engines.
Fits:
Porsche 911 - 1978 to 1989
Porsche 964 - 1989 to 1994
Porsche 993 - 1994 to 1997
Porsche 996 turbo - 2000 to 2005
Porsche 996 GT3
Diagram Ref No 22, 23, 24
Ideal for engine rebuilds, restorations, or preventative maintenance, these bearings restore factory-smooth rotation, stable oil pressure, and long-term bottom-end reliability.
• Function: Supports crankshaft rotation and controls axial movement
• Set Contents: 15 pieces (12 main + 2 thrust bearings +1 nose bearing )
• Replacement Interval: During engine rebuild or low oil pressure service
• Benefits: OEM fit, precise clearances, stable lubrication, quiet operation

These high-quality bearings resist wear, maintain stability under loading, and reduce friction. The shoulder shell is designed to handle axial load and keep the shaft from shifting. Both shells are matched to OE tolerances for crush and thickness to preserve ideal oil film clearance and ensure long life.
• Location: Inside the engine case, at the intermediate shaft bore, flanking the connecting housing
• Function: Provides radial support and axial control (shoulder shell) for the intermediate shaft
Over time, the intermediate shaft bearing shells may wear, lose geometry, or develop surface fatigue. Symptoms of failure include increased endplay (shaft axial movement), chain rattle, timing variation, and rapid wear of adjacent sprockets or tensioners.
This pair should be replaced during any engine rebuild, crankshaft pull, or when measurements show endplay outside specification. Installing fresh shells restores proper shaft location and timing stability for durable performance.

Fits:
Porsche 911 - 1984 to 1989
Porsche 911 (930) turbo - 1978 to 1989
Porsche 964 - 1989 to 1994
Diagram Ref No 20.
The OE Match bearing set is ideal for professional engine rebuilds, restorations, or performance refreshes, restoring reliable oil pressure and long-term bottom-end integrity.
• Function: Provides oil film support and crankshaft bearing surface
• Set Contents: 12 bearing shells (6 connecting rods)
• Replacement Interval: At rebuild or low oil pressure diagnosis
• Benefits: Restores oil pressure, eliminates knock, prevents crank damage
• Installation: Direct-fit standard size bearings; verify journal clearance before fitting
Over time, rod bearings wear due to high RPM loads, heat cycles, and oil contamination. Worn bearings can lead to:
• Low oil pressure or flickering oil light
• Knocking or vibration from the crankshaft
• Metal particles in the oil during servicing
Replace bearings:
• During every engine rebuild or crankshaft regrind
• When oil pressure readings drop below specification
• After high-mileage or track use to prevent bottom-end failure
New bearings restore correct oil clearance, stable lubrication, and quiet, balanced engine operation.

• Position: Connecting rod big-end journals
• Function: Maintains oil film clearance and crankshaft rotation stability
• Symptoms of Failure: Low oil pressure, engine knock, metal debris in oil
• Replacement Interval: During rebuild or low oil pressure diagnosis
• Benefits: OEM fit, stable lubrication, high load resistance, quiet operation
• Set Contents: Complete set for one engine (6 cylinders)
Rod bearings gradually wear due to high-speed loading, heat, and oil contamination.
Excessive clearance or bearing wear can lead to:
• Low oil pressure Metallic noise or “rod knock”
• Engine vibration or bearing seizure
Replace bearings:
• During every engine rebuild or crankshaft regrind
• If metal particles are found in oil
• When oil pressure is below specification or knocking occurs
Installing a new bearing set restores correct oil clearance, stable pressure, and long-term bottom-end reliability.

Information
SET OF 12 connecting rod bearing shells - standard size.
Connecting-rod bearing shell replaces the factory big-end bearing used on classic air-cooled Porsche flat-six engines 911 SC 3.0L. It supports the rod big end on the crankshaft journal, creating a hydrodynamic oil film for low-friction rotation and stable oil pressure.
Fits:
Porsche 911 SC 3.0L 1978 - 1983
Diagram ref no 20
Manufactured to OEM dimensions and surface finish, these shells deliver precise crush fit, correct oil-groove geometry, and durable overlay materials for long service life. Install in matched pairs per rod during rebuilds.
• Fits inside the connecting rod big end around the crank journal; one upper + one lower shell per rod.
• Maintains oil film, controls clearance, and protects the crank journal under load.
Rod bearings gradually wear due to mileage, heat, and oil starvation, leading to scoring, uneven surfaces, and reduced oil pressure — all of which increase the risk of rod knock. They should be replaced whenever the engine bottom end is opened, during rebuilds, or if low oil pressure, metallic debris in oil, or audible knocking is detected — a standard preventive step in engine service.

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.
